Anticholinergic effects:
Prior to admin:
After administration:
UR: Nursing Assessments
Baseline assessment of all systems
Focus assessment: HEENT, respiratory, med specific
Prior to admin:
Therapeutic effects: decreased symptoms
Adverse effects (see specific drugs)
After administration:
Multiple preparations/combinations; read ingredient list - multiple ingredients; reading the list; decrease likelihood to cause toxicities
Best prac: Use for shortest duration to treat symptoms; decrease likelihood toxicities/overuse to occur; discontinue if no relief
Seek medical advice if symptoms persist longer than 1 week
Cough and cold medications should not be used under 4 years of age - good education piece for parents
For topical nasal route:
UR Drugs: Education
Avoid duplicate medications, alike medications
Multiple preparations/combinations; read ingredient list - multiple ingredients; reading the list; decrease likelihood to cause toxicities
Overuse increased risks for adverse effects
Best prac: Use for shortest duration to treat symptoms; decrease likelihood toxicities/overuse to occur; discontinue if no relief
Clear nasal passages prior to administration
Clean applicator after use to maintain cleanliness
For topical nasal route:
Antitussives:
Decongestants:
Antihistamines:
Expectorants:
Agents used to treat UR
Block cough reflex
Antitussives:
Shrink mucous membranes to allow drainage; decrease production of nasal secretions
Decongestants:
Block action of histamine (H1) to decrease histamine effects
Antihistamines:
Increase productive cough to clear airways
Expectorants:
Act directly on medullary cough center to control cough spasm

AE: - Antitussives: opioid: prototypes: codeine
opioid
Nursing: - Antitussives: opioid: prototypes: codeine
Used as an oral decongestant - works as a sympathomimetic by targeting alpha-1 of SNS to cause vasoconstriction - when cause vasoconstriction in sinus and nasal passages shrink mucous membranes not allowing drainage (not as leaky) - decreases drainage and mucous production through vasoconstriction
Stimulates alpha-1 sites (sympathomimetic/vasoconstriction); Shrink mucous membrane and decrease mucous production in UR
MoA: - Oral decongestants: prototype: pseudoephedrine
Promotion of sinus drainage and decrease mucous production
Indications: - Oral decongestants: prototype: pseudoephedrine
oral; immediate and extended release available
Route: - Oral decongestants: prototype: pseudoephedrine
condition exacerbated by sympathetic activity
Contraindications: - Oral decongestants: prototype: pseudoephedrine
hypertension (BIG ONE; alpha1 receptor on blood vessels which helps vasoconstrict but if orally has systemic effects on blood vessels and vasoconstricts all over so increases BP so particularly problematic for pat with history HTN or problematic with having HTN for longer periods of time), insomnia, dizziness, anxiety
AE: - Oral decongestants: prototype: pseudoephedrine
OTC behind pharmacy counter - use to make meth; track how much buy
Nursing: - Oral decongestants: prototype: pseudoephedrine
localized anti-inflammatory action
Actions: - Topical nasal steroid decongestants: prototype: fluticasone (Flonase)
seasonal allergic rhinitis
Indications: - Topical nasal steroid decongestants: prototype: fluticasone (Flonase)
Intranasal
Route: - Topical nasal steroid decongestants: prototype: fluticasone (Flonase)
Lesion or erosion in the mucous membranes
Contraindications: - Topical nasal steroid decongestants: prototype: fluticasone (Flonase)
Local burning and irritation; dry mucous membranes; long term: break down nasal mucosa; localized effects
AE: - Topical nasal steroid decongestants: prototype: fluticasone (Flonase)
assess nasal mucosa; Takes 1 week to note change; stop if no effect after 3 weeks
Nursing: - Topical nasal steroid decongestants: prototype: fluticasone (Flonase)
H1 receptor antagonists - responsible for allergic rxn
Block histamine type 1 reactions to decrease allergic symp experiencing; antagonizing and blocking them so histamine cannot to reduce symp
Have First gen and sec gen antihistamines
H1 receptor antagonists (aka anti-histamines)
First generation: sedation and short duration
Second generation: non-drowsy and long duration
Antihistamines: H1 receptor antagonists
Diphenhydramine (Benadryl)
First generation: sedation and short duration
Intermediate level of antihistamine efficacy; high level of anticholinergic effects and sedation; occupy H1 receptor sites but also occupy muscarnic receptors part PSNS - also act anticholinergics; also passes blood brain barrier causing sedation
Many uses (other than allergies): vertigo, motion sickness, Parkinson’s disease, insomnia, urticaria, allergies, sleep aid - makes people drowsy
Crosses BBB: drowsiness
High anticholinergic effect: increased HR, urinary retention, constipation, blurred vision, dry mouth
Faster acting; shorter duration; more serious allergic rxn give this med since faster acting
Diphenhydramine (Benadryl)
Loratadine (Claritin), Fexofenadine (Allegra), Cetirizine (Zyrtec)
High antihistamine; lower anticholinergic effects and lower risk for sedation
Seasonal allergies - not in stupor because of first gen (Benadryl)
Second generation: non-drowsy and long duration
Block release of histamine from mast cells; compete for unoccupied histamine-1 receptor sites
MoA: - Antihistamine: H1 receptor antagonists: prototype: diphenhydramine (Benadryl)
allergic rhinitis (many others)
Indications: - Antihistamine: H1 receptor antagonists: prototype: diphenhydramine (Benadryl)
older adult, condition exacerbated by anticholinergic effects

The nurse is caring for a client prescribed oxymetazoline. Which assessment should the nurse perform prior to administration?
A.Lung sounds
B.Blood pressure
C.Nasal mucosa
D.Level of consciousness
Answer: C
