Begin audiometer testing using both ears.
Use the Ishihara test to measure the patient's field of vision.
Document any squinting during the Snellen test.
The Correct Answer is D
A. Begin audiometer testing on the highest frequency and lower gradually: Audiometer testing should begin at lower frequencies and gradually increase to ensure a thorough evaluation of hearing.
B. Begin audiometer testing using both ears: Audiometer testing is usually done one ear at a time to accurately assess hearing in each ear.
C. Use the Ishihara test to measure the patient's field of vision: The Ishihara test is used for color vision testing, not for measuring the field of vision.
D. Document any squinting during the Snellen test: Squinting during the Snellen test can indicate vision problems and should be documented as it may affect the accuracy of the vision assessment.

A. Capillary blood: Capillary blood can be used in some cases, especially in infants, but it is less accurate than arterial blood for measuring blood pH and gases.
B. Arterial blood: Arterial blood is the correct sample for measuring blood pH and gases (such as oxygen and carbon dioxide levels) because it reflects the gas exchange occurring in the lungs.
C. Venous blood: Venous blood is not typically used for measuring blood gases as it does not accurately reflect the oxygenation status of the body.
D. Cerebrospinal fluid: Cerebrospinal fluid is not used for measuring blood pH and gases; it is typically analyzed for conditions affecting the brain and spinal cord.
