Rationales
1. The NP recognizes common symptoms for allergic rhinitis include:
A. Bloody nasal discharge
B. Purulent nasal discharge
C. Cough and fever
D. Runny nose and itchy eyes
Correct Answer: D. Runny nose and itchy eyes
Rationale:
1. Allergic rhinitis is triggered by allergens such as pollen, dust, or pet dander.
2. Common symptoms include rhinorrhea (runny nose), sneezing, nasal
congestion, and pruritus (itchy eyes/nose).
3. Bloody discharge suggests trauma or dryness, not allergy.
4. Purulent discharge indicates infection (sinusitis or bacterial rhinosinusitis).
5. Cough and fever are more typical of infectious or viral processes.
2. Nasal mucosa is typically _____ in allergic rhinitis and _____ in
idiopathic rhinitis.
A. erythematous; pale
B. pale; erythematous
, 2|Page
C. blue; erythematous
D. red; erythematous
Correct Answer: B. pale; erythematous
Rationale:
1. In allergic rhinitis, nasal mucosa appears pale, bluish, or boggy due to
edema and vasoconstriction from histamine release.
2. In idiopathic (non-allergic) rhinitis, mucosa is typically erythematous
(red) due to vasodilation.
3. This distinction helps differentiate allergic from non-allergic causes.
4. Erythematous mucosa is also seen in infectious rhinitis.
3. The NP recognizes common causes of tympanic membrane
perforation include:
A. Pressure and inflammation of AOM, tugging on the ear, physical trauma
B. Sinus inflammation, external ear canal irritation, barotrauma
C. Barotrauma, physical trauma, blast injury, pressure and inflammation of
AOM
D. Sinus infection, pharyngitis, and barotrauma
Correct Answer: C. Barotrauma, physical trauma, blast injury,
pressure and inflammation of AOM
Rationale:
1. Acute otitis media (AOM) causes pressure buildup that can rupture the
tympanic membrane.
2. Physical trauma (e.g., Q-tip use, foreign objects) directly perforates the
TM.
3. Barotrauma from rapid pressure changes (air travel, diving) can cause
perforation.
4. Blast injury from explosions creates pressure waves that rupture the TM.
5. Tugging on the ear does not typically cause TM perforation; it is a sign of
otalgia in children.
4. Why has there been a dramatic decline in epiglottitis in children?
A. Due to vaccination for influenza virus
B. Due to vaccination for Hemophilus organisms
C. Due to decreased virulence of the strep bacteria
D. Due to decreased incidence of chickenpox
Correct Answer: B. Due to vaccination for Hemophilus organisms
