The nurse knows the rationale for combination chemotherapy is to:
limit episodes of anticipatory and delayed emesis
lessen the client's risk of developing neutropenia
decrease time intervals between remission
broaden range of cell kill while minimizing toxicities to the client
The Correct Answer is D
A. While limiting emesis is important in cancer treatment, combination chemotherapy primarily focuses on improving efficacy and minimizing toxicities, not specifically targeting nausea and vomiting episodes.
B. Combination chemotherapy can actually increase the risk of neutropenia due to the cumulative effects of multiple agents, as each may independently lower white blood cell counts.
C. Decreasing time intervals between remission is not a primary goal of combination chemotherapy; rather, it aims to achieve better overall treatment outcomes.
D. The main rationale for using combination chemotherapy is to broaden the range of cancer cell kill through different mechanisms of action while minimizing the side effects associated with higher doses of a single agent. This approach can improve treatment efficacy and reduce the likelihood of resistance.

Correct Answer is B
Explanation
A. Picking up the implant with gloved hands does not ensure safety and proper handling of a radioactive material, as gloves do not provide adequate protection against radiation exposure.
B. Using long-handled forceps to pick up the implant and placing it in a lead container is the correct action, as it minimizes radiation exposure to the nurse and ensures the safe containment of the radioactive source.
C. Calling for the rapid response team is unnecessary in this scenario; the situation requires immediate containment of the radioactive material rather than emergency medical intervention.
D. Calling the radiation oncologist is not the first action; while it is important to inform the physician afterward, the priority is to secure the radioactive implant properly to prevent exposure.
Correct Answer is C
Explanation
A. While administering a narcotic analgesic may be necessary for pain management, it does not address the immediate post-operative needs related to respiratory function and mobility.
B. Encouraging a low-fat diet is important after a cholecystectomy, but this can be addressed after ensuring the client's respiratory function and mobilization are stable.
C. Encouraging the use of the incentive spirometer is the priority intervention as it promotes lung expansion, reduces the risk of atelectasis, and improves oxygenation, which is crucial in the post-operative period.
D. While ambulating the client is important for recovery and preventing complications such as deep vein thrombosis, it should follow ensuring that the patient is able to effectively use the incentive spirometer to maintain respiratory function first.
