1. Which vitamin is also known as Niacin?

• A. Vitamin B1
• B. Vitamin B2
• C. Vitamin B3
• D. Vitamin B12

Correct answer: C

Rationale: The correct answer is Vitamin B3, also known as Niacin. Niacin is essential for energy metabolism and can help improve cholesterol levels. Vitamin B1 is Thiamine, Vitamin B2 is Riboflavin, and Vitamin B12 is Cobalamin. These vitamins have different functions in the body and are not synonymous with Niacin.

2. A nurse is reinforcing teaching about food choices with the mother of an 8-month-old infant. Which of the following statements by the mother indicates a need for further teaching?

• A. I will give my child strained carrots and mashed egg yolks.
• B. I will give my child rice cereal and crackers.
• C. I will give my child pureed liver and strained pears.
• D. I will give my child applesauce and green peas.

Correct answer: B

Rationale: Choice B, 'I will give my child rice cereal and crackers,' indicates a need for further teaching. Infants should not be given crackers at 8 months of age due to the risk of choking. Rice cereal is appropriate for infants, but it should be introduced carefully to avoid digestive issues. Choices A, C, and D are appropriate food choices for an 8-month-old infant, providing a variety of nutrients and textures suitable for their age and developmental stage.

3. Which biomolecule is responsible for the storage and transfer of genetic information?

• A. Carbohydrates
• B. Proteins
• C. Lipids
• D. Nucleic acids

Correct answer: D

Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.

4. Medication for treating high blood cholesterol levels should not be used for most people unless:

• A. The patient has at least three major risk factors for coronary heart disease
• B. The patient has been experiencing symptoms of coronary heart disease for at least three months
• C. The patient's medical insurance covers prescription drugs
• D. Treatment with Therapeutic Lifestyle Changes (TLC) alone is unsuccessful after three months

Correct answer: D

Rationale: The correct answer is choice D because medication for high cholesterol is typically not considered unless Therapeutic Lifestyle Changes (TLC), which include diet and exercise, have not proven effective after a three-month period. This approach ensures that lifestyle modifications are given a fair chance to lower cholesterol levels before resorting to medication. Choice A is incorrect because the number of risk factors for coronary heart disease does not dictate when to begin medication; it is about the effectiveness of lifestyle changes. Choice B is incorrect as the duration of coronary heart disease symptoms does not determine when to start medication; the focus is on the response to TLC. Choice C is incorrect because the coverage of prescription drugs by the patient's insurance does not influence the medical decision to use medication for high cholesterol; it is based on medical necessity and effectiveness of prior interventions.

5. A nurse at a provider's office is providing teaching to a client who is taking chemotherapy and losing weight. Which of the following should the nurse recommend to increase calorie and protein intake? (Select one that does not apply.)

• A. Top yogurt with fruits.
• B. Add cream to soups.
• C. Use milk instead of water in recipes.
• D. Increase fluids during meals.

Correct answer: D

Rationale: The correct recommendation to increase calorie and protein intake for a client taking chemotherapy and losing weight is to add cream to soups (choice B), as it provides additional calories and proteins. Using milk instead of water in recipes (choice C) can also increase the calorie and protein content. Topping yogurt with fruits (choice A) can be a healthy choice but may not significantly increase calorie and protein intake. Increasing fluids during meals (choice D) may fill up the stomach, potentially reducing the intake of solid foods, which is not ideal when trying to increase calorie and protein consumption.
