1. Scurvy is caused by a deficiency of ascorbic acid (Vitamin C) because ascorbic acid is required for collagen synthesis. Is this statement true or false?

• A. TRUE
• B. FALSE
• C. Not applicable
• D. Not applicable

Correct answer: A

Rationale: The statement is accurate. Scurvy is indeed caused by a deficiency in ascorbic acid, which is another name for Vitamin C. This vitamin plays a crucial role in the synthesis of collagen, a protein that helps in the formation and strength of skin, blood vessels, tissues, and bones. When the body lacks Vitamin C, it cannot produce enough collagen, leading to symptoms associated with scurvy such as bleeding gums and weakened immunity. The choice 'False' is incorrect because it contradicts the proven medical and scientific understanding of the causes of scurvy. Choices 'C' and 'D' are marked as 'Not applicable' because the question only requires a true or false answer.

2. Which of the following converts starch to disaccharides, and this reaction occurs in the _____?

• A. pancreatic amylases, small intestine
• B. brush border enzymes, small intestine
• C. luminal enzymes, large intestine
• D. pancreatic amylases, pancreas

Correct answer: A

Rationale: The correct answer is A. Pancreatic amylases break down starch into disaccharides in the small intestine. This process occurs in the small intestine, not the large intestine or pancreas. Brush border enzymes act on disaccharides to break them down into monosaccharides, while luminal enzymes are not specifically involved in the conversion of starch to disaccharides.

3. A healthcare provider is assessing a client who has a stage III pressure ulcer that is healing poorly. The provider should identify that which of the following vitamin deficiencies increases the client’s risk for delayed wound healing?

• A. Vitamin C
• B. Vitamin D
• C. Vitamin E
• D. Vitamin B6

Correct answer: A

Rationale: Corrected Rationale: Vitamin C deficiency can impair collagen synthesis and delay wound healing, making it crucial for recovery from pressure ulcers. Incorrect Rationales: - Vitamin D deficiency is associated with bone health, not specifically wound healing. - Vitamin E deficiency can lead to neurological and immune system issues but is not directly linked to delayed wound healing. - Vitamin B6 deficiency can cause skin rashes and neurological symptoms but is not a primary factor in delayed wound healing.

4. In order to establish and maintain successful breastfeeding, which practice should a lactating mother try to follow?

• A. Initiate breastfeeding within 24 hours of birth
• B. Breastfeed on a schedule of every 2 to 3 hours
• C. Give a pacifier to an infant between feedings
• D. Find a breastfeeding support group to troubleshoot problems

Correct answer: D

Rationale: The correct answer is D. Finding a breastfeeding support group is crucial for a lactating mother to establish and maintain successful breastfeeding. This group can offer valuable advice, tips, and encouragement, helping the mother troubleshoot any issues that may arise during breastfeeding. Choices A, B, and C are incorrect because breastfeeding is a natural process that should not be overly scheduled, and giving a pacifier between feedings can interfere with establishing proper breastfeeding techniques.

5. Water loss can occur from each, except one. Which is the exception?

• A. Respiratory inflammation
• B. Strenuous exercise
• C. Diarrhea
• D. Perspiration

Correct answer: D

Rationale: The correct answer is D, Perspiration. Water loss can occur through respiration inflammation, strenuous exercise, and diarrhea. Perspiration, also known as sweating, is a mechanism by which the body regulates temperature and eliminates some waste products, but it is not a cause of water loss. The body loses water through sweating, but this loss is mainly for cooling purposes, and it is not a primary mechanism for water loss like respiration, exercise, or diarrhea.
