TOPIC 1: CONDUCTIVE HEARING LOSS
17 Questions • 9.1% of Exam • This topic covers conditions and tests related to conductive hearing loss, including causes and diagnostic
approaches.
QUESTION 1
A diagnostic test is used in a sample of 1000 patients. 500 of these patients have the disease, while
500 do not. Of those 500 patients without the disease, 30 test positive, and 470 test negative. What
is the specificity of the test?
Answer: The correct answer is 470/500.
Specificity is the proportion of patients who test negative out of the total number of patients who do not have the disease;
it is the number of true negatives overall negatives. In this example, 500/1000 patients have the disease. Of those 500
patients without the disease, 30 test positive, and 470 test negative.
QUESTION 2
Which of the following depends on the prevalence of the disease?
Answer: Positive predictive value.
Predictive values depend on the prevalence of disease in the population whereas sensitivity and specificity are intrinsic
properties of the test. Reliability refers to the consistency or stability of a measure.

QUESTION 3
If you strongly suspect that a patient is positive for a specific condition but tests negative, the
negative result may be:
Answer: False-negative test results due to a low negative predictive value.
At the individual level, your clinical suspicion is equivalent to pre-test probability and high prevalence at the population
level. Negative predictive value is inversely correlated with prevalence; therefore, your clinical suspicion translates to a
low negative predictive value, suggesting a false-negative test result.
QUESTION 4
Which of the following is an example of conductive hearing loss?
Answer: Serous OM.
QUESTION 5
A 35-year-old male uses high-potency corticosteroid cream for dermatosis, he also currently has
tinea corporis, which should the clinician advise regarding the cream.
Answer: It may exacerbate your concurrent tinea corporis.
QUESTION 6
Which of the following information about Nonpharmacologic management should be included in
parent teaching for a child with impetigo?
Answer: The goal is to debris the lesions and expose the skin surface where bacteria may be present.
QUESTION 7
Lee brings her 13-year-old son to your clinic. He has been complaining of a rash on the buttocks,
anterior thighs, and posterolateral aspects of his upper arms. He tells you it is mildly pruritic and
looks like "gooseflesh." On examination, the rash appears as small, pinpoint, follicular papules on
a mildly erythematous base. You explain to Lee that the benign condition is likely to resolve by
the time her son reaches adulthood, and it is known as:
Answer: Keratosis pilaris. The description and examination of this rash are consistent with keratosis pilaris, which most
commonly appears on the cheeks, buttocks, anterior thighs, and posterolateral aspects of the upper arms.

QUESTION 9
Your patient accidentally cut his cheek while shaving 3 days ago. Today, the region is warm,

coming from the wound. This is most likely due to:
Answer: Cellulitis.
QUESTION 10

Answer: Topical antibiotics (Do not use anesthetic drops)
QUESTION 11
Mia, a 27-year-old school teacher, has a 2-day history of severe left ear pain that began after 1
week of upper respiratory infection (URI) symptoms. On physical examination, you find that she
has acute otitis media
(AOM). She has a severe allergy to penicillin. The most appropriate antimicrobial option for this
patient is:
Answer: Azithromycin (Zithromax) (Azithromycin is not a perfect option for treating otitis media; however, it is
preferred for patients with severe penicillin allergy)
QUESTION 12
Which of the following is a differential diagnosis for conductive hearing loss?
Answer: Otitis externa.
