A nurse is preparing to check the capillary blood glucose level of a school-age child. Which of the following actions should the nurse plan to take?
Allow the skin antiseptic to dry prior to puncturing the child's finger.
Place a cool washcloth on the child's finger for 5 min prior to the procedure.
Test the first drop of blood obtained after puncturing the child's finger.
Puncture the center of the pad of the child's index finger.
The Correct Answer is A
Choice A rationale:
The correct answer is choice A. This action is crucial to ensure accurate capillary blood glucose testing. Allowing the skin antiseptic to dry before puncturing the child's finger helps prevent contamination of the blood sample, which can lead to inaccurate results. Wet antiseptic can dilute the blood sample and affect the glucose reading.
Choice B rationale:
This choice is incorrect because placing a cool washcloth on the child's finger is not standard practice before capillary blood glucose testing. While warmth can help increase blood flow and make the puncture process more comfortable, using a cool washcloth is not recommended, as it may constrict blood vessels and make it harder to obtain a sufficient blood sample.
Choice C rationale:
This choice is incorrect because testing the first drop of blood obtained after puncturing the child's finger is not recommended. The first drop of blood can be diluted with interstitial fluid and may not provide an accurate glucose reading. It's important to wipe away the first drop and use the subsequent drop of blood for testing.
Choice D rationale:
This choice is incorrect because puncturing the center of the pad of the child's index finger is not the recommended site for capillary blood glucose testing. The sides of the fingertip contain an adequate blood supply and are less painful for the child. Puncturing the center of the fingertip can be more painful and may not yield a sufficient blood sample.

Correct Answer is B
Explanation
Choice A rationale:
Administer pain medication. Administering pain medication is important for the preschooler's comfort, but it is not the nurse's priority action in this scenario. The priority is to ensure adequate circulation to the extremities, which can be assessed by checking capillary refill.
Choice B rationale:
Check capillary refill. This is the correct answer because the nurse's priority is to assess the child's circulation and tissue perfusion. In 90-90 traction, there is a risk of impaired circulation to the extremities due to the positioning. Checking capillary refill provides information about the adequacy of blood flow to the capillaries and is crucial for early detection of any circulation problems.
Choice C rationale:
Cleanse and dress the pin sites. While caring for the pin sites is important to prevent infection, it is not the priority action at this moment. Ensuring proper circulation and perfusion takes precedence over pin site care.
Choice D rationale:
Reposition the child every 2 hr. Repositioning the child is important to prevent complications associated with immobility, but it is not the nurse's priority action in this situation. The primary concern is to assess and address any circulation issues.
Correct Answer is B
Explanation
Choice A rationale:
Iron 100 mcg/dL The normal range for serum iron levels can vary based on age and gender, but typically, a range of 50 to 150 mcg/dL is considered normal. The provided value of 100 mcg/dL falls within this range and is not a cause for concern. Elevated iron levels can be indicative of hemochromatosis or other disorders, but this value is not concerning.
Choice B rationale:
Hemoglobin 8 g/dL Hemoglobin levels can vary by age and gender, but in general, a hemoglobin level of 8 g/dL is low and suggestive of anemia, a condition characterized by a reduced ability of the blood to carry oxygen. Anemia can lead to fatigue, weakness, and other symptoms, and the nurse should report this finding to the healthcare provider for further evaluation and management.
Choice C rationale:
Sodium 140 mEq/L The normal range for serum sodium levels is typically around 135 to 145 mEq/L. The provided value of 140 mEq/L falls within this normal range and is not a cause for concern. Deviations from this range can indicate various conditions, including dehydration or overhydration, but this value is within an acceptable range.
Choice D rationale:
Calcium 9 mg/dL The normal range for serum calcium levels can vary, but generally, a range of 8.5 to 10.5 mg/dL is considered normal. The provided value of 9 mg/dL falls within this range and is not significantly abnormal. Abnormal calcium levels can be indicative of various conditions, including thyroid disorders or kidney problems, but this value is not concerning.
