he is reclined. What is the probable condition causing these symptoms?
Peritonsillar abscess
Pharyngitis
Sinus infection
Allergic rhinitis - CORRECT ANS - 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 ANS - 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 ANS - 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 ANS - 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 ANS - 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 ANS - 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 - CORRECT ANS - 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? - CORRECT ANS -
