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.

Correct Answer is B
Explanation
Choice A reason: Positioning a child supine after a tonsillectomy is not recommended due to the risk of respiratory complications. Elevating the head of the bed is preferred to prevent aspiration and facilitate breathing.
Choice B reason: Administering analgesics on a schedule is crucial for effective pain management. It helps maintain consistent pain relief, which is important for encouraging fluid intake and preventing dehydration.
Choice C reason: Encouraging a child to blow their nose gently after a tonsillectomy is not advised because it can increase the risk of bleeding. Instead, gentle mouth breathing and avoiding nose blowing are recommended.
Choice D reason: Offering orange juice after a tonsillectomy is not ideal as acidic beverages can irritate the throat. It's better to provide non-acidic fluids like water or apple juice to keep the child hydrated.
Correct Answer is A
Explanation
Choice A reason: A blood creatinine level of 1.3 mg/dL is elevated for a school-age child and indicates impaired kidney function, which is a concern in acute glomerulonephritis.
Choice B reason: A urine output of 550 mL in 24 hours is within the normal range for a school-age child and does not need to be reported unless there is a significant change.
Choice C reason: A blood pressure of 100/74 mm Hg is within the normal range for a school-age child and does not indicate an immediate concern.
Choice D reason: A BUN level of 8 mg/dL is within the normal range for a school-age child and does not need to be reported unless there is a significant change.
