What should patients avoid when taking antihistamines, such as Benadryl (due to its effect on
CNS)? - ANS alcoholic drinks & operating heavy machinery due to drowsiness/sleepiness side
effects
concerns of prolonged use of Oxymetazoline (Afrin) - ANS rebound congestion - assess
length of tx if pt complains of this
what are important considerations for pt education when pts using MDI inhalers? - ANS pt
should hear no whistling sound when using MDI, pt holds breath for at least 10 seconds to
allow meds to deposit in lungs
why are most beta blockers contraindicated for asthma? - ANS should not be used if pt has
hx of dysrhythmia or MI
potential for causing BRONCHOSPASM
what do beta blockers do? - ANS activate beta2 receptors in bronchial smooth muscle to
cause bronchodilation during fight/flight response
if pts have severe cough & MD prescribes opiates such as Hydrocodone, what must the nurse
do? - ANS nurse must advise pt to monitor bowel movements for constipation

,what is sudafed - ANS -oral decongestant
-combination drug that can lead to tachycardia, BP, and dysrhythmias
-sympathomimetic
what types of pts should nurses be concerned about when taking sudafed? - ANS
what should pt be notified of when taking glucocorticoids? - ANS do not stop medication
abruptly, instead, taper down
what should be first priority for pt in pulmonary unit with dropping O2 sats? - ANS O2
administration
what drug class is theophyline (Theodur)? - ANS methylxanthines
what type of drug class has a very narrow range of safety (varies from
5-20 mg/dL)? - ANS methylxanthines
when should nurse question administering methylxanthines? - ANS when dosage level is
higher than 20 mg/dL
-can lead to adverse effects --> seizures
what are side effects of Theophylline? - ANS increase cardiac stimulation, tachycardia
what should pt avoid while taking Theophylline? - ANS caffeinated products
how do non-narcotics antitussives work? - ANS suppressing cough reflex in medulla

, what does nose do to air before it reaches lungs? - ANS nose warms the air
what is the first line of immunological defense? - ANS nasal mucosa
what constricts arterioles in the nose? - ANS activation of the sympathetic NS
which type of glucocorticoids produce almost no serious adverse effects? - ANS INTRANASAL
glucocorticoids
what class of drug is Fluticasone (Flonase)? - ANS -class C drug - effects on pregnancy are not
known
-pregnant pts avoid this
rapid and efficient mechanism for delivering drugs = which system? - ANS respiratory
what accounts for the instantaneous onset of action for inhaled substances? - ANS large
surface area of bronchioles & alveoli, rich blood supply to these areas
what is the best route of administration for respiratory medications? - ANS meds via inhaler
what is a good explanation for mechanism of action of bronchodilators, like Albuterol -
ANS Inhalers will widen airway due to activation of fight/flight response, or the B2
adrenergic receptors of the sympathetic NS. This activation causes smooth muscle to relax and
bronchodilation to occur.
What are some of the differences btw using inhalers that are for prevention and prophylactic
use, such as Advair, compared to inhalers that are used for the acute relief for
bronchoconstriction, such as Albuterol? - ANS
what is Guaifenesin? - ANS an expectorant - helps stimulate flow of secretion
