Nursing Elites

1. Which mineral is a principal component of cell membranes?

• A. phosphorus
• B. magnesium
• C. iron
• D. iodine

Correct answer: A

Rationale: Phosphorus is the correct answer. It is a key component of cell membranes, being part of the phospholipid bilayer that provides structure and controls the movement of substances in and out of cells. Magnesium, iron, and iodine do not serve as principal components of cell membranes. Magnesium is involved in various enzymatic reactions, iron is essential for oxygen transport, and iodine plays a role in thyroid hormone synthesis.

2. A nurse is teaching a client about strategies to prevent constipation. Which of the following statements by the client indicates an understanding of the teaching?

• A. Drinking four to five glasses of water per day will prevent constipation.
• B. I should consume mineral oil once per day.
• C. Eating foods high in fiber will make elimination easier.
• D. I can skip a meal if I feel bloated.

Correct answer: C

Rationale: The correct answer is C. Eating foods high in fiber increases stool bulk and promotes easier elimination, thus preventing constipation. Choices A, B, and D are incorrect. Drinking water is important, but the emphasis should be on high-fiber foods. Mineral oil is not a recommended first-line treatment for constipation, and skipping meals can disrupt regular bowel movements, potentially leading to constipation.

3. Protein-energy malnutrition (PEM) may be responsible for the increased incidence of noma and necrotizing ulcerative gingivitis (NUG) because these conditions are associated with depressed immune responses caused by nutritional deficiencies.

• A. Both the statement and the reason are correct and related
• B. Both the statement and the reason are correct but are not related
• C. The statement is correct, but the reason is not correct
• D. The statement is not correct, but the reason is correct

Correct answer: A

Rationale: The corrected question highlights that protein-energy malnutrition weakens the immune system, making individuals more susceptible to conditions like noma and NUG, which are linked to compromised immunity. Choice A is correct because the statement and reason are both accurate and directly related. Protein-energy malnutrition does result in depressed immune responses, which can predispose individuals to noma and NUG. Choice B is incorrect because the statement and reason are indeed related. Choice C is incorrect as both the statement and reason are accurate. Choice D is also incorrect as the statement is correct and directly supports the reason provided.

4. Which animal-derived food contains the most significant level of carbohydrates?

• A. Egg
• B. Beef
• C. Milk
• D. Poultry

Correct answer: C

Rationale: Milk contains the most significant level of carbohydrates among animal-derived foods. Milk and milk products supply significant quantities of carbohydrate in the form of lactose. Eggs, beef, and poultry are not significant sources of carbohydrates compared to milk. In cheese making, lactose is removed as a by-product, reducing the carbohydrate content further.

5. Salome was fitted a hearing aid. She understood the proper use and wear of this device when she says that the battery should be functional, the device is turned on and adjusted to a:

• A. therapeutic level
• B. comfortable level
