A client with congestive heart failure is prescribed a beta-blocker. The nurse should closely monitor the client for which potential adverse effect of this medication?
Hypokalemia
Hypotension
Bradycardia
Hyperglycemia
The Correct Answer is C
A) This choice is incorrect because hypokalemia (low potassium levels) is more commonly associated with loop diuretics rather than beta-blockers.
B) This choice is incorrect because while hypotension (low blood pressure) can be a potential adverse effect of beta-blockers, it is not the primary adverse effect to be monitored for.
C) This choice is correct. Bradycardia (slow heart rate) is a common adverse effect of beta-blockers, which work by slowing the heart rate and reducing the force of the heart's contractions. The nurse should monitor the client's heart rate and report any significant changes or symptoms of bradycardia to the healthcare provider.
D) This choice is incorrect because hyperglycemia (high blood glucose levels) is not a common adverse effect of beta-blockers. In fact, beta-blockers can sometimes cause transient hypoglycemia.

Correct Answer is D
Explanation
A) This choice is incorrect because wheezing on auscultation is a characteristic finding in respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD), not congestive heart failure.
B) This choice is incorrect because hyperactive bowel sounds are not specific to congestive heart failure and are more indicative of gastrointestinal activity.
C) This choice is incorrect because the absence of jugular vein distention is not directly related to fluid accumulation in the lungs. Jugular vein distention is associated with right-sided heart failure.
D) This choice is correct. Crackles, also known as rales, are abnormal lung sounds heard on auscultation and may indicate fluid accumulation in the lungs, a common symptom of congestive heart failure. The presence of crackles suggests pulmonary congestion due to fluid leaking into the alveoli.
Correct Answer is C
Explanation
A) This choice is incorrect because a complete blood count (CBC) is a general blood test that measures different components of the blood, such as red blood cells, white blood cells, and platelets. It is not specifically used to measure heart strain or diagnose CHF.
B) This choice is incorrect because a basic metabolic panel (BMP) is a blood test that measures electrolytes, kidney function, and glucose levels. It is not specific to diagnosing CHF.
C) This choice is correct. A brain natriuretic peptide (BNP) level is a blood test specifically used to measure heart strain. Elevated BNP levels can indicate heart failure, making it a valuable diagnostic tool in assessing suspected CHF.
D) This choice is incorrect because a C-reactive protein (CRP) level is a marker of inflammation and is not specific to diagnosing CHF.
