Correct Answer: C

Rationale: The correct recommendation for decreasing the number and total volume of emesis in an infant with gastroesophageal reflux is to thicken feedings and enlarge the nipple hole. Thicker feedings can reduce the frequency and volume of emesis by making the food less likely to be regurgitated. Enlarging the nipple hole helps ensure the thickened feedings can pass through. Surgical therapy (Choice A) is not the initial recommendation for managing gastroesophageal reflux in infants. Placing the infant in a prone position for sleep after feeding (Choice B) is not recommended due to the increased risk of sudden infant death syndrome (SIDS). Reducing the frequency of feeding by encouraging larger volumes of formula (Choice D) can exacerbate the reflux symptoms.

Correct Answer: D

Rationale: Postoperative care should focus on monitoring changes in stooling patterns, which could indicate complications such as stenosis or obstruction. It is crucial to educate the family on the importance of promptly reporting any changes in stooling patterns to the healthcare provider. Options A and B are not recommended unless specifically ordered by the physician as they can potentially cause harm or discomfort postoperatively. Option C may not be appropriate immediately after surgery and should be guided by the healthcare provider's recommendations.

Correct Answer: C

Rationale: Corrected Rationale: Currant jelly-like stools, which contain blood and mucus, are characteristic of Meckel diverticulum. This symptom occurs due to the bleeding from the ectopic gastric mucosa present in the diverticulum. Steatorrhea (choice A) is not typically associated with Meckel diverticulum. Clay-colored stools (choice B) are seen in conditions affecting the biliary system. Loose stools with undigested food (choice D) may indicate malabsorption issues, but it is not specifically linked to Meckel diverticulum.

Correct Answer: B

Rationale: The correct answer is to place the baby on their back to sleep. This position is the most effective way to prevent sudden infant death syndrome (SIDS) according to research and recommendations from healthcare providers. Choice A, using a firm mattress, is important for infant safety but not as directly related to preventing SIDS. Keeping the room warm, as mentioned in choice C, is not recommended as it may increase the risk of SIDS. While breastfeeding has many benefits, choice D, breastfeeding exclusively is not the most effective method for preventing SIDS.

Correct Answer: B

Rationale: The correct answer is B: All are correct. High-fiber foods like oranges, lima beans, baked beans, and raisin bran cereal are effective in preventing constipation. Oranges are a good source of fiber, lima beans and baked beans are high in fiber content, and raisin bran cereal is also rich in fiber. Bananas, which are not listed but could be considered by some as a high-fiber food, are actually low in fiber and may not be as effective in preventing constipation. Therefore, the nurse should include all the options provided in the teaching to help prevent constipation effectively.
