1. What should the nurse emphasize regarding the risks associated with hormone replacement therapy (HRT) in a patient with a history of cardiovascular disease?
- A. HRT is associated with an increased risk of cardiovascular events, including heart attack and stroke.
- B. HRT may decrease the risk of osteoporosis.
- C. HRT may improve mood and energy levels.
- D. HRT may increase the risk of venous thromboembolism.
Correct answer: A
Rationale: The correct answer is A because hormone replacement therapy (HRT) is associated with an increased risk of cardiovascular events, including heart attack and stroke, particularly in patients with a history of cardiovascular disease. Choice B is incorrect because HRT does not decrease the risk of osteoporosis; instead, it may have adverse effects on bone health. Choice C is incorrect as the improvement in mood and energy levels is not a significant risk associated with HRT. Choice D is incorrect because while HRT may increase the risk of venous thromboembolism, the question specifically focuses on patients with a history of cardiovascular disease, where the emphasis should be on cardiovascular risks.
2. What is a characteristic of coronary artery disease (CAD)?
- A. The build-up of infectious by-products in the lymph nodes
- B. Insufficient delivery of oxygenated blood to the myocardium
- C. Insufficient delivery of carbon dioxide to the lungs
- D. The build-up of bile in the stomach and gallbladder
Correct answer: B
Rationale: The correct characteristic of coronary artery disease (CAD) is the insufficient delivery of oxygenated blood to the myocardium. CAD is a condition where the coronary arteries become narrowed or blocked, leading to reduced blood flow to the heart muscle. This lack of oxygenated blood can result in chest pain, known as angina, and if a coronary artery becomes completely blocked, it can cause a heart attack. Choices A, C, and D are incorrect. Choice A refers to an issue related to the lymphatic system, choice C is about gas exchange in the lungs, and choice D describes a problem with bile accumulation in the digestive system, none of which are characteristics of CAD.
3. When educating a patient starting on oral contraceptives, what should the nurse include in the teaching plan regarding potential side effects?
- A. Weight gain, mood changes, and nausea
- B. Increased appetite, insomnia, and fatigue
- C. Breast tenderness, headaches, and dizziness
- D. Fatigue, hair loss, and joint pain
Correct answer: A
Rationale: The correct answer is A: Weight gain, mood changes, and nausea are common side effects of oral contraceptives. Weight gain may occur due to fluid retention or changes in metabolism. Mood changes can be caused by hormonal fluctuations. Nausea is a common side effect that usually improves after a few months of use. Choices B, C, and D are incorrect because they do not reflect common side effects associated with oral contraceptives. Increased appetite, insomnia, breast tenderness, headaches, dizziness, fatigue, hair loss, and joint pain are not typically reported side effects of oral contraceptives.
4. How are antibodies produced?
- A. B cells
- B. T cells
- C. Helper cells
- D. Memory cells
Correct answer: A
Rationale: Antibodies are produced by B cells. B cells are specialized white blood cells that generate antibodies as part of the immune response. B cells differentiate into plasma cells that secrete antibodies. T cells play a role in cell-mediated immunity, not antibody production. Helper cells, or helper T cells, assist in activating B cells but do not directly produce antibodies. Memory cells store information about previous infections but do not actively produce antibodies.
5. When arterial blood pressure declines, the kidneys secrete a hormone to increase blood pressure and peripheral resistance. What is this hormone called?
- A. Renin
- B. Antidiuretic hormone
- C. Atrial natriuretic
- D. Insulin
Correct answer: A
Rationale: Renin is the correct answer. When arterial blood pressure decreases, the kidneys release renin, which triggers a series of reactions ultimately leading to an increase in blood pressure and peripheral resistance. Antidiuretic hormone (choice B) is involved in water retention, atrial natriuretic hormone (choice C) promotes sodium excretion and lowers blood pressure, and insulin (choice D) regulates glucose metabolism, not blood pressure.
