1. Which type of lipid is solid at room temperature?

• A. Cholesterol
• B. Phospholipid
• C. Saturated fat
• D. Trans fat

Correct answer: C

Rationale: Saturated fats, such as those found in butter and lard, are typically solid at room temperature due to the lack of double bonds, which allows the fat molecules to pack closely together. Cholesterol (Choice A) is a steroid, not a fat, and while it's solid at room temperature, it doesn't fit the general category of 'lipid' in the context of this question. Phospholipids (Choice B) are a major component of all cell membranes and can be both solid and liquid at room temperature depending on their composition. Trans fats (Choice D) can also be solid or liquid at room temperature, but they are not typically referred to as 'lipids' in a general sense.

2. All of the following are seen in a child with measles. Which one is not?

• A. Reddened eyes
• B. Coryza
• C. Pustule
• D. Cough

Correct answer: C

Rationale: Measles typically presents with symptoms like reddened eyes, coryza (inflammation of the mucous membrane in the nose), and cough. However, pustules are not a common symptom of measles. Pustules are more characteristic of conditions like chickenpox rather than measles. Understanding these distinctions is crucial for accurate diagnosis and appropriate treatment.

3. Macronutrients include each of the following except one. Which one is the exception?

• A. Fat
• B. Polyunsaturated fatty acids
• C. Carbohydrate
• D. Protein

Correct answer: D

Rationale: Macronutrients are nutrients required by the body in large amounts to provide energy and include carbohydrates, fats, and proteins. While protein is essential for the body, it is not classified as a macronutrient. Proteins are made up of amino acids and serve various functions in the body, such as building and repairing tissues, but they are not a direct energy source like carbohydrates and fats. Therefore, protein is the exception among the listed options, making it the correct answer. Choice A, Fat, Choice B, Polyunsaturated fatty acids, and Choice C, Carbohydrate, are all examples of macronutrients that provide energy and support various bodily functions.

4. The dietary guidelines for Americans recommend consuming:

• A. nutrient dense foods
• B. non-essential amino acids
• C. energy dense foods
• D. organically grown foods

Correct answer: A

Rationale: The guidelines emphasize nutrient-dense foods that provide essential vitamins, minerals, and other nutrients without excessive calories, sugars, or unhealthy fats.

5. What should Mrs. Smith do to increase her HDL levels, as advised by the nurse?

• A. Monitor her blood glucose levels
• B. Quit smoking
• C. Control her blood pressure
• D. Take fish oil supplements

Correct answer: B

Rationale: The correct answer is 'Quit smoking.' Smoking has been shown to lower HDL (High-Density Lipoprotein) levels, and quitting can help to improve these levels. HDL is often referred to as 'good cholesterol' because it helps to remove other forms of cholesterol from the bloodstream, reducing the risk of heart disease. While monitoring blood glucose levels, controlling blood pressure, and taking fish oil supplements can contribute to overall health and wellbeing, they do not directly increase HDL levels in the same way that quitting smoking does. Therefore, quitting smoking is the most effective way for Mrs. Smith to increase her HDL levels as advised by the nurse.
