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 C
Explanation
A. Alternating current: Alternating current interference is due to electrical equipment, not patient movement or talking.
B. Interrupted baseline: An interrupted baseline occurs when there is a break in the electrical connection, often due to a loose lead, not because of patient talking.
C. Somatic tremor: Somatic tremor can occur due to muscle movement, including that caused by talking. This can result in erratic, uneven spikes on the EKG tracing.
D. Wandering baseline: A wandering baseline is usually caused by improper electrode placement or poor skin contact, not talking. However, excessive movement, including deep breaths or large chest movements during talking, can contribute to a wandering baseline.
