A nurse is caring for a client who is postoperative following a bowel surgery and has an NG tube connected to low intermittent suction. Which of the following assessment findings should indicate to the nurse that the NG tube might not be functioning properly?

- A. Clothing the newborn in light cotton is not recommended because it can block the light from reaching the skin, which is necessary for the treatment of hyperbilirubinemia through phototherapy.
- B. Checking the newborn's temperature every 8 hours is not frequent enough; during phototherapy, it is important to monitor the newborn's temperature more frequently to ensure they do not become too cold or too warm as a result of the therapy.
- C. Administering water between feedings is not recommended as it can interfere with the newborn's feeding schedule and nutrition; breast milk or formula provides adequate hydration unless otherwise indicated by a healthcare provider.
- D. Placing the newborn 45 cm (18 in) from the light source is the correct intervention. This distance allows for optimal exposure to the light while ensuring the safety and comfort of the newborn, as recommended in clinical guidelines for effective phototherapy.

A. Crepitus is a finding associated with subcutaneous emphysema or gas accumulation under the skin, typically not directly related to right ventricular heart failure.

B. Right ventricular heart failure can lead to increased pressure in the pulmonary artery, resulting in symptoms such as dyspnea, fatigue, and possibly right-sided heart murmurs.

C. Hepatosplenomegaly (enlargement of the liver and spleen) is more commonly associated with conditions such as liver cirrhosis, not specifically right ventricular heart failure.

D. Confusion is not typically associated with right ventricular heart failure unless there are complications such as hypoxemia or impaired cerebral perfusion.
