A nurse is reinforcing teaching with a client who has primary open-angle glaucoma and a new prescription for timolol eye drops. Which of the following statements indicates an understanding of the teaching?
"I should take a zinc supplement while taking this medication."
"This medication will dilate my eyes."
"I should check my heart rate while taking this medication."
"This medication will darken the color of my eyes."
The Correct Answer is C
Timolol is a beta-blocker medication that is commonly prescribed for the treatment of glaucoma. It works by reducing the production of aqueous humor in the eye, thereby decreasing intraocular pressure. However, timolol can also be systemically absorbed, which may lead to cardiovascular side effects.
Checking the heart rate while taking timolol is important because beta-blockers can potentially lower heart rate and blood pressure. It is essential to monitor for any changes in heart rate or any other cardiovascular symptoms while using timolol eye drops.

Correct Answer is A
Explanation
The shoulder harnesses of the car seat should be positioned at or slightly below the level of the infant's shoulders. This helps secure the infant properly in the car seat and provides appropriate protection in the event of a crash.
Car seats for infants should not be positioned at a 90° angle. Instead, they should be installed at a reclined angle, as recommended by the car seat manufacturer. The specific recline angle can vary depending on the car seat model and the age of the child.
Additional cushions or support devices should not be placed in the car seat unless specifically recommended by the car seat manufacturer. Extra padding or cushions can interfere with the proper fit of the harness and compromise the safety of the infant.
It is not safe to have an infant's car seat in the front seat if there is an active airbag. The safest place for an infant's car seat is in the rear seat, preferably in the middle position. If the car does not have a rear seat, it is important to disable the airbag if the car seat must be placed in the front seat.
