What test should the nurse do as a precautionary measure before doing an arterial puncture to obtain an arterial blood sample?
 
  a. Allen test
  b. Smith test
  c. Venipuncture
  d. Cold compress

Question 2

It is important to make certain that sensory connectors and oximeters are compatible because incompatible wiring can cause which condition?
 
  a. Hyperthermia
  b. Electrocution
  c. Pressure necrosis
  d. Burns under sensors

Answer to Question 1

ANS: A
The Allen test determines the adequacy of collateral circulation in the extremity distal to the proposed puncture site. If the child does not have satisfactory circulation when the proposed artery is occluded, that extremity is not used. The Smith test, venipuncture, and a cold compress are not done before arterial blood gas sampling.

Answer to Question 2

ANS: D
Incompatible wiring can generate considerable heat at the tip of the sensor, resulting in partial- and full-thickness burns. Heat may be generated at the site of the sensor, but it will not result in generalized hyperthermia. Electrocution is not a possibility with oximeters. Pressure necrosis can occur from improperly applied sensors but not from incompatible wiring.
