Correct Answer: D

Rationale: The correct answer is D: Maturates T cells. The thymus gland is crucial for the maturation of T cells, a type of white blood cell that plays a central role in the adaptive immune response. T cells mature in the thymus through a process of selection and education, where they learn to distinguish self from non-self antigens. This process is essential for the development of a functional immune system. Choices A, B, and C are incorrect because the thymus gland does not play a role in the maturation of B cells, platelets, or red blood cells, respectively.

Correct Answer: D

Rationale: The correct answer is D: Diarrhea. Antibiotics can disrupt the normal balance of gut bacteria, leading to diarrhea. This occurs due to the overgrowth of harmful bacteria in the intestines. Monitoring for diarrhea is crucial to prevent dehydration and further complications. Platelet dysfunction (A), stomatitis (B), and oliguria/dysuria (C) are not typically associated with the disruption of normal flora by antibiotics. These symptoms are more likely related to other conditions or side effects of medications, making them incorrect choices in this scenario.

Correct Answer: A

Rationale: The correct answer is A because a positive diagnosis for HIV infection is confirmed through laboratory testing, specifically the ELISA and Western blot tests. These tests detect the presence of HIV antibodies in the blood, providing definitive evidence of the infection. Choice B is incorrect as weight loss and fever are symptoms but not diagnostic criteria. Choice C is incorrect as opportunistic infections are a consequence of HIV, not the diagnostic criteria. Choice D is incomplete and irrelevant. In summary, the key to diagnosing HIV is through positive laboratory tests, not just based on symptoms or associated infections.

Correct Answer: B

Rationale: The correct answer is B because subjective data in a nursing assessment refers to information provided by the patient, such as feelings, perceptions, and symptoms. In this case, the client stating 'I feel nauseated' represents subjective data. This type of information cannot be measured or observed directly. A, C, and D are incorrect: A: Heart rate of 90 beats per minute is an objective measurement that can be directly observed. C: Blood pressure of 130/80 mmHg is also an objective measurement that can be directly observed. D: Skin appears flushed is an objective observation that can be directly seen.

Correct Answer: C

Rationale: The correct response is C: “Would you like to meet with your family and your physician about this matter?” Rationale: 1. Involving the family and physician ensures a collaborative decision-making process. 2. It respects the client's autonomy and involves them in the decision-making process. 3. It promotes open communication and support from loved ones. 4. It addresses the client's concerns about continuing treatment based on family wishes. Summary: A: Refers to psychological support, but the client's primary concern is medical treatment decisions. B: Involves religious support, which may not align with the client's beliefs or address the medical decision. D: Acknowledges the client's feelings but lacks a collaborative approach involving family and healthcare team.
