Nursing Elites

1. Is it a good idea for an athlete to eliminate all fat from his diet in order to stay lean?

• A. yes, because dietary fat is stored easily in fat cells and can't be used for energy
• B. no, because fats provide energy during prolonged exercise
• C. yes, because fat is stored under the skin and causes the body to overheat
• D. no, because excess fat is converted to glycogen and stored in the muscles

Correct answer: B

Rationale: Fat is an essential energy source during prolonged exercise, so eliminating it entirely from the diet is not advisable for athletes.

2. Proteolytic enzymes are most likely to break down which food type?

• A. Carbohydrates
• B. Proteins
• C. Fats
• D. Lipids

Correct answer: B

Rationale: Proteolytic enzymes target proteins for breakdown into amino acids. Carbohydrates are broken down by enzymes like amylase, while fats are broken down by lipase. Lipids, which include fats, are not specifically targeted by proteolytic enzymes.

3. During early tooth development, vitamin A deficiency leads to enamel hypoplasia and defective dentin formation. Because of its effect on soft tissues and bone, vitamin A contributes to normal spacing of teeth.

• 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. The effect of vitamin A on the growth of soft tissues and bones naturally extends to the teeth and surrounding structures. Enamel hypoplasia, involving defective enamel matrix and incomplete calcification of enamel and dentin, can be due to vitamin A deficiency. The effect of this vitamin upon surrounding bone directly affects spacing patterns of the teeth within the bone and dentition. Choice A is correct because both statements accurately describe the influence of vitamin A on tooth development. Choices B, C, and D are incorrect as they do not reflect the accuracy of the statements provided.

4. What is the fundamental difference between nursing diagnoses and collaborative problems?

• A. Collaborative problems are managed by nurses using physician-prescribed interventions.
• B. Collaborative problems can be addressed by independent nursing interventions.
• C. Physician-prescribed interventions are incorporated into nursing diagnoses.
• D. Nursing diagnoses include physiologic complications that nurses monitor to detect status changes.

Correct answer: B

Rationale: The correct answer is B, as collaborative problems necessitate the collective expertise and skills of numerous healthcare professionals, including nurses. These problems can be dealt with through independent nursing interventions in cooperation with other team members. Option A is incorrect because collaborative problems aren't strictly managed with physician-prescribed interventions. Option C is incorrect because nursing diagnoses aim at identifying and treating actual or potential health issues, rather than merely integrating physician-prescribed interventions. Option D is incorrect because nursing diagnoses aim at identifying patient issues, not solely physiologic complications, and guide the necessary nursing care, not just monitor for changes.

5. A nurse is preparing to administer a gavage feeding via a nasogastric tube to a preterm newborn who is receiving supplemental oxygen. Which of the following actions should the nurse take?

• A. Stabilize the tube with tape to the newborn’s cheek.
• B. Remove supplemental oxygen during the feeding.
• C. Measure the stomach aspirate prior to the feeding.
• D. Place the newborn on their left side for 30 minutes after the feeding.

Correct answer: C

Rationale: Measuring the stomach aspirate prior to the feeding is crucial to ensure the correct placement and function of the nasogastric tube. This step helps prevent complications such as aspiration or improper feeding. Choice A is incorrect as stabilizing the tube with tape to the newborn’s cheek can cause discomfort and skin irritation. Choice B is incorrect because removing supplemental oxygen during the feeding may compromise the newborn's respiratory status. Choice D is incorrect because placing the newborn on their left side for 30 minutes after the feeding is not a standard practice and is unnecessary for administering gavage feeding.
