Correct Answer: D

Rationale: Sentinel lymph node biopsy is a minimally invasive alternative to more extensive lymph node dissection. This procedure involves identifying and removing the first lymph node(s) to which a tumor drains, known as the sentinel node(s), to determine if cancer has spread beyond the primary site. Choices A, B, and C are incorrect because lymphadenectomy refers to the surgical removal of lymph nodes, needle biopsy involves sampling tissue with a needle for analysis, and open biopsy refers to the surgical removal of a sample of tissue for examination, none of which specifically serve as an alternative to lymph node dissection in this context.

Correct Answer: A

Rationale: Corrected Detailed Rationale: Yellow skin is a sign of jaundice, which is often associated with liver disease. Liver function tests (LFTs) help in evaluating liver health and function. A complete blood count (CBC) primarily assesses red and white blood cells and platelets, not directly related to jaundice. Platelet count specifically measures platelets in the blood and is unrelated to the yellow skin observed in this patient. Blood urea nitrogen and creatinine tests focus on kidney function, not typically associated with yellow skin, making them less relevant in this context.

Correct Answer: A

Rationale: The correct answer is A: Strict hand hygiene. Neutropenic clients have a low level of neutrophils, which are important in fighting infections. Therefore, maintaining strict hand hygiene is crucial in preventing the introduction of pathogens that could lead to infections. Limiting visitor contact (choice B) is important but not as critical as preventing the introduction of pathogens through proper hand hygiene. Administering prophylactic antibiotics (choice C) and blood products (choice D) are treatment measures and do not address the preventive aspect that hand hygiene provides.

Correct Answer: A

Rationale: The correct answer is A: Vital signs. Monitoring vital signs is crucial during the infusion of monoclonal antibody therapy as there is a risk of infusion reactions such as fevers, chills, hypotension, and tachycardia. Assessing vital signs allows for early detection of any adverse reactions, enabling prompt intervention. Skin reactions (choice B), respiratory status (choice C), and renal function (choice D) are important assessments in general patient care but are not the priority during the infusion of monoclonal antibody therapy.

Correct Answer: A

Rationale: The correct answer is A: Decreased immune function. Aging leads to a decline in immune function, which increases susceptibility to infections during chemotherapy. This decline is due to changes in the immune system that occur with age. Choices B, C, and D are incorrect because while they may impact overall health in older clients, they do not directly increase susceptibility to infections during chemotherapy like decreased immune function does.
