When measuring distance visual acuity, the medical assistant should instruct the patient to do which of the following?
Stand 25 feet from the Snellen chart.
Allow them to squint if necessary.
Keep both eyes open while using the occluder.
Start with the bottom line of the Snellen chart and work upward.
The Correct Answer is C
A. Stand 25 feet from the Snellen chart. The standard distance for testing visual acuity with a Snellen chart is 20 feet, not 25 feet. Testing at 25 feet would not provide accurate results.
B. Allow them to squint if necessary. Squinting can artificially improve vision, leading to inaccurate results. The patient should be instructed to avoid squinting during the test.
C. Keep both eyes open while using the occluder. The patient should use the occluder to cover one eye but keep both eyes open during the test. This ensures that each eye is tested individually without any pressure or distortion from closing the other eye.
D. Start with the bottom line of the Snellen chart and work upward. The patient should start from the top of the Snellen chart and work downward. Starting from the bottom would likely result in frustration and inaccurate assessment as the lines become increasingly difficult.

Correct Answer is A
Explanation
A. Support group: A support group can provide emotional support, information, and shared experiences relevant to managing a new medical diagnosis.
B. Department of Social Services: While the Department of Social Services may assist with various needs, such as financial or housing assistance, it is not specifically focused on the emotional and informational support for a new diagnosis.
C. Food bank: A food bank is primarily for food distribution and would not directly address the challenges of managing a new medical diagnosis.
D. Local department of health: Although the local department of health may provide resources or referrals, a support group would be more focused on the emotional and practical aspects of dealing with a new diagnosis.
Correct Answer is B
Explanation
A. Place a bandage on the site after holding pressure for 1 min: While a bandage may be used, holding pressure for 1 minute is excessive. Typically, pressure is held for a shorter period to control bleeding.
B. Apply direct, firm pressure to the puncture site on the finger: Applying firm pressure helps to stop bleeding after the puncture and is the appropriate technique.
C. Warm the site for a minimum of 10 min prior to puncture. Warming the site is usually done for a few minutes (not 10) to increase blood flow, but it should be done briefly and not excessively.
D. Have the parent hold the child during the procedure: While it’s important to ensure the child is held securely, the parent should assist by holding the child gently but not to the extent that it interferes with the procedure.
