A nurse is preparing to measure an infant's vital signs. The nurse should use which of the following sites to assess a heart rate?

A. Broth: While broth can be a source of fluids, it does not contain the appropriate balance of electrolytes needed to rehydrate the body effectively. Gastroenteritis can cause significant fluid and electrolyte loss, so an oral rehydration solution (ORS) with the right proportions of salts and sugars is essential to replace these losses adequately.
B. Diluted apple juice: Diluted apple juice may not provide the proper electrolyte balance needed for rehydration in cases of gastroenteritis. In fact, apple juice is not recommended during episodes of acute gastroenteritis, as it can worsen diarrhea due to its high sugar content. This can lead to further dehydration and discomfort.
C. Oral rehydration solution (ORS): This is the correct answer. Oral rehydration solution is specifically designed to replace lost fluids and electrolytes in cases of gastroenteritis. It contains the right balance of salts and sugars to facilitate effective absorption in the intestines and help rehydrate the body. ORS is the recommended fluid for managing dehydration caused by gastroenteritis in children.
D. Water: While water is essential for hydration, it is not enough to effectively treat dehydration caused by gastroenteritis. Plain water does not contain the necessary electrolytes like sodium, potassium, and chloride, which are lost during episodes of diarrhea and vomiting. Giving water alone may not adequately rehydrate the child and could potentially worsen the dehydration.

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.
