A client is receiving pilocarpine hydrochloride ophthalmic drops for glaucoma. The client calls the clinic nurse and reports difficulty seeing at night. Which explanation should the nurse provide?

The drops increase the fluid in the eyes and cloud the visual field.

The eye drops slow pupil response to accommodate for darkness.

The medication can cause the lens to become more opaque.

The medication causes pupils to dilate, which reduces night vision.

Answer and Explanation

The Correct Answer is B

Choice A reason: While pilocarpine ophthalmic drops can cause increased fluid in the eyes to help manage glaucoma, they do not typically cloud the visual field. The main purpose of pilocarpine is to reduce intraocular pressure by increasing the outflow of aqueous humor.

Choice B reason: Pilocarpine is a cholinergic agent that stimulates the sphincter muscles of the iris, leading to miosis (constriction of the pupil). This reduces the pupil's ability to dilate in low-light conditions, making it more difficult for clients to see in the dark. This explanation accurately addresses the client's concern about night vision.

Choice C reason: Pilocarpine does not cause the lens to become more opaque. Opaque lenses are more commonly associated with cataracts, which are not related to the use of pilocarpine.

Choice D reason: Pilocarpine causes the pupils to constrict (miosis) rather than dilate. This constriction affects the pupil's ability to adapt to darkness but does not cause dilation that reduces night vision.

Correct Answer is A

Explanation

Choice A reason: Feverfew can interact with aspirin or NSAIDs, potentially increasing the risk of bleeding. This information is crucial for clients to avoid adverse interactions.

Choice B reason: While increased anxiety and nervousness have been reported, these side effects are less critical compared to the potential for harmful drug interactions.

Choice C reason: Those with allergies to chamomile, ragweed, or yarrow should avoid feverfew, but the primary concern should be potential drug interactions.

Choice D reason: Gastrointestinal side effects such as abdominal pain, gas, nausea, vomiting, and diarrhea are important to note, but they do not pose as immediate a risk as the potential for drug interactions.

A. Instruct the client to take the two medications at least two hours apart. B. Advise the client that the birth control pills will be less effective while taking doxycycline hyclate. C. Encourage the client to stop taking birth control pills until she has finished taking all the doxycycline hyclate. D. Notify the healthcare provider of the contraindication to tetracyclines.

Correct Answer is B

Explanation

Choice A reason: Instructing the client to take the medications two hours apart does not prevent the interaction that reduces the effectiveness of birth control pills when taken with doxycycline.

Choice B reason: It is important to advise the client that doxycycline can reduce the effectiveness of birth control pills. The client should be encouraged to use additional forms of contraception to prevent unintended pregnancy.

Choice C reason: Stopping birth control pills is not necessary; instead, the client should be informed about the interaction and the need for additional contraception.

Choice D reason: While notifying the healthcare provider of potential contraindications is good practice, it does not provide immediate guidance to the client on how to manage the interaction between doxycycline and birth control pills.
