A nurse in an emergency department is assessing an infant who is dehydrated. Which of the following findings should the nurse expect?

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.

When caring for a child with acute appendicitis, the nurse should anticipate an elevated white blood cell count (WBC) in the laboratory values. A high WBC count is a common finding in acute appendicitis, as it indicates an inflammatory response and infection in the body. The body's immune system responds to the inflammation caused by the infected appendix, leading to an increase in WBCs to fight off the infection.
The other options are not necessarily specific to acute appendicitis:
A. RBC 4.2 million/mm³: The red blood cell count (RBC) measures the number of red blood cells in the bloodstream. This value may be within the normal range, but it is not the primary marker for diagnosing or monitoring acute appendicitis.
B. Lymphocytes 3,000/mm3: Lymphocytes are a type of white blood cell involved in the body's immune response. While changes in lymphocyte levels can occur during inflammation, it is not the primary marker for diagnosing or monitoring acute appendicitis.
C. Neutrophils 3.000/mm³: Neutrophils are a type of white blood cell that increases in response to infection and inflammation. However, the absolute neutrophil count is not as relevant as the overall WBC count in determining the presence and severity of acute appendicitis.
