Document Content and Description Below

Question 1 1 out of 1 points An expected outcome for a patient who has just taken sublingual nitroglycerin should be Selected Answer: Correct Answer: B. increased heart rate and decreased blood ... pressure. Response Feedback: 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 2 1 out of 1 points A nurse is caring for a patient who is diabetic and has been diagnosed with hypertension. An angiotensinconverting enzyme inhibitor, captopril, has been prescribed for her. Which of the following should the nurse assess before beginning drug therapy? Selected Answer: Correct Answer: D. Serum potassium levels Response Feedback: Captopril inhibits the angiotensinconverting enzyme that is needed to change the inactive angiotensin I to the active form, angiotensin II. This reduction of angiotensin II decreases the secretion of aldosterone, preventing sodium and water retention. This action decreases peripheral vascular resistance and lowers blood pressure. Serum potassium may increase as a result of decreased aldosterone levels. It would be helpful to have a baseline level at the beginning of the drug therapy to monitor the possible effect of hyperkalemia. There is no need to monitor calcium and magnesium levels. While it is important to always know a diabetic's blood glucose level, captopril does not alter the level during therapy [Show More]
