1. Cyanocobalamin is a form of which vitamin?

• A. Vitamin B1
• B. Vitamin B2
• C. Vitamin B3
• D. Vitamin B12

Correct answer: D

Rationale: Cyanocobalamin is a synthetic form of Vitamin B12. Vitamin B12 is essential for various bodily functions, including red blood cell formation, neurological function, and DNA synthesis. It is not to be confused with Vitamin B1, B2, or B3, which are separate vitamins with different roles in the body.

2. 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.

3. Mr. Bradley has been advised to limit his dairy product intake. What principle regarding fluid intake should be followed?

• A. Gelatin, soups, fruit ices, and frozen fruit bars contribute to your fluid intake
• B. Drink milk in moderation
• C. Increase fiber intake
• D. Limit protein intake

Correct answer: A

Rationale: For patients with kidney disease, it's important to manage fluid intake from all sources, including foods like gelatin and soups, which can contribute to fluid overload.

4. Each statement is true of swallowing and processing food, except one. Which is the exception?

• A. The swallowing reflex moves a bolus into the esophagus
• B. A bolus is a mass of food
• C. The bolus is transported to the stomach by osmosis and gravity
• D. The bolus penetrates the diaphragm through the esophageal hiatus

Correct answer: C

Rationale: The correct answer is C. The bolus is not transported to the stomach by osmosis and gravity, but by peristalsis. Peristalsis is the involuntary constriction and relaxation of muscles to push the bolus through the digestive system. Choices A, B, and D are correct statements. A bolus is indeed a mass of food, the swallowing reflex does move the bolus into the esophagus, and the bolus does not penetrate the diaphragm through the esophageal hiatus; instead, it enters the stomach through the lower esophageal sphincter.

5. The ideal time to begin taking folate to prevent neural tube defects is:

• A. Before conception
• B. Once pregnancy begins
• C. At 6 weeks
• D. Upon completion of the first trimester

Correct answer: A

Rationale: Folate is crucial before conception to prevent neural tube defects. Neural tube development occurs early in pregnancy, often before a woman knows she is pregnant.
