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 A
Explanation
Choice A reason: Storing unused vials at room temperature is incorrect information that indicates a need for further education by the nurse, because somatropin is a growth hormone that should be stored in the refrigerator (2°C to 8°C) until use. Exposure to heat or light can degrade the medication and reduce its effectiveness.
Choice B reason: Rotating injection sites to minimize discomfort is correct information that does not indicate a need for further education by the nurse, because somatropin is administered subcutaneously and repeated injections at the same site can cause skin irritation, bruising, or infection.
Choice C reason: Discarding the medication if the solution is cloudy is correct information that does not indicate a need for further education by the nurse, because somatropin is a clear and colorless solution that should not be used if it appears cloudy, discolored, or contains particles. This may indicate contamination or degradation of the medication.
Choice D reason: Administering the medication subcutaneously is correct information that does not indicate a need for further education by the nurse, because somatropin is a growth hormone that is given by subcutaneous injection using a syringe or a pen device. Subcutaneous injection allows for better absorption and bioavailability of the medication.
Correct Answer is B
Explanation
Choice A reason: Hard candy can be used for a dry mouth, which is a common side effect of St. John's wort.
Choice B reason: Another form of contraception is needed, because St. John's wort can reduce the effectiveness of oral contraceptives and increase the risk of unplanned pregnancy. This information requires further instruction from the nurse.
Choice C reason: Insomnia may occur while taking the medication, which is another possible side effect of St. John's wort. The client should be advised to take the medication in the morning or afternoon, and avoid caffeine and alcohol.
Choice D reason: Sensitivity to the sun can develop, which is a rare but serious side effect of St. John's wort. The client should be instructed to wear sunscreen and protective clothing when exposed to sunlight.
