Document Content and Description Below

MCQ #1 A 22 year old man is hypotensive and tachycardic after a shotgun wound to the left shoulder. His blood pressure is initially 80/40 mmHg. After 2 liters of crystalloid solution his blood pressur... e increases to 122/84 mmHg His heart rate is now 100 beats per minute and his respiratory rate is 28 breaths per minute. His breath sounds are decreased in the left hemithorax, and after initial IV fluid resuscitation, a closed tube thoracostomy is performed for decreased left breath sounds with the return of a small amount of blood and no air leak. After chest tube insertion, the most approriate next step is a) reexamine the chest b) perform an aortogram c) obtain a CT scan of the chest d) Obtain arterial blood gas analyses e) perform tranesohageal echocardiography the answer is d ; but a website said a (and a makes more sense to me. so i'll go with a) info: chest tube insertion, p.108 ATLS MCQ #3 During the third trimester of pregnancy, all of the following changesoccur normally EXCEPT a a) decrease in PaCO2 b) decrease in leukocyte count c) reduced gastric emptying rate d) diminished residual lung volume e) diminished elvic ligament tension the answer is b. info: page 261 ATLS MCQ #4 In managing the head injured patient,the most important initial step is to a) secure the airway b. obtain c-spine film c) support circulation c) control scalp hemorrhage e) determine the GCS score the answer is a. info: p.154 ATLS MCQ #5 A previously healthy, 70kg (154 pound) man suffers an estimated acute blood loss of 2 liters. Which one of the following statements applies to this patient? a) his pulse pressure will be widened b) his urinary output will be at the lower limits of normal c) he will have tachycardia, but no change in his systolic blood pressure d) his systolic blood pressure will be decreased with a narrowed pulse ressure (true) e) his systolic blood pressure will be maintained with an elevated diastolicpressure the answer is d. info. page 61 ATLS MCQ #6 The physiologic hypervolemia of pregnancy has clinical significance in the management of the severely injured, gravid woman by a) reducing the need for blood transfusion b) increasing the risk of pulmonary edema c) complicating the management of closed head injury d) reducing the volume of crystalloid required for resuscitation e) increasing the volume of blood loss to produce maternal hypotension the answer is e. info. page 261 ATLS MCQ #7 The best guide for adequate fluid resuscitation of the burn patient is a) adequate urinary output b) reversal of systemic acidosis c) normalization of the heart rate d) a normal central venous pressure e) 4mL/kg/percent body burn/24 hours the answer is a. (not sure..) info: pg. 216-217 The adequacy of therapy is confirmed by simple determination of adequate urine output and of the haemoglobin and haematocrit levels. The most important guide is the patient’s clinical response source: http://www.medbc.com/annals/review/vol_16/num_4/text/vol16n4p173.asp ATLS MCQ #8 Establishing a diagnosis of shock must include a) hypoxemia b) acidosis c) hypotension d) increased vascular resistance e) evidence of inadequate organ perfusion the answer is e. the info: p.58 ATLS MCQ #9 A 7 year old boy is brought to the emergency department by his parents several minutes after he fell through a window. He is bleeding profusely from a 6-cm wound of his medial right thigh.Immediate management of the wound should consist of a) application of a tourniquet b) direct pressure on the wound c) packing the wound with gauze d) direct pressure on the femoral artery at the groin e) debridement of devitalized tissue info is: p.79; in obvious external bleeding section on table background - tourniquet can be found on p.194, 195. they imply that you use a tourniquet if you are choosing life over limb, and if direct pressure isn't working. (p.195) ATLS MCQ #10 For the patient with severe traumatic brain injury, profound hypocarbia should be avoided to prevent a) respiratory alkalosis b) metabolic acidosis c) cerebral vasoconstriction with diminished perfusion d) neurogenic pulmonary edema e) shift of the oxyhemoglobin dissociation curve info is: related info on page 136,137 -------- background info Carbon dioxide is perhaps the most potent available modulator of cerebrovascular tone and thus cerebral blood flow (CBF) http://www.liebertonline.com/doi/abs/10.1089/089771501750055776?journal Code=neu ----------- Hypercarbia and hypoxia are both potent cerebral vasodilators that result in increased cerebral blood flow and volume and, potentially, increased ICP; thus, they must be avoided. Orotracheal intubation allows for airway protection in patients who are severely obtunded and allows for better control of oxygenation and ventilation. http://emedicine.medscape.com/article/909105-overview ------------ ATLS MCQ #11 A 25 year old man is brought to a hospital with a general surgeon after being involved in a motor vehicle crash. He has a GCS of 13 and complains of abdominal pain. His blood pressure was 80mHg systolic by palpation on arrival at the hospital, but increases to 110/70 mmHg with the administration of 2 liters of intravenous fluid. His heart rate remains 120 beats per minute. Computed tomography shows an aortic injury and splenic laceration with free abdominal fluid. His blood pressure falls to 70mmHg after CT. The next step is a) contrast angiography b) transfer to higher level trauma center c) exploratory laparotomy d) transfuse packed red blood cells e) transesophageal echocardiography info: page 12 - list background info: none for now ATLS MCQ #12 Which one of the following statements regarding abdominal trauma in the pregnant patient is true? a) the fetus is in jeopardy only with major abdominal trauma b) leakage of amniotic fluid is an indication for hospital admission c) indications for peritoneal lavage are different from those in the nonpregnant patient d) penetration of an abdominal hollow viscus is more common in late than in early pregnancy e) the secondary survey follows a different pattern from that of the nonpregnant patient info: page 265, i've marked it background info: none yet ATLS MCQ #13 The first maneuver to improve oxygenation after chest injury is a) intubate the patient b) assess arterial blood gases c) administer supplemental oxygen d) ascertain the need for a chest tube e) obtain a chest x-ray the info: can't find it! ATLS MCQ #14 A 25 year old man, injured in a motor vehicular crash, is admitted to the emergency department. His pupils react sluggishly and his eyes open to painful stimuli. He does not follow commands, but he does moan periodically. His right arm is deformed and does not respond to painful stimulus; however, his left hand reaches purposefully toward the painful stimulus. Both legs are stiffly extended. His GCS Score is a) 2 b) 4 c) 6 d) 9 e) 12 info: p.138 background info: i used my card on gcs for this. ATLS MCQ #15 A 20 year old woman, at 32 weeks gestation, is stabbed in the upper right chest. In the emergency department,her blood pressure is 80/60 mmHg. She is gasping for breath, extremely anxious, and yelling for help. Breath sounds are diminished in the right chest. The most appropriate first step is to a) perform tracheal intubation b) insert an oropharyngeal airway c) perform needle decompression of the right chest d) manually displace the gravid uterus to the left side of the abdomen e) initiate 2, large-caliber peripheral IV lines and crystalloid infusion info is: p.87 ATLS MCQ #16 Which one of the following findings in an adult [Show More]
