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 B
Explanation
A. Implied consent: Implied consent is typically used in emergency situations where verbal or written consent cannot be obtained and is not suitable for elective procedures like a colonoscopy.
B. Informed consent: For a colonoscopy, which is an invasive procedure, informed consent is required. This involves providing the patient with detailed information about the procedure, its risks, benefits, and alternatives.
C. Prior authorization: Prior authorization is related to insurance coverage and is not typically obtained by the medical assistant; it is usually handled by the billing department or insurance coordinator.
D. Immunization records: Immunization records are not required for a colonoscopy; they are more relevant for vaccinations and certain other procedures.
Correct Answer is B
Explanation
A. Negotiate with insurance companies for increased reimbursement. Negotiating with insurance companies is typically not a responsibility of a medical assistant within a PCMH.
B. Communicate with a nurse coordinator for transportation needs. This is correct. In a PCMH model, medical assistants may coordinate with other members of the healthcare team, including nurse coordinators, to address various patient needs, including transportation.
C. Schedule admissions to a facility. While scheduling may be part of a medical assistant’s duties, it is not specific to the PCMH model.
D. Focus strictly on the course of treatment. The PCMH model involves a holistic approach to patient care, not just focusing on treatment. It includes coordination of care, addressing social determinants of health, and ensuring continuity of care.
