1. Macular degeneration occurs as a result of:

Correct answer: D

Rationale: Macular degeneration is a condition that affects the macula, a part of the retina responsible for central vision. It is primarily caused by impaired blood supply to the macula, leading to cellular waste accumulation and ischemia. This results in the death of photoreceptor cells and ultimately vision loss. Choices A, B, and C are incorrect because macular degeneration is not related to the loss of lens accommodation, detachment of the retina, or increased intraocular pressure. The correct answer directly addresses the underlying pathophysiology of macular degeneration.

2. A patient with a history of cardiovascular disease is being prescribed hormone replacement therapy (HRT). What should the nurse include in the patient education regarding the risks associated with HRT?

Correct answer: A

Rationale: The correct answer is A. Hormone replacement therapy (HRT) is associated with an increased risk of cardiovascular events, including heart attack and stroke, especially in patients with a history of cardiovascular disease. Choice B is incorrect because HRT does not decrease the risk of osteoporosis; in fact, it may increase the risk of certain conditions like venous thromboembolism, as mentioned in choice C. Choice D is also incorrect as HRT has been associated with a slight increase in the risk of breast cancer.

3. During a follow-up visit, a patient being treated for latent tuberculosis mentions inconsistent drug intake. What should subsequent health education focus on?

Correct answer: B

Rationale: The correct answer is B because consistent intake of prescribed drugs is crucial for curing tuberculosis. By emphasizing the necessity of following the treatment plan, the patient is more likely to achieve a successful outcome. Choice A is incorrect because it focuses on the risk of adverse effects rather than the primary goal of TB cure. Choice C is incorrect as it does not address the issue of inconsistent drug intake. Choice D is also incorrect as it introduces a different treatment (antiretrovirals) not relevant to latent tuberculosis.

4. A staff member asks what leukocytosis means. How should the nurse respond? Leukocytosis can be defined as:

Correct answer: B

Rationale: Leukocytosis refers to an abnormally high leukocyte count. This condition is characterized by an elevated number of white blood cells in the bloodstream. Choice A is incorrect because leukocytosis does not refer to a normal leukocyte count. Choice C is incorrect as leukocytosis is not related to a low leukocyte count. Choice D is incorrect as leukopenia is the opposite of leukocytosis, indicating a low white blood cell count.

5. An experiment is designed to determine specific cell types involved in cell-mediated immune response. The experimenter is interested in finding cells that attack cells that have specific antigens. Which cells should be isolated?

Correct answer: B

Rationale: Cytotoxic T cells are the key players in cell-mediated immunity as they directly attack cells displaying specific antigens. Lymphokine-producing cells (Choice A) are involved in cytokine production, while Helper T cells (Choice C) assist in activating other immune cells. Macrophages (Choice D) are phagocytic cells that engulf and digest pathogens, but they are not the primary cells responsible for directly attacking cells with specific antigens in cell-mediated immunity.
