"How did you instill the medication?"
✓
"How did you take your pulse?"

Blepharitis
Conjunctivitis
Chalazion

Floaters and flashes of light
✓
Tearing of the eye

Question 10
Which potential systemic effect should the nurse anticipate when administering a nonselective ophthalmic beta blocker?
It may reduce bronchospasm.
It may decrease peripheral edema.
It may increase heart rate.
It may mask signs of hypoglycemia.
✓
Correct Answer
It may mask signs of hypoglycemia.
Because the drug is nonselective, it can bind to and block both beta-1 and beta-2 adrenergic receptors. When it binds to beta-2 receptors, it results in a decrease in heart rate, thus masking the signs of tachycardia often seen with hypoglycemia.
