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

Carbonic anhydrase inhibitors

Prostaglandins

Alpha-agonists

Beta-blockers

Answer and Explanation

The Correct Answer is B

The correct answer is: = b. Prostaglandins

Choice A: Carbonic anhydrase inhibitors: These medications can be used for glaucoma, but they are not typically the first-line treatment due to potential side effects.

Choice B: Prostaglandins (Correct Answer) These are often the preferred initial medication for glaucoma because they are effective at lowering eye pressure, have minimal systemic side effects, and are typically used once daily.

Choice C: Alpha-agonists: These medications can be used as an adjunct to other glaucoma medications but are not usually the first choice due to potential side effects like dry mouth and fatigue.

Choice D: Beta-blockers: While once a common first-line treatment, beta-blockers have been largely replaced by prostaglandins due to potential side effects like slowed heart rate and worsened breathing problems.

Correct Answer is A

Explanation

Choice A rationale
If a patient is suspected of having meningitis, the provider will likely prescribe antibiotic therapy after reviewing the lab results. Meningitis is often caused by a bacterial infection, and antibiotics are the primary treatment. The specific antibiotic prescribed will depend on the type of bacteria causing the infection.
Choice B rationale
Antiemetics are medications that help prevent and treat nausea and vomiting. They are not typically used as the primary treatment for meningitis.
Choice C rationale

Analgesics are medications that relieve pain. While they may be used to help manage symptoms in a patient with meningitis, they are not used to treat the underlying infection.
Choice D rationale
Antiviral therapy may be used if the meningitis is caused by a viral infection. However, most cases of meningitis are caused by bacteria, and antibiotics are the primary treatment.

A. Prothrombin level B. Brain CT or MRI C. Chest x-ray D. Lumbar puncture

Correct Answer is B

Explanation

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.
