Which of the following are examples of mechanical digestion? Select all that apply.
- A. Heat
- B. Segmentation
- C. Option B and D
- D. Peristalsis
Correct Answer: C
Rationale: Mechanical digestion involves physical movements that break down food in the digestive tract. Segmentation (choice B) and peristalsis (choice D), which are both movements of the muscles in the digestive tract, are examples of this type of digestion. Heat (choice A), on the other hand, is related to chemical digestion, not mechanical digestion. Therefore, choice C (Option B and D) is the correct answer as it includes both examples of mechanical digestion provided in the choices. Choices A and D are incorrect because heat (choice A) is not a mechanical digestion process, and peristalsis (choice D) is a movement that helps propel food along the digestive tract but is not directly involved in breaking down food physically.

According to the DASH Eating Plan, Carmen's daily sodium intake should not exceed how many milligrams to ensure the plan's effectiveness?
- A. 1000 milligrams
- B. 2500 milligrams
- C. 3000 milligrams
- D. 1500 milligrams
Correct Answer: D
Rationale: The DASH Eating Plan is designed to lower blood pressure and is most effective when daily sodium intake is limited to 1500 milligrams or less. Therefore, choice D is the correct answer. Choices A (1000 milligrams), B (2500 milligrams), and C (3000 milligrams) are incorrect because they either fall below or exceed the recommended daily sodium intake for the DASH Eating Plan.
What information should a working mother who wants to continue breastfeeding her infant by occasionally pumping milk ahead of time be given to help her successfully maintain breastfeeding?
- A. Breast milk can be refrigerated for up to 4 days
- B. Breast milk stored in a deep freezer can be kept for up to 12 months
- C. Heating breast milk in the microwave can degrade its nutritional quality
- D. Breast milk can be expressed either by hand or with an electric pump
Correct Answer: D
Rationale: The correct answer is D. This information is crucial as it informs the mother of her options for expressing milk, which is the first step in being able to store and later feed it to her child while she's away at work. Choice A has been corrected to state that breast milk can be refrigerated for up to 4 days, providing a more accurate storage timeframe. Choice B has been revised to indicate that breast milk stored in a deep freezer can be kept for up to 12 months, aligning with the recommended storage duration. Choice C now highlights that heating breast milk in the microwave can degrade its nutritional quality, emphasizing the importance of using proper methods for warming breast milk and avoiding potential harm to the baby's health and well-being.
What is the first thing you should do before sharing information with a patient?
- A. Provide background knowledge
- B. Ask for permission
- C. Remove personal protective equipment (PPE)
- D. Remind the patient that you are the authority
Correct Answer: B
Rationale: Before sharing information with a patient, it is essential to ask for their permission. This action respects the patient's autonomy and encourages their participation in the learning process. Asking for permission establishes a foundation of trust and partnership between the healthcare provider and the patient. Providing background knowledge (Choice A) is important, but it should come after receiving consent to share information. Removing personal protective equipment (Choice C) is not related to the communication process. Reminding the patient that you are the authority (Choice D) is inappropriate as it can undermine the patient's autonomy and hinder effective communication in a patient-centered care approach.
Each is a characteristic manifestation of necrotizing ulcerative gingivitis (NUG), except one. Which is the exception?
- A. Gingival erythema
- B. Necrosis of interdental papilla
- C. Marasmus
- D. Metallic taste and foul odor
Correct Answer: C
Rationale: The correct answer is C: Marasmus. Marasmus is a form of severe malnutrition and is not a direct manifestation of necrotizing ulcerative gingivitis (NUG). Choices A, B, and D are all characteristic manifestations of NUG. Gingival erythema, necrosis of interdental papilla, and metallic taste with foul odor are commonly associated with NUG due to the inflammatory and necrotic nature of the condition.
A patient on a low-sodium diet should avoid which of the following foods?
- A. Fresh fruits
- B. Unsalted nuts
- C. Canned soup

Fresh fruits (Choice A) are typically low in sodium and a good choice for a low-sodium diet. Unsalted nuts (Choice B) are also low in sodium and can be included in a low-sodium diet. Plain rice (Choice D) is a low-sodium food and can be part of a low-sodium diet.
