The Correct Answer is A
A. Administering IV medication: Administering intravenous (IV) medication is typically within the scope of practice for registered nurses (RNs) due to the complexity and need for careful monitoring.
B. Performing a heel stick on an infant: This procedure is often performed by medical assistants, especially in a pediatric setting, as it is part of routine blood collection practices.
C. Drawing blood for a glucose tolerance test: Medical assistants are usually trained to perform blood draws, including for glucose tolerance tests.
D. Performing venipuncture with a winged collection device: Medical assistants are generally trained to perform venipunctures, including using winged collection devices (butterfly needles)

Correct Answer is B
Explanation
A. Prone: The prone position (lying face down) is not suitable for patients with labored breathing as it can restrict breathing further.
B. Fowler's: The Fowler's position (sitting upright or semi-upright) helps to ease breathing and is often used for patients experiencing shortness of breath or respiratory distress.
C. Supine: The supine position (lying flat on the back) may exacerbate breathing difficulties by increasing pressure on the chest.
D. Lithotomy: The lithotomy position (lying on the back with legs raised and spread) is used for specific procedures and is not appropriate for managing labored breathing.
Correct Answer is A
Explanation
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.
