A clinic nurse is giving instructions to a mother on the proper technique of applying ophthalmic ointment to her preschool-age child who has conjunctivitis. Which of the following should the nurse include in the instructions?
“Warm the ointment by placing the tube in glass of hot tap water”
"Discard the first bead of ointment before each application."
"Instruct your child to squeeze his eyes shut following application."
"Cleanse the eye with a wet cotton ball in a direction towards the inner canthus before applying the ointment."
The Correct Answer is B
the first bead of ointment may be contaminated with bacteria from the tip of the tube or the surrounding skin. Discarding this initial bead ensures that the subsequent application is sterile and reduces the risk of introducing infection into the eye.
A. Warming the ointment by placing the tube in hot tap water alters the consistency of the ointment and can potentially cause burns to the child's delicate eye tissue.
C. Instructing the child to squeeze his eyes shut following application is not necessary. The eyes should be closed gently
D. Cleansing the eye should be done from the inner corner moving outward
