Which of the following is the most common presenting symptom of acute otitis media?
Tinnitus
Ear pain (otalgia)
Nasal congestion
Vertigo
Acute otitis media typically presents with ear pain due to inflammation of the middle ear. Other symptoms like tinnitus or vertigo are less common in uncomplicated cases.
The cochlea is found in which part of the ear?
External ear
Middle ear
Inner ear
Eustachian tube
The cochlea is a spiral structure located in the inner ear that converts sound vibrations into nerve impulses. The middle and external ear serve other functions such as sound conduction and protection.
What is the primary function of the nasal turbinates?
Support the nasal septum
Humidify and warm inhaled air
Drain sinus secretions
Detect odors
Nasal turbinates increase mucosal surface area to humidify, warm, and filter inhaled air. They are not directly involved in odor detection or structural support of the septum.
Palatine tonsils are located between which two structures in the oropharynx?
Tongue base and soft palate
Pharyngeal and lingual tonsils
Uvula and epiglottis
Palatoglossal and palatopharyngeal arches
The palatine tonsils reside in the tonsillar fossa between the palatoglossal and palatopharyngeal arches. Other listed landmarks do not define the tonsillar bed.
A normal Rinne test result is indicated by which finding?
No sound heard by either conduction
Equal air and bone conduction
Bone conduction greater than air conduction
Air conduction greater than bone conduction
A positive Rinne test (normal) is when air conduction exceeds bone conduction. If bone conduction is greater, this suggests conductive hearing loss.
In the Weber test, sound lateralizes to the affected ear in which type of hearing loss?
Sensorineural hearing loss
Normal hearing
Mixed hearing loss
Conductive hearing loss
In conductive hearing loss, bone-conducted sound is perceived as louder in the affected ear on Weber testing. In sensorineural loss it lateralizes to the good ear.
Anterior epistaxis most commonly arises from which vascular plexus?
Woodruff's plexus
Posterior ethmoidal artery
Sphenopalatine artery
Kiesselbach's plexus
Kiesselbach's plexus on the anteroinferior nasal septum is the most common source of anterior nosebleeds. Posterior sources are less frequent.
Which is the most common bacterial pathogen in acute bacterial sinusitis?
Streptococcus pneumoniae
Moraxella catarrhalis
Haemophilus influenzae
Staphylococcus aureus
Streptococcus pneumoniae is the most frequently isolated organism in acute bacterial sinusitis. H. influenzae and M. catarrhalis are also common but secondary.
Vestibular neuritis typically presents with which clinical feature?
Intermittent vertigo preceded by aura
Progressive hearing loss and tinnitus
Acute severe vertigo without hearing loss
Facial weakness with vertigo
Vestibular neuritis causes sudden, severe vertigo without auditory symptoms. Hearing involvement suggests labyrinthitis rather than isolated vestibular neuritis.
What is the most common etiology of acute laryngitis?
Viral infection
Mechanical trauma
Gastroesophageal reflux
Bacterial infection
Acute laryngitis is most often caused by viral upper respiratory infections. Bacterial causes and reflux are less frequent acute triggers.
On pure-tone audiometry, sensorineural hearing loss is characterized by which pattern?
Air and bone conduction thresholds both depressed with no gap
Bone conduction better than air conduction
Air conduction depressed with gap above bone
Normal thresholds at all frequencies
Sensorineural loss shows parallel, depressed air and bone conduction thresholds with no air-bone gap. Conductive loss would show a gap.
Nasal polyps in an adult patient are most strongly associated with which condition?
Aspirin-exacerbated respiratory disease
Acute bacterial sinusitis
Acute viral rhinitis
Deviated nasal septum
Aspirin-exacerbated respiratory disease (SAM triad) commonly features asthma, aspirin sensitivity, and nasal polyps. Acute infections are less likely to produce polyps.
What is the imaging modality of choice for initial evaluation of a thyroid nodule?
MRI of the neck
Radioactive iodine scan
Ultrasound of the neck
Contrast-enhanced CT scan
Neck ultrasound is the first-line imaging to characterize thyroid nodules and guide fine-needle aspiration decisions. CT and MRI are reserved for complex cases.
How does otitis media with effusion (OME) differ from acute otitis media (AOM)?
Always associated with systemic illness
Absence of acute symptoms like pain or fever
Rapid onset with drainage from the ear
Presence of severe ear pain and erythema
OME involves fluid accumulation without acute inflammatory signs such as pain or fever. AOM presents with acute pain, fever, and erythematous tympanic membrane.
What is the first-line pharmacologic treatment for moderate-to-severe allergic rhinitis?
Oral antihistamines
Oral decongestants
Intranasal corticosteroids
Leukotriene receptor antagonists
Intranasal corticosteroids are most effective for moderate-to-severe allergic rhinitis by reducing mucosal inflammation. Antihistamines and decongestants are less potent.
Which tympanometry finding is characteristic of middle ear effusion?
Type As (shallow compliance)
Type A (normal)
Type Ad (hypercompliant)
Type B (flat tracing)
A Type B tympanogram shows a flat compliance curve, indicating fluid in the middle ear. Type As and Ad indicate stiff or hypermobile systems, respectively.
A cholesteatoma most commonly presents with which clinical feature?
Severe ear pain and high fever
Painless, foul-smelling otorrhea and conductive hearing loss
Rapid onset sensorineural hearing loss
Intermittent vertigo with tinnitus
Cholesteatomas often cause chronic, foul-smelling discharge and a conductive hearing loss due to keratin debris eroding ossicles. Pain and fever are uncommon.
Why are parotid gland tumors often associated with facial nerve involvement?
The facial nerve traverses the parotid gland
Close proximity to the phrenic nerve
Encapsulation by the sternocleidomastoid muscle
Rich lymphatic drainage around the gland
The facial nerve runs through the substance of the parotid gland, dividing it into superficial and deep lobes. Tumors can impinge on or invade the nerve.
Which laryngoscopic finding raises concern for laryngeal carcinoma?
Bilateral false cord movement
Diffuse epiglottic edema
Unilateral vocal cord paralysis
Laryngeal web formation
Unilateral vocal cord paralysis can signal infiltration of the recurrent laryngeal nerve by malignancy. Other findings are less specific for carcinoma.
Which feature differentiates Ménière's disease from acute labyrinthitis?
Sudden sensorineural hearing loss only
Continuous vertigo without auditory symptoms
Facial numbness accompanying vertigo
Episodic vertigo with fluctuating hearing loss and tinnitus
Ménière's disease is characterized by episodic vertigo coupled with fluctuating hearing loss and tinnitus. Labyrinthitis presents with continuous vertigo and auditory involvement.
