Which of the following actions for sterilization of instruments occurs prior to using an autoclave?

A.

Wrapping hinged instruments in the open, unlocked position

B.

Allowing the temperature of the autoclave to reach 200° F before timing

C.

Using a ballpoint pen to label contents

D.

Stacking wrapped packages tightly into the autoclave

Answer and Explanation

The Correct Answer is A

A. Wrapping hinged instruments in the open, unlocked position: Hinged instruments should be wrapped in the open, unlocked position to ensure that steam can penetrate all surfaces for effective sterilization.
B. Allowing the temperature of the autoclave to reach 200° F before timing: The autoclave should reach the required temperature (typically 250°F or 121°C) for the appropriate amount of time for sterilization, not 200°F.
C. Using a ballpoint pen to label contents: It is not advisable to use a ballpoint pen for labeling sterilized items because ink might not withstand the autoclave's high temperatures. Permanent markers or labels that can endure high temperatures should be used.
D. Stacking wrapped packages tightly into the autoclave: Items should be arranged in a way that allows steam to circulate freely, so tightly stacking packages can hinder proper sterilization.

Correct Answer is B

Explanation

A. Wipe away the first five drops of blood after puncturing: Only the first drop of blood should be wiped away to remove any tissue fluid, not the first five drops.
B. Apply even pressure to the finger during the collection: Applying even pressure helps to promote blood flow without causing hemolysis or excessive squeezing, which could affect test results.
C. Puncture the index finger at the tip: The recommended site for a capillary puncture is the side of the middle or ring finger, not the tip of the index finger.
D. Puncture parallel to the fingerprint: The puncture should be made perpendicular to the fingerprint ridges to ensure an adequate blood flow and reduce the risk of blood running along the ridges.
