Which of the following artifacts may occur if a patient is talking during an EKG?
Alternating current
Interrupted baseline
Somatic tremor
Wandering baseline
The Correct Answer is C
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.

Correct Answer is D
Explanation
A. The patient reports the receptionist was rude to them. This is not relevant to the patient’s medical care and should not be documented in the health record.
B. The patient states that there is an error on their bill. Billing issues are not related to the clinical care of the patient and should not be documented in the health record.
C. The patient states their insurance might be changing soon. This is administrative information and does not pertain to the clinical aspect of the patient’s care.
D. The patient reports they recently developed a strawberry allergy. This is relevant medical information that could affect the patient’s treatment and should be documented in the health record.
Correct Answer is A
Explanation
A. Pull the lower eyelid down. Pulling the lower eyelid down creates a pocket for the drops, making it easier to administer them without contacting the eye’s surface directly.
B. Have the patient open their eye using both hands: Using both hands to open the eye may be uncomfortable and unnecessary; the assistant should guide the patient gently.
C. Use a retractor on the eye before administering the drops: Retractors are not typically used for eye drop administration; this can cause discomfort and is not standard practice.
D. Hold the dropper 1 inch away from the surface of the eye: The dropper should be held close enough to the eye to avoid contaminating the eye surface or the dropper, but not so close as to touch the eye.
