A nurse is reinforcing teaching with the family of a client who has a new prescription for donepezil.
Which of the following therapeutic effects should the nurse inform the family to expect?

Choice A rationale:

Donepezil does not decrease urinary output. It works by increasing the amount of a certain naturally occurring substance in the brain.

Choice B rationale:

Donepezil does not improve pulmonary function. Its primary function is to improve mental function.

Choice C rationale:

Donepezil improves cognitive function. It can improve thinking ability and slow the loss of these abilities in people who have Alzheimer’s disease.

Choice D rationale:

Donepezil does not decrease the incidence of seizures. In fact, patients should inform their healthcare provider if they have a history of seizures before starting donepezil.

Choice A rationale:

While a tuberculin syringe can be used for insulin administration, it’s not necessary when mixing NPH and regular insulin. Insulin syringes are typically used for this purpose.

Choice B rationale:

Injecting air into each vial before withdrawing insulin helps equalize pressure and makes it easier to draw up the insulin. This should be done before withdrawing any insulin.

Choice C rationale:

Withdrawing NPH insulin first contradicts the standard practice of drawing up insulins. The usual recommendation is to draw up short-acting (regular) insulin before intermediate-acting (NPH) insulin.

Choice D rationale:

Shaking the regular insulin vial is unnecessary and could potentially create bubbles, making it harder to draw up the correct dose of insulin.
