WEEK 3 QUIZ v3 |Elaborated| NURS 6521 - Advanced Pharmacology-Walden University NURS 6521 - Advanced Pharmacology-Walden University- WEEK 3 QUIZ v3A nurse has administered a medication to a patient wi... th hypertension. The prescribed drug is supposed to decrease cardiac output. A decrease in cardiac output would most likely Response Feedback: Decrease the amount of circulating blood sent through the kidneys 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 2 1 out of 1 points A nurse is the cardiac care unit is preparing to hang an intravenous dose of dofetilide (Tikosyn) for a patient who has just been admitted. What is the most likely goal of this intervention? Response Feedback: To convert the patient's atrial fibrillation to normal sinus rhythm Dofetilide is used to convert patients in atrial fibrillation to normal sinus rhythm and maintain them in sinus rhythm. This drug is not used in the treatment of bradycardia, heart failure, or ventricular arrhythmias. Question 3 1 out of 1 points A 77-year-old patient has a long-standing history of hypertension, a health problem that is being treated with metoprolol and a thiazide diuretic. Before administering the 8 AM dose of these medications, what assessments should the nurse perform and document? (Select all that apply.) Response Feedback: Heart rate, Blood pressure Because of its effects on blocking beta-1 receptors, metoprolol slows the heart rate, the speed of conduction, and decreases the force of contraction, thus cardiac output is decreased, Drone IT NURS 6521 - Advanced Pharmacology-Walden University- WEEK 3 QUIZ v3 decreasing blood pressure. Consequently, it is necessary to assess the patient's heart rate in addition to his or her blood pressure. Neither beta blockers nor thiazide diuretics create a direct need for the assessment of temperature, respiratory rate, or oxygen saturation level. Question 4 1 out of 1 points An expected outcome for a patient who has just taken sublingual nitroglycerin should be Response Feedback: Increased heart rate and decreased blood pressure Nitroglycerin relaxes vascular smooth muscle and dilates both arterial and venous vessels. Dilation of veins is more predominant than dilation of arteries, resulting in peripheral pooling of blood and decreased preload. Blood pressure will usually decrease as a result of the venous dilation. Reflex tachycardia usually follows the drop in blood pressure. Question 5 1 out of 1 points Several months of treatment with a statin accompanied by lifestyle modifications have failed to appreciably improve a patient's cholesterol levels. Consequently, the patient has been prescribed cholestyramine. The nurse should recognize that this drugs achieves its therapeutic effect by Response Feedback: Oxidizing cholesterol to bile acids Unlike statins, which work by decreasing the synthesis of cholesterol, the bile acid sequestrants such as cholestyramine promote the oxidation of cholesterol to bile acids. Bile acid sequestrants do not promote vasodilation or bind HDL to LDL [Show More]
