While performing a blood culture venipuncture, a medical assistant cleanses a patient's skin with isopropyl alcohol. Which of the following actions is the next step?
Cleanse the site with chlorhexidine.
Prepare a wet mount slide.
Confirm the patient's blood type.
Obtain the patient's temperature.
The Correct Answer is A
A. Cleanse the site with chlorhexidine. After cleaning with isopropyl alcohol, the site should be cleansed with chlorhexidine to ensure the skin is sterile, reducing the risk of contamination in the blood culture.
B. Prepare a wet mount slide. Preparing a wet mount slide is unrelated to blood culture venipuncture and would not be the next step in this procedure.
C. Confirm the patient’s blood type. Confirming blood type is not part of the blood culture process and is not relevant at this stage.
D. Obtain the patient’s temperature. While monitoring the patient’s temperature might be necessary for diagnostic purposes, it is not the next step in performing a blood culture venipuncture.
