Begin audiometer testing using both ears.
Use the Ishihara test to measure the patient's field of vision.
Document any squinting during the Snellen test.
The Correct Answer is D
A. Begin audiometer testing on the highest frequency and lower gradually: Audiometer testing should begin at lower frequencies and gradually increase to ensure a thorough evaluation of hearing.
B. Begin audiometer testing using both ears: Audiometer testing is usually done one ear at a time to accurately assess hearing in each ear.
C. Use the Ishihara test to measure the patient's field of vision: The Ishihara test is used for color vision testing, not for measuring the field of vision.
D. Document any squinting during the Snellen test: Squinting during the Snellen test can indicate vision problems and should be documented as it may affect the accuracy of the vision assessment.

A. Place a pulse oximeter on the patient's earlobe: A pulse oximeter measures oxygen saturation and pulse but is not used for manually palpating the pulse.
B. Palpate the patient's radial artery: The radial artery, located at the wrist, is commonly palpated to manually obtain the pulse.
C. Place a pulse oximeter on the patient's finger: A pulse oximeter measures pulse rate and oxygen saturation but does not involve manual palpation.

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.
