Which of the following instructions should a medical assistant give to a patient who is scheduled for a GTT?
"Avoid alcohol for 48 hours prior to the test."
"Do not eat for 8 hours prior to the test."
"Limit physical exertion for 24 hours prior to the test."
"Eat a high carbohydrate meal 3 hours prior to the test."
The Correct Answer is B
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 A
Explanation
A. Near visual acuity: Hyperopia, or farsightedness, affects the ability to see objects up close. Testing near visual acuity assesses how well a patient can see objects at a close range.
B. Ishihara: The Ishihara test is used for detecting color vision deficiencies, not hyperopia.
C. Snellen chart: The Snellen chart tests distance vision and is more useful for assessing nearsightedness (myopia) rather than farsightedness (hyperopia).
D. Tonometry: Tonometry measures intraocular pressure to assess for glaucoma, not hyperopia.
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.
