During descent, an airplane passenger is complaining that his “ears are plugged.” What aspect of the structure and function of the ear best accounts for the passenger’s complaint?
Question 1. A 4-year-old boy has had otitis media with effusion (OME) for several weeks and his condition has recently progressed to acute otitis media (AOM). Which of the following factors could have contributed to his AOM?
Reflux of fluid from the boy’s nose into his middle ear
A deficiency in immunoglobulin G
Accumulation of cerumen in the external acoustic meatus
Sensorineural deficits in the auditory control apparatus
Exposure to respiratory syncytial virus (RSV)
Question 2. Which of the following statements best captures the role of the adrenal cortex in maintaining homeostasis?
The adrenal cortex is responsible for the production of epinephrine and norepinephrine, which are part of the sympathetic nervous system.
The adrenal cortical hormones are primarily steroids and sex hormones.
Redundant, secondary production of adrenal cortical hormones can compensate for the loss of the adrenal glands.
Normal sexual function is dependent on adequate adrenal cortical function.
Question 3. A 29-year-old woman has been diagnosed with otosclerosis after several years of progressive hearing loss. What pathophysiologic process has characterized her diagnosis?
New, sclerotic bone has been formed around her stapes and oval window.
Her incus, malleus, and stapes have become disconnected from her normal neural pathways.
Her temporal bone is experiencing unusually rapid resorption.
Her tympanic cavity is becoming filled with bone due to inappropriate osteogenesis.
Question 4. A three-year-old girl has just been diagnosed with type 1A diabetes and her parents are currently receiving education from the diabetes education nurse at the hospital where their daughter is receiving treatment. How can the nurse best explain the etiology of their daughter’s health problem to her parents?
“The problem that underlies her diabetes is that her own body has destroyed the cells in her pancreas that produce insulin.”
“It’s not known exactly why your daughter has completely stopped making insulin, and treatment will consist of your rigidly controlling her diet.”
“This tendency to produce insufficient amounts of insulin is likely something that she inherited.”
“Environmental and lifestyle factors are known to play a part in the fact that her pancreas secretes and withholds insulin at the wrong times.”
Question 5. An endocrinologist is providing care for a 30-year-old male who has lived with the effects of increased levels of GH. Which of the following teaching points about the patient’s future health risks is most accurate?
“It’s not unusual for unusually high GH levels to cause damage to your hypothalamus.”
“GH excess inhibits your pancreas from producing enough insulin.”
“The high levels of GH that circulate in your body can result in damage to your liver.”
“When your pituitary gland is enlarged, there’s a real risk that you’ll develop some sight deficiencies.
Question 6. Following a long history of fatigue, weakness, and poor appetite, a 39-year-old male has been diagnosed with hypopituitarism. Which of the following clinical findings would most likely cause his care team to suspect that the man has an additional endocrine disorder from a different source?
The man has a low sperm count and has been unable to have children.
The man has a chronic platelet deficiency and is occasionally anemic.
The patient is 5 feet 2 inches tall and was consistently short for his age as a child.
The man displays the signs and symptoms of hypothyroidism.
Question 7. Which of the following questions is most likely to be clinically useful in the differential diagnosis of sensorineural versus conductive hearing loss?
“What medications do you currently take?”
“What effect is this hearing loss having on your quality of life?”
“Has your hearing loss developed quickly or more slowly?”
“Do you ever hear a persistent ringing in your ears?”
Question 8. As part of the diagnostic workup for a patient’s long-standing vertigo, a clinician wants to gauge the patient’s eye movements. Which of the following tests is the clinician most likely to utilize?
