Chapter 31: Nasal Congestion and Cough Flashcards
Common Cold
viral infection of the respiratory tract
Incubation time is about 5
days, they will manifest as a cold. Person contagious best after the 3rd day. It can last 7 days on average.
Hand hygiene is the most indicated
Prescription antitussive agents (Dextromethorphan)
prototype, its ingredient is in most OTC drugs
Prescription antitussive agents (Benzonatate)
Acts by anesthetizing stretch
receptors in the respiratory passages, thereby decreasing coughing
Prescription antitussive agents (codeine / hydrocodone)
opioid narcotics, have antitussive effects in relatively small doses by centrally acting
Prescription antitussive agents (adverse reactions)
codeine is converted to morphine, and the potential for respiratory depression and death may occur
Caution in administering in pt with head injuries and increased
intracranial pressure, acute abdominal disorders, seizure disorders
Prescription antitussive agents (pt teaching)
Alcohol Increases central nervous system depression
St. John’s wort, tryptophan, monoamine oxidase inhibitors,
and serotonin reuptake inhibitors increase the risk of serotonin syndrome
Nasal Decongestants
Pseudoephedrine - prototype, produces vasoconstriction, and shrinks nasal mucosa membranes, resulting in decreased nasal congestion
Nasal Decongestants (med interactions that increase effect)
Cocaine, digoxin, general anesthetics, monoamine oxidase (MAO) inhibitors, other
adrenergic drugs
Nasal Decongestants (non-med interactions)
Caffeine and the herb coleus can enhance the adverse effects of pseudoephedrine
Tannin-containing herbs such as
green or black tea or witch hazel may decrease the absorption and effectiveness of the drug
Nasal Decongestant (pt teaching)
Meds relieve symptoms, but do not cure condition
Consuming adequate fluids,
humidification of the environment, and throat lozenges can relieve mouth dryness
and cough
Blow the nose gently before instilling nasal solutions or
sprays
Dextromethorphan (use)
relieve dry, nonproductive cough
Dextromethorphan (dosing / overdosing)
Dosing: liquid and lozenges, max daily dose of 120mg / day
Overdosing: can produce hallucinations, and disassociation
Dextromethorphan (assessment)
Assess frequency and productivity of cough, lung sounds, amount and type of sputum reduced
Dextromethorphan (pt teaching)
increased intake can lead
to increased central nervous system impairment.
Take cough syrups undiluted
avoid eating and drinking for approximately 30 minutes
Guaifenesin (uses)
Used with productive coughs, guaifenesin loosens mucus from the respiratory tract
Mucinex is prototype
