A client with open-angle glaucoma is using pilocarpine ophthalmic solution, a miotic agent. Which action should the nurse at the eye clinic include in evaluating the effectiveness of the medication?

Use Snellen chart to assess visual acuity.

Check amount of drainage from each eye.

Palpate eyelids for decreased swelling.

Review eye pressure measurements.

Answer and Explanation

The Correct Answer is D

Choice A reason: Using a Snellen chart to assess visual acuity is not a direct measure of the effectiveness of pilocarpine, which is used to lower intraocular pressure by constricting the pupil and increasing aqueous humor outflow. Visual acuity may be affected by other factors, such as refractive errors, cataracts, or macular degeneration.

Choice B reason: Checking the amount of drainage from each eye is not a relevant action for evaluating the effectiveness of pilocarpine, which does not affect tear production or drainage. Excessive or abnormal eye drainage may indicate an infection, allergy, or injury.

Choice C reason: Palpating the eyelids for decreased swelling is not a useful action for evaluating the effectiveness of pilocarpine, which does not cause or reduce eyelid swelling. Eyelid swelling may be caused by inflammation, infection, allergy, or trauma.

Choice D reason: Reviewing eye pressure measurements is the correct action for evaluating the effectiveness of pilocarpine, which is used to lower intraocular pressure in patients with open-angle glaucoma. High intraocular pressure can damage the optic nerve and cause vision loss. Pilocarpine reduces intraocular pressure by constricting the pupil and increasing aqueous humor outflow.

Correct Answer is []

Explanation

Potential Condition:Methemoglobinemia

Methemoglobinemia is a condition in which the hemoglobin in the blood is unable to bind oxygen effectively, resulting in tissue hypoxia. It can be caused by exposure to certain drugs or chemicals, such as nitrates, benzocaine, or dapsone. Some symptoms of methemoglobinemia include cyanosis, headache, fatigue, dyspnea, and tachycardia. In severe cases, it can lead to seizures, coma, and death.

Actions to Take:

Draw blood for a complete blood count
administer methylene blue

A complete blood count (CBC) can help diagnose methemoglobinemia by measuring the level of methemoglobin in the blood. A normal level is less than 1%, while a level above 15% can cause symptoms. A level above 30% can be life-threatening. Methylene blue is a medication that can reduce methemoglobin back to normal hemoglobin and restore oxygen delivery to the tissues. It is given intravenously at a dose of 1-2 mg/kg over 5 minutes.

Parameters to Monitor:

Methemoglobin level
heart rate and rhythm

The methemoglobin level is the most important parameter to monitor in methemoglobinemia, as it indicates the severity of the condition and the response to treatment. The goal is to lower the level below 10% or until symptoms resolve. The heart rate and rhythm are also important to monitor, as methemoglobinemia can cause tachycardia and dysrhythmias due to hypoxia and acidosis. The goal is to maintain a normal sinus rhythm and a heart rate within the normal range for the client’s age and condition.

Correct Answer is ["167"]

Explanation

To find the answer, we can use the following formula:

(mL of fluid / hours of infusion) = mL/hr

Substituting the values from the question, we get:

(500 mL / 3 hours) = 166.67 mL/hr

Rounding to the nearest whole number, we get 167 mL/hr.

Therefore, the nurse should program the infusion pump to deliver 167 mL/hr of dextrose in 5% water IV.
