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?
Question options:
Exposure to respiratory syncytial virus (RSV)
Sensorineural deficits in the auditory control apparatus
Accumulation of cerumen in the external acoustic meatus
A deficiency in immunoglobulin G
Reflux of fluid from the boy's nose into his middle ear
Answer- Reflux of fluid from the boy's nose into his middle ear
,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?
Air must be able to flow between the middle ear and the nasopharynx in
order to accommodate pressure changes.
The tympanic membrane is selectively permeable in order to
accommodate pressure changes and this capacity is often impaired
during upper respiratory infections.
The Eustachian tubes must remain patent to equalize pressure between
the middle ear and inner ear.
The inner ear adjusts its volume in response to atmospheric pressure,
increasing during low pressure and decreasing in high pressure.
Answer- Air must be able to flow between the middle ear and the
nasopharynx in order to accommodate pressure changes.
Following the identification of low levels of T3 and T4 coupled with the
presence of a goiter, a 28-year-old female has been diagnosed with
Hashimoto thyroiditis. In light of this diagnosis, which of the following
assessment results would constitute an unexpected finding?
Increased white cell count and audible crackles on chest auscultation
,Coarse, dry skin and hair with decreased sweat production
Recent weight gains despite a loss of appetite and chronic fatigue
The presence of myxedema in the woman's face and extremities
Answer- Increased white cell count and audible crackles on chest
auscultation
A patient with a new diagnosis of an endocrine disorder is unclear about
how the body can control the levels of different hormones over time.
Which of the following statements most accurately underlies the
dominant regulation process of hormone levels in the body?
The pituitary gland is genetically programmed to stimulate and inhibit
hormone production and/or release based on needs at different points in
the life cycle.
The hypothalamus ensures that hormone levels correspond accurately to
the diurnal cycle.
With input from various sensors, hormone production and release are
adjusted based on existing hormone levels.
, A positive feedback cycle ensures that stable levels of hormones exist in
the body over time.
Answer- With input from various sensors, hormone production and
release are adjusted based on existing hormone levels.
A care aide at a long-term care facility has informed a resident's nurse
practitioner that the 80-year-old woman's eyes appear to be inflamed and
her eyelids are caked with sticky secretions. The woman subsequently
has been diagnosed with posterior blepharitis. Which of the following
treatments is the nurse practitioner likely to initiate?
Intravenous steroids coupled with topical antibiotic ointment
Regularly scheduled cleansing of the woman's eyes with normal saline
Warm compresses to be applied regularly to her eyes in addition to oral
antibiotics
Surgical repair of the woman's blocked Meibomian glands
Answer- Warm compresses to be applied regularly to her eyes in
addition to oral antibiotics
A 28-year-old male who is 6 feet 11 inches tall has a diagnosis of
acromegaly. The man is explaining to a curious but sympathetic
