NURS 6521 Week 3 Quiz, QUESTIONS AND ANSWERS, WITH DETAILED RESPONSE FEEDBACK (Scored 21/25)

Document Content and Description Below

• Question 1 1 out of 1 points A patient is admitted to the emergency department with severe chest pain. The emergency department physician orders intravenous nitroglycerin 5 mcg/min, titrate ... dose by 5 mcg/min every 3 to 5 minutes per infusion pump as needed. Before administering the nitroglycerin, the nurse should prioritize which of the following assessments? Response Feedback: Before administering IV nitroglycerin, the nurse should first assess blood pressure to make sure that the patient does not have hypotension and to establish a baseline blood pressure. It is also important to assess the heart rate and urinary function (urinary output and BUN). However, in the case of administering intravenous nitroglycerin, the nurse would first assess the blood pressure. • Question 2 1 out of 1 points A 39-year-old African-American male is 25 pounds overweight and has been diagnosed with hypertension after three consecutive above-normal blood pressure readings. The most likely initial drug therapy for this patient will be Response The patient would most likely be prescribed a diuretic in combination with Feedback: diet and other lifestyle changes. African-American men are at increased risk for developing hypertension and tend to respond differently to antihypertensive therapy. The research shows that African-American men are most responsive to single-drug therapy and diuretics. The use of a calcium channel blocker and/or alpha-adrenergic blocker would follow if he is unresponsive to the diuretic in combination with diet and other lifestyle changes. African Americans tend to be less responsive to ACE inhibitors and beta blockers. • Question 3 1 out of 1 points A nurse has administered a medication to a patient with hypertension. The prescribed drug is supposed to decrease cardiac output. A decrease in cardiac output would most likely Response Feedback: A drug-induced decrease in cardiac output would cause a decrease in the amount of circulating blood sent through the kidneys. If a patient has normal kidney function, a decrease in cardiac output would not result in an increased serum creatinine level. Further, the decrease in cardiac output would not cause an increased synergistic effect of the drug, nor would it decrease drug absorption in the blood. • Question 4 1 out of 1 points A nurse who provides care in a busy clinic is aware of the high incidence and prevalence of hyperlipidemia and the consequent need for antihyperlipidemics in many patients. Treatment of high cholesterol using statins would be contraindicated in which of the following patients? Response Feedback: Active liver disease is a contraindication to the use of statins. As well, heavy alcohol use increases the risk of liver dysfunction. Respiratory disease, recent surgery, and organic cognitive deficits do not preclude the use of statins for high cholesterol.
