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. Why are hospital patients at greater risk for drug-nutrient interactions than they used to be?

• A. Hospitalized patients are more acutely ill
• B. Hospital routines interfere with the correct timing of medications
• C. Drugs used today are more toxic and have more side effects
• D. Responsibility for monitoring this is shared by various members of the healthcare team

Correct answer: A

Rationale: The correct answer is A. Hospitalized patients are at greater risk for drug-nutrient interactions because they are more acutely ill, often having multiple conditions and treatments that increase the risk of such interactions. Choice B is incorrect as hospital routines interfering with medication timing are not directly related to drug-nutrient interactions. Choice C is incorrect as the toxicity and side effects of drugs do not necessarily relate to interactions with nutrients. Choice D is incorrect as shared responsibility for monitoring does not directly contribute to the increased risk of drug-nutrient interactions in hospitalized patients.

3. What is the best position to measure the leg circumference of a client with bipedal edema?

• A. Dorsal recumbent
• B. Sitting
• C. Standing
• D. Supine

Correct answer: A

Rationale: When measuring the leg circumference of a client with bipedal edema, the best position to ensure accurate and consistent measurements is the dorsal recumbent position. This position allows the legs to be comfortably positioned, with the individual lying on their back and legs extended. This facilitates accurate measurement of the circumference without the influence of gravity. Sitting and standing positions may not provide optimal conditions for accurate leg circumference measurements as they may not allow the legs to be fully extended. The supine position, although similar to dorsal recumbent, may not provide the same level of comfort and accuracy in leg circumference measurement for a client with bipedal edema.

4. The type of lipoprotein that carries cholesterol from tissues to the liver for excretion is:

• A. Very low-density lipoprotein
• B. Intermediate-density lipoprotein
• C. Low-density lipoprotein
• D. High-density lipoprotein

Correct answer: D

Rationale: The correct answer is D, High-density lipoprotein (HDL). HDL is known as the 'good' cholesterol and plays a crucial role in transporting cholesterol from tissues back to the liver for excretion. This process helps in reducing the buildup of cholesterol in the bloodstream, thus lowering the risk of heart diseases. Very low-density lipoprotein (Option A), Intermediate-density lipoprotein (Option B), and Low-density lipoprotein (Option C) are not responsible for carrying cholesterol back to the liver for excretion like HDL does. Instead, they are associated with different functions related to cholesterol transportation within the body.

5. What is a primary intervention for managing hyperphosphatemia?

• A. Increasing calcium intake
• B. Increasing phosphorus intake
• C. Decreasing calcium intake
• D. Administering phosphate binders

Correct answer: D

Rationale: Administering phosphate binders is a primary intervention for managing hyperphosphatemia. Phosphate binders work by binding phosphorus in the gut, preventing its absorption. Increasing calcium intake (Choice A) is not a primary intervention for hyperphosphatemia and can actually exacerbate the condition by potentially raising calcium levels. Increasing phosphorus intake (Choice B) is contraindicated in hyperphosphatemia. Decreasing calcium intake (Choice C) may help manage hypercalcemia but is not the primary intervention for hyperphosphatemia.
