Question 1

Which medications are appropriate for minor irritation and injury? (Select all that apply.)Note: Credit will be given only if all correct choices and no incorrect choices are selected.

Accepted Answer

A,C,D

Question 2

The client has been prescribed travoprost (Travatan).When does the nurse anticipate the maximum effect of this medication occurs?

Accepted Answer

Travoprost (Travatan) is a prostaglandin analog used in the treatment of glaucoma. Its maximum effect on reducing intraocular pressure typically occurs around 12 hours after administration.

Question 3

In the anterior chamber of the eye,what is the medical term for the watery fluid that is found here?

Accepted Answer

The watery fluid found in the anterior chamber of the eye is called the aqueous humor. It helps to maintain intraocular pressure and provides nutrients to the avascular structures of the eye.

Question 4

To prevent systemic absorption of timolol (Timoptic),what administration instructions are appropriate for the nurse to include in the teaching?

Accepted Answer

Applying pressure over the lacrimal sac for 1 minute helps to prevent the systemic absorption of the medication by occluding the nasolacrimal duct, reducing the amount of drug that can be absorbed into the systemic circulation.

Question 5

A client has been prescribed latanoprost (Xalatan).The nurse informs the client regarding potential side effects.Which side effect is not appropriate for the nurse to include in the client teaching?

Accepted Answer

Latanoprost (Xalatan) is known to cause increased pigmentation of the iris, not decreased pigmentation. Other side effects can include dryness and photophobia.

Question 6

A client has been prescribed timolol (Timoptic).When does the maximum therapeutic effect occur for the medication?

Accepted Answer

Timolol is a beta-blocker that is used to treat glaucoma. It takes 2-4 weeks for the maximum therapeutic effect to occur.

Question 7

The client asks the nurse which OTC medication will lubricate the eye and cause vasoconstriction.Which response by the nurse is correct?

Accepted Answer

Oxymetazoline (OcuClear) is an over-the-counter medication that causes vasoconstriction and can be used in the eye for redness relief. The other options do not offer both lubrication and vasoconstriction.

Question 8

The nurse is caring for a client who is diagnosed with glaucoma.The client wants to know why this condition can lead to blindness.What is the best response by the nurse?

Accepted Answer

Glaucoma leads to increased intraocular pressure, which can damage the optic nerve over time, potentially leading to blindness.

Question 9

Following an extensive eye examination where a mydriatic agent was utilized,which nursing diagnosis is most appropriate for the client?

Accepted Answer

Mydriatic agents dilate the pupils, which can temporarily impair vision and increase the risk of injury due to visual acuity deficits.

Question 10

The nurse is providing education to a client with a history of earwax buildup.Which medication does the nurse include in the teaching session?

Accepted Answer

Carbamide peroxide (Debrox) is commonly used to soften and remove earwax. It works by releasing oxygen when it comes into contact with earwax, which breaks down the wax, making it easier to remove.

Question 11

The nurse is caring for a client with closed-angle glaucoma.What are the characteristics of this disorder the nurse must be aware of when providing care? (Select all that apply.)Note: Credit will be given only if all correct choices and no incorrect choices are selected.

Accepted Answer

The answer of The nurse is caring for a client...

Question 12

What instructions are appropriate for the nurse to include when teaching a client ways to prevent "swimmer's ear"?

Accepted Answer

Application of 2% acetic acid to the ear canal after swimming can help prevent swimmer's ear by creating an acidic environment that inhibits bacterial growth.

Question 13

What is the most appropriate explanation as to why dipivefrin hydrochloride (Propine)effectively decreases intraocular pressure?

Accepted Answer

Dipivefrin hydrochloride (Propine) is a prodrug that is converted to epinephrine in the eye. Epinephrine increases the outflow of aqueous humor, which effectively decreases intraocular pressure.

Question 14

Which medication does the nurse anticipate for a client who will undergo an ophthalmic examination?

Accepted Answer

Cycloplegics and mydriatics are commonly used in ophthalmic examinations to dilate the pupil and temporarily paralyze the ciliary muscle, allowing for a thorough examination of the eye.

Question 15

Which medications increase the outflow of aqueous humor? (Select all that apply.)Note: Credit will be given only if all correct choices and no incorrect choices are selected.

Accepted Answer

Miotics, sympathomimetics, and prostaglandins increase the outflow of aqueous humor, helping to lower intraocular pressure in conditions like glaucoma. Beta blockers and calcium channel blockers primarily decrease aqueous humor production.

Question 16

The nurse is caring for a client with open-angle glaucoma.What are the characteristics of this disorder the nurse must be aware of when providing care? (Select all that apply.)Note: Credit will be given only if all correct choices and no incorrect choices are selected.

Accepted Answer

Open-angle glaucoma is the most common type of glaucoma, characterized by a slow increase in intraocular pressure, and the iris does not cover the trabecular meshwork, allowing fluid to drain slowly.

Question 17

The client complains of blurry vision after using pilocarpine (Isopto Carpine).Which explanation about the blurry vision is most appropriate by the nurse?

Accepted Answer

Pilocarpine is a cholinergic medication used to treat glaucoma by reducing intraocular pressure. Blurry vision is a common side effect due to its action on the eye muscles but typically is temporary as the body adjusts to the medication.

Question 18

The nurse is reviewing a medication administration record.Which medication from the list is considered a mydriatic agent?

Accepted Answer

Phenylephrine (Neo-Synephrine) is a mydriatic agent used to dilate the pupils.

Question 19

Which medications decrease the formation of aqueous humor? (Select all that apply.)Note: Credit will be given only if all correct choices and no incorrect choices are selected.

Accepted Answer

The answer of Which medications decrease the formation of aqueous...

Question 20

The client has been diagnosed with acute glaucoma.What are the common causes for this condition?

Accepted Answer

Acute glaucoma can be caused by trauma or hemorrhage, which can lead to a sudden increase in intraocular pressure.
