Chapter 57 : Ophthalmic Drugs Questions
Question 1 of 5
The nurse is administering ophthalmic drops. Choose the action that should be performed first.
Correct Answer: D
Rationale: Before applying eye medications, clean any debris from the eye, if needed, and have the patient tilt the head back and look up at the ceiling. Drops are placed into the conjunctival sac, and then the eye is closed gently. Pressure may be applied to the inner canthus/lacrimal sac for 1 minute to reduce systemic absorption, and any excess medication can then be removed from around the eyes.
Question 2 of 5
The nurse is reviewing the medical record of a patient and notes an order for ophthalmic dexamethasone (Decadron) solution. The nurse knows that indications for ophthalmic dexamethasone include which conditions? (Select all that apply.)
Correct Answer: A,B,C,F
Rationale: Dexamethasone (Decadron) is used to treat inflammation of the eye, eyelids, conjunctiva, and cornea, and it may also be used in the treatment of uveitis, iridocyclitis, allergic conditions, and burns and in the removal of foreign bodies. It is not indicated for infections or glaucoma.
Question 3 of 5
A patient will be receiving mannitol, 1.5 g/kg IV 1 hour before ocular surgery. The patient weighs 132 pounds. How many grams of mannitol will this patient receive for this dose?
Correct Answer: 90 g
Rationale: Convert the patient's weight to kilograms: 132 pounds ?· 2.2 = 60 kg. Calculate the dose of mannitol: 60 kg ?? 1.5 g/kg = 90 g of mannitol.
