Correct Answer: A

Rationale: In the evaluation phase of the nursing process, the nurse sets priorities for patient care to determine the effectiveness of nursing interventions. This involves comparing achieved outcomes with established goals. Choices B and D are related to evaluation as they involve determining whether outcomes or standards are met and documenting results of goal achievement, respectively. However, choice C, ambulating the patient, is an intervention that would typically occur in the implementation phase, not the evaluation phase. Therefore, the correct answer is A because setting priorities for patient care is a key component of the evaluation phase.

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.

Correct Answer: D

Rationale: The correct answer is D because sickle cell disease is an autosomal recessive genetic disorder. The disease is caused by inheriting two copies of the abnormal hemoglobin gene (HbS). In choice D, the father is HbA (normal) and the mother is HbS (carrier). This combination ensures that the child will inherit one normal gene and one abnormal gene, making them a carrier like the mother but not affected by the disease. Choices A, B, and C all involve at least one parent who carries the HbS gene, increasing the risk of the child having sickle cell disease.

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: A

Rationale: The correct answer is A: Age-related changes. Older clients are more susceptible to immune system disorders due to age-related changes such as a weakened immune response, increased inflammation, and decreased production of immune cells. Providing special care is important to address these specific vulnerabilities. Incorrect choices: B: Use of multiple drugs (Polypharmacy) - While polypharmacy can impact the immune system, it is not the primary factor for providing special care to older clients with immune system disorders. C: Poor diet - While diet plays a role in overall health, it is not the main factor necessitating special care for older clients with immune system disorders. D: Reduced activity levels - Although physical activity is important for overall health, reduced activity levels are not the primary reason for providing special care to older clients with immune system disorders.
