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 ["B","C","D","F"]

Explanation

Choice A rationale
It is a common misconception that something should be placed in the mouth of someone having a seizure to prevent them from biting their tongue. However, this can cause more harm than good, including injury to the person’s mouth or the rescuer’s fingers.
Choice B rationale
Moving furniture away from the person having a seizure can help prevent injury. During a seizure, a person may move uncontrollably, and removing nearby objects can reduce the risk of harm.
Choice C rationale
Loosening constrictive clothing can help the person breathe more easily during and after a seizure.
Choice D rationale
Providing privacy can help maintain the person’s dignity and reduce embarrassment after a seizure.
Choice E rationale
It is not recommended to restrain a person during a seizure. This can result in injury. Instead, the goal is to keep the person safe until the seizure stops on its own.
Choice F rationale

Positioning the person on their side with their head flexed forward can help prevent aspiration, which can occur if the person vomits during or after a seizure.

Correct Answer is ["0.9 "]

Explanation

Step 1: We are instructed to administer tobramycin 35mg IM every 8 hours. The available supply is 40mg in a 1 mL vial.

Step 2: We need to find out how many mL’s should the nurse administer. Step 3: We can set up a proportion to solve this.

Step 4: If 40mg is equivalent to 1mL, then 35mg is equivalent to x mL. Step 5: Solving for x gives us x = (35mg ÷ 40mg) × 1mL.

Step 6: Calculating the above expression gives us x = 0.875 mL.

Step 7: Rounding our answer to the nearest tenth, we get 0.9 mL. So, the nurse should administer 0.9 mL.
