Correct Answer: B

Rationale: Subjective data refers to information provided by the client based on their feelings, perceptions, or beliefs. Nausea is a symptom that the client experiences and reports subjectively. The client feels nauseous, which is not something directly measurable like blood pressure, heart rate, or respiratory rate. Therefore, nausea is the correct choice for subjective data. Blood pressure, heart rate, and respiratory rate are all objective data that can be measured and observed. Blood pressure, heart rate, and respiratory rate are all objective data that can be measured and observed.

Correct Answer: C

Rationale: The correct answer is C: Cooked vegetables. Cooking vegetables helps to kill harmful bacteria and parasites that may pose a risk of infection to an immunocompromised individual like a patient with HIV. Raw fruits (A) and raw vegetables (B) may carry pathogens that can be dangerous for someone with a weakened immune system. Caesar dressing (D) may contain raw eggs, which also pose a risk for infection. Therefore, choosing cooked vegetables is the safest option to reduce the risk of infection for the patient with HIV.

Correct Answer: C

Rationale: The correct answer is C because in the humoral immune response, B cells are stimulated by T helper cells or macrophages to differentiate into plasma cells that produce antibodies or memory cells. This process involves the production of specific antibodies that target the foreign antigen. Choice A is incorrect because B cells do not phagocytize antigens; instead, they produce antibodies. Choice B is incorrect because T cells do not turn into plasma cells. It is the B cells that differentiate into plasma cells in the humoral immune response. Choice D is incorrect because T cells do not produce antibodies. T cells are involved in cell-mediated immunity, not the humoral immune response.

Correct Answer: D

Rationale: The correct answer is D - Shallow breathing and increasing lethargy. This could indicate a potential complication such as respiratory distress or postoperative infection. Shallow breathing may suggest respiratory compromise, while increasing lethargy could be a sign of systemic infection or inadequate oxygenation. A: Abdominal pain is common postoperatively and can be managed with pain medication. B: Serous drainage from the incision is normal and expected in the early postoperative period. C: Hypoactive bowel sounds are common after abdominal surgery due to anesthesia and manipulation of the bowel; it typically resolves as the patient recovers. In summary, the other options are common postoperative findings, while shallow breathing and increasing lethargy are concerning signs that require immediate attention.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Dressing changes twice a day help maintain a clean wound environment, reducing the risk of infection. 2. Regular dressing changes promote proper wound healing by facilitating moisture balance and removal of dead tissue. 3. It is a direct intervention that addresses the patient's poor wound healing. 4. Teaching the patient about signs of infection (B) is important but does not directly address the wound healing process. 5. Instructing the family on dressing changes (C) is helpful but should not substitute direct patient care. 6. Refocusing the patient from body image changes (D) is not directly related to improving wound healing.
