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

Answer and Explanation

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 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.

A. Lesion of cranial nerve IX B. Vestibular disease C. Dysfunction of the cerebellum D. Arteriovenous malformation (AVM) at frontal lobe

Correct Answer is C

Explanation

A. A lesion of cranial nerve IX primarily affects swallowing and taste sensations rather than motor coordination or balance, so this is unlikely to explain the patient's symptoms.
B. Vestibular disease typically results in vertigo and balance issues, but the specific observations of slow alternating movements and loss of balance during the Romberg Test suggest a different underlying cause.
C. Dysfunction of the cerebellum would explain the patient's difficulties with rapid alternating movements and balance issues, as the cerebellum is responsible for coordinating motor activity and maintaining posture and balance. This aligns with the assessment findings, indicating a probable cerebellar dysfunction.
D. While an AVM in the frontal lobe could affect motor control, the specific symptoms presented, such as the inability to perform rapid movements and balance issues, are more characteristic of cerebellar dysfunction rather than a frontal lobe lesion.
