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. Increasing fiber intake is generally beneficial for digestive health but alone may not address the client's specific concern regarding colon cancer risk, making this advice too narrow.
B. Discussing family history and early screening options with a primary care provider is crucial, as it can lead to earlier detection and intervention, especially given the family history of colon cancer.
C. The CEA blood test is not routinely used for cancer screening; it is primarily used to monitor treatment response or recurrence, not for predicting the development of cancer.
D. Waiting until the age of 60 to be concerned about colon cancer is not advisable, especially with a family history; proactive discussions about screening should begin earlier based on risk factors.
Correct Answer is C
Explanation
A. Contributing to the medical diagnosis is a secondary goal for nursing care. The nurse's primary role is to ensure patient safety and prevent complications such as falls, which are more likely in patients with sensory and motor impairments.
B. While establishing a baseline for future comparison is important, it is not the most immediate concern. The nurse's priority is preventing falls and injury related to the impairment.
C. The priority in this case is to protect the client from falls or injury, as impaired motor and sensory function in the lower extremities increases the risk for accidents. Preventing injury will guide the development of the care plan, such as implementing fall precautions.
D. Anticipating other neurologic deficits is valuable but not the most urgent concern compared to protecting the client from the immediate risk of falls.
