Q1.
A patient presents with a painful, erythematous ear canal and purulent otorrhea. The
tympanic membrane is intact. Which finding most strongly supports a diagnosis of
malignant otitis externa rather than simple otitis externa?
A. Presence of granulation tissue in the ear B. Severe pain on manipulation of the pinna
canal
C. Hearing loss out of proportion to the D. History of recent swimming
findings
Correct: A - Presence of granulation tissue in the ear canal
Rationale:Malignant (necrotizing) otitis externa is an invasive infection, typically in
immunocompromised patients, that extends beyond the ear canal. Granulation tissue in the
ear canal is a classic sign of invasive disease, whereas simple otitis externa is limited to the
canal and does not produce granulation tissue. Pain on manipulation is characteristic of both,
hearing loss is common in both, and swimming is a risk factor for simple otitis externa.
Why the other answers are wrong:
B. Severe pain on manipulation is a hallmark of simple otitis externa, not specific to malignant.
C. Hearing loss can occur in both due to canal edema and debris.
D. Swimming is a risk factor for simple otitis externa, not malignant.

Q2.
Which of the following best explains the mechanism by which prolonged use of intranasal
decongestants leads to rebound congestion?
A. Downregulation of alpha-adrenergic B. Upregulation of beta-adrenergic receptors
receptors in nasal mucosa in nasal mucosa
C. Increased histamine release from mast D. Desensitization of cholinergic receptors in
cells nasal glands
Correct: A - Downregulation of alpha-adrenergic receptors in nasal mucosa
Rationale:Prolonged use of topical alpha-adrenergic agonists (e.g., oxymetazoline) causes
receptor downregulation, leading to tolerance and rebound vasodilation when the drug is
withdrawn. This is the primary mechanism of rhinitis medicamentosa. Beta-receptor
upregulation is not relevant; histamine release is not directly caused by decongestants;
cholinergic desensitization is not involved.

, Section A - HEAD AND NECK Anatomy AND Physiology
Why the other answers are wrong:
B. Beta-receptor upregulation is not a mechanism of decongestant tolerance.
C. Histamine release is not the direct mechanism; it's a secondary inflammatory response.
D. Cholinergic receptors are not the target of decongestants.
Reference: Lehne, R. A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 64.
Q3.
A patient reports sudden, painless, unilateral vision loss described as a 'curtain' coming
down. Which finding on fundoscopic examination is most consistent with the diagnosis?
A. Retinal detachment with a gray, elevated B. Retinal hemorrhage with cotton-wool
retina spots
C. Optic disc swelling with blurred margins D. Macular edema with hard exudates
Correct: A - Retinal detachment with a gray, elevated retina
Rationale:Painless, sudden vision loss with a curtain-like shadow is classic for retinal
detachment. Fundoscopy reveals a gray, elevated retina with possible tears. Retinal
hemorrhage with cotton-wool spots suggests hypertensive retinopathy or vascular occlusion;
optic disc swelling suggests papilledema; macular edema with exudates suggests diabetic
retinopathy.
Why the other answers are wrong:
B. These findings are typical of retinal vascular disease, not detachment.
C. Optic disc swelling is seen in papilledema or optic neuritis.
D. Macular edema with exudates is characteristic of diabetic retinopathy.

14.
Q4.
Which of the following is the most appropriate next step in managing a patient with acute
bacterial rhinosinusitis who has not improved after 7 days of amoxicillin-clavulanate?
A. Switch to a respiratory fluoroquinolone B. Add an intranasal corticosteroid and
such as levofloxacin continue the current antibiotic
C. Obtain a sinus CT to confirm the D. Refer for endoscopic sinus surgery
diagnosis before changing therapy
Correct: A - Switch to a respiratory fluoroquinolone such as levofloxacin
Rationale:According to IDSA guidelines, if a patient fails to improve after 7 days of first-line
antibiotic therapy, a change to a respiratory fluoroquinolone (e.g., levofloxacin) or a
higher-dose amoxicillin-clavulanate is recommended. CT is not needed for uncomplicated
cases; adding intranasal steroids is adjunctive, not a replacement; surgery is reserved for
complications or chronic disease.
