The patient with glaucoma is usually started on the lowest dose of medication. Which of the following is the preferred initial ophthalmic medication?

Choice A rationale

While prothrombin level is an important test in evaluating blood clotting disorders, it is not typically used in the initial diagnostic evaluations for a cerebrovascular accident (CVA) or stroke.
Choice B rationale
Brain CT or MRI scans are commonly used in the initial diagnostic evaluations for a CVA. These imaging tests can show bleeding in the brain, an ischemic stroke, a tumor, or other conditions.
Choice C rationale
A chest x-ray is not typically used in the initial diagnostic evaluations for a CVA. It is more commonly used to diagnose conditions affecting the lungs and heart.
Choice D rationale
A lumbar puncture, or spinal tap, may be used in some cases to help diagnose a CVA, but it is not typically part of the initial diagnostic evaluations.

Choice C rationale
When providing care for a comatose patient, a nurse should evaluate motor responses by observing the patient’s response to painful stimuli. This can be done by applying a painful stimulus, such as a trapezius pinch or nailbed pressure, and observing the patient’s motor response. Purposeful or semi-purposeful movements, such as localizing or withdrawing from pain, can provide valuable information about the patient’s level of consciousness and neurological function.
Choice A rationale
The Romberg test is used to evaluate balance and is not typically used to evaluate motor responses in a comatose patient.
Choice B rationale
Assessing the patient’s sensitivity to temperature and touch can provide information about sensory function, but it does not directly evaluate motor responses.
Choice D rationale

Observing the reaction of pupils to light can provide information about cranial nerve function, but it does not directly evaluate motor responses.
