1. Magnesium's major functions in the body would be least likely to include which of the following?

• A. allowing muscles to relax after contraction
• B. assisting the operation of hundreds of enzymes
• C. synthesis of protein in the soft tissues
• D. regulation of body temperature

Correct answer: D

Rationale: Magnesium plays a key role in muscle relaxation, enzyme operation, and protein synthesis, but it is not directly involved in regulating body temperature.

2. A client who is in her second trimester of pregnancy should increase her caloric intake by how many calories during this trimester?

• A. 110 cal/day
• B. 225 cal/day
• C. 340 cal/day
• D. 450 cal/day

Correct answer: C

Rationale: During the second trimester of pregnancy, it is recommended that a client increases their caloric intake by around 340 calories per day to support the growing needs of both the mother and the developing fetus. This additional intake helps ensure the proper nutrition and energy levels required during this crucial stage of pregnancy. Option A (110 cal/day) is too low to meet the increased demands. Option B (225 cal/day) is also below the recommended amount. Option D (450 cal/day) is higher than necessary and could lead to excessive weight gain, which is not ideal during pregnancy.

3. Sam is trying to lose weight by skipping lunch. By the middle of the afternoon, Sam is very uncomfortable and feels that they "have" to eat. Sam is experiencing:

• A. appetite
• B. satiety
• C. satiation
• D. hunger

Correct answer: D

Rationale: Hunger is the physiological need to eat, which Sam is experiencing due to skipping a meal and the body signaling the need for nutrients.

4. Which of the following is a factor that affects Basal Metabolic Rate (BMR)?

• A. Age
• B. Sleep
• C. Fasting/Starvation
• D. All of the above

Correct answer: D

Rationale: All the listed options (Age, Sleep, Fasting/Starvation, Activity Level) are factors that can affect a person's Basal Metabolic Rate (BMR). BMR is the number of calories your body needs to accomplish its most basic (basal) life-sustaining functions. Age can affect BMR as metabolism slows with age. Sleep can influence BMR as metabolism slows during sleep. Fasting or starvation can decrease BMR as the body conserves energy. Activity level can also influence BMR; the more active you are, the higher your BMR, as your body requires more energy for physical activities.

5. Each of the following is a characteristic of fat, except one. Which is the exception?

• A. 95% of ingested fats are absorbed
• B. Hard fats take longer to digest than soft fats
• C. Fats contribute to palatability and flavor of foods
• D. Cooked fats improve the texture of foods

Correct answer: B

Rationale: The correct answer is B. Hard fats take longer to digest than soft fats because hard fats are solid at body temperature, making them more challenging to break down. Choice A is true as the majority of ingested fats are absorbed. Choice C is correct as fats indeed contribute to the palatability and flavor of foods. Choice D is accurate as cooked fats can enhance the texture of foods.
