Question 1

What is the purpose of administering a cycloplegic agent? (Select all that apply.)

Accepted Answer

A,B,D

Question 2

Which medication is used to produce miosis following a diagnostic procedure?

Accepted Answer

Pilocarpine is a medication that is used to produce miosis following a diagnostic procedure. Miosis is the constriction of the pupil, and it can enhance visualization of certain structures within the eye during diagnostic procedures. Other medications listed (mannitol, atropine, and epinephrine) do not have a primary indication for producing miosis.

Question 3

What is the action of timolol maleate (Timoptic),a beta-adrenergic blocking agent?

Accepted Answer

Timolol maleate is a beta-adrenergic blocking agent that decreases the production of aqueous humor, which in turn helps to lower intraocular pressure in patients with glaucoma.

Question 4

The nurse is preparing a patient for an ophthalmic examination.Which action occurs when the nurse instills eyedrops to produce mydriasis?

Accepted Answer

Instilling eyedrops to produce mydriasis will result in extreme dilation of the pupil. This allows for better visualization of the internal structures of the eye during the ophthalmic examination.

Question 5

The nurse is assisting with applanation tonometry on a patient at the ophthalmologist's office.The results indicate the patient's reading to be 15 mm Hg.The nurse interprets this result as _____ IOP.

Accepted Answer

A reading of 15 mmHg is within the normal range for intraocular pressure (IOP) which is typically between 12-22 mmHg.

Question 6

A patient recently diagnosed with glaucoma is to begin drug therapy with carbonic anhydrase inhibitors.For which assessment(s)would the nurse need to contact the healthcare provider? (Select all that apply.)

Accepted Answer

The answer of A patient recently diagnosed with glaucoma is...

Question 7

The nurse is caring for a patient immediately following a right-sided trabeculectomy.When positioning this patient,the nurse will encourage a _____ position.

Accepted Answer

After a right-sided trabeculectomy, the patient should be positioned in a left side-lying position to promote drainage of intraocular fluid away from the surgical site. The prone position should be avoided to prevent pressure on the eye, and the right side-lying position may also put pressure on the surgical site. The Trendelenburg position is not indicated for this surgery.

Question 8

Which is a potential serious adverse effect associated with mannitol (Osmitrol)?

Accepted Answer

Mannitol is an osmotic diuretic that works by drawing fluid from the intracellular and extracellular spaces to the renal tubules to be excreted. This can lead to fluid overload, especially in patients with compromised cardiac or renal function. Bradycardia, anaphylaxis, and fever are not commonly associated with mannitol use.

Question 9

Which discharge instruction will the nurse include for a patient sent home from the clinic who is taking an adrenergic ophthalmic solution for an acute inflammation?

Accepted Answer

Adrenergic ophthalmic solutions can cause temporary blurred vision, so patients should avoid driving or operating machinery until their vision clears.

Question 10

What information will the nurse include when teaching the patient and family about postoperative care for a trabeculectomy? (Select all that apply.)

Accepted Answer

The answer of What information will the nurse include when...

Question 11

Which statement(s)about aqueous humor is/are true? (Select all that apply.)

Accepted Answer

Aqueous humor is a clear fluid that is produced by the ciliary body of the eye and circulates in the anterior chamber of the eye. It aids in maintaining the shape of the eyeball and providing nutrients and oxygen to various parts of the eye. Choice A is true because the aqueous humor bathes and feeds the lens, posterior surface of the cornea, and iris. Choice C is true because the aqueous humor drains out of the eye through drainage channels located near the junction of the cornea and sclera. Choice E is true because the aqueous humor flows out of the canal of Schlemm into the venous system of the eye. Choices B and D are false because aqueous humor does not play a role in maintaining iris color or manufacturing fluid for tear production.

Question 12

What information will the nurse include when instructing a patient on the correct method of instilling eyedrops? (Select all that apply.)

Accepted Answer

The answer of What information will the nurse include when...

Question 13

The nurse is educating a patient about a newly prescribed cholinergic agent.When relaying common adverse effects of this type of medication,the nurse will include information about: (Select all that apply.)

Accepted Answer

The answer of The nurse is educating a patient about...

Question 14

What is the mechanism of action of osmotic agents when used to decrease IOP?

Accepted Answer

Osmotic agents work by increasing plasma osmolarity, which draws fluid from the vitreous body of the eye into the bloodstream, thereby reducing intraocular pressure (IOP).

Question 15

Which type of medication would be used to dilate the pupils before an eye examination?

Accepted Answer

Adrenergic agents such as phenylephrine or tropicamide are commonly used to dilate the pupils for eye examinations.

Question 16

A factory worker had a chemical inadvertently splashed into his right eye.An eyewash was used at the work site.Which nursing assessment(s)would be important to include? (Select all that apply.)

Accepted Answer

Visual acuity should be assessed to determine any changes in vision. Presence of pain, blurred or halo vision, or lack of vision should be assessed to determine the severity of the injury. The type of chemical should be determined to guide treatment. Presence of contacts or use of eyeglasses should be assessed to determine if they need to be removed before flushing the eye. Presence of nystagmus is not directly related to eye splashes and is not a priority assessment.
