A nurse is caring for a client with suspected congestive heart failure. Which blood test is specifically used to measure heart strain and assist in the diagnosis of CHF?
Complete blood count (CBC)
Basic metabolic panel (BMP)
Brain natriuretic peptide (BNP) level
C-reactive protein (CRP) level
The Correct Answer is C
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.

Correct Answer is C
Explanation
A) This choice is incorrect because ACE inhibitors should not be taken with grapefruit juice. Grapefruit juice can interfere with the metabolism of the medication, leading to increased levels and potential side effects.
B) This choice is incorrect because the client should not adjust the dose of the ACE inhibitor without consulting their healthcare provider. Blood pressure should be monitored, but any dosage adjustments should be made by the healthcare provider based on the client's response to the medication.
C) This choice is correct. ACE inhibitors can cause a side effect of a persistent dry cough, and in some cases, difficulty breathing. The client should promptly report these symptoms to their healthcare provider for evaluation and possible adjustment of the medication regimen.
D) This choice is incorrect because while ACE inhibitors can increase potassium levels, avoiding foods high in potassium is not necessary unless specifically directed by the healthcare provider. The client should follow a balanced diet and inform the healthcare provider of any changes in their dietary habits.
Correct Answer is D
Explanation
A) This choice is incorrect because while electrolyte imbalances can have cardiovascular implications, they are not directly associated with diabetes mellitus or congestive heart failure.
B) This choice is incorrect because left-sided heart failure is not directly related to uncontrolled diabetes mellitus. However, diabetes can exacerbate heart failure if not well-controlled due to its impact on blood vessels and the heart.
C) This choice is incorrect because decreased afterload is not directly related to uncontrolled diabetes mellitus. Afterload refers to the resistance the heart has to overcome to eject blood into the circulation.
D) This choice is correct. Uncontrolled diabetes mellitus can lead to microvascular damage, particularly in the small blood vessels of the heart. This damage can contribute to heart muscle dysfunction and congestive heart failure. Diabetes is a significant risk factor for developing heart failure.
