When displayed by the patient, which symptom would be most indicative to the nurse to withhold a recently prescribed nonselective beta-adrenergic blocker?

Hyperglycemia

Dizziness

Peripheral edema

Wheezing

Answer and Explanation

The Correct Answer is D

Choice A reason: This is not a symptom that would indicate withholding a nonselective beta-adrenergic blocker. Hyperglycemia is a high level of glucose in the blood, which can be caused by diabetes or other conditions. Nonselective beta-adrenergic blockers do not affect blood glucose levels directly, but they may mask the signs of hypoglycemia (low blood glucose) in diabetic patients.

Choice B reason: This is not a symptom that would indicate withholding a nonselective beta-adrenergic blocker. Dizziness is a common side effect of many medications, especially those that lower blood pressure. Nonselective beta-adrenergic blockers can cause dizziness by reducing the heart rate and cardiac output, but this is usually mild and transient.

Choice C reason: This is not a symptom that would indicate withholding a nonselective beta-adrenergic blocker. Peripheral edema is swelling of the ankles, feet, or legs, which can be caused by heart failure, kidney disease, or venous insufficiency. Nonselective beta-adrenergic blockers do not cause peripheral edema, but they may worsen it in patients with heart failure.

Choice D reason: This is a symptom that would indicate withholding a nonselective beta-adrenergic blocker. Wheezing is a high-pitched sound that occurs when breathing is obstructed, usually due to asthma or chronic obstructive pulmonary disease (COPD). Nonselective beta-adrenergic blockers can aggravate or cause wheezing by blocking the beta-2 receptors in the lungs, which normally cause bronchodilation (widening of the airways). Therefore, nonselective beta-adrenergic blockers are contraindicated in patients with asthma or COPD.

Correct Answer is D

Explanation

Choice A reason: This is not a sign of left-sided heart failure. Jugular vein distension is a sign of right-sided heart failure, which occurs when the right ventricle fails to pump blood effectively to the lungs.

Choice B reason: This is not a sign of left-sided heart failure. Increased blood pressure is a risk factor for developing heart failure, but it does not indicate the severity or location of the heart failure.

Choice C reason: This is not a sign of left-sided heart failure. Hepatomegaly is a sign of right-sided heart failure, which occurs when the right ventricle fails to pump blood effectively to the systemic circulation.

Choice D reason: This is a sign of left-sided heart failure. Decreased urine output is a result of reduced renal perfusion, which occurs when the left ventricle fails to pump blood effectively to the aorta and the rest of the body.

A. Insomnia B. Bradycardia C. Chest pain D. Hyperkalemia

Correct Answer is D

Explanation

Choice A reason: This is not an adverse effect of ACE inhibitors. Insomnia is a common side effect of stimulant medications, such as caffeine or amphetamine, which increase the activity of the central nervous system and cause difficulty falling or staying asleep.

Choice B reason: This is not an adverse effect of ACE inhibitors. Bradycardia is a slow heart rate, usually below 60 beats per minute. ACE inhibitors do not cause bradycardia, but rather lower the blood pressure by blocking the formation of angiotensin II, a potent vasoconstrictor.

Choice C reason: This is not an adverse effect of ACE inhibitors. Chest pain is a sign of angina or myocardial infarction, which are caused by reduced blood flow to the heart muscle. ACE inhibitors can actually prevent or treat these conditions by improving the blood flow and reducing the workload of the heart.

Choice D reason: This is an adverse effect of ACE inhibitors. Hyperkalemia is a high level of potassium in the blood, which can cause cardiac arrhythmias and muscle weakness. ACE inhibitors can cause hyperkalemia by reducing the secretion of aldosterone, a hormone that regulates the sodium and potassium balance in the body.
