1. Which of the following is not correct?

A. energy density is a comparison of energy (kcals) content to the weight of food
B. if a food product contains a 15% daily value of calcium, that product is said to be a low source of calcium
C. MyPlate illustrates the 5 food groups
D.

Correct answer: B

Rationale: A product with 15% Daily Value (DV) of calcium is considered a good source, not a low source. Typically, anything 10-19% DV is considered a good source.

2. A nurse is providing anticipatory guidance to a client who has Phenylketonuria (PKU) and is planning a pregnancy. Which of the following information should the nurse include in the discussion?

A. Diet sodas should not be consumed more than two or three times a week.
B. Serum bilirubin should be monitored once or twice a month during pregnancy.
C. Breastfeeding will not prevent your baby from developing PKU.
D. A low-protein diet should be followed for three months before conception.

Correct answer: D

Rationale: A low-protein diet should be followed for three months before conception in individuals with PKU who are planning a pregnancy. This diet helps manage PKU by reducing phenylalanine levels, which is crucial for maternal and fetal health. Choices A, B, and C are incorrect. Choice A is not directly related to managing PKU, choice B focuses on a different aspect of care during pregnancy, and choice C is inaccurate as breastfeeding will not prevent a baby from developing PKU.

3. A client with Crohn's disease is being cared for by a nurse. Which of the following food choices aligns with the recommended diet for clients with Crohn's disease?

A. Vanilla milkshake
B. Buttered popcorn
C. Tossed green salad
D. Toast with jelly

Correct answer: C

Rationale: The correct answer is a 'Tossed green salad.' Clients with Crohn's disease often benefit from a low-residue diet, which includes easily digestible foods like leafy green vegetables found in a tossed green salad. This type of diet helps minimize gastrointestinal symptoms. Choices A, B, and D are not ideal for clients with Crohn's disease. Vanilla milkshake, buttered popcorn, and toast with jelly may exacerbate symptoms due to their high fat, fiber, or sugar content, which can be harder to digest.

4. The purpose of chest percussion and vibration is to loosen secretions in the lungs. The difference between the procedures is:

A. Percussion uses only one hand, while vibration uses both hands
B. Percussion delivers cushioned blows to the chest with cupped palms, while vibration gently shakes secretions loose
C. In both percussion and vibration, the hands are not on top of each other, and hand action is not in tune with the client's breath
D. Percussion slaps the chest to loosen secretions, while vibration shakes the secretions along with the inhalation

Correct answer: D

Rationale: Chest percussion involves the use of rhythmic tapping to dislodge mucus from the lungs, facilitating its movement toward the larger airways where it can be expelled. This technique is particularly important in conditions where mucus retention is a significant risk factor for infection. The key difference between chest percussion and vibration is that percussion involves slapping the chest to loosen secretions, while vibration involves shaking the secretions along with the inhalation, aiding in moving the loosened secretions upwards for easier removal. Choices A, B, and C do not accurately describe the main difference between chest percussion and vibration, making them incorrect.

5. Which of the following is NOT a physiological role of proteins?

A. Providing resistance to disease
B. Regulating fluid balance
C. Repairing tissue
D. Serving as the primary source of energy

Correct answer: D

Rationale: Proteins play a diverse range of physiological roles in the body, such as providing resistance to disease, regulating fluid balance, and repairing tissues. However, they are not the primary source of energy for the body. Carbohydrates and fats typically fulfill this role. Therefore, choice D is the correct answer, as it is not a function that proteins perform. Conversely, choices A, B, and C are all physiological functions of proteins, making them incorrect responses to this particular question.
