A client with congestive heart failure presents with a dry, persistent cough. The nurse should recognize this symptom as:

A) This choice is correct. ACE inhibitors are used to lower blood pressure and reduce the workload on the heart. The client should monitor their blood pressure regularly and report any significant changes to their healthcare provider. Adjustments to the medication dosage should only be made under the guidance of the healthcare provider.

B) 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.

C) 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.

D) This choice is incorrect because limiting fluid intake is not specific to the administration of ACE inhibitors. Fluid intake may need to be adjusted based on the client's overall fluid balance and congestive heart failure status, but it is not a direct instruction related to the medication.

A) This choice is incorrect because hypernatremia (high sodium levels) is not a common adverse effect of loop diuretics. Loop diuretics primarily impact sodium and water excretion.

B) This choice is incorrect because hyperkalemia (high potassium levels) is not typically associated with loop diuretics. In fact, loop diuretics can lead to increased potassium excretion, potentially causing hypokalemia.

C) This choice is incorrect because hypocalcemia (low calcium levels) is not a common adverse effect of loop diuretics. Loop diuretics primarily affect sodium, potassium, and water excretion.

D) This choice is correct. Loop diuretics are potent potassium-wasting diuretics, meaning they increase potassium excretion in the urine, potentially causing hypokalemia. The nurse should closely monitor the client's potassium levels and provide potassium supplementation if necessary.
