LPN Pharmacology Assessment A

Correct Answer: C

Rationale: When a client with heart failure is prescribed furosemide, the nurse should monitor for hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss, which increases the risk of hypokalemia. Hypokalemia can have serious implications such as cardiac dysrhythmias. Therefore, it is essential to closely monitor the client's serum potassium levels while on furosemide to prevent complications.

Correct Answer: B

Rationale: The correct answer is to inform the client to expect red-orange discoloration of body fluids when taking rifampin. This side effect is harmless but can be surprising to patients. It is important for the nurse to educate the client about this expected change to prevent unnecessary concern or alarm. Monitoring for hyperglycemia is not directly related to rifampin, and taking the medication with food or avoiding dairy products are not specific instructions for this medication.

Correct Answer: A

Rationale: Shortness of breath and frothy sputum are indicative of pulmonary edema, a serious condition that requires immediate intervention to improve oxygenation. Administering oxygen is the priority action to support the client's respiratory function and prevent further deterioration. Oxygen therapy helps increase the oxygen levels in the blood, alleviate respiratory distress, and support vital organ function. Prompt intervention with oxygen can help stabilize the client while further assessments and treatments are initiated.

Correct Answer: B

Rationale: It is essential to rotate the application site of the nitroglycerin patch to prevent skin irritation and ensure consistent absorption of the medication. Applying it to the same site can lead to skin irritation and decreased effectiveness.

Correct Answer: A

Rationale: Taking aspirin with food is recommended to prevent gastrointestinal irritation and upset, which are common side effects of aspirin. It helps to protect the stomach lining and reduce the risk of developing ulcers. This instruction is crucial in promoting medication adherence and minimizing discomfort for the patient.
