1. Each statement is true of water-soluble vitamins, except one. Which is it?

• A. Act as coenzymes
• B. Deficiencies develop rapidly
• C. Daily intake is necessary
• D. Absorbed in the jejunum

Correct answer: B

Rationale: The correct answer is B. Water-soluble vitamins do not develop deficiencies rapidly because the body does not store them for long periods. They must be obtained through food constantly. Choice A is correct because water-soluble vitamins often act as coenzymes in various metabolic reactions. Choice C is correct as daily intake of water-soluble vitamins is necessary since they are not stored in the body. Choice D is incorrect as water-soluble vitamins are absorbed primarily in the small intestine, particularly in the duodenum and ileum, not the jejunum.

2. A nurse is instructing the mother of a toddler who has iron-deficiency anemia to increase iron in the child's diet in addition to the prescribed iron supplement. Which of the following foods should the nurse recommend?

• A. Skim milk
• B. Bananas
• C. Tuna fish
• D. Cucumbers

Correct answer: C

Rationale: Tuna fish is a good source of iron and would be beneficial for a toddler with iron-deficiency anemia. Skim milk, bananas, and cucumbers are not significant sources of iron and would not help in increasing the iron levels in the child's diet. Skim milk, in particular, can inhibit iron absorption due to its calcium content, which is important for the nurse to educate the mother about.

3. Which food is recommended for someone with lactose intolerance?

• A. Skim milk
• B. Cheese
• C. Lactose-free yogurt
• D. Whole milk

Correct answer: C

Rationale: Lactose-free yogurt is suitable for individuals with lactose intolerance as it has reduced lactose content.

4. Poor nutrition results in delayed eruption and exfoliation of deciduous teeth and increased dental caries. Increased caries susceptibility in at-risk children may be related to changes in salivary composition caused by malnutrition.

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: A

Rationale: Both statements are true. Poor nutrition can affect tooth development and increase the risk of dental caries in children.

5. When taking a blood pressure reading, where should the cuff be positioned?

• A. The cuff should be deflated fully before immediately starting a second reading for the same patient
• B. The cuff should be deflated quickly after being inflated to 180 mmHg
• C. The cuff should be large enough to wrap around the upper arm of the adult patient, positioned 1 cm above the brachial artery
• D. The cuff should be inflated to 30 mmHg above the estimated systolic BP based on palpation of the radial or brachial artery

Correct answer: D

Rationale: When measuring blood pressure, the cuff should be inflated to 30 mmHg above the estimated systolic blood pressure based on palpation of the radial or brachial artery. This ensures an accurate blood pressure measurement. Choices A, B, and C are incorrect. Deflating the cuff fully before starting a second reading (Choice A) does not directly relate to the position of the cuff during a reading. Deflating the cuff quickly after inflating to 180 mmHg (Choice B) is not recommended because it can potentially lead to inaccurate readings. While ensuring the cuff is large enough to wrap around the upper arm positioned 1 cm above the brachial artery is important (Choice C), this alone does not guarantee an accurate blood pressure reading. The correct inflation based on palpation is the key element for accuracy, which is why Choice D is correct.
