1. Which of the following body processes is not dependent upon the presence of calcium in the body fluids?

• A. blood clotting
• B. transport of oxygen in the blood
• C. muscle contractions
• D. transmission of nerve impulses

Correct answer: B

Rationale: The transport of oxygen in the blood is carried out by hemoglobin, which does not require calcium; instead, calcium is essential for blood clotting, muscle contraction, and nerve transmission.

2. What dietary factor raises triglyceride levels?

• A. high refined carbohydrate intake
• B. low soluble fiber intake
• C. high iron intake
• D. low fat intake

Correct answer: A

Rationale: The correct answer is A: high refined carbohydrate intake. High intake of refined carbohydrates, such as sugars and white flour, can lead to elevated triglyceride levels, increasing the risk of cardiovascular disease. Choice B, low soluble fiber intake, is incorrect because soluble fiber actually helps lower triglyceride levels. Choice C, high iron intake, is incorrect as iron intake is not directly linked to raising triglyceride levels. Choice D, low fat intake, is also incorrect as not all fats raise triglyceride levels; it depends on the type of fat consumed.

3. A nurse is assessing a client who reports muscle spasms in his calves and tingling in his hands. The client indicates consuming a low intake of milk products and green leafy vegetables. The nurse should identify that the client's findings indicate a deficiency in which of the following sources of nutrition?

• A. Iron
• B. Omega-3 fatty acids
• C. Vitamin C
• D. Calcium

Correct answer: D

Rationale: The correct answer is D, Calcium. Muscle spasms and tingling suggest a calcium deficiency, which is commonly associated with a low intake of milk products and green leafy vegetables. Iron (choice A) deficiency typically presents with fatigue and weakness, not muscle spasms and tingling. Omega-3 fatty acids (choice B) are essential for brain function and heart health, but their deficiency does not manifest as muscle spasms and tingling. Vitamin C (choice C) deficiency leads to scurvy with symptoms like bleeding gums and bruising, not muscle spasms and tingling.

4. When counseling a teenager about fast food, a dental hygienist could correctly cite which of the following facts, with one exception. Which is the exception?

• A. Most fast food menus lack a rich source of vitamin A
• B. Consumer demands have driven the establishment of salads and other healthy menu items
• C. Shortages of biotin, folate, pantothenic acid, and copper are reported in fast foods
• D. Studies reveal that protein is lacking in most menu items

Correct answer: D

Rationale: The correct answer is 'D'. Fast food is generally not deficient in protein since it often contains meat, a significant source of protein. On the other hand, fast food is known to lack essential nutrients like Vitamin A and certain minerals, as mentioned in choices 'A' and 'C'. Choice 'B' is also accurate as many fast food establishments have started offering healthier options such as salads due to customer demands. Therefore, all options are true except 'D', which makes it the exception.

5. What primarily determines the Dietary Reference Intake (DRI) for protein?

• A. Intake of fatty acids
• B. Gender
• C. Height
• D. Body weight

Correct answer: D

Rationale: The Dietary Reference Intake (DRI) for protein is primarily determined by an individual's body weight. This is because the body's protein requirement is proportionate to its size, which is generally reflected in the body weight. Therefore, choice D is correct. Choices A, B, and C are incorrect: While factors such as fatty acid intake, gender, and height can influence an individual's overall nutritional needs, they do not directly determine the DRI for protein.
