Ch-56, 57, 58 Dermatologic/opthalmic/otic Drugs

Question 1

What kind of drugs decrease intra ocular pressure?

Answer 1

Cholinergics, adrenergics, beta adrenergic blockers, carbonic a hydrate inhibitors, osmotic diuretics, prostaglandin agonists

Question 2

Cholinergic drugs are also known as what for ophthalmic drugs?

Answer 2

Miotics

Question 3

What are the action of miotics(cholinergic drugs) as an optical in drug?

Answer 3

Cause miosis or pupillary constriction dilating the pupils

Question 4

How does giving a cholinergic drug decrease intra ocular pressure?

Answer 4

Cholinergics cause contraction of pupils causing vasodilation widening the space where the aqueous humor can drain

Question 5

Sympathomimetics (adrenergic) drugs are also called what as ophthalmic drugs?

Answer 5

Mydriatics

Question 6

What are the actions of mydriatics (Sympathomimetics/adrenergics) ?

Answer 6

Stimulation of alpha and/or beta 2 ocular receptors to dilate pupils

Question 7

When alpha receptors are activated by mydriatics what do they do for intra ocular pressure?

Answer 7

Dilate pupils increasing the outflow of aqueous humor

Question 8

When beta 2 receptors are activated by mydriatics what happens to the intra ocular pressure?

Answer 8

Ocular vasodilation occurs preventing too much production of aqueous humor

Question 9

Carbonic anhydrase inhibitors do what for intra ocular pressure?

Answer 9

Inhibit enzyme carbonic anhydrase resulting in decreased intra ocular pressure

Question 10

What condition would you use carbonic anhydrase inhibitors for?

Answer 10

Management of glaucoma

Question 11

What should you be careful of before administering carbonic anhydrase inhibitors?

Answer 11

Make sure the patient does not have a sulfa allergy as they are related

Question 12

Osmotic diuretics do what to alter intra ocular pressure?

Answer 12

Pulls excess fluid from the eye back into blood vessels balancing out the pressure

Question 13

What kind of patients should stay away from osmotic diuretics drugs?

Answer 13

Patients with kidney failure, someone who is dehydrated, someone with heart failure

Question 14

The nurse is assessing skin of a patient using benzoyl peroxide for 2 weeks as a treatment for acne. What side effect will show he is having an allergic reaction?

Answer 14

Blistering skin over the treatment area

Question 15

Answer 16

Itching and burning

Question 17

When the nurse is teaching a patient about the mechanism of action if tretinoin what statement by the nurse is true?

Answer 17

This medication actually causes skin peeling

Question 18

The ophthalmologist has given a patient a dose of ocular atropine drops before an eye exam. What are the reason for the drops?

Answer 18

These drops will cause your pupils to dilate which makes the eye exam easier

Question 19

When assessing a patient who is receiving a direct acting cholinergic eye drop as part of treatment for glaucoma the nurse anticipates the he drug affects the pupil in what way?

Answer 19

It causes miosis or pupil constriction

Question 20

During patient teaching regarding self administration of ophthalmic drops what statement is true?

Answer 20

Be sure to place the drops in the conjunctival sac of the lower eyelid

Question 21

When the nurse is providing teaching about eye medication for glaucoma the nurse tells the patient miotics help glaucoma by what mechanism of action?

Answer 21

Decreasing intra ocular pressure

Question 22

During the assessment of a glaucoma patient who has newly prescribed carbonic anhydrase inhibitor eye drops the nurse would report a history of what condition?

Answer 22

Allergy to sulfa drugs

Question 23

A patient has undergone eye procedure during which ophthalmic mydriatics and anesthetic drops were used. The nurse gives what instructions to the patient?

Answer 23

Do not rub or touch the numb eye, be sure to wear sunglasses before you go outside, report any increase in eye pain or drainage to the doctor

Question 24

The nurse is administering Sympathomimetic ophthalmic drops. What therapeutic effect will the eye drops have on the patient?

Answer 24

Reduced intra ocular pressure
