1. What physiologic role does magnesium play in the body?

• A. Blood clotting, transmission of nerve impulses, muscle contraction and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance

Correct answer: B

Rationale: The correct answer is B. Magnesium plays an important role in maintaining calcium homeostasis and preventing skeletal abnormalities. It is involved in more than 300 enzymatic reactions, including energy metabolism, insulin activity, and glucose use. Magnesium is vital to the structural integrity of heart muscle and other muscles and nerves. While magnesium does play a role in blood clotting, nerve impulses, muscle contraction, relaxation, ATP energy release, and metabolism of fats, carbohydrates, proteins, the primary physiologic role of magnesium in the body is related to calcium homeostasis and maintaining the structural integrity of the heart muscle. Choice A is incorrect because it includes functions of magnesium, but they are not its primary physiologic role. Choice C is incorrect as magnesium has several known metabolic functions. Choice D is incorrect because although magnesium is involved in ATP energy release and metabolism, its primary role is related to calcium homeostasis and structural integrity of muscle.

2. One of the following statements is true with regards to the care of clients with depression:

• A. Only mentally ill persons commit suicide
• B. All depressed clients are considered potentially suicidal
• C. Most suicidal person gives no warning
• D. The chance of suicide lessens as depression lessens

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

3. 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.

4. A healthcare provider is admitting a client who practices Hinduism. The healthcare provider should identify that which of the following foods is prohibited according to Hindu dietary practices?

• A. Pork
• B. Chicken
• C. Beef
• D. Seafood

Correct answer: C

Rationale: In Hindu dietary practices, beef is prohibited due to religious beliefs. Hindus consider cows to be sacred animals, and therefore consuming beef is strictly forbidden. Pork, chicken, and seafood are not prohibited in Hindu dietary practices, making choices A, B, and D incorrect.

5. Match amylase with its digestive action:

• A. breaks down carbs
• B. breaks down proteins
• C. breaks down lipids
• D. helps fat digestion

Correct answer: A

Rationale: The correct answer is A: 'breaks down carbs.' Amylase is an enzyme that specifically targets carbohydrates, breaking them down into simpler sugars like maltose. This process aids in the digestion of carbohydrates in the human body. Choices B, C, and D are incorrect because amylase does not break down proteins, lipids, or directly aid fat digestion. Proteins are broken down by proteases, lipids are broken down by lipases, and fat digestion is primarily assisted by bile salts and lipases in the small intestine.
