1. Symptoms of Chronic suppurative otitis media: Chronic suppurative otitis media- will have
hearing loss, purulent drainage, ear pain.
2. 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".
3. 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.
4. 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.
5. Symptoms of hypothyroidism: decreased energy, lethargy, heat intolerance,
lowered basal temperature, diastolic HTN, MYXEDEMA
6. one of the most important contributors to
insulin resistance and DM: Obesity
7. 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.
8. 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.
9. unilateral tonsillar enlargement during acute tonsillitis is suggestive of: Uni-
lateral 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.

10. 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.
11. 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
12. 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.
13. 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.
14. What is the most critical aspect of correctly diagnosing a seizure disorder
and establishing its cause?
