NURS 6521 - Advanced Pharmacology-Walden University – WK 1 v1NURS 6521 - Advanced Pharmacology-Walden University – WK 1 v1Question 1 1 out of 1 points Tylenol 325 mg/tablet, patient needs 650 mg; ... how many tables should patient take? • Question 2 0 out of 1 points A 60-year-old African-American man lives with a number of chronic health problems. Genetic factors are likely to influence his etiology and/or treatment of Response Feedback: The incidence of hypertension is significantly higher among AfricanAmericans than other ethnic groups. As well, African Americans respond to some antihypertensive drugs differently than whites. • Question 3 0 out of 1 points Which of the following statements best defines how a chemical becomes termed a drug? Response Feedback: Even though all the responses are correct, a chemical must undergo a series of tests to determine its therapeutic value and efficacy without severe toxicity or damaging properties before it is termed a drug. Test results are reported to the FDA, which may or may not give approval. • Question 4 1 out of 1 points The nurse's assessment of a community-dwelling adult suggests that the client may have drug allergies that have not been previously documented. What statement by the client would confirm this? NURS 6521 - Advanced Pharmacology-Walden University – WK 1 v1 Response Feedback: True allergic reactions include formation of rash or hives, itching, redness, swelling, difficulty breathing, and anaphylactic shock. Nausea and vomiting, however, are adverse effects of drug therapy. Similarly, an unsafe drop in blood pressure and gastric bleeding from aspirin use are adverse drug effects, not allergic reactions. • Question 5 1 out of 1 points In light of her recent high blood pressure readings, a patient has been started on a thiazide diuretic and metoprolol (Lopressor), which is a beta-adrenergic blocker. What is the most likely rationale for using two medications to address the patient's hypertension? Response Feedback: A synergistic effect occurs when two or more “unlike” drugs (in terms of therapeutic effect or mechanism of action) are used together to produce a combined effect, and the outcome is a drug effect greater than either drug's activity alone. As a result, the patient's hypertension may be better treated than with a single drug. This does not necessarily reduce the risk of adverse reactions or increase compliance with the regimen. • Question 6 Which of the following affects drug distribution throughout the body? 1 out of 1 points Response Feedback: Both protein binding and altered pH of extracellular fluids affect drug distribution. The presence of food in the gastrointestinal tract affects drug absorption, whereas an increase in hepatic enzymes affects drug metabolism. High blood levels are not known to affect drug pharmacokinetics. [Show More]
