Correct Answer: A

Rationale: Immediate initiation of oral feedings is contraindicated post-abdominal surgery due to the risk of bowel complications such as paralytic ileus or anastomotic leak. Starting oral feedings immediately can increase the risk of these complications and hinder the healing process. It is crucial to wait until bowel function returns and the patient shows signs of tolerance before introducing oral feedings. Assessment of the surgical site, administration of opioid narcotics for pain management, and visitation at the bedside are essential components of postoperative care and should not be excluded.

Correct Answer: A

Rationale: Before giving digoxin, the nurse will assess the HR and rhythm. The dosage will be held and the prescriber notified if the HR is below 60 bpm or if the cardiac rhythm has changes. Digoxin can cause bradycardia and electrical changes in the heart.

Rationale: To calculate the corrected age of a premature child, you need to adjust for the weeks of prematurity. In this case, the child was born at 30 weeks gestation. From May 2, 2014, to August 5, 2014, is a span of 14 weeks. Subtracting the 30 weeks of gestation from the total time passed (14 weeks) gives the corrected age, which is 14 - 30 = -16 weeks. Since negative weeks are not relevant here, the corrected age is 0 weeks, which is equivalent to 2 weeks.

Correct Answer: D
