Question 1A 26-year-old female presents with a whitish coating on her tongue and lips. When you attempt to rub the plaque with a tongue depressor, a small amount of bleeding is noted from the oral mucosa. Her past medical history includes asthma. What diagnostic test would you perform to confirm your diagnosis?AA culture and sensitivityHint: A culture and sensitivity is used for suspected bacterial infectionsBA wet mount potassium hydroxide preparationCA gram stainHint: A gram stain is used to identify whether a bacterial pathogen is gram positive or gram negative.DA rapid strep testQuestion 1 Explanation: The history and physical are consistent with oral thrush. A wet mount potassium hydroxide preparation will reveal fungal spores and nonseptated mycelia.Question 2A 63-year-old male presents with an asymptomatic lesion in his mouth that was discovered by his dentist at a check-up. It is ill marginated with pigment ranging from medium brown to black. Parts of the lesion are raised. W hat is the next appropriate step in management?AHave the patient return in 30 days to see if the lesion resolves on its own. Hint: Given the patient's age and suspicious nature of this lesion, waiting would be ill-advised. BKOH prep of the lesionCBiopsyDCall your supervising physicianHint: This is always a good choice if you are not sure what should be done in this instance. But on the boards, there is no such luck!Question 2 Explanation: Oropharyngeal melanoma is characterized by varying pigment occurring in an irregularly shaped lesion. Although this is a rarely occur in melanoma, a biopsy should be done and any pigmented oral lesion should be excised. Areas which are raised within the lesion usually indicate sites of invasion.Question 3A 60-year-old male presents with complaints of irritation and a white plaque on his tongue. He denies pain. During physical exam you are unable to remove the white plaque from the mucosa with a tongue depressor. What is the most likely diagnosis, r epresented as follows?AGlossitisHint: Glossitis is a generalized inflammation, and loss of papillae of the tongue is caused by vitamin deficiencies, medication reactions, auto immune reactions, or psoriasisBGeographic tongueHint: Geographic tongue is an asymptomatic serpiginous area of atrophy and erythema of the anterior tongue. The condition is self-limiting.CLichen PlanusHint: Lichen planus can mimic candidiasis, squamous cell carcinoma, or hyperkeratosis, and requires a biopsy to diagnose. DOral leukoplakiaQuestion 3 Explanation: Oral leukoplakia cannot be removed from the mucosa using a tongue depressor like oral thrush can. It is considered a premalignant lesion and the chance of transformation into oral squamous cell carcinoma is 0-20%. The vast majority will not turn malignant. The condition is more common in smokers and people should be advised to stop smoking and limit alcohol consumption to reduce their risk. Management usually involves regular review of the lesion to det ect any possible malignant change early, and thereby significantly improve the prognosis, which normally is relatively poor for OSCC. Question 4A 45-year-old male presents with purulent discharge from his right ear for three weeks. He states that despite being treated by his family doctor for an ear infection one month ago, the problem continues to get worse. Upon exam, you note purulent discharge in the ear canal, an erythemic tympanic membrane, and a possible perforation. What are the pathogens most likely to culture positive?AStrep pneumoniaeHint: Strep pneumoniae is often seen in acute otitis media. BPseudomonasCE.coliHint: E.coli is a urinary tract pathogen.DCandida albicansHint: Candida albicans is a cause of vaginitisEmycoplasmaHint: mycoplasma is a respiratory pathogen.Question 4 Explanation: The clinical vignette describes a chronic otitis media.

Question 5A 38-year-old woman comes to your office with a 1-year history of episodic dizziness, ringing in both ears, a feeling of aural fullness, and hearing loss. The symptoms come on every 1 or 2 weeks and usually last for 12 hours. Nausea and vomiting are present. When asked to describe the dizziness, the patient says, â€Å"The world is spinning around me.† On physical examination, the patient has horizontal nystagmus. The slow phase of the nystagmus is to the left, and the rapid phase is to the right. Audiograms reveal bilateral sensorineural hearing loss in the low frequencies. What is the most likely diagnosis in this patient?Avestibular neuronitisBacute labyrinthitisCpositional paroxysmal vertigoDorthostatic hypotensionEMeniere diseaseQuestion 5 Explanation: This patient has Meniere disease. The classic features of Meniere disease are recurrent episodes of vertigo, fluctuating low-frequency sensorineural hearing loss, tinnitus (ringing or buzzing in the ears), and aural fullness in the affected ear. The vertigo typically lasts hours, not minutes or days. The fluctuating hearing may not be related temporally to the vertigo. For the diagnosis of Meniere disease, the characteristic pattern of vertigo lasting a matter of hours as well as sensorineural hearing loss must be present. One additional factor (aural fullness or buzzing tinnitus) should also be present.Question 6Your patient is a 64-year-old male was found to have an opacity on his lens and decreased visual acuity.

To differentiate a hordeolum from a chalazion think "H" for "HOT", tender and painful. CDacryocystitisHint: Dacryocystitis is an infection of the lacrimal sac, secondary to obstruction of the nasolacrimal duct at the junction of lacrimal sac. The term derives from the Greek dà ¡kryon (tear), cysta (sac), and -itis (inflammation). It causes pain, redness, and swelling over the inner aspect of the lower eyelid and epiphora.DForeign BodyQuestion 25 Explanation: A chalazion is an inflammatory lesion that developed when the meibomian tear gland becomes obstructed.

CSunglassesHint: Wearing sunglasses and oral analgesics help with the pain associated with corneal abrasions. DPatchingQuestion 27 Explanation: Eye patching is no longer recommended for corneal abrasions. A meta-analysis of five randomized controlled trials (RCTs) failed to reveal an increase in healing rate or improvement on a pain scale. Two subsequent RCTs (one in children, one in adults) reported similar results. In the past, patching was thought to reduce pain by reducing blinking and decreasing eyelid-induced trauma to the damaged cornea. However, the patch itself was the main cause of pain in 48 percent of patients. Children with patches had greater difficulty walking than those without patches. Furthermore, patching can result in decreased oxygen delivery, increased moisture, and a higher chance of infection. Thus, patching may actually retard the healing processQuestion 28Your patient is a 68 year-old female that presents with several months of progressively worsening central vision loss. Physical exam reveals Drusen Spots of the eye. Which of the following is the most likely diagnosis?AMacular DegenerationBOpen Angle GlaucomaHint: Open-angle glaucoma typically causes peripheral vision loss.

BDacryocystitis COrbital CellulitisHint: Orbital cellulitis is an infection that involves the fat and muscles around the eyeDHordeolumQuestion 29 Explanation: Dacryocystitis is caused by the nasolacrimal duct being blocked. The most common organism is alpha hemolytic strep, staph epidermis, and staph aureus. Empiric therapy with clindamycin and doxycycline or Bactrim is helpful. This can lead to periorbital cellulitis.Question 30Your patient is a 3 year-old male that presents with a bulging right tympanic membrane and a fever of 103.0. He has just finished a course of amoxicillin 14 days ago. Which of the following is the most appropriate treatment?AHigh-dose amoxicillin Hint: This patient is at risk for beta-lactam resistance, therefore Keflex and amoxicillin should not be used.BAugmentinCKeflexHint: This patient is at risk for beta-lactam re sistance, therefore Keflex and amoxicillin should not be used.DCiproHint: The patient is only 3, and Cipro should be avoided in this age group.Question 30 Explanation: Augmentin is the correct answer as this patient is at risk for beta-lactam resistance.Question 31Which of the following is the most appropriate management for an auricular hematoma?AObservationHint: Observation, antibiotics, and icing, together or alone are not effective.BIncision and drainageCIce for 20 minutes 4 times per day.Hint: Observation, antibiotics, and icing, together or alone are not effective.DStart cephalexinHint: Observation, antibiotics, and icing, together or alone are not effective.Question 31 Explanation: Auricular hematomas should be drained as soon as possible. Delay in treatment can lead to a cauliflower ear that is permanent deformity of the fibrocartilage of the ear that is an overgrowth.Question 32Which of the following is not an etiology of tinnitus?AASAHint: ASA, vascular problems, congenita l AV malformations, hearing loss, Eustachian tube dysfunction, and ototoxic medications are etiologies for tinnitus.BCongenital AV MalformationsHint: ASA, vascular problems, congenital AV malformations, hearing loss, Eustachian tube dysfunction, and ototoxic medications are etiologies for tinnitus.CCerumen ImpactionDVascular PathologyHint: ASA, vascular problems, congenital AV malformations, hearing loss, Eustachian tube dysfunction, and ototoxic medications are etiologies for tinnitus.Question 32 Explanation: Cerumen impaction is not an etiology of tinnitus. Question 33Your patient is an 18 year-old female that presents with right side purulent otorrhea.    Visualized tympanic membrane on the right side reveals a small perforation.    Which of the following is the most appropriate treatment regimen?AFloxin Otic DropsBAmoxicillin and Floxin Otic DropsCZithromaxDAmoxicillinQuestion 33 Explanation: A perforated tympanic membrane caused by infection needs to be treated with oral an tibiotics as well as topical antibiotic ear drops.    When there is a perforation the ear canal is contaminated with the purulent drainageQuestion 34Which of the following bacteria is not a possible cause of bacterial tonsillitis?AGroup A Streptococcus Hint: See answer for explanationBNeisseria Gonorrhea Hint: See answer for explanationCMycoplasmaHint: See answer for explanationDProteusQuestion 34 Explanation: All of the following are possible causes of bacterial tonsillitis: Group A Streptococcus, Neisseria Gonorrhea, Mycoplasma, Chlamydia, Tularemia, and Group C and Group G Strep.

Airway protection is the mainstay of treatment. The patient usually needs to be intubated for 2-3 days prior to weaning attempts. The role of steroids is controversial. Vancomycin hel ps with anti-staph coverage and Ceftriaxone covers the most common organism haemophilus influenza type B. Anesthesia and/ or ENT should be consulted for airway management.Question 37Which of the following is not true about peritonsillar abscess?AGroup A Streptococcus is the most common organism BMRI of the soft tissue neck is the imaging study of choice for confirmation CAppropriate empiric antibiotic therapy includes clindamycin or Unasyn DVancomycin is an appropriate add-on antibiotic if there are airway issuesQuestion 37 Explanation: CT scan of soft tissue of the neck with IV contrast is the imaging study of choice.Group A Streptococcus is the most common organism.    There are also so cases of staph.    Appropriate empiric antibiotic therapy includes Clindamycin and Unasyn.

Question 43Your patient is a 46 year-old male that presents with a piece of metal on cornea with a rust ring that is approximately twelve hours old.  Which of the following is not an acceptable method to attempt removal?A25 gauge needle Hint: A 25 gauge needle is an acceptable method for removal.BCotton Swab Hint: A cotton swab is an acceptable methods for removal.CMagnetDOphthoburrHint: An ophthoburr is an acceptable method for removal.Question 43 Explanation: Magnets are not safe for removal metal foreign bodies from the eye.Question 44Your patient is 64 year old female that presents with sudden onset of right eye pain, redness, and photophobia with tearing.    Slit lamp exam reveals some conjunctival erythema and a shallow anteri or chamber.    There is no ciliary flair.    The intraocular pressure is 44 in the right eye.    All of the following are acceptable management options except?AReferral to Ophthalmology Hint: This patient should be referred to ophthalmology.BBegin Xaltan Drops Hint: Xalatan drops help lower the pressureCInstill Cycloplegic Drops DStart Norco as needed Hint: Analgesics PRN are appropriateQuestion 44 Explanation: This patient has acute closure glaucoma. Installation of a cycloplegic can increase the pressure and make the patient worse. A cycloplegic drop causes paralysis of the ciliary muscle of the eye, resulting in a loss of accommodation and flexibility. Question 45Your patient is a 45 year old female that presents with a sudden onset of visual loss in the left eye.    Funduscopic exam reveals hyperemia and swelling and blurring of the optic disc.    There is no history of headache.    The patient's other eye is normal.    The patient describes a scotoma in the centra l vision of his affected eye.    Based upon this data, which of the following is the most likely diagnosis?APseudotumor cerebriHint: Pseudotumor cerebri usually affects both eyes and is accompanied with a headacheBOphthalmic migraine Hint: Ophthalmic migraine usually has headaches with it and will not have any optic disc changes on exam. CRetinal detachment Hint: Retinal detachment does not have these visual field changes and will not have these optic disc changes on physical exam.DOptic NeuritisQuestion 45 Explanation: Pseudotumor cerebri usually affects both eyes and is accompanied with a headache. Ophthalmic migraine usually has headaches with it and will not have any optic disc changes on exam. Retinal detachment does not have these visual field changes and will not have these optic disc changes on physical exam.Question 46Your patient is a 69 year old female that presents with a sudden onset of floaters in the right eye, flashes of light, and floaters resemble a cobweb.    There is no pain.    Which of the following is the most likely diagnosis?AOptic Neuritis Hint: Optic neuritis does not have this presentationBRetinal Detachment CPseudotumor cerebri Hint: Pseudotumor cerebri typically affects both eyes and will have a headache.DMacular Degeneration Hint: Macular degeneration is more of a slower onset and does not have these visual field changes typically.Question 46 Explanation: This is a common presentation of retinal detachment. Question 47A 23-year-old woman comes to your office with a 6-month history of dizziness. She â€Å"feels dizzy† when she stands up (as if she is going to faint). The sensation disappears within a minute. She has a history of major depression. She started taking doxepin 6 months ago, and her depression has improved much since that time. The patient’s blood pressure is 140/ 90 mm Hg sitting and decreases to 90/ 70 mm Hg when she stands. There is no ataxia, nystagmus, or other symptoms.   What is the most li kely diagnosis in this patient?Avestibular neuronitisBacute labyrinthitisCbenign positional paroxysmal vertigoDorthostatic hypotensionQuestion 47 Explanation: d.This patient has orthostatic hypotension. This case illustrates the importance of obtaining an accurate history in the patient who complains of â€Å"feeling dizzy.† In any patient who has this complaint, it is important to ask four specific questions: (1) Can you describe your dizziness? (2) How much of the dizziness is a sensation of the â€Å"world spinning around you,† and how much would be a sensation of â€Å"things going black in front of you and a feeling that you’re about to pass out†? (3) How long does the feeling of dizziness last— seconds, minutes, or hours? and (4) Are there any other symptoms present when you feel dizzy, such as deafness, ear fullness, or ringing in the ears? The answers to these questions are the most important clues to leading you toward a diagnosis. This pa tient does not have clear symptoms of vertigo, and one should focus on non– vertigo-related dizziness. Orthostatic hypotension is typically initiated after standing up suddenly. There is a transient lack of cerebral blood flow. The feeling described is that of a subjective dizziness, and the patient feels as if he or she might faint. It is not associated with any other neurologic sensations or ear symptoms. It is also characterized by a lack of symptoms when sitting or lying. Medications are the most likely culprits in this scenario, but occasionally there is no clear etiology for the autonomic disturbance. In this clinical case problem, the orthostatic hypotension is almost certainly associated with the beginning of the tricyclic antidepressant therapy 6 months ago.Question 48A 30-year-old man comes to your office for assessment of dizziness. The dizziness occurs when he rolls over from the lying position to either the left side or the right side. It also occurs when he is l ooking up. He describes a sensation of â€Å"the world spinning around† him. The episodes usually last 10 to 15 seconds. They have been occurring for the past 6 months and occur on average one or two times per day.Avestibular neuronitisBacute labyrinthitisCpositional paroxysmal vertigoDMeniere diseaseQuestion 48 Explanation: This patient has positional paroxysmal vertigo (PPV), a disorder that consists of brief episodes (lasting 2 to 10 seconds) usually caused by turning the head. PPV is caused by the formation of crystalline debris in the semicircular canals that leads to labyrinthine irritation, causing vertigo and nystagmus.Question 49A 39-year-old woman comes to your office with a 2-day history of â€Å"unrelenting dizziness.† The room feels like it is spinning, and there is associated nausea and vomiting. There has been no hearing loss, tinnitus, or sensation of aural fullness. The patient has just recovered from an upper respiratory tract infection. The patient i s afebrile. On examination, nystagmus is present. The slow phase of the nystagmus is toward the left, and the rapid phase of the nystagmus is toward the right. There is a significant ataxia present.Avestibular neuronitisBacute labyrinthitisHint: The features of acute labyrinthitis are similar to those of vestibular neuronitis, except it includes significant sensorineural hearing loss.Cpositional vertigoDorthostatic hypotensionQuestion 49 Explanation: This patient has a left vestibular neuronitis. The etiology of this disorder is commonly associated with a viral infection (such as adenovirus) that follows a respiratory tract infection and involves some portion of the vestibular system but with total sparing of the cochlear area. It most commonly affects young or middle-aged adults. The disorder consists of severe vertigo with associated ataxia and nausea and vomiting. There is no hearing loss, aural pain, or other symptoms, which is helpful in distinguishing it from other causes of v ertigo. Recovery usually takes 1 or 2 weeks. The treatment of choice for a patient with vestibular neuronitis is rest, reassurance, and antiemetics.Question 50A 37-year-old woman comes to your office for assessment of hearing loss. She has had problems intermittently for the past 12 months. On examination, the Weber tuning fork test lateralizes to the right ear, and the Rinne tuning fork test is negative in the right ear (bone conduction is greater than air conduction [BC AC]). This suggests which of the following? Aa right-sided conductive hearing lossBa left-sided conductive hearing lossCa right-sided sensorineural hearing lossDa left-sided sensorineural hearing lossQuestion 50 Explanation: The characterization of hearing loss can be localized by a combination of the Weber test and the Rinne test. In the Weber test, placement of a 512-Hz tuning fork on the skull in the midline or on the teeth stimulates both cochleae simultaneously. If the patient has a conductive hearing loss in one ear, the sound will be perceived loudest in the affected ear (i.e., it will lateralize). When a unilateral sensorineural hearing loss is present, the tone is heard in the unaffected ear. The Rinne test compares air conduction with bone conduction. Normally, AC is greater than BC. Sound stimulation by air in front of the pinna is normally perceived twice as long as sound placed on the mastoid process (AC > BC). With conductive hearing loss, the duration of AC is less than BC (i.e., negative Rinne test result). In the presence of sensorineural hearing loss, the durations of both AC and BC are reduced; however, the 2: 1 ratio remains the same (i.e., a positive Rinne test result). Facts for this question: (1) Bone conduction is greater than air conduction. This indicates that this is a conductive hearing loss. (2) In conductive hearing loss, the Weber test lateralizes to the affected ear, and because the Weber test lateralized to the right ear in this patient, she has a unilateral right-sided conductive hearing loss.
