What is the INR range for most
2-3
What is the acceptable range for INR for those with mechanical heart valve
2.5-3.5
What does high INR mean
What is low INR mean
INR measures how long it takes for your body to clot
High INR:
Prolonged bleeding risk
Frequent nose bleeds
Bloody/ tarry stools
Hematuria
Petechiae
Excessive bruising
Low:
Can reduce the anticoagulant effect of warfarin if you eat lots of food with vitamin K (green leafy, broccoli)
Which antibiotic med has an increase risk in Achilles tendon rupture
Fluoroquinolones (levofloxacin)
What does high sensitivity mean
It can correctly identify an individual who has the disease.
What does it mean to have high specificity
High specificity is the ability of a test to correctly identify an individual who does not have the disease.
What is positive predictive value
Positive predictive value is the probability that subjects with a positive screening test truly have the disease
What is negative predictive value
Negative predictive value is the probability that subjects who have a negative screening test truly do not have the disease.
Labyryntitis presents like
rapid onset of severe vertigo with nausea, vomiting, and gait instability.
BPPV presents like
recurrent episodes of vertigo provoked by certain head movements.
Ménière’s disease present as
Ménière’s disease experience vertigo as a rotatory spinning or rocking with nausea and vomiting, hearing loss, and tinnitus.
A patient presents with reduced hearing, tinnitus, and fullness in the affected ear. The patient reports frequent spontaneous episodes of vertigo, each lasting at least 30 to 45 minutes. Audiometry confirms sensorineural hearing loss in the affected ear. Which of the following is the first-line treatment for this diagnosis based on the clinical findings?
A.Vestibular rehabilitation therapy
B.Lifestyle modification including salt restriction
C.Pharmacotherapy with diuretics
D.Glucocorticoid therapy for symptom management
Answer: B. Lifestyle modification including salt restriction
This patient is presenting with findings supporting the clinical diagnosis of Ménière’s disease. Patients experience progressive hearing loss with vestibular symptoms, including spontaneous episodes of vertigo that last 20 minutes to 12 hours and occur two or more times, and fluctuating aural symptoms (reduced hearing, tinnitus, or fullness). Audiometry confirms sensorineural hearing loss. Initial therapy includes lifestyle modifications such as salt restriction and limiting of caffeine and alcohol consumption. Vestibular rehabilitation and pharmacotherapy may be considered with patients with persistent disequilibrium and refractory symptoms.
What is the first-line treatment for allergic rhinitis?
A.Saline nasal spray
B.Oral antihistamine
C.Topical nasal decongestant spray
D.Topical nasal steroid spray
Answer: D. Topical nasal steroid spray
The first-line treatment for allergic rhinitis is a topical nasal steroid spray, which is used once or twice per day. Allergic rhinitis can be seasonal (e.g., due to ragweed, mold, or pollens), or it can be due to an indoor allergen, such as dust mites. If it is severe or accompanied by asthma, referral to an allergist for allergy testing is helpful. Topical nasal decongestant spray (e.g., Afrin) is for short-term use only because it can result in a rebound effect with worsening of symptoms (rhinitis medicamentosa).
A patient presents with a severe sore throat, fever, and a “hot potato,” or muffled, voice. The patient is drooling due to difficulty opening the mouth. Unilateral swelling and a bulging red mass are noted on physical examination. These findings are suggestive of which diagnosis?
A.Epiglottis
B.Acute pharyngitis
C.Infectious mononucleosis
D.Peritonsillar abscess
Answer: D. Peritonsillar abscess
These findings are suggestive of a peritonsillar abscess, a collection of pus between the palatine tonsil and the pharyngeal muscles. Common symptoms include a severe sore throat; a fever; a “hot potato,” or muffled, voice; drooling; and trismus. Physical assessment reveals an enlarged tonsil with deviation of the uvula. Epiglottis also presents with fever and drooling; however, airway stridor and respiratory distress are more common, along with “sniffing” posture. Acute pharyngitis causes nonspecific symptoms such as a sore throat and cervical lymphadenopathy. Infectious mononucleosis presents with fever, pharyngitis, adenopathy, fatigue, and atypical lymphocytosis.
A patient presents with conductive hearing loss secondary to otitis media. What findings are expected with the Rinne and Weber tests?
A.Weber lateralizes to good ear
B.Bone conduction > air conduction
C.No lateralization noted on the Weber test
D.Air conduction > bone conduction
Answer: B. Bone conduction > air conduction
An abnormal Rinne test (bone conduction > air conduction) is seen in patients with conductive hearing loss. The Weber test suggests sensorineural hearing loss if the sound lateralizes to the good side; conductive hearing loss is suggested if the sound lateralizes to the bad side.
