Which of the following techniques should a medical assistant use when inserting a needle for venipuncture?
Bevel up with a 45° angle
Bevel down with a 45° angle
Bevel up with a 15° angle
Bevel down with a 15° angle
The Correct Answer is C
A. Bevel up with a 45° angle: A 45° angle is too steep for venipuncture; this angle is typically used for intramuscular injections.
B. Bevel down with a 45° angle: Bevel down is incorrect for venipuncture as it increases the risk of the needle piercing through the vein.
C. Bevel up with a 15° angle: This is the correct technique for venipuncture. The needle should be inserted at a 15° to 30° angle, with the bevel facing up to ensure smooth entry into the vein and minimize discomfort.
D. Bevel down with a 15° angle: Bevel down is not recommended for venipuncture because it can cause the needle to catch on the vein wall, increasing the risk of injury or complications.

Correct Answer is A
Explanation
A. Place the arm electrodes facing downward. The arm electrodes should be placed with the tabs facing downward to reduce the risk of artifacts on the EKG tracing caused by movement or improper lead contact.
B. Place the electrodes over bony prominences when possible. Electrodes should not be placed over bony prominences, as this can interfere with the accuracy of the EKG reading. Instead, they should be placed on soft tissue.
C. Place the leg electrodes downward. Leg electrodes should also be placed with the tabs facing downward to prevent artifacts, similar to the arm electrodes.
D. Place the chest electrodes in a straight line just below the nipple. Chest electrodes should be placed according to specific anatomical landmarks, not in a straight line, to ensure accurate heart rhythm tracing.
Correct Answer is D
Explanation
A. Attention line: The attention line directs the letter to a specific person or department and does not serve as a greeting.
B. Inside address: The inside address includes the recipient’s address and is placed before the salutation but does not serve as a greeting.
C. Signature block: The signature block is where the sender signs the letter and provides their name and title, not the greeting.
D. Salutation: The salutation is the part of the letter where the writer greets the recipient, such as “Dear Dr. Smith,”.
