A nurse in the emergency department is assessing a newly-admitted infant. Which of the following findings is an early indication of hypoxemia?
Hypoventilation
Tachypnea
Nonproductive cough
Nasal stuffiness
The Correct Answer is B
Choice A reason: Hypoventilation is a late sign of hypoxemia and is characterized by an abnormally slow breathing rate, reducing oxygen intake and increasing carbon dioxide in the blood.
Choice B reason: Tachypnea, or rapid breathing, is an early sign of hypoxemia as the body attempts to increase oxygen levels by breathing more quickly.
Choice C reason: A nonproductive cough is not directly related to hypoxemia, which is a deficiency in the amount of oxygen reaching the tissues.
Choice D reason: Nasal stuffiness is not a specific indicator of hypoxemia and can be associated with various conditions.

Explanation
Choice A reason: Bed rest is not a specific treatment for Hirschsprung's disease. While rest may be part of preoperative care, it does not address the underlying issue of the disease⁹.
Choice B reason: Surgery is the definitive treatment for Hirschsprung's disease. The pull-through procedure is commonly used to remove the affected section of the colon and connect the healthy part to the anus⁷.
Choice C reason: An NG tube may be used for decompression if there is a bowel obstruction, but it is not a treatment for Hirschsprung's disease itself. Surgery is required to correct the absence of nerve cells in the colon⁹.
Choice D reason: A high-fiber diet is not recommended before surgery as it may increase the risk of enterocolitis and bowel obstruction in patients with Hirschsprung's disease⁹.
