Correct Answer: C

Rationale: The nurse should monitor the client for neutropenia when receiving capecitabine, as it is a common adverse effect caused by bone marrow suppression. Neutropenia increases the risk of infection, making it essential for the nurse to closely monitor the client's white blood cell count and assess for signs of infection during treatment.

Correct Answer: B

Rationale: The correct answer is to obtain help from another healthcare provider to confirm the correct client and blood product. This action is crucial in preventing an acute hemolytic reaction, which is caused by ABO or Rh incompatibility. Verifying the correct client and blood product before the transfusion ensures that there are no errors in identification, reducing the risk of a potentially life-threatening reaction.

Correct Answer: B

Rationale: Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can increase the risk of bleeding when taken with Warfarin due to its antiplatelet effects. Patients on Warfarin should avoid NSAIDs and opt for alternative pain relief options to prevent potential complications such as increased bleeding risk.

Correct Answer: A

Rationale: Losartan, an angiotensin II receptor blocker (ARB), can cause hyperkalemia by affecting the renin-angiotensin-aldosterone system. Monitoring serum potassium levels is crucial to detect and manage any potential hyperkalemia, which can lead to serious cardiac arrhythmias.

Correct Answer: B

Rationale: Atenolol is a beta-blocker that can cause bradycardia (slow heart rate). Monitoring the heart rate regularly is essential to detect any significant decreases promptly. This allows for timely intervention and adjustment of the medication regimen if needed, helping to prevent adverse effects associated with bradycardia.
