A nurse working in an urgent care clinic is collecting data from a client who takes montelukast.
Which of the following is an expected therapeutic effect of this medication?

Choice A rationale:

The first dose of the varicella vaccine is usually given when the child is between 12 to 15 months old, not after 3 years.

Choice B rationale:

Aspirin should not be given to children due to the risk of Reye’s syndrome. This syndrome is a rare but serious condition that causes swelling in the liver and brain.

Choice C rationale:

The varicella vaccine should be avoided in children who have leukemia or any other condition that weakens the immune system.

Choice D rationale:

The varicella vaccine is not contraindicated for children who are allergic to eggs. It’s some other vaccines like influenza that have this restriction.

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.
