A nurse is assisting with the care of a newborn immediately following birth who has an omphalocele. Which of the following actions should the nurse take?

Choice A rationale While thermoregulation is critical for newborns, directly placing a newborn with an omphalocele under a radiant heat source without covering the exposed viscera first can lead to excessive fluid loss and potential hypothermia due to evaporation. The primary concern is protecting the exposed abdominal contents from injury and infection. Choice B rationale Positioning a newborn with an omphalocele in a supine position is generally appropriate, as it helps to keep the exposed viscera in a less compromised position. However, the most immediate and critical action is to protect the exposed organs from trauma, desiccation, and infection before considering positioning. Choice C rationale Using sterile plastic wrap to cover the viscera of a newborn with an omphalocele is a critical immediate nursing action. This creates a sterile barrier, prevents desiccation of the exposed abdominal contents, minimizes heat and fluid loss, and reduces the risk of infection, thus protecting the delicate organs until surgical repair. Choice D rationale Applying petroleum gauze to the exposed viscera is not the most appropriate or effective method for protecting an omphalocele. Petroleum gauze may stick to the delicate tissues, potentially causing trauma upon removal, and does not provide the same level of sterile barrier, moisture retention, or protection against environmental contaminants as sterile plastic wrap.
