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 taking a nitroglycerin tablet is a common treatment for angina, it should not be the first action. The immediate priority is to stop the activity causing the increased myocardial oxygen demand. Continuing to exert oneself can worsen myocardial ischemia and potentially lead to a more severe cardiac event, such as a myocardial infarction.

Choice B rationale

The primary action should be to stop the activity immediately and rest. Mowing the lawn is a strenuous activity that increases the heart's workload and oxygen demand. By stopping and resting, the patient decreases myocardial oxygen consumption, which can help alleviate the chest pain and prevent further myocardial ischemia.

Choice C rationale

While moving inside to cool off and get water may seem helpful, it is not the most critical first step. The immediate need is to reduce the cardiac workload, which is best achieved by ceasing the physical exertion. A patient should first sit or lie down to rest, as this action directly addresses the increased oxygen demand.

Choice D rationale

Calling 911 is crucial if the chest pain does not subside with rest or if it worsens. However, it is not the very first action to take. The initial step is always to stop the activity and rest, as this may be sufficient to resolve the symptoms. If the pain persists after resting, then it is appropriate to seek immediate emergency medical help.

Choice A rationale

Reducing physical activity is not a recommended lifestyle modification for enhancing the effectiveness of antihypertensive medication. Regular physical activity, such as aerobic exercise, strengthens the cardiovascular system, helps manage weight, and can directly lower blood pressure, thereby complementing the effects of medication.

Choice B rationale

Increasing dietary sodium intake is detrimental to blood pressure control. High sodium intake leads to increased fluid retention, which raises blood volume and cardiac output, thereby increasing blood pressure. This counteracts the effect of antihypertensive medication and is a known risk factor for cardiovascular disease.

Choice C rationale

Limiting fluid intake is not a universally recommended strategy for all patients on antihypertensive medication. While some conditions like heart failure may require fluid restriction, this is not a general rule for hypertension management. Maintaining adequate hydration is important for overall health and for the proper function of various bodily systems.

Choice D rationale

Maintaining a low-sodium diet and managing weight are two critical lifestyle modifications that enhance the effectiveness of antihypertensive medication. A low-sodium diet reduces fluid retention and blood volume, while weight management decreases the strain on the heart and blood vessels. These actions work synergistically with medication to lower blood pressure.
