1. Which of the following describes a process of heat loss involving the transfer of heat from one surface to another?

A. Radiation
B. Conduction
C. Convection
D. Evaporation

Correct answer: B

Rationale: Conduction is the process of heat transfer that occurs between objects or substances that are in direct contact with each other. In this process, heat is transferred from a hotter surface to a cooler surface through direct contact. This type of heat transfer does not involve the movement of the substances themselves, only the transfer of thermal energy. Choice A, Radiation, is the transfer of heat in the form of electromagnetic waves and does not require a medium. Choice C, Convection, involves the transfer of heat through the movement of fluids (liquids or gases) due to density differences. Choice D, Evaporation, is a cooling process that involves the transformation of a liquid into a gas, absorbing heat in the process.

2. Who is at higher risk for drug-nutrient interactions?

A. Infants
B. People with diabetes
C. Women of childbearing age
D. Older men and women

Correct answer: D

Rationale: Older men and women are at higher risk for drug-nutrient interactions due to factors such as polypharmacy and physiological changes. Polypharmacy, common in older adults, increases the likelihood of interactions between drugs and nutrients. Physiological changes that occur with aging can affect how drugs and nutrients are absorbed, distributed, metabolized, and excreted in the body. Infants, people with diabetes, and women of childbearing age are not typically considered high-risk groups for drug-nutrient interactions compared to older adults.

3. In patients with heart failure, which type of diet is most recommended?

A. High-sodium
B. Low-sodium
C. High-fat
D. Low-carbohydrate

Correct answer: B

Rationale: In patients with heart failure, a low-sodium diet is most recommended. This type of diet helps manage fluid retention by reducing the amount of sodium in the body. Excess sodium can lead to fluid accumulation, putting additional strain on the heart. High-sodium diets can exacerbate symptoms of heart failure by causing fluid retention and increasing blood pressure. High-fat and low-carbohydrate diets are not specifically recommended for heart failure patients and may not address the underlying issues related to fluid balance and heart function.

4. Which of the following is a nonmedical member of a unit who receives additional training in providing care beyond basic first aid procedures?

A. Area support squad leader
B. ATLS specialist
C. Tactical lifesaver
D. Combat lifesaver

Correct answer: D

Rationale: The correct answer is D, 'Combat lifesaver.' A Combat Lifesaver is a nonmedical member of a unit who is trained in advanced first aid procedures, providing care beyond basic first aid. Choice A, 'Area support squad leader,' does not specifically refer to someone trained in providing advanced care. Choice B, 'ATLS specialist,' refers to someone trained in Advanced Trauma Life Support (ATLS), which is beyond the scope of the question. Choice C, 'Tactical lifesaver,' is not a recognized term for the role described in the question.

5. Neomycin may decrease absorption of which nutrient?

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: Fat-soluble vitamins. Neomycin is known to interfere with the absorption of fat-soluble vitamins. This is because neomycin can disrupt the normal gut flora responsible for the absorption of these vitamins. Choices A, B, and D are incorrect because neomycin primarily affects the absorption of fat-soluble vitamins, not minerals, proteins, amino acids, or water-soluble vitamins.
