1. Which systolic blood pressure measurement is classified as prehypertension?

• A. 106 mmHg
• B. 119 mmHg
• C. 130 mmHg
• D. 141 mmHg

Correct answer: B

Rationale: According to the blood pressure classification, a systolic blood pressure between 120-139 mmHg is considered prehypertension. This range indicates an increased risk for developing hypertension if not managed appropriately. Therefore, a systolic blood pressure of 119 mmHg falls into the prehypertension category. A systolic pressure of 106 mmHg is within the normal range, while 130 mmHg and above would be classified as stage 1 and stage 2 hypertension respectively, not prehypertension.

2. Which food is recommended for someone with lactose intolerance?

• A. Skim milk
• B. Cheese
• C. Lactose-free yogurt
• D. Whole milk

Correct answer: C

Rationale: Lactose-free yogurt is suitable for individuals with lactose intolerance as it has reduced lactose content.

3. Muscle weakness due to wasting would most likely be evaluated by which test?

• A. recall of food intake
• B. skinfold thickness
• C. handgrip strength
• D. red blood cell levels

Correct answer: C

Rationale: Handgrip strength is a reliable test to assess muscle function and detect muscle weakness due to wasting. It is often used to identify conditions like sarcopenia in clinical settings. Options A, B, and D are not suitable for evaluating muscle weakness. Food intake recall does not directly measure muscle function, skinfold thickness assesses body fat but not muscle strength, and red blood cell levels are unrelated to muscle wasting.

4. Name 4 of the 12 discussed groups at risk for nutritional deficiencies.

• A. Elderly
• B. Low income
• C. Vegans
• D. Chronic disease, alcoholics

Correct answer: A

Rationale: The correct answer is A: Elderly. The other choices provided, low income, vegans, and chronic disease, alcoholics, are also at risk for nutritional deficiencies but the question specifically asks for 4 groups out of the 12 discussed. The 12 groups at risk for nutritional deficiencies include the elderly, low income individuals, vegans, chronic disease, alcoholics, smokers, periods of growth, individuals with medical conditions, physical stress, physiological stress, those on polypharmacy, and those with inadequate intake. The question focuses on identifying 4 out of these 12 groups, making 'Elderly' the correct choice.

5. What physiological role does phosphorus 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: D

Rationale: The correct answer is D. Phosphorus plays a crucial role in ATP energy release, the metabolism of fats, carbohydrates, and proteins, and regulation of acid-base balance. Choices A, B, and C are incorrect. Phosphorus is not directly involved in blood clotting, transmission of nerve impulses, muscle contraction, or calcium homeostasis. It also has known metabolic functions and is not associated with caries prevention.
