Answers)
Symptoms of Chronic suppurative otitis media
Chronic suppurative otitis media- will have hearing loss, purulent drainage, ear pain.
What is Gate Control Theory
pain transmission is modulated by a balance of impulses conducted to the spinal cord
where cells in the
substantia gelatinosa function as a "gate".
What is the parathyroid gland responsible for
produces parathyroid hormone (PTH)-
which is the single most important factor in the regulation of
serum calcium concentration.
What is TH responsible for
TH is
responsible for growth, maturation, and function of cells, body
systems throughout the body and across the life span.
Symptoms of hypothyroidism
decreased energy, lethargy, heat intolerance,
lowered basal temperature, diastolic HTN, MYXEDEMA
one of the most important contributors to
insulin resistance and DM
Obesity
The definition of legal blindness is the best corrected vision of 20/100.
true or false
FALSE
The definition of legal blindness is the best corrected vision of 20/200.
A male patient presents with sinus congestion, clear nasal discharge, and a cough that
is worse when he is reclined.
What is the probable condition causing these symptoms?
Peritonsillar abscess
Pharyngitis
Sinus infection
Allergic rhinitis
Allergic rhinitis is marked by sinus congestion, clear nasal discharge, post nasal drip
that causes a sore throat, and cough that is worse when supine.
unilateral tonsillar enlargement during acute tonsillitis is suggestive of
Unilateral tonsillar enlargement during acute tonsillitis is suggestive of a tonsillar
abscess. If the patient does not have trouble swallowing, is drooling, or has a muffled
voice, then it could be an enlarged tonsil rather than an abscess. Because of the risk of
airway obstruction, it is imperative that tonsillar abscess is ruled out during the
assessment.
Which two statements are true regarding epinephrine?
, Parasympathetic preganglionic fibers release epinephrine.
Epinephrine induces general vasodilation.
The action of epinephrine is the same no matter which receptor it binds to.
Dopamine is the precursor to epinephrine.
Check My Answer
Dopamine is the precursor of both epinephrine and norepinephrine.
Epinephrine induces general vasodilation because of the predominance of β-adrenergic
receptors in the muscle vasculature.
Which structure is specifically involved in pain transmission?
Posterior horn
Dorsal root ganglia
Anterior horn
Substantia gelatinosa
The substantia gelatinosa, which is at the tip of the posterior horn of the spinal cord, is
directly involved in pain transmission.
Previousquestion
Which mechanism of heat loss involves electromagnetic waves?
Convection
Radiation
Conduction
Evaporation
Radiation is heat loss due to magnetic waves from surfaces of higher temperatures to
ambient air that is cooler.
Which theory of pain best describes phantom limb pain?
Pattern theory
Gate control theory
Neuromatrix theory
Specificity theory
The neuromatrix theory proposes that the brain produces patterns of nerve impulses
drawn from various inputs, such as genetic, psychological, and cognitive experiences,
and suggests that pain may be felt in the absence of input from the body. This theory
would explain the phantom limb pain the woman is experiencing.
What is the most critical aspect of correctly diagnosing a seizure disorder and
establishing its cause?
Cerebrospinal fluid analysis
Computed tomographic (CT) scan
Health history
Skull X-ray studies
Exploring health history is critical in an individual with a seizure disorder. The history
often provides information such as childhood seizures or a previous head injury which
leads to the definitive diagnosis. The history also guides further testing to determine if
systemic causes might be producing seizure activity.
Which symptoms exhibited by a patient are consistent with Alzheimer disease?
memory loss, impaired judgment, personality changes, and a reduced ability to care for
herself.
why it is important to ask about a family history of Alzheimer disease.
