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?

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.

A) This choice is incorrect because taking digoxin with a high-fat meal is not necessary. Digoxin can be taken with or without food, but consistent administration is essential for optimal therapeutic effects.

B) This choice is incorrect because skipping a dose of digoxin can lead to suboptimal medication levels and reduced effectiveness. If the client experiences nausea or vomiting, they should contact their healthcare provider for guidance.

C) This choice is correct. Digoxin is used to treat congestive heart failure and other cardiac conditions. It is crucial for clients to monitor their blood pressure regularly, especially if their healthcare provider has instructed them to adjust the medication dose based on their blood pressure readings.

D) This choice is incorrect because while avoiding certain over-the-counter medications is essential while on digoxin due to potential drug interactions, it is not the primary instruction for the client. The client should discuss any new medications, including over-the-counter drugs, with their healthcare provider to ensure they are safe to take with digoxin.
