A nurse is obtaining vital signs from a 2-month-old infant. The infant's heart rate is 190/min and his temperature is 40° C (104° F). The father asks the nurse why the infant's heart is beating so fast. Which of the following responses by the nurse is appropriate?

For a 6-month-old infant who has undergone the repair of an intussusception, the nurse should select an oral electrolyte solution. This solution is specifically designed to replace lost fluids and electrolytes due to vomiting or diarrhea, which is crucial in preventing dehydration in infants.

Options A, B, and C are not suitable choices for an infant in this situation:

A. Half-strength orange juice: Citrus juices, including orange juice, are not recommended for infants under 12 months old. They are acidic and may cause stomach upset or diarrhea.

B. Sterile water: Sterile water does not contain the necessary electrolytes, and offering plain water to an infant after surgery or during an illness can lead to electrolyte imbalances and further dehydration.

C. Half-strength infant formula: Diluting infant formula can lead to inadequate nutrition for the infant. The baby requires appropriate nutrition to support recovery after surgery, and diluting formula can be harmful.

D. An oral electrolyte solution is the best choice as it helps maintain proper hydration and electrolyte balance in the infant's body during the recovery period. If the infant tolerates the oral electrolyte solution well and is not at risk for aspiration, the healthcare provider may gradually advance the diet to include other clear liquids and then slowly reintroduce regular infant formula or breast milk as appropriate. The healthcare provider's instructions should be followed carefully to support the infant's recovery and ensure adequate nutrition.

Correct answer: B

A. Increased pain: Increased pain is a common and expected finding after a tonsillectomy. The surgical removal of tonsils creates wounds in the throat, which can cause discomfort and pain during the healing process. However, increased pain alone is not a specific manifestation of hemorrhage. Hemorrhage would be indicated by other signs, such as drooling, frequent swallowing, or vomiting blood.

B. Frequent swallowing: This can indicate that the child is swallowing blood, which is a common sign of bleeding at the surgical site. Children might not always show obvious signs of bleeding in the mouth, so frequent swallowing can be a subtle but critical indicator of hemorrhage.

C. Poor fluid intake: Poor fluid intake is a common concern after a tonsillectomy due to postoperative pain and discomfort in the throat. The child may be reluctant to drink or eat initially because of their sore throat. However, poor fluid intake alone is not an indicative sign of hemorrhage. Hemorrhage would present with other symptoms, such as drooling, frequent swallowing, or vomiting blood.

D. Drooling:While drooling can occur due to discomfort, pain, or difficulty swallowing, it is not as specific or immediate a sign of hemorrhage as frequent swallowing.
