Squeeze the site gently to obtain a blood droplet.

Allow the site to dry.

Apply blood to the test strip.

Cleanse the site with an antiseptic swab.

Pierce the puncture site quickly.

Answer and Explanation

The Correct Answer is D,B,E,A,C

Choice D rationale

Cleansing the site with an antiseptic swab reduces the risk of infection by removing surface bacteria and contaminants. It is essential to prepare the site adequately for a clean puncture.

Choice B rationale

Allowing the site to dry prevents the antiseptic from diluting the blood sample and ensures accurate readings. Moisture at the puncture site can interfere with the effectiveness of the glucose meter.

Choice E rationale

Piercing the puncture site quickly minimizes discomfort for the client and ensures a clean puncture. A swift puncture reduces the risk of the site becoming overly irritated or bruised.

Choice A rationale

Squeezing the site gently helps to obtain an adequate blood sample without causing excessive damage to the surrounding tissue. It ensures a sufficient droplet size for testing without causing additional trauma.

Choice C rationale

Applying blood to the test strip allows the glucose meter to measure the blood glucose level accurately. It is the final step in obtaining a capillary blood sample for testing. .

Correct Answer is A

Explanation

Choice A rationale

Increasing fluid intake helps flush out the barium contrast from the body to prevent constipation and promote bowel movements.

Choice B rationale

Over-the-counter antidiarrheal medications are not appropriate because barium can cause constipation, not diarrhea.

Choice C rationale

Barium contrast does not cause black, tarry stools. Instead, it causes stools to be white or light-colored.

Choice D rationale

Following a low-fiber diet is not recommended after a barium contrast study. High-fiber foods help facilitate bowel movements.
