Explanation

A. Urine output of 50 mL in 2 hr: This is within normal limits for a child and does not indicate an immediate concern.

A. Apply a transparent dressing to the site after the venipuncture. B. Apply a cold compress to the site prior to obtaining the sample. C. Perform an Allen test prior to obtaining the blood sample. D. Obtain the sample using venipuncture.

Correct Answer is D

Explanation

A. Apply a transparent dressing to the site after the venipuncture. A pressure dressing is more appropriate to control bleeding in a child with hemophilia.
B. Apply a cold compress to the site prior to obtaining the sample. Cold compresses reduce swelling but are not required prior to venipuncture.
C. Perform an Allen test prior to obtaining the blood sample. An Allen test is used to evaluate arterial circulation before arterial blood sampling, not for venipuncture.
D. Obtain the sample using venipuncture. Venipuncture is preferred over heel sticks or finger pricks for children with hemophilia because it minimizes trauma and bleeding.
