A patient with a substance use disorder is being monitored for withdrawal symptoms.
Which medication might be used to manage alcohol withdrawal?

Choice A rationale

While increasing fluid intake might offer temporary relief for a dry cough, it does not address the underlying cause, which is a common side effect of ACE inhibitors. This cough is due to the accumulation of bradykinin, and fluid intake will not resolve this physiological process, making it an ineffective long-term solution.

Choice B rationale

Reassuring the patient and telling them to continue the medication is unsafe and inappropriate. The ACE inhibitor-induced cough can be very distressing and may indicate an intolerance to the drug. Continuing the medication could lead to non-adherence and does not address the patient's discomfort or the need for an alternative therapy.

Choice C rationale

Advising the patient to stop the medication immediately is not the most appropriate action as it can be dangerous and lead to a rebound of their underlying condition, such as hypertension or heart failure. The nurse should not unilaterally make a decision to discontinue a prescribed medication without consulting the healthcare provider.

Choice D rationale

The most appropriate nursing response is to notify the healthcare provider. The dry cough is a common and often bothersome side effect of ACE inhibitors caused by the buildup of bradykinin. It usually necessitates a change in medication to an alternative, such as an ARB, to address the side effect while maintaining therapeutic benefits.

Choice A rationale

Alpha-adrenergic blockers primarily affect vascular tone by blocking alpha-1 adrenergic receptors, leading to vasodilation. While severe hypotension from these agents could theoretically compromise renal perfusion, renal failure is not a common or direct adverse effect. The primary concern is related to rapid changes in blood pressure, not a direct nephrotoxic effect on the kidneys themselves.

Choice B rationale

Alpha-adrenergic blockers cause vasodilation by inhibiting the sympathetic nervous system's vasoconstrictive effects on arterioles and veins. This leads to a decrease in peripheral vascular resistance and venous return. When the patient stands up, this vasodilation prevents the normal compensatory increase in blood pressure, resulting in a sudden drop in blood pressure and cerebral perfusion, clinically manifested as orthostatic hypotension.

Choice C rationale

Alpha-adrenergic blockers do not typically cause hyperglycemia. In fact, some alpha-1 antagonists have been shown to improve insulin sensitivity and glucose metabolism in patients with insulin resistance. The primary concern with this class of drugs is their effect on blood pressure, not their influence on glucose regulation, as their mechanism of action is distinct from hormonal pathways that regulate blood glucose levels.

Choice D rationale

Alpha-adrenergic blockers primarily act on the peripheral vascular system and have minimal to no direct effect on the respiratory drive centers in the brainstem. Respiratory depression is more commonly associated with central nervous system depressants, such as opioids or benzodiazepines, which act on different receptor systems. Therefore, this adverse effect is not a typical concern with alpha-adrenergic blocker administration.
