A medical assistant should administer which of the following examinations to a patient who has hyperopia?

A.

Near visual acuity

B.

Ishihara

C.

Snellen chart

D.

Tonometry

Answer and Explanation

The Correct Answer is A

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 D

Explanation

A. Soak the instrument in hot water: Hot water alone does not effectively sanitize instruments; proper sanitization typically requires cleaning agents and specific processes.
B. Rinse the instrument with a 10% bleach solution: While bleach is used for disinfection, it is not a step in the initial sanitization process.
C. Soak the instrument in a 70% isopropyl alcohol solution: Alcohol is used for disinfection rather than initial sanitization.
D. Rinse the instrument under running water: Rinsing the instrument under running water is a basic step in the sanitization process to remove visible debris before further cleaning and disinfection.

Correct Answer is B

Explanation

A. Sweating: Sweating is a normal physiological response to exercise and is not an indication to terminate the test.
B. Bradycardia: Bradycardia (abnormally slow heart rate) during an exercise stress test can indicate a serious problem and may require premature termination of the test.
C. Palpitations: Palpitations can occur during exercise, but they are not necessarily a reason to terminate the test unless accompanied by other symptoms or abnormalities.
D. Thirst: Thirst is not a contraindication for continuing an exercise stress test.
