WGU D115 Unit 3Symptoms 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
