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.
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 D
Explanation
Choice A reason: Expectorating bronchial secretions is not an assessment information that indicates that the antitussive medication benzonatate is effective. Benzonatate is a medication that suppresses the cough reflex by numbing the throat and lungs. It does not loosen or thin the mucus in the airways, which would facilitate expectoration.
Choice B reason: Reports reduced nasal discharge is not an assessment information that indicates that the antitussive medication benzonatate is effective. Benzonatate is a medication that suppresses the cough reflex by numbing the throat and lungs. It does not affect the production or drainage of nasal secretions, which are caused by inflammation and infection in the upper respiratory tract.
Choice C reason: Able to sleep through the night is not an assessment information that indicates that the antitussive medication benzonatate is effective. Benzonatate is a medication that suppresses the cough reflex by numbing the throat and lungs. It does not have any sedative or hypnotic effects, which would promote sleep. However, by reducing coughing, benzonatate may indirectly improve the quality of sleep for the client.
Choice D reason: Denies having coughing spells is an assessment information that indicates that the antitussive medication benzonatate is effective. Benzonatate is a medication that suppresses the cough reflex by numbing the throat and lungs. It reduces the frequency and intensity of coughing, which can relieve discomfort and irritation for the client.
Correct Answer is ["0.8"]
Explanation
The correct answer is 0.8 mL.
To find the answer, we can use the following formula:
(mg of medication ordered / mg of medication per mL) = mL to administer
Substituting the values from the question, we get:
(80 mg / 60 mg per 0.6 mL) = 0.8 mL
Therefore, the nurse should administer 0.8 mL of enoxaparin sodium injection.
