Nursing Elites

1. 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: The correct answer is C: The adrenal medulla. Norepinephrine is secreted by the adrenal medulla and is involved in the body's 'fight or flight' response. The pancreas (choice A) secretes insulin and glucagon, not norepinephrine. The adrenal cortex (choice B) secretes hormones like cortisol and aldosterone, but not norepinephrine. The anterior pituitary gland (choice D) secretes various hormones like growth hormone and thyroid-stimulating hormone, but not norepinephrine.

2. Which dietary change is most beneficial for a patient with hypertension?

• A. Increased sodium intake
• B. Decreased potassium intake
• C. Increased fiber intake
• D. Increased cholesterol intake

Correct answer: C

Rationale: The correct answer is C: Increased fiber intake. A diet high in fiber is beneficial for patients with hypertension as it helps lower blood pressure. Increasing fiber intake can aid in managing hypertension by promoting heart health and overall well-being. Choices A, B, and D are incorrect. Increased sodium intake is not recommended for hypertension as it can elevate blood pressure. Decreasing potassium intake is also not advised as potassium is essential for regulating blood pressure. Lastly, increasing cholesterol intake is detrimental for hypertension as it can contribute to cardiovascular issues and worsen the condition.

3. A client is transferred from the emergency department to the locked psychiatric unit after attempting suicide by taking 200 acetaminophen (Tylenol) tablets. The client is now awake and alert but refuses to speak with the nurse. In this situation, the nurse’s first priority is to:

• A. Establish a rapport to foster trust
• B. Place the client in full restraints
• C. Try to communicate with the client in writing
• D. Ensure safety by initiating suicide precautions

Correct answer: D

Rationale: In this scenario, the nurse's highest priority should be to ensure the client's safety by initiating suicide precautions. Given the history of a suicide attempt by taking a large number of acetaminophen tablets, there is a high risk of further self-harm. Placing the client in full restraints without assessing the situation properly may escalate anxiety and hinder therapeutic communication. Trying to communicate with the client in writing could be an option but ensuring immediate safety takes precedence. Establishing rapport is essential for building trust and therapeutic relationship, but safety concerns must be addressed first in this critical situation.

4. Warfarin (Coumadin) is an anticoagulant and interferes with the action of:

• A. Platelets
• B. Vitamin K
• C. Calcium
• D. Vitamin B12

Correct answer: B

Rationale: The correct answer is B: Vitamin K. Warfarin inhibits the action of vitamin K, which is essential for blood clotting. By interfering with the production of certain clotting factors, warfarin helps prevent blood clots. Choices A, C, and D are incorrect because warfarin primarily affects the vitamin K-dependent clotting factors and not platelets, calcium, or vitamin B12.

5. 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.
