Correct Answer: D

Rationale: The correct answer is D: Lymphocyte. Lymphocytes are a type of white blood cell that play a crucial role in adaptive immunity. They include T cells and B cells, which are responsible for recognizing and attacking specific pathogens. T cells help regulate the immune response and directly attack infected cells, while B cells produce antibodies to target pathogens. Neutrophils (A), monocytes (B), and basophils (C) are important for innate immunity, not adaptive immunity. Neutrophils are phagocytic cells that engulf and destroy pathogens, monocytes differentiate into macrophages to engulf pathogens, and basophils are involved in allergic reactions. Therefore, the correct answer is D because lymphocytes are key players in adaptive immunity.

Correct Answer: B

Rationale: The correct answer is B because turning the patient every 2 hours helps prevent pressure ulcers caused by shearing forces. This intervention redistributes pressure, improving blood flow to the skin, thus reducing the risk of skin breakdown. Administering pain medication (A) does not directly address the skin integrity issue. Monitoring vital signs (C) is important but does not address skin integrity. Keeping bed rails up (D) may actually increase the risk of shearing forces.

Correct Answer: D

Rationale: The correct answer is D: All of the above. Malignant melanoma, basal cell epithelioma, and squamous cell carcinoma are all forms of skin cancer associated with prolonged sun exposure. Melanoma is the deadliest form, originating in melanocytes; basal cell and squamous cell carcinomas are more common but less aggressive. All three types can develop due to cumulative UV radiation exposure. Therefore, all options are correct in this context.

Correct Answer: B

Rationale: The correct answer is B: Human papillomavirus (HPV). HPV is the virus that causes genital warts. It is transmitted through sexual contact and is the most common sexually transmitted infection. Cytomegalovirus (A) does not cause genital warts. Herpes simplex virus type II (C) causes genital herpes, not warts. Human immunodeficiency virus (D) causes AIDS and weakens the immune system but does not directly cause genital warts.

Correct Answer: A

Rationale: The correct answer is A: Hypocortisolism. After a transsphenoidal hypophysectomy, the pituitary gland is removed or partially removed, leading to decreased cortisol production. Signs of hypocortisolism include weakness, fatigue, hypotension, weight loss, and electrolyte imbalances. Hyperglycemia (B) is not typically associated with this procedure. Hypoglycemia (C) is not a common concern post-hypophysectomy. Hypercalcemia (D) is not directly related to pituitary gland removal. Therefore, assessing for hypocortisolism is crucial for early detection and management post-surgery.
