A nurse is caring for a child who is 2 hr postoperative following a tonsillectomy. Which of the following fluid items should the nurse offer the child at this time?

A. Cranberry juice
Explanation: Acidic and citrus juices, including cranberry and orange juice, should be avoided in the immediate postoperative period as they can be irritating to the surgical site and may increase the risk of bleeding.
B. Crushed ice
Explanation:
After a tonsillectomy, it's important to provide cold and clear fluids to soothe the throat and prevent bleeding. Crushed ice is a suitable option as it helps keep the throat cool and provides hydration without irritating the surgical site. Cold liquids can help minimize swelling and provide comfort.
C. Vanilla milkshake
Explanation: While milkshakes may be appealing, dairy products can coat the throat and may not be recommended immediately after surgery. Additionally, it's crucial to avoid using straws, as sucking can increase the risk of bleeding.
D. Orange juice
Explanation: As mentioned earlier, citrus juices like orange juice can be irritating to the surgical site and are not recommended in the early postoperative period after a tonsillectomy. It's essential to choose clear and non-acidic fluids to support healing and prevent complications.

A. It is inconclusive
Explanation: A serum phenylalanine level within the normal range is considered conclusive in ruling out phenylketonuria. Inconclusive results typically occur when there are issues with the sample or testing process.
B. It is negative
Explanation:
A serum phenylalanine level of 1 mg/dL (60.5 mcmol/L) in a 2-week-old infant is within the normal range. In the context of phenylketonuria (PKU) screening, a "negative" result means that the phenylalanine levels are within the expected range, and there is no evidence of phenylketonuria.
C. It requires rescreening at age 6 weeks.
Explanation: If the initial screening result is within the normal range, rescreening at age 6 weeks may not be necessary for phenylketonuria. The timing and need for rescreening may vary based on local protocols and individual patient factors.
D. It is positive
Explanation: A positive result for phenylketonuria would indicate that the serum phenylalanine levels are elevated, suggesting a potential diagnosis of PKU. In this case, the result is negative, meaning there is no evidence of PKU.
