A nurse is collecting data from a child who is 1 hr postoperative following a tonsillectomy. Which of the following findings is the nurse's priority?

A. Temperature of 37.2° C (99.0° F): A temperature of 37.2° C is within the normal range and does not necessarily indicate infection. Mild temperature elevations are common in the immediate postoperative period due to inflammatory responses rather than infection, which typically presents with more significant fever.

B. Elevated WBC count: An elevated white blood cell (WBC) count is a classic and early indicator of infection. It reflects the body's immune response to a bacterial or viral invasion, and postoperative infections often present with leukocytosis, making it a key finding to monitor closely.

C. Pain rating of 4 on a scale of 0 to 10: Moderate pain is expected after surgery and does not, by itself, suggest infection. Postoperative pain should be assessed in context with other symptoms like redness, swelling, or drainage; pain alone, especially if stable, is not definitive for infection.

D. Increased urinary output: Increased urinary output is generally a positive sign of good kidney perfusion and hydration status. A decrease, not an increase, in urinary output would be more concerning postoperatively and could suggest complications, but not necessarily infection.

A. Position the client's finger above their heart: The finger should be positioned below the level of the heart to encourage blood flow, making it easier to obtain a sufficient blood sample for testing. Elevating the finger would decrease blood flow and make collection more difficult.

B. Apply sterile gloves prior to performing the test: Clean, non-sterile gloves are sufficient for routine blood glucose monitoring. Sterile gloves are not necessary unless performing procedures that require a sterile environment, such as surgery or central line dressing changes.

C. Puncture the side of the client's finger: The sides of the fingertips have fewer nerve endings compared to the pads, making the procedure less painful. Additionally, puncturing the side helps promote better blood flow and reduces the risk of bruising and soreness.

D. Milk the finger site: Milking or squeezing the finger excessively can cause hemolysis or contamination of the blood sample with tissue fluid, leading to inaccurate glucose readings. Gentle pressure may be used if needed, but forceful milking should be avoided.
