1. 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.

2. Which enzyme is most essential for the digestion of triglycerides found in butterfat?

• A. Gastric lipase
• B. Pepsin
• C. Mucus
• D. Intrinsic factor

Correct answer: A

Rationale: The correct answer is A: Gastric lipase. Gastric lipase is crucial for the digestion of short- and medium-chain triglycerides, such as those found in butterfat. Pepsin is involved in protein digestion, not lipid digestion. Mucus acts as a protective barrier in the stomach and does not play a direct role in lipid digestion. Intrinsic factor is involved in the absorption of vitamin B12 and is not related to the digestion of triglycerides.

3. Bones continuously lose and gain minerals. This ongoing process is called?

• A. reorganization
• B. reorienting
• C. demineralizing
• D. remodeling

Correct answer: D

Rationale: The correct answer is D, 'remodeling.' Remodeling is the process by which bones continuously lose and gain minerals, maintaining bone strength and integrity over time. 'Reorganization' (choice A), 'reorienting' (choice B), and 'demineralizing' (choice C) do not accurately describe the process of bones continuously losing and gaining minerals.

4. Which enzyme digests fiber in the large intestine?

• A. salivary amylase
• B. pancreatic amylase
• C. cellulase
• D. none of the above

Correct answer: D

Rationale: The correct answer is 'none of the above.' Human digestive enzymes like salivary amylase and pancreatic amylase cannot digest fiber. Instead, fiber is fermented by gut bacteria in the large intestine. Cellulase, which is an enzyme produced by some animals and microorganisms, can break down cellulose found in plants, but it is not a human digestive enzyme, making it an incorrect choice in this context.

5. The term associated with loss of taste is:

• A. Xerostomia
• B. Hypogeusia
• C. Dysphagia
• D. Anosmia

Correct answer: B

Rationale: The correct answer is B, 'Hypogeusia.' Hypogeusia refers to a diminished sense of taste, which can impact nutritional intake, especially in older adults. Xerostomia (choice A) is dry mouth, Dysphagia (choice C) is difficulty swallowing, and Anosmia (choice D) is the loss of the sense of smell. These conditions are different from loss of taste, making them incorrect choices for this question.
