Correct Answer: A

Rationale: Hyperaldosteronism can lead to increased potassium retention, which can be problematic for individuals with heart failure. Limiting intake of high potassium foods is crucial to prevent hyperkalemia, a condition that can worsen heart failure.
Therefore, advising the client to limit high potassium foods is essential in managing hyperaldosteronism in the setting of heart failure.

Correct Answer: A

Rationale: The correct answer is A: Rash. Lamotrigine can cause a rash, which may indicate a serious adverse effect like Stevens-Johnson syndrome. Monitoring for a rash is crucial in clients taking lamotrigine to promptly address any potential severe reactions.

Correct Answer: D

Rationale: Hypokalemia predisposes a client on digoxin to digoxin toxicity. Symptoms of digoxin toxicity include abdominal pain, anorexia, nausea, vomiting, visual disturbances, bradycardia, and atrioventricular (AV) dissociation.
Therefore, assessment of serum potassium levels and prompt correction of hypokalemia are crucial interventions for clients taking digoxin.

Correct Answer: B

Rationale: In this scenario, the nurse should contact the pharmacy to obtain the correct heparin formulation as the prescription calls for heparin 1,000 units IV STAT. Low molecular weight heparin is not the same as unfractionated heparin, and therefore, the nurse should not administer the available low molecular weight heparin without first obtaining the correct medication. Diluting the available heparin, calculating an equivalent dose, or changing the route of administration would not address the discrepancy between the prescribed heparin and the available low molecular weight heparin.

Correct Answer: A

Rationale: The correct answer is A: Dry cough. Lisinopril, an ACE inhibitor, is known to cause a persistent dry cough as a common side effect. Monitoring for this adverse effect is crucial because it may lead to non-adherence to the medication. Hyperkalemia (choice
B) is a potential side effect of potassium-sparing diuretics, not ACE inhibitors like lisinopril. Hypernatremia (choice
C) refers to elevated sodium levels and is not a common side effect of lisinopril. Hyponatremia (choice
D) is a condition characterized by low sodium levels and is not a typical side effect of lisinopril.
Therefore, the nurse should focus on assessing the client for a dry cough when taking lisinopril.
