Correct Answer: C

Rationale: The correct answer is C: Human, T-cell lymphotrophic virus, as it is the causative agent for HIV/AIDS. This virus specifically targets and infects the body's T-cells, weakening the immune system. Trichomonas vaginalis, Treponema pallidum, and Chlamydia trachomatis are all different pathogens that do not cause HIV/AIDS. Trichomonas vaginalis is a protozoan parasite that causes trichomoniasis, Treponema pallidum causes syphilis, and Chlamydia trachomatis causes chlamydia. Therefore, the correct answer is C based on the specific viral agent responsible for HIV/AIDS.

Correct Answer: D

Rationale: Pulmonary edema causes an increase in pressure in the pulmonary circulation, leading to an alteration in afterload due to increased resistance. It also causes fluid accumulation in the pulmonary vessels, affecting preload. Additionally, the heart may compensate by increasing contractility. Therefore, all of the above choices are altered in pulmonary edema. The incorrect choices are A, B, and C individually as they only represent one aspect of the alterations seen in pulmonary edema, while the correct answer D encompasses all three factors affected in this condition.

Correct Answer: D

Rationale: The correct answer is D: Hypocalcemia. The parathyroid glands regulate calcium levels in the body. Without them, calcium levels will drop, leading to hypocalcemia. A: Hypomagnesemia is incorrect because magnesium levels are not directly regulated by the parathyroid glands. B: Hyperkalemia and C: Hypernatremia are incorrect as they are not typically associated with parathyroid gland removal. In summary, the removal of parathyroid glands would result in hypocalcemia due to the disruption of calcium regulation in the body.

Correct Answer: D

Rationale: The correct answer is D, "Eliminate background noise." This technique is essential for older patients as they may have age-related hearing impairments. By reducing background noise, the patient can better focus on the information being conveyed. Sitting in bright sunlight (A) may cause glare and make it difficult to read or see clearly. Speaking in a high tone (B) may be perceived as aggressive or patronizing. Using small, white-on-black printed materials (C) may be challenging for older patients with visual impairments. Thus, eliminating background noise is the most effective technique to improve learning in preoperative older patients.

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.
