Physiologic jaundice in a newborn can be caused by:

Correct Answer: C

Rationale: Physiologic jaundice in a newborn, also known as neonatal jaundice, is a common condition in newborns characterized by yellow discoloration of the skin and eyes due to elevated levels of bilirubin in the blood. In newborns, the liver is not fully developed, leading to an inability to efficiently process and excrete bilirubin. Bilirubin is a byproduct of the breakdown of red blood cells, and in newborns, the liver may not yet be able to efficiently bind bilirubin for excretion, leading to its accumulation in the blood and manifesting as jaundice. Physiologic jaundice typically occurs around 2 to 4 days after birth and usually resolves on its own without treatment as the baby's liver matures and becomes more efficient at processing bilirubin.

Rationale: In this scenario, the patient developing a low-grade fever post-operatively along with diminished breath sounds could indicate the possibility of atelectasis or pneumonia. The most appropriate actions for the nurse to take to prevent complications in this situation would be to encourage coughing and deep breathing (to help clear secretions and improve lung expansion) and ambulate the patient as ordered (to promote lung ventilation and prevent further complications). Administering antibiotics, acetaminophen for fever management, and decreasing fluid intake may be considered based on the healthcare provider's assessment and orders, but the immediate nursing interventions to address the presenting symptoms are encouraging coughing and deep breathing and ambulating the patient.
