28. Which of the following actions should a clinical medical assistant take when performing an eye Irrigation?
Allow the solution to flow from the inner to the outer canthus.
Fill the syringe with 10 mL of the irrigating solution.
Don powdered gloves.
Direct the Irrigation solution toward the cornea.
The Correct Answer is A
A. Allow the solution to flow from the inner to the outer canthus: This technique helps to flush out debris and contaminants while avoiding the spread of the solution into the unaffected eye.
B. Fill the syringe with 10 mL of the irrigating solution. The volume of the irrigating solution may vary, but 10 mL is not a standard quantity; the key is ensuring adequate flushing.
C. Don powdered gloves: Powdered gloves can cause irritation; non-powdered gloves are recommended for eye irrigation.
D. Direct the irrigation solution toward the cornea: The solution should not be directed toward the cornea to avoid damage; it should flow gently across the eye.

Correct Answer is A
Explanation
A. Ensure the otoscope is in the room. Ensuring that the otoscope and other necessary equipment are in the room is an important step in preparing the room for a physical examination.
B. Replace the half-full sharps containers. Sharps containers should be replaced when they are three-quarters full, not necessarily when they are half-full. This action, while important, is not specific to preparing for a general physical examination.
C. Obtain preauthorization from insurance. Preauthorization is an administrative task that is not directly related to preparing an examination room.
D. Sterilize counter surfaces in the room. Cleaning and disinfecting counter surfaces is important for infection control but typically would have been done after the last patient. This action is less directly related to preparing for a general physical exam compared to ensuring the necessary equipment is present.
Correct Answer is C
Explanation
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.
