Examples include taking folic acid while pregnant to prevent neural tube defects, vaccinating children to prevent communicable disease, eating healthy and exercising to prevent heart disease, and wearing seatbelts or helmets. Question 15 10 / 10 pts Explain apoptosis and why it is necessary: Your Answer: apoptosis is the programmed of cell death.this process is necessary for cell dividing because it is removing unwanted cells to make way for new cell. Apoptosis is programmed cell death. This process eliminates cells that are worn out, have been produced in excess, have developed improperly, or have genetic damage. Apoptosis is also responsible for several normal physiologic processes, like replacing cell in the intestinal villi and removing aging red blood cells. Question 16 10 / 10 pts Explain what necrosis is and give an example and description of one type of necrosis. Your Answer: necrosis is when cell dies in an organ/tissues that is still alive .this process can interferes with the tissue regeneration and how cell can be replace. one type of necrosis is gengrenouse necrosis which can bowel or the lower extremities that may causes changes in tussue and it functions Necrosis refers to cell death in an organ or tissues that is still part of a living person. It often interferes with cell replacement and tissue regeneration. Coagulative necrosis results most often from a sudden cutoff of blood supply to an organ (ischemia), particularly the heart and kidney. Liquefactive necrosis occurs when some of the cells die but their catalytic enzymes are not destroyed. It is commonly seen with brain infarcts or abscesses. Caseous necrosis occurs as part of granulomatous inflammation and is most often associated with tuberculosis. Gangrenous necrosis most often affects the lower extremities or bowel and is secondary to vascular occlusion. The term gangrene is applied when a considerable mass of tissue undergoes necrosis. In dry gangrene the affected tissue becomes dry and shrinks, the skin wrinkles, and its color changes to dark brown or black. The spread of dry gangrene is slow. It results from a cut off in arterial blood supply and is a form of coagulation necrosis. In wet gangrene, the affected area is cold, swollen, and pulseless. The skin is moist, black, and under tension. Blebs form on the surface, liquefaction occurs, and a foul odor is caused by bacterial action. The spread of tissue damage is rapid.

Pick 2 and give a description and example of each. Your Answer: nervours tissue-can be find throughout the body and it's used for communication. muscle tissue connective tissue epithelial-(covers the outer surface of the body and lines the inner surfaces. Epithelial tissue covers the body’s outer surface, lines the inner surfaces, and forms glandular tissue. Epithelial tissue has three distinct surfaces and the basal surface is attached to an underlying basement membrane. It is avascular, meaning without blood vessels. It receives oxygen and nutrients from the capillaries of the connective tissue on which it rests. Connective or supportive tissue is the most abundant tissue in the body. It connects and binds or supports the various tissues. Its cells produce the extracellular matrix that support and hold tissues together. Connective tissue is divided into two types: connective tissue proper and specialized connective tissue (cartilage, bone, and blood cells). The four types of connective tissue proper are loose (areolar), adipose, reticular, and dense connective tissue. The function of muscle tissue is to move the skeletal structures, pump blood through the heart, and contract the blood vessels and visceral organs. Muscle tissue can accomplish this by contraction. The two types of fibers that contract are called thin and thick filaments. Thin filaments are called actin, and the thick filaments are myosin. The three types of muscles tissue are skeletal, cardiac, and smooth. Nervous tissue is distributed throughout the body for communication. It provides the means for controlling body function and for sensing and moving about the environment. b. Radiation injury c. Chemical injury d. Biologic agents The two types of cells are neuron and glial cells. Neurons function is communication. Glial (meaning glue) cells support the neurons. Question 19 2.5 / 2.5 pts What term means “cell eating” and engulfs and then kills microorganisms or other particulate matter? Your Answer: cell eating is refered to phagocytosis Phagocytosis Question 20 2.5 / 2.5 pts What term means “cell drinking,” and engulfs small solid or fluid particles, as seen with proteins and electrolytes? Your Answer: cell drinking is refrered to pinocytosis Pinocytosis Question 21 2.5 / 2.5 pts Give one function of a membrane potential: Your Answer: membrane potential can causes music contractions Generate nerve impulse, muscle contractions, or cause hormone secretion Question 22 2.5 / 2.5 pts What is the term that best describes the following process? A transport protein aiding a lipid insoluble or large molecule across the cell membrane that would otherwise not be able to pass through on its own. Your Answer: Facilitated diffusion facilitated diffusion Exam 2 Question 1 3 / 3 pts True/False: Blood tests for tumor markers can make a diagnosis of cancer. Why or why not? Your Answer: false,because tumor are usually elevated in benign conditions ,and in the early stages of malignancy they can't be elevated. False, only tissue can diagnose. Tumor markers are helpful to assess response to therapy or reoccurrence. Question 2 3 / 3 pts What is the most important procedure in diagnosing the correct cancer and histology? Your Answer: tissue biopsy because they play a critical role in dignosing the right cancer and histology tissue biopsy Question 3 4 / 4 pts Explain the TNM system: Your Answer: is a staging system that was created by AJCC for the help study cancer.It is also very effective in classifieng cancers tumor componments. Classification goes as such: T relates to the local spread of the primary of the tumor and the size N relates to the involvement of the regional/location of the lymph nodes M is the extent of the metastatic invilvement T is the size and local spread of the primary tumor. N is the involvement of the regional lymph nodes. M is the extent of the metastatic involvement. Question 4 10 / 10 pts 1. List two signs or symptoms a patient may present with that might indicate a cancer diagnosis: 2. What are two side effects commonly experienced by cancer patients? Your Answer: 1) Bleeding and weight loss 2) hair loss and sleep disturbances 1. Bleeding; sore that doesn’t heal; fluid in the pleural, pericardial, or peritoneal spaces; chest pain, shortness of breath, cough, abdominal discomfort or swelling. Other possible answers can include a mass or lump, pain (need to be specific), fatigue, fevers, weight loss 2. Weight loss, wasting of body fat and muscle tissue, weakness, anorexia, and anemia, fatigue, sleep disturbances Question 5 10 / 10 pts 1. What are the three possible goals of cancer treatment? 2. How does radiation kill cancer cells? Your Answer: 1) the three goal is to curative,control and palliative 2) radiation kill cancer cells by using high energy/waves particles to destroy/damage cancer cells.However this treatment can sometimes interrupt the cells cycle by killing good cells or damaging DNA cells 1. Curative, control, palliative 2. Radiation therapy uses high-energy particles or waves to destroy or damage cancer cells. This leads to the creation of free radicals, which damage cell structures. Radiation can interrupt the cell cycle process, kill cells, or damage DNA in the cells. Question 6 2.5 / 2.5 pts True/False: Cell proliferation is the process in which proliferating cells become more specialized cell types. True Correct! False False, cell differentiation Question 7 0 / 2.5 pts True/False: Cell differentiation is the process in which proliferating cells become more specialized cell types.

Why do tumors need it? Your Answer: angiogenesis is the delovement of new blood vessels with a tumor and tumorns need angiogenesis to grow development of new blood vessels within the tumor. They need it to continue to grow. Question 11 3 / 3 pts What are normal genes called that become cancer-causing if mutated? Your Answer: proto-oncogenes protooncogenes Question 12 3 / 3 pts What is a tumor suppressor gene? Give one example. Your Answer: they're gene that are associated with gene underactivity because of this it slows down cell division or may tell cell when to die. Tumor suppressor genes are associated with gene underactivity. These genes slow down cell division, repair DNA mistakes, or tell cells when to die. BRCA1 or 2, TP53 Question 13 10 / 10 pts A 40-year-old woman has experienced heavy menstrual bleeding. She was told she has a uterine tumor called a leiomyoma. She is worried she has cancer. What do you tell her? Explain at least 2 differences between a benign and malignant tumor. Your Answer: I will tell her not to worry because leiomyoma is a non-cancerous tumor and it can be surgically remove and to always have a regular doctor visit two differences between a benign and malignant tumor is that has a well-differentiated cells and have slow progressive growth rate.Malignant tumor is more aggressive because it destroy tissue,grows rapidly and spread to other body parts and lacks well defined margins Leiomyoma is a benign tumor. (Leiomyosarcoma is malignant) Student can add any of the following: Benign tumors are well-differentiated cells, resemble the cells of tissues of origin, and have a slow, progressive rate of growth. They grow by expansion and remain localized to their site of origin, not capable of metastasizing. They develop a rim of connective tissue around the tumor called a fibrous capsule, which aids in surgical removal. Benign tumors are less of a threat unless they interfere with vital functions Malignant neoplasms invade and destroy tissue. They grow rapidly, spread to other parts of the body, and lack well-defined margins. They can compress blood vessels and outgrow their blood supply, causing ischemia and tissue injury. Surgery can be more difficult if it has spread. Question 14 10 / 10 pts A 62-year-old man with a 30-pack year smoking history is diagnosed with small cell lung cancer with metastasis to the bone. (1) Explain the process of how cancer spreads metastatically. (2) What symptoms might he have presented with? (3) Which screening test would he have benefited from? Your Answer: 1) cancern that are spreads by metastatically is loose from the primary tumor that have extracellular matrix from the surrounding tumor,or has gain access to the blood vessle which it can grow and establish a blood supply. 2 some symptoms that may be presented are shortness of breath,chest or bone pain and cough 3) hw benefited from low dose chest CT that could be done yearly (1) Metastasis- a cancer cell must break loose from the primary tumor, invade the surrounding extracellular matrix, gain access to a blood vessel, survive its passage in the bloodstream, emerge at a favorable location, invade the surrounding tissue, begin to grow, and establish a blood supply. (2) Chest pain, shortness of breath, cough, bone pain. (3) Yearly low-dose chest CT. Question 15 1.5 / 3 pts Malignant tumors have which of the following characteristics? Select all that apply. Correct! Variable rate of growth Correct! Spreads by metastasis Well-differentiated cells You Answered Fibrous capsule Question 16 0 / 3 pts What are molecular and cellular mechanisms in genes that increase susceptibility to cancer? Select all that apply. Correct Answer Lack of cellular senescence Correct! Angiogenesis You Answered Ability to undergo apoptosis Correct! Mutations in growth factor signaling pathways You Answered Intact DNA repair genes Question 17 4 / 4 pts List 4 of the 7 risk factors linked to cancer as stated in the module. Your Answer: 1)obesity 2)hormonal factors 3)environmental agents 4) cancer causing viruses Heredity, hormonal factors, obesity, immunologic mechanisms, environmental agents such as chemicals, radiation, and cancer-causing viruses. Question 18 10 / 10 pts List three characteristics of cancer cells and briefly explain what it means: Your Answer: cancer cells grow in an altered cell differentiation and growth which can also be called neoplasia they can have a neoplasm growth where normal tissue lacks regulatory controls cancer cells also have genetic abnormalities that causes uncontrollble proliferation and can cause normal call or benign tumors into malignant tumors Answer: Any of the following Anaplasia is the loss of cell differentiation in cancerous tissue. Genetic instability means they have a high frequency of mutations. Growth factor independence means cancer cells can proliferate even in the absence of growth factors. Cell density-dependent inhibition means cancer cell don’t stop growing when they come into contact with each other. Cell cohesiveness and adhesion means they don’t stick together. Anchorage dependence means cancer cells aren’t anchored to neighboring cells or the underlying matrix to live and grow. Cell-to-cell communication in cancer cells is poor, which interferes with intercellular connections and responsiveness to membrane-derived signals. Life span is unlimited – cancer cells are immortal. Antigen expression -cancer cells contain several cell surface molecules or antigens that are immunologically identified as foreign. Cancer cells can produce enzymes, hormones, and other substances that the tissues of origin either does not produce or produces in much smaller amounts. Cancer cells can show cytoskeletal changes or abnormalities. This includes abnormal intermediate filament types or changes in actin filaments and microtubules that help with invasion and metastasis. Question 19 3.5 / 3.5 pts Which of the following is not a risk factor for developing cancer? Correct! Sunscreen Obesity HPV High red meat intake Question 20 3.5 / 3.5 pts All of the following viral agents are correctly paired with the associated lesion except: Human papillomavirus (HPV): genital warts Correct!

Hepatitis B virus: hepatocellular carcinoma Human herpes virus-8: Kaposi sarcoma Question 21 3 / 3 pts List one example of screening for each method: observation, palpation, and lab test/procedure: Your Answer: observation-external genitalia palpation-lymph nodes lab test/procedure-pap smear Observation: skin, mouth, external genitalia Palpation: breast, thyroid, rectum and anus, prostate, lymph nodes Laboratory tests and procedures: Pap smear, colonoscopy, mammography Exam 3 Question 1 5 / 5 pts Short answer Explain the challenges of diagnosing autoimmune disorders. Your Answer: since there are too many autoimmune disorder,diagnosing is made by serological finding,history or physical testing.blood testing could have been a good way to test but since some blood are more generic can be elevated to show other diseases therefore it best go by finding that are listed. There are over 80 identified, many with overlapping presentations. Many manifestations are nonspecific and are seen in other non-autoimmune diseases. Blood testing isn’t perfect either, as some tests are more generic and can be elevated in the presence of other diseases. Question 2 2.5 / 2.5 pts Multiple choice: Which cell is the first responder to phagocytose a foreign invader? Correct!

Your Answer: it can be a cause od Type I hypersensitivety/ IGE as well as allergy, which is responisible for her symptoms and treatment such as penicillin or some allergy medications (1) Mast cells, basophils, and eosinophils play an important role in the development of type I reactions because they contain the chemical mediator histamine. A primary or initialphase response is vasodilation, vascular leakage, and smooth muscle contraction. A secondary or late-phase response is characterized by more intense infiltration of tissues with eosinophils and other acute and chronic inflammatory cells, as well as tissue damage. (2) Antihistamines and intranasal corticosteroids are the mainstay of treatment. Question 9 3.5 / 3.5 pts True/False: An antibiotic alone will heal an abscess. If false explain why: Your Answer: false,because there be some pus in there that need ro be drained to make sure that the area don't infected false, antibiotics can’t penetrate the abscess wall, so incision and drainage are necessary. Question 10 3 / 3 pts Multiple Choice: An appendectomy is performed on a 16-year-old boy who is hospitalized for right lower quadrant abdominal pain of 18 hours’ duration.

Ankylosing spondylitis HLA-B27 antigen is found in almost 90% of patients with ankylosing spondylitis Graves’ disease Question 18 5 / 5 pts Short answer: What are autoantibodies? Your Answer: when the immune system don't have the ability to recognize itself and produces autoantibodies that acts againist host tissues Answer: In many autoimmune diseases, the immune system loses its ability to recognize self and produces what is called autoantibodies, which act against host tissues. Question 19 5 / 10 pts 1, A 32-year-old woman presents to the clinic for her initial obstetrics visit, about 10 weeks into her pregnancy. She is in a monogamous relationship. (1) Should an HIV test be part of her initial blood work? Why? 2. An infant is born, and its initial antibody test is positive for HIV. (2) Does this mean the infant is infected? What would be the more appropriate test to detect HIV in this infant? Your Answer: Although she's in a monogamous relationship and have one partner it is still a good idea to test for HIV in her initial blood work because if tested positive,it can be transmet directly to the baby through birth or in the mother milk while breastfeeding. 2) yes,the baby has been infected most likely the virus has been transmission from it's mother,and the most appropriate test to detect HIV in this infants will be to use the DNA/RNA polymerase cain reaction (PCR) becaue the infants would still have ther mother's antibodies 1. Yes. Transmission from mother to infant is the most common way that children become infected. The CDC recommends all people between ages 13 and 64 be routinely screened for HIV. Earlier detection and treatment lead to better outcomes. 2. No. The polymerase chain reaction (PCR) test is a nucleic acid test that can detect HIV DNA. It tests for the presence of the virus, rather than the antibody, which is helpful in diagnosing HIV infection in infants born to infected mothers. These infants would have their mother’s antibodies whether or not they have been infected. Question 20 3.5 / 3.5 pts Multiple Choice: Which of the following will promote wound healing?

Explain how ventricular hypertrophy is an adaptive mechanism: 2. What happens during exercise in someone with coronary artery disease? Your Answer: 1 by increasing the cardica output or physical myocardial changes 2 they might have streangth the heart muscle and improve over all hearth or lower chances of heart attack 1. An increase in wall stress can be caused by an increase in preload or afterload. Ventricular hypertrophy is an adaptive mechanism by which the ventricle can offset the increase in wall stress. OR Blood pressure elevation increases the workload of the left ventricle by increasing the pressure against which the heart must pump as it ejects blood into the systemic circulation. Over time, the left ventricle hypertrophies to compensate for the increased pressure and work. 2. During exertion, the heart beats harder and faster to supply oxygen to the muscles. The coronary vessels vasodilate and increase blood flow to the cardiac muscle to meet its increased demand for oxygen. With atherosclerotic disease, the coronary vessel lumens are narrowed and blood supply to the heart is diminished. With exertion, the vessels cannot adequately vasodilate. This can manifest as chest pain or tightness and/or shortness of breath. Question 19 10 / 10 pts 1. Hypertension is often called “the silent killer.” By the time symptoms of hypertension occur, the complications can affect the kidneys, heart, eyes, and blood vessels. What is this term called? 2. Left ventricular hypertrophy is a major risk factor for what other diseases? Name at least 2. Your Answer: 1 Target organ damage 2 it can cause heart diseases such as heart attack or storke 1. Target-organ damage 2. coronary heart disease, cardiac dysrhythmias, congestive heart failure, and sudden death. Question 20 2.5 / 2.5 pts Multiple Choice: With increasing occlusion of the coronary vessel(s), the demands of the resting heart may become too great. When the patient experiences angina without exertion, or when the level of exertion necessary to cause anginal symptoms decreases, this is called what? Stable angina Correct!

Presents with decreased respiratory rate Decreased surfactant function Increased capillary permeability Question 15 10 / 10 pts Short answer: A 10-year-old boy who is having an acute asthma attack is brought to the ER. He is observed to be sitting up and struggling to breathe. His breathing is accompanied by use of accessory muscles, a weak cough, and audible wheezing sounds. His pulse is rapid and weak, and both heart and breath sounds are distant on auscultation. His parents relate that his asthma began to worsen after he developed a “cold,” and now he doesn’t get relief from his albuterol inhaler. Explain the changes in physiologic function underlying his signs and symptoms. Your Answer: In most asthma patients there's a airway inflammation from cold virus that causes epithelial injury.Also due to severe airway imflammation this patient is most likely experiencing bronchial hyper-responisiveness which causes airway obstruction or narrowing. However, this changes can cause fixed obstruction in asthma patients which is not reversible event with the used of inhalers or bronchodilaters Recruitment of inflammatory cells from the bloodstream into the bronchial wall, where they directly attack the invading organisms and secrete inflammatory chemicals that are toxic to the organisms causes airway inflammation. Swelling of the bronchial wall, mucus secretion, constriction of the airway; bronchial hyper-responsiveness to stimuli causes airway obstruction or narrowing. They may discuss on a cellular level as well: Upon a trigger, the cascade of neutrophils, eosinophils, lymphocytes, and mast cells cause epithelial injury. This causes airway inflammation, which further increases hyperresponsiveness and decreased airflow. Mast cells release histamine and leukotrienes. These cause major bronchoconstriction, inflammation, and mucus secretion. Mast cells can trigger multiple cytokine release, which causes more airway inflammation. The contraction of the airways and subsequent swelling leads to further airway obstruction. Question 16 10 / 10 pts Short answer: When is the risk for obstructive atelectasis the greatest? What are strategies to decrease the chance for developing atelectasis? Your Answer: the risk is greatest following surgery because anesthesia pain medication and immobility may help to develope bronchial secretions. strategies such as frequently coughing,taking deep breath,hydrate adepuately and changes positions may decrease the chance for atelectasis The risk of obstructive atelectasis is increased following surgery. Anesthesia, pain and pain medications, and immobility promote retention of bronchial secretions. Patients are encouraged to frequently cough, deep breath, change positions, hydrate adequately, and ambulate early to prevent atelectasis. Question 17 10 / 10 pts Short answer: Explain why the oxygen flow rate for people with COPD is normally titrated to maintain the arterial PO2 between 60 and 65 mm Hg. Your Answer: Because their medullary respiratory center is now fuction at a elevated Co2 level and can't not responds to increase in PCO2.when there is a decrease in PO2 it become a stimulus for but if there is a higher rate of oxygen,it would suppresses respiratory drive and respiration stimulus levels and no longer 2 Their medullary respiratory center has adapted to the elevated CO becomes the stimulus for 2 . Therefore, a decrease in PO 2 responds to increases in PCO respiration. If oxygen is given at too high of a rate, it suppresses the stimulus and the respiratory drive.

Explain why pancreatitis would lead to this imbalance. Your Answer: Dehydration Pancreatitis would lead to dehadration due to water output that has been exceed by water intake Answer: Hypocalcemia. Acute pancreatitis causes the release of proteolytic and lipolytic enzymes. Free fatty acids are released during lipolysis in the pancreas. Ca2+ binds to these fatty acids removing them from the blood. Question 22 5 / 5 pts Short Answer: A patient has a diagnosis of glomerular disease. Given what you know about the structural framework of the glomerular capillaries, what would be detected in this patient’s urine, and explain why this would happen. Your Answer: the urine will have blood and protein due to lock of prevention of red blood cells and plasma proteins which is provent by the glomerular capillaries from passing through the glomerular membrane into the filtrate is no longer being block from passing through Answer: Blood and protein may be present in the urine. Spaces within the basement membrane of the glomerular capillaries, under normal circumstances prevent red blood cells and plasma proteins from passing through the glomerular membrane into the filtrate. The disease process would compromise this. Question 23 5 / 5 pts Short Answer: A patient with chronic kidney disease must undergo dialysis treatments as they wait for transplantation. Give 1 reason peritoneal dialysis would be preferable to the patient over hemodialysis and 1 concern in choosing peritoneal dialysis over hemodialysis. Your Answer: Preitoneal dialysis is preferable for the patient because it can be done in the patient's home which reduces patient going to dialysis clinic.However, there is a high risk for infection at the catheter site with preoitoneal dialysis Answer: Peritoneal dialysis can be done in the patient’s home as opposed to going to a dialysis clinic multiple times per week. A major concern of the utilization of peritoneal dialysis is the risk for infection at the catheter site. Question 24 10 / 10 pts A patient presents to the emergency department with complaints of sharp pain that comes in waves in the upper lateral quadrant of the abdomen.

Your Answer: the tedons and ligament works by promoteing movment of the body and connect bones and nuscles.when there is increase strech or torsional strain,there will be an reflexive response cause by nerve fibers which causes tension on the muscles protecting joints and capsule which has the tension The tendons and ligaments of joints serve in proprioception (the awareness of ones’ position in space or movement of the body). When these structures undergo stretch or torsional strain, these proprioceptive nerve fibers will cause a reflexive response to adjust the tension on the muscles (to maintain balance and not fall over) that support the joint protecting the capsule and other joint structures. Question 18 5 / 5 pts A patient presents to the ER with severe pain in their right ankle. Blood tests reveal serum uric acid levels of 7.8 mg/dL. They are kept for observation and their 24-hr urine specimen reveals underexcretion of urate. Which phase of gout are they in? What is the goal of your treatment given the phase they are in? Your Answer: this patients is most likely in phase 2 of gout/acute gout arthritis Treatment helps to manage symptoms and reduces theinflammation by used og NSADS drugs This patient is in phase 2 of gout or acute gout arthritis. The goal of treatment is to manage symptoms and terminate the acute attack primarily through NSAIDS. Question 19 5 / 5 pts Which of the following patients is at greater risk for developing osteoporosis and sustaining a fracture? Explain how you came to your conclusion. Patient A. is a 75-year-old white Caucasian male who has a history of a distal radius fractures at age 65. Patient B. is a 60- year-old African American female who is postmenopausal. She is active and does not have a history of fractures. Your Answer: Patient A is at higher risk due to his age over 70,and has a history of bone fractures Patient A is at higher risk. Even though he is a male, he is advanced in age, white Caucasian, and sustained a fracture after the age of 50. Patient B is a postmenopausal female; however, she is active and of African American decent which is associated with high BMD and low rates of fracture. Question 20 5 / 5 pts A 60-year-old, obese female works out of her home and rarely walks due to the sedentary nature of her job. Give 2 reasons why she is at increased risk for developing OA. Your Answer: due to immobilization( the patient can rarely walks) can compromise iubrication of the joint which will cause more weight on the joint that can lead to joints structural changes She is a female over the age of 55; she is obese, and she is relatively sedentary which contributes to the decreased nourishment of the joint that comes with weight bearing and range of motion. (*Note - student only needs to provide 2 reasons.) Question 21 5 / 5 pts Compare and contrast the blood supply of cortical bone and cancellous bone. Your Answer: cortical bone has a direct bone supply which perfortating and nutrient the arteries.Blood passes through the central haversion and volkmann canals. Cancellous bone does not have a direct blood supply,and receive its blood supply from diffusion through the endosteal bone surface extending outward through the canaliculi Cortical bone has a direct blood supply. Nutrient and Perforating arteries form an anastomosis (collateral circulation) that circulates through the bone through the Haversian and Volkmann canals. Cancellous bone does not have a direct blood supply. It receives its blood supply through diffusion from the endosteal bone surface extending outward through the canaliculi. Question 22 5 / 5 pts A 22-year-old competitive gymnast has experienced amenorrhea for the past 5 years. Her PCP is suspecting that she may have premature osteoporosis. Would you expect her OPG levels to be high, normal, or low? Explain why her levels would be at this level. Your Answer: She has a high RANKL levels,because of Estrogen whhich increase the production of OPG that has RANKL.However,lower estrogen levels would lead to lower OPG levels which will increase RANKL and osteoclast activity Her OPG levels would be low. Amenorrhea results in lower estrogen levels. Estrogen increases the production of OPG in turn decreasing osteoclast activity. If estrogen levels are low, OPG levels would also be low resulting in increased osteoclast activity. Question 23 10 / 10 pts A 68-year-old, white Caucasian female has a DEXA scan at the recommendation of her PCP. Her scan yielded a T-score of -2.6. Interpret the results of her DEXA scan. Develop a treatment plan giving a pharmacologic recommendation if applicable (be specific with name of supplement and/or class of drug), and a non-pharmacologic recommendation. Your Answer: The T-score shows a normal bone density but due to patients background such as age,race and gender a calcium supplement or vitamin D and activities such as walking and exercise would be recommend. This T-score indicates osteoporosis. This patient should take a Calcium and Vitamin D supplement. In addition, she should be prescribed one of the following: Estrogen, SERMs, Bisphosphonates, or Calcitonin. She should also participate in regular weight bearing and resistive exercise being careful to choose activities that would not put her at increased risk for falling. Question 24 10 / 10 pts A 72-year-old male is said to be in phase 3 of gout. He is obese and has a history of alcohol abuse. Develop a treatment plan including specific pharmacologic intervention and a nonpharmacologic recommendation to manage his disease. Your Answer: Better treatment plan is to maintain normal uric acid leaves,as well as exercise as lower alcohol intake. diet changes-avoid food that are rich in purine such as bacon,shellfish and fish can help prevent futrue attacks. Phase 3 of gout is called inter-critical gout. The patient is asymptomatic, and no joint abnormalities are present. The goal of treatment in this phase is to maintain normal uric acid levels and prevent progression of the disease. Allopurinol is a prescription drug that is used to reduce uric acid levels. This patient should be encouraged to lose weight and decrease his alcohol consumption. He should also avoid purine rich foods such as fish, bacon, and liver. (*Note – the student has to provide 1 pharmacologic intervention and 1 non-pharmacologic recommendation.) Question 25 10 / 10 pts A patient has a bilateral presentation of pain in the PIP joints of the hands. You believe this pain is due to arthritis but are unsure whether it is a result of RA or OA. What are 3 questions you could ask this patient to help you differentiate between RA and OA? Your Answer: 1-is there any daily pain / pain during activity ? if so,is there any period of relief 32Do you experience of morning stiffness that usually resolives in ess than 30 min or longer? 3-does the pain starts in both hands or start in one hand and delovep to the other hand over time? 1. Do you experience stiffness in the morning? 2. If so, does it last less than or longer than 30 minutes? 3. Does prolonged movement aggravate or alleviate your symptoms? 4. Do you ever have periods of relief, or do you experience pain daily? 5. Did your pain start in both hands or did it start with one hand and develop in the other over time? 6. What is your profession? (occupations requiring repetitive movements often lead to OA) *Note – student only has to provide 3 questions. [Show More]
