A nurse is assessing a newborn following a vaginal delivery. Which of the following findings should the nurse report to the provider?

- A. Correct. The nurse should initiate continuous cardiac monitoring because a magnesium level of 2.7 mEq/L indicates hypermagnesemia, which can cause cardiac dysrhythmias, hypotension, and bradycardia.

- B. Incorrect. The nurse should not administer potassium chloride to a client who has hypermagnesemia because it can worsen the condition by increasing the intracellular magnesium level and decreasing the serum calcium level.

- C. Incorrect. The nurse should not provide a diet rich in legumes, nuts, and green vegetables to a client who has hypermagnesemia because these foods are high in magnesium and can increase the serum magnesium level.

- D. Incorrect. The nurse should not monitor the client for tetany because tetany is a sign of hypomagnesemia, not hypermagnesemia. Hypomagnesemia can cause neuromuscular excitability, muscle spasms, and positive Chvostek's and Trousseau's signs

The correct answer is D

Choice A Reason: While croup can be serious, an O2 saturation of 92% on room air is generally stable. This child's condition is concerning but not immediately life-threatening.

Choice B Reason: A 15-year-old adolescent who is 2 hours postoperative following an open reduction and internal fixation of the left ankle and is requesting pain medication is in need of comfort measures. Postoperative pain management is important for recovery, but it is not a priority over more critical conditions.

Choice C Reason: A 3-year-old toddler with gastroenteritis, moderate dehydration, and two loose bowel movements over the past 24 hours requires rehydration and monitoring. The normal range for bowel movements varies, but two loose stools in 24 hours for a toddler with gastroenteritis is not unusual. Dehydration can become severe, so this child should be assessed soon, but it is not the most urgent case.

Choice D Reason: This child's sudden relief from pain could be a sign of a perforated appendix, a serious complication that requires immediate medical attention. Therefore, this child's condition is the most urgent and requires immediate assessment.
