Correct Answer: A

Rationale: Lanthanum carbonate is prescribed in chronic kidney disease to bind dietary phosphorus in the gastrointestinal tract. This action can lead to decreased phosphorus absorption and potential hypercalcemia due to the increased serum calcium levels.
Therefore, the nurse should monitor the client for signs and symptoms of hypercalcemia, such as confusion, fatigue, and muscle weakness.

Correct Answer: A

Rationale: The correct answer is A: Increased risk of infection. Infliximab is known to increase the risk of infection due to its immunosuppressive effects. It is crucial for the nurse to monitor for signs of infection in the client receiving infliximab to promptly address any potential complications and ensure the client's safety and well-being.

Correct Answer: B

Rationale: Hydrochlorothiazide is a diuretic that can lead to potassium loss, resulting in hypokalemia. Monitoring for hypokalemia is essential because it can cause various complications such as cardiac dysrhythmias.
Therefore, the practical nurse should closely watch for signs and symptoms of low potassium levels in clients taking hydrochlorothiazide.

Correct Answer: B

Rationale: The correct instruction for a client taking digoxin is not to take the medication if the heartbeat is irregular or slow. Digoxin can affect the heart rhythm, so it is crucial to monitor the pulse rate. In case of irregular or slow heartbeats, the medication should be withheld, and the healthcare provider should be consulted. This step is necessary to prevent potential complications associated with digoxin therapy.

Correct Answer: A

Rationale: The correct answer is A: Increased risk of bleeding. Edoxaban is an anticoagulant that works by inhibiting clot formation, thereby increasing the risk of bleeding.
Therefore, the nurse should closely monitor the client for signs of bleeding, such as bruising, petechiae, hematuria, or gastrointestinal bleeding, to prevent potential complications.
