Q

True or False: Parents should not get involved in a child’s blood collection. Instead, another nurse or phlebotomist should be called in to help.

A

False. Parent involvement should be encouraged, and it is your responsibility to explain how the parent can assist by holding, distracting, and soothing their child during the procedure. However, if the parent does not wish to be in the room during the procedure, you may ask another health care worked to assist.

Q

True or False: The room location of a child’s venipuncture procedure holds no importance, as venipuncture equipment can be moved anywhere.

A

False. For psychological reasons, the best room location for a painful procedure is a treatment room away from the child’s bed or play room. If the child cannot be moved to a treatment room, privacy should be maintained by drawing a curtain between the beds and speaking in a calm, quiet manner.

Q

Describe the vertical restraining technique for children.

A

The child is held on the parent’s lap. As the parent hugs and holds the child’s body and the arm not being used, the health care worker can firmly hold the other arm to perform the procedure.

Q

Describe the horizontal, or supine, restraining technique for children.

A

A baby can be easily held in this position. However, more restraint may be required to hold an older child. The child can lay supine with the health care worker on one side of the bed and the parent on the opposite side. The parent can lean over the child to restrain the child’s unused arm while holding the opposite, extended arm securely for the healthcare worker.

Q

True or False: Neonates and infants under 3 months usually require the restraint of multiple nurses, as the infants do not know that it is better to stay still.

It contains blood from capillaries, venules, and arterioles, and fluids from the surrounding tissue. In addition, capillary blood is temporarily exposed to room air, which allows for a brief exchange of gases.

50
Q

If there are _______ in a capillary blood gas testing specimen, inaccuracies can occur.

A

Bubbles.

51
Q

Why is the first drop of blood wiped away in capillary blood collection?

Plastic Caps - used to close off the ends of the capillary tube.
Metal Filing - a.k.a. “flea” or “mixing wires.” Put inside the tube. Pulled by the magnet to mix the specimen.

Newborn babies (neonates) are routinely screened for a variety of metabolic and genetic defects by analysis of blood collected on a special filter paper.

55
Q

When is the first blood spot testing for screening performed on a neonate?

A

Before the newborn is 72 hours old (if collected before 24 hours after birth, a second specimen for screening must be acquired before 2 weeks of age).

56
Q

What does a filter paper used for capillary blood for neonatal screening look like? How is it used?

A

The filter paper has a line of circles. After the capillary puncture of the neonate, wipe away the first drop of blood and lightly touch the printed side of the paper with the blood drop to fill each printed circle (on one side only). Allow the blood to completely soak through in a single application.

57
Q

True or False: The filter paper should lightly touch the skin puncture site.

A

False. The filter paper must not touch the puncture site, only the blood, to prevent contamination. The paper should not touch anything before, during, or after collection.

58
Q

The filter paper should dry for a minimum of _ hours on a dry, flat, ____________ surface.

A

4; nonabsorbent.

59
Q

List at least 3 interferences that can occur with newborn screening collections.
