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 C
Explanation
A. While using the correct needle size is important for insulin administration, it is not the most critical aspect of discharge planning. The focus should be on managing blood glucose levels and recognizing when medical intervention is needed.
B. Monitoring the skin for dryness at the injection site is a good practice, but it is not the most urgent issue to address in discharge planning for a newly diagnosed diabetic client.
C. Consistently elevated blood glucose levels above 200 mg/dL may indicate poor control of diabetes and require prompt adjustments in treatment. Teaching the client to recognize and report hyperglycemia is essential to prevent complications such as diabetic ketoacidosis (DKA).
D. Eye exams are important for long-term diabetes management to monitor for diabetic retinopathy, but every 3 months is excessive. Annual eye exams are typically sufficient unless otherwise indicated by the healthcare provider.
Correct Answer is A
Explanation
A. The HPV vaccination is a form of primary prevention as it aims to prevent the initial occurrence of cervical cancer by protecting against the human papillomavirus, which is a major risk factor for this cancer.
B. BRCA1 and BRCA2 testing is a form of genetic testing used for risk assessment rather than prevention; it helps identify individuals at high risk for breast and ovarian cancers but does not prevent cancer itself.
C. Annual mammograms are a secondary prevention measure aimed at early detection of breast cancer rather than preventing the disease from occurring, as they help identify cancer in its early stages.
D. Rehabilitation exercises post-chemotherapy are supportive measures for patients undergoing treatment; they do not constitute primary prevention, which focuses on measures taken before cancer develops.
