Answer to Question 1

ANS: C
The Allen test assesses the circulation of the radial, ulnar, or brachial arteries before arterial puncture. The Allen test is used before arterial punctures, not heel sticks, venipunctures, or lumbar punctures.

Answer to Question 2

ANS: A
Because of the urgency of the child's condition, conscious sedation should be used for the procedure. Pediatric spinal trays have smaller needles than do adult trays. Reassuring the parents that the test is simple, painless, and risk free is incorrect information. A spinal tap does have associated risks, and analgesia will be given for the pain. EMLA (a eutectic mixture of anesthetics) should be applied approximately 60 minutes before the procedure. The emergency nature of the spinal tap precludes its use.
