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.

B. Administering naloxone is appropriate if there is suspicion of opioid overdose; however, the priority is to address the low oxygen saturation first with non-invasive measures.
C. Checking the temperature and applying warmed blankets may be important, but the immediate concern is the low oxygen saturation.
D. Encouraging the client to take deep breaths is the most appropriate immediate action to improve oxygen saturation levels and enhance ventilation, as the client is in a post-anesthesia state where respiratory depression can occur.
