Correct Answer: B

Rationale: Furosemide is a loop diuretic that acts by inhibiting sodium and chloride reabsorption in the loop of Henle, leading to increased diuresis. By reducing fluid retention, furosemide helps decrease the workload on the heart in patients with chronic heart failure. This medication does not directly increase cardiac output, decrease heart rate, or lower blood pressure as its primary action.

Correct Answer: B

Rationale: Sevelamer (RenaGel) binds with phosphorus in foods and prevents its absorption. By taking RenaGel with meals, the binding of phosphorus helps to reduce the phosphorus load absorbed from food, thus aiding in the management of hyperphosphatemia in clients with ESRD.

Correct Answer: A

Rationale: The primary advantage of prescribing rivaroxaban over warfarin for a patient with a history of deep vein thrombosis (DVT) is that rivaroxaban does not require regular INR monitoring. This eliminates the need for frequent blood tests to adjust the dosage, making it more convenient for patients to manage their anticoagulant therapy.

Correct Answer: B

Rationale: The correct answer is B: Diminished cough effort. Clients with myasthenia gravis often experience muscle weakness, including respiratory muscles, which can lead to diminished cough effort. This weakness can result in ineffective airway clearance, putting the client at a high risk. Pain when coughing (choice A) is not directly related to the etiology of ineffective airway clearance in myasthenia gravis. While thick, dry secretions (choice C) and excessive inflammation (choice D) can contribute to airway clearance issues, the primary concern in myasthenia gravis is the muscle weakness affecting cough effort.

Correct Answer: C

Rationale: The client's statement that they should take ranitidine with meals indicates a need for further teaching. Ranitidine is typically taken at bedtime or before meals to be most effective in reducing stomach acid. Taking it with meals may not provide the optimal therapeutic effect.
