1. A patient is diagnosed with ischemic heart disease. She is prescribed filgrastim (Neupogen). What effect will this medication provide in the treatment of ischemic heart disease?

Correct answer: C

Rationale: Filgrastim (Neupogen) is a medication that promotes the growth of white blood cells. In the context of ischemic heart disease, promoting angiogenesis, the formation of new blood vessels, can improve blood flow to the heart muscle, reducing ischemia and potentially improving cardiac function. Therefore, the correct answer is C. Choices A and B are incorrect because filgrastim does not directly affect platelet levels. Choice D is also incorrect as filgrastim does not prevent thrombus formation.

2. Which of the following is a characteristic of the human immunodeficiency virus (HIV), which causes AIDS?

Correct answer: B

Rationale: The correct answer is B. HIV is a retrovirus that infects T cells and leads to the gradual destruction of the immune system. Choice A is incorrect because HIV infects T cells primarily, not just B cells. Choice C is incorrect because HIV infection requires host cell receptors for entry. Choice D is incorrect because cell death after HIV infection is not immediate; instead, the virus gradually weakens the immune system over time.

3. What condition is a result of Polycythemia Vera, which involves excess red blood cells?

Correct answer: A

Rationale: Polycythemia Vera, characterized by excess red blood cells, can cause tissue ischemia and necrosis due to the increased blood viscosity. This condition restricts blood flow, leading to inadequate oxygen delivery to tissues and subsequent tissue damage. Choices B, C, and D are incorrect because they are not directly associated with the pathophysiology of Polycythemia Vera.

4. A patient with a history of cardiovascular disease is prescribed hormone replacement therapy (HRT). What should the nurse emphasize regarding the long-term risks associated with HRT?

Correct answer: A

Rationale: HRT is associated with an increased risk of cardiovascular events, including heart attack and stroke, particularly in patients with a history of cardiovascular disease.

5. Interpret the following arterial blood gas results: PH = 7.30; PaCO2 = 55 mmHg; HCO3 = 24 mEq/L

Correct answer: A

Rationale: The correct answer is A: Respiratory acidosis. In respiratory acidosis, there is an accumulation of CO2 in the blood, leading to a decrease in pH. The elevated PaCO2 of 55 mmHg in the given results indicates hypoventilation, causing respiratory acidosis. Choices B, C, and D are incorrect because the provided data does not show metabolic acidosis, respiratory alkalosis, or metabolic alkalosis.
