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.

Correct Answer: B

Rationale: The correct answer is B. Most umbilical hernias in newborns resolve on their own by 3 to 5 years of age without the need for surgical intervention, unless complications arise. Surgery is not typically recommended for umbilical hernias in newborns due to the high rate of spontaneous resolution. Aggressive treatment is not necessary as umbilical hernias are typically benign and not associated with high mortality. Taping the abdomen is not recommended as it can cause skin irritation and does not speed up the resolution of the hernia.

Correct Answer: B

Rationale: Postoperative teaching should focus on assessing bowel function to ensure the colostomy is functioning properly. This includes monitoring stool output, color, consistency, and signs of infection or blockage. Choice A, dilating the stoma, is not recommended without healthcare provider guidance, as it can lead to complications. Choice C, limitation of physical activities, may not be as crucial immediately after colostomy creation. Choice D, measures to prevent prolapse of the rectum, is more relevant for conditions like rectal prolapse and not specifically for a colostomy.

Correct Answer: D

Rationale: Mid-upper arm circumference is a good indicator of muscle mass and fat stores, reflecting a child's nutritional status. It is particularly useful in assessing malnutrition, as it is less affected by fluid retention or dehydration compared to other anthropometric measurements. Weight can fluctuate due to factors like hydration status, making it less reliable as a sole indicator of nutritional status. Height reflects growth but may not directly indicate current nutritional status. Head circumference is more related to brain growth and development rather than overall nutritional status.

Correct Answer: C

Rationale: Frequent spitting up is indeed a common symptom of gastroesophageal reflux in infants. It is caused by the backward flow of stomach contents into the esophagus, leading to infants regurgitating milk or formula shortly after feeding. Projectile vomiting (choice A) is more commonly associated with conditions like pyloric stenosis rather than gastroesophageal reflux. Bilious vomiting (choice B) often indicates an obstruction in the gastrointestinal tract. Diarrhea (choice D) is not typically a primary symptom of gastroesophageal reflux in infants.
