A nurse is assessing a client who has heart failure and is receiving metoprolol. Which of the following statements by the client indicates a therapeutic effect of the medication?
“I have less swelling in my ankles.”
“I can walk farther without getting tired.”
“I don’t have chest pain anymore.”
“I can breathe better at night.”.
The Correct Answer is B
The correct answer is choice B. “I can walk farther without getting tired.” This statement indicates a therapeutic effect of metoprolol, which is a beta-blocker that reduces the heart rate, blood pressure, and the workload of the heart. This helps to improve the blood flow and oxygen delivery to the heart and other organs, and reduces the symptoms of heart failure such as fatigue, dyspnea, and edema.
Choice A is wrong because “I have less swelling in my ankles.” This statement indicates a possible effect of a diuretic, which is a medication that reduces fluid retention and edema by increasing urine output. Metoprolol does not have a direct diuretic effect, although it may indirectly reduce fluid accumulation by improving cardiac function.
Choice C is wrong because “I don’t have chest pain anymore.” This statement indicates a possible effect of a nitrate, which is a medication that dilates the blood vessels and reduces the oxygen demand of the heart. Metoprolol may also help to prevent or treat angina by lowering the heart rate and blood pressure, but it is not the primary medication for chest pain relief.
Choice D is wrong because “I can breathe better at night.” This statement indicates a possible effect of an oxygen therapy, which is a treatment that delivers supplemental oxygen to the lungs and improves gas exchange. Metoprolol may also help to reduce dyspnea by improving cardiac function and reducing pulmonary congestion, but it is not the primary treatment for respiratory distress.

Correct Answer is A
Explanation
Mannitol is an osmotic diuretic that increases urine output and decreases intracranial pressure and intraocular pressure. The nurse should check the urine output before giving the medication to ensure adequate renal function and prevent fluid overload and electrolyte imbalance. The normal urine output is 0.5 to 1 mL/kg/hr.
Choice B is wrong because checking the blood pressure is not specific to mannitol administration. Mannitol can cause hypotension or hypertension depending on the fluid status of the client, but this is not the priority action before giving the medication.
Choice C is wrong because checking the blood glucose is not relevant to mannitol administration. Mannitol does not affect blood glucose levels.
Choice D is wrong because checking the oxygen saturation is not related to mannitol administration. Mannitol does not affect oxygen saturation levels.
Correct Answer is E
Explanation
Adrenergic drugs.These are drugs that stimulate the sympathetic nervous system by mimicking or enhancing the effects of epinephrine and norepinephrine, the chemical messengers that activate adrenergic receptors.Adrenergic drugs can increase blood pressure, heart rate, cardiac output, vascular tone, and renin release by acting on different types of adrenergic receptors.
Choice A is wrong because beta blockers are drugs that inhibit the sympathetic nervous system by blocking the beta adrenergic receptors, which are responsible for increasing heart rate and contractility. Beta blockers can lower blood pressure and reduce cardiac workload.
Choice B is wrong because calcium channel blockers are drugs that inhibit the movement of calcium ions across the cell membrane of smooth muscle cells, which are found in blood vessels and the heart.Calcium channel blockers can relax blood vessels and lower blood pressure, as well as reduce heart rate and contractility.
Choice C is wrong because angiotensin II receptor blockers (ARBs) are drugs that block the action of angiotensin II, a hormone that causes vasoconstriction and stimulates the release of aldosterone, which increases sodium and water retention.
ARBs can lower blood pressure by dilating blood
