- A. WBC
- B. PT and PTT
- C. Electrolytes
- D. BUN
Correct Answer: A
Rationale: Chemotherapy suppresses bone marrow, slashing white blood cell counts especially neutrophils heightening infection risk, making WBC monitoring paramount. Low counts trigger protective measures or treatment holds, directly tied to therapy's myelosuppressive core. PT and PTT track clotting, relevant for bleeding but less immediate. Electrolytes matter for overall status, but imbalances aren't chemotherapy's primary threat. BUN reflects kidney function, indirectly affected by some drugs, not the frontline concern. WBC's critical drop demands swift action fevers in neutropenia are emergencies underscoring its priority in safeguarding patients through treatment's immune-compromising phases.

A nurse in the oncology clinic is providing preoperative education to a client just diagnosed with cancer. The client has been scheduled for surgery in 3 days. What action by the nurse is best?
- A. Call the client at home the next day to review teaching.
- B. Give the client information about a cancer support group.
- C. Provide all the preoperative instructions in writing.
- D. Reassure the client that surgery will be over soon.
Correct Answer: A
Rationale: A new cancer diagnosis combined with the urgency of surgery in three days can overwhelm a client, impairing their ability to process and retain preoperative instructions due to emotional stress and anxiety. Calling the client the next day to review teaching allows the nurse to reinforce key points, answer questions, and ensure comprehension when the client may be calmer and more receptive. While providing written instructions is helpful, it assumes literacy and may not address immediate confusion or emotional barriers. Offering support group information is valuable for long-term coping but doesn't prioritize the urgent need for surgical preparation. Reassuring the client that surgery will be over soon dismisses their concerns and doesn't enhance understanding. The follow-up call is the best action, as it aligns with adult learning principles and nursing's role in ensuring informed consent and readiness, reducing perioperative risks and anxiety for the client.
