A medical assistant is preparing to perform a bilateral ear irrigation on a patient. The assistant should inform the patient that they might experience which of th following discomforts during irrigation?
Vertigo
Urticaria
Edema
Rhinitis
The Correct Answer is A
A. Vertigo: Ear irrigation can sometimes lead to vertigo or dizziness because the procedure may disturb the balance mechanisms in the inner ear.
B. Urticaria: Urticaria (hives) is an allergic reaction and is not a typical response to ear irrigation.
C. Edema: Edema is not a common reaction to ear irrigation. The procedure is generally localized to the ear canal and should not cause swelling.
D. Rhinitis: Rhinitis involves inflammation of the nasal mucous membranes and is unrelated to ear irrigation.

Correct Answer is C
Explanation
A. Alternating current (AC) interference: AC interference is caused by electrical equipment near the EKG machine and appears as uniform, small, rapid spikes. It is not caused by patient movement.
B. Arrhythmia: An arrhythmia refers to an abnormal heart rhythm and is related to cardiac function, not patient movement.
C. Somatic tremor: Somatic tremor is caused by voluntary or involuntary muscle movement, such as a patient moving their arm, which creates artifact on the EKG tracing that appears as irregular, erratic spikes.
D. Interrupted baseline: An interrupted baseline occurs when the electrical connection is lost, often due to a lead falling off, not due to patient movement.
Correct Answer is C
Explanation
A. 99.6°F: This temperature is higher than expected for an axillary reading. Axillary temperatures are generally lower than oral temperatures.
B. 98.6°F: This reading matches the oral temperature. However, axillary temperatures are usually lower by approximately 1°F compared to oral temperatures.
C. 97.6°F: This is the correct answer because axillary temperatures tend to be about 1°F lower than oral temperatures.
D. 96.6°F: This reading is lower than typically expected for an axillary temperature and would indicate hypothermia, which is not expected if the oral temperature was normal.
