Explanation
A. "Avoid alcohol for 48 hours prior to the test.": While avoiding alcohol may be generally recommended for some tests, fasting is the primary requirement for a glucose tolerance test (GTT).
B. "Do not eat for 8 hours prior to the test.": A GTT typically requires fasting for 8-12 hours to accurately measure glucose levels.
C. "Limit physical exertion for 24 hours prior to the test.": Physical exertion is not typically a specific concern for a GTT, but fasting is essential.
D. "Eat a high carbohydrate meal 3 hours prior to the test.": A high carbohydrate meal is not required; fasting is necessary before the test.
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.
