1. Low levels of high-density lipoproteins (HDL) are?

• A. associated with being underweight
• B. more prevalent in males
• C. highly predictive of CHD risk
• D. not a good predictor of CHD risk

Correct answer: C

Rationale: Low levels of HDL cholesterol are a strong predictor of coronary heart disease (CHD) risk because HDL helps to remove excess cholesterol from the bloodstream. Choice A is incorrect because low HDL levels are not associated with being underweight but rather with increased CHD risk. Choice B is incorrect as low HDL levels are not more prevalent in males but can affect both genders. Choice D is incorrect as low levels of HDL are indeed a good predictor of CHD risk.

2. A nurse is teaching a client about complete and incomplete proteins. Which of the following foods should the nurse include in the teaching as an incomplete protein?

• A. 4 oz chickpeas
• B. 2 poached eggs
• C. 2 oz cheddar cheese
• D. 4 oz salmon fillet

Correct answer: A

Rationale: The correct answer is A: 4 oz chickpeas. Chickpeas are considered an incomplete protein because they lack one or more essential amino acids required by the body. Incomplete proteins do not provide all essential amino acids in sufficient quantities. Choice B, 2 poached eggs, is a complete protein source because eggs contain all essential amino acids. Choice C, 2 oz cheddar cheese, is also a complete protein as it contains all essential amino acids. Choice D, 4 oz salmon fillet, is another complete protein source as fish typically provide all essential amino acids needed by the body.

3. Which of the following proteins is iron a component of, responsible for the transport of oxygen in the bloodstream?

• A. hemoglobin
• B. transferrin
• C. myoglobin
• D. hepcidin

Correct answer: A

Rationale: The correct answer is A: hemoglobin. Hemoglobin is the protein found in red blood cells that is responsible for carrying oxygen from the lungs to the rest of the body. Iron is a crucial component of hemoglobin, binding to oxygen and allowing for its transport. Choice B, transferrin, is involved in iron transport in the blood but not in oxygen transport. Choice C, myoglobin, is a protein found in muscle cells that stores oxygen for muscle use, not transportation in the bloodstream. Choice D, hepcidin, is a peptide hormone that regulates iron absorption in the intestines and iron distribution in the body, but it is not directly involved in oxygen transport.

4. Metabolic control is especially important for women with gestational diabetes to ensure the infant does not develop:

• A. microsomia
• B. macrosomia
• C. type 1 diabetes
• D. type 2 diabetes

Correct answer: B

Rationale: Metabolic control is crucial for women with gestational diabetes to prevent the development of macrosomia, which is characterized by an abnormally large baby. This condition poses risks such as birth injuries and necessitates careful management of blood sugar levels. Microsomia is not a known term related to this context. Type 1 and type 2 diabetes are not conditions the infant would develop as a result of gestational diabetes in the mother.

5. Patients with congestive heart failure need to restrict their intake of:

• A. fiber
• B. sodium
• C. cholesterol
• D. saturated fat

Correct answer: B

Rationale: Patients with congestive heart failure need to restrict their intake of sodium. This restriction is crucial to prevent fluid retention, which can exacerbate the condition. While fiber is generally beneficial for heart health, sodium restriction is more critical in this scenario. Cholesterol and saturated fat intake should also be monitored, but sodium restriction takes precedence due to its direct impact on fluid balance.
