Nursing Elites

1. Three major causes of atherosclerosis are:

• A. Hyperthyroidism, underweight, and poor appetite
• B. High blood cholesterol, high blood pressure, and cigarette smoking
• C. Constipation, peptic ulcer disease, and pancreatitis
• D. Kidney failure, edema, and sodium retention

Correct answer: B

Rationale: Atherosclerosis is primarily caused by high blood cholesterol, high blood pressure, and cigarette smoking. These factors contribute to the buildup of plaque in the arteries. Choices A, C, and D are incorrect. Hyperthyroidism, underweight, and poor appetite do not directly cause atherosclerosis. Similarly, constipation, peptic ulcer disease, pancreatitis, kidney failure, edema, and sodium retention are not among the primary causes of atherosclerosis.

2. The use of the antibiotic neomycin may decrease the absorption of:

• A. Iron, copper, and zinc
• B. Protein and amino acids
• C. Fat-soluble vitamins
• D. Water-soluble vitamins

Correct answer: C

Rationale: The correct answer is C. Neomycin can interfere with the absorption of fat-soluble vitamins such as vitamins A, D, E, and K. Choice A is incorrect because neomycin does not affect the absorption of iron, copper, and zinc. Choice B is incorrect as neomycin does not impact the absorption of protein and amino acids. Choice D is also incorrect as neomycin does not decrease the absorption of water-soluble vitamins like vitamin C and the B vitamins.

3. In patients receiving chemotherapy, which nutrient is often supplemented to manage mucositis?

• A. Vitamin E
• B. Vitamin B12
• C. Zinc
• D. Calcium

Correct answer: C

Rationale: Zinc supplementation is often used to manage mucositis in patients receiving chemotherapy. Zinc has been shown to aid in the healing process of mucositis. Vitamin E (Choice A) is not typically used to manage mucositis associated with chemotherapy. Vitamin B12 (Choice B) is essential for nerve function and the formation of red blood cells, but it is not primarily used to manage mucositis. Calcium (Choice D) is important for bone health and nerve function but is not specifically used to manage mucositis.

4. The nurse is aware that norepinephrine is secreted by which endocrine gland?

• A. The pancreas
• B. The adrenal cortex
• C. The adrenal medulla
• D. The anterior pituitary gland

Correct answer: C

Rationale: Norepinephrine is indeed secreted by the adrenal medulla, making choice C the correct answer. The adrenal medulla is part of the adrenal glands, located on top of the kidneys. Norepinephrine is involved in the body's 'fight or flight' response, helping to prepare the body to react to stress. Choices A, B, and D are incorrect as norepinephrine is not secreted by the pancreas, adrenal cortex, or the anterior pituitary gland.

5. The nurse is told in report that the client has aortic stenosis. Which anatomical position should the nurse auscultate to assess the murmur?

• A. Second intercostal space, right sternal border
• B. Erb’s point
• C. Second intercostal space, left sternal border
• D. Fourth intercostal space, left sternal border

Correct answer: A

Rationale: The correct answer is A: Second intercostal space, right sternal border. The aortic valve is best auscultated at the second intercostal space, right sternal border, where the murmur of aortic stenosis is heard most clearly. Choices B, C, and D are incorrect as they are not the recommended anatomical positions for auscultating the murmur of aortic stenosis.
