CORRECT ANSWERS 2023
Symptoms of Chronic suppurative otitis media - Correct answer-Chronic suppurative
otitis media- will have hearing loss, purulent drainage, ear pain.
What is Gate Control Theory - Correct answer-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 - Correct answer-produces parathyroid
hormone (PTH)-
which is the single most important factor in the regulation of
serum calcium concentration.
What is TH responsible for - Correct answer-TH is
responsible for growth, maturation, and function of cells, body
systems throughout the body and across the life span.
Symptoms of hypothyroidism - Correct answer-decreased energy, lethargy, heat
intolerance,
lowered basal temperature, diastolic HTN, MYXEDEMA
one of the most important contributors to
insulin resistance and DM - Correct answer-Obesity
The definition of legal blindness is the best corrected vision of 20/100.
true or false - Correct answer-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 - Correct answer-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 - Correct answer-
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 - Correct 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 - Correct answer-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 - Correct answer-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 - Correct answer-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
