Q

Assessments for patient taking beta agonists.

A

allergies to fluorocarbon
taking of caffeine (chocolate, tea, coffee, candy, sodas).
use of OTC medications containing caffeine (appetite suppressants, pain relievers).
educational level and readiness to learn.

2
Q

why is the intake of caffeine important to determine in patient taking beta agonists such as albuterol?

A

because of its sympathomimetic effects and possible potentiation of adverse effects such as tachycardia, hypertension, vascular headache and tremors.

bronchospasms
4
Q

Assessments for patients taking xanthine derivatives (eg. theophylline)

A

GI reflux- assess for bowel and preexisting disease such as gastroesophageal reglux, ulcers.
results of renal and liver function test
urinary patterns (due to transient urinary frequency)
dietary questions about low-carbohydrate, high-protein, and charcoal-broiled meat.
OTC medications and caffeine containing foods.

27
Q

a patient who is taking a xanthine derivative asks the nurse about drinking coffee with the medication. what would be the nurse’s best answer?

A

coffee, tea, chocolate, cocoa and cola beverages contain xanthine.
Consumption of these beverages increase or exacerbates the CNS which may have a severe impact and could be life threatening.
The caffeine containing products should be avoided while on xanthine.

28
Q

A

They are used for prophylaxis in asthmatic attacks when taken on a long-term basis.
There are not used to treat acute attacks.
For best effect, patient should take the medication regularly, as ordered even if the symptoms improve and patient is feeling better.
