After surgery yesterday for gastroesophageal reflux, the nurse finds that the infant has somehow removed the nasogastric (NG) tube. What nursing action is most appropriate to perform at this time?

Correct Answer: A

Rationale: The most appropriate action for the nurse to take in this situation is to notify the healthcare provider immediately. This is important as the removal of the NG tube can disrupt postoperative care, especially in terms of maintaining gastric decompression. Inserting a new NG tube without practitioner direction can be unsafe and is not within the nurse's scope of practice. Similarly, replacing the NG tube or leaving it out should be decided by the healthcare provider to ensure the infant's safety and appropriate postoperative care.

Correct Answer: D

Rationale: The correct answer is D: Colicky, cramping abdominal pain around the umbilicus. This type of pain is a common early sign of acute appendicitis. Rebound tenderness, choice A, is a later sign seen in the physical examination of a patient with appendicitis. Rectal bleeding, as described in choice B, is not typically associated with appendicitis. Abdominal pain that is relieved by eating, as mentioned in choice C, is more indicative of peptic ulcer disease rather than appendicitis.

Correct Answer: C

Rationale: When caring for a child with probable appendicitis, sudden relief from pain is a critical sign that could indicate perforation of the appendix. Perforation results in the release of pressure and inflammation, leading to a temporary relief of pain. Anorexia (loss of appetite) and decreased abdominal distention are symptoms commonly associated with appendicitis itself, not perforation. Bradycardia (slow heart rate) is not typically a direct manifestation of appendicitis or its complications.

Correct Answer: C

Rationale: Allowing the child to assume a position of comfort is appropriate as it helps alleviate discomfort without the risk of complications. Placing the child in the Trendelenburg position could increase intra-abdominal pressure and worsen the condition. Applying moist heat may lead to vasodilation and potential perforation in case of appendicitis. Administering a saline enema can be harmful if the appendix is inflamed or perforated.

Correct Answer: B

Rationale: The correct answer is B. Meckel diverticulum often presents with intestinal bleeding, which can vary in severity. It is a congenital condition, meaning it is present from birth, not acquired during childhood (choice A). Meckel diverticulum is slightly more common in males than in females, so it does not occur more frequently in females (choice C). While some cases of Meckel diverticulum may require surgical intervention, medical interventions can also be sufficient to treat the problem, so it is not always necessary to resort to surgery (choice D).
