Which leukocytes are elevated in response to acute inflammatory reactions when considering
white blood cell differentials?
Basophils
Eosinophils
Neutrophils
Monocytes
Neutrophils
Correct! Neutrophils are one of the first responders to acute inflammation, and an increase in
neutrophils demonstrates an acute inflammatory response.
Which type of immunity is produced by an individual after either natural exposure to the
antigen or after immunization against the antigen?
Passive-acquired immunity
Passive-innate immunity
Active-acquired immunity
Active-innate immunity
Active-acquired immunity
Correct! Active-acquired immunity or naturally acquired active immunity occurs when an
individual is exposed to a live pathogen and develops the disease or becomes immune as a
result of a vaccine.

Which characteristics do atopic individuals have that make them genetically predisposed to
develop allergies?
Deficiency in epinephrine
Greater quantities of IgE
More histamine receptors
Greater quantities of histamine
Greater quantities of IgE
Correct! The greater quantities of IgE in atopic individuals make them genetically predisposed
to develop allergies. IgE mediates the immune response to allergens; therefore, the more IgE
one has, the stronger the response can be to an allergen. Think of it as having more soldiers in
the army to fight the war.
A healthcare professional is conducting community education on vaccinations.
Which statement about vaccines should the professional include in the presentation?
Most viral vaccines are made by using dead organisms.
Most bacterial vaccines contain attenuated organisms.
Vaccines require booster injections to maintain life-long protection.
Vaccines provide effective protection against most infections.
Vaccines require booster injections to maintain life-long protection.
Correct! Most vaccines require a booster to increase immunity. The initial effects of a vaccine
may diminish over time, and boosters improve protection against disease.
Which term describes an agent's ability to produce disease?
Immunogenicity
Pathogenicity
Virulence
Infectivity

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?
Pharyngitis
Peritonsillar abscess
Sinus infection
Allergic rhinitis
Allergic rhinitis
Correct! 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.
Your patient presents with head congestion for seven days with a temperature of 102°F and a
very painful throat. Upon examination, you discover maxillary sinus tenderness, enlarged
tonsils, and heavy oropharyngeal exudate. You do a CBC and see the WBC is 15. Your patient
is very ill with both sinusitis and exudative pharyngitis. Now comes the challenge of further
diagnostic tests and treatment, plus the worry over the amount of swelling in the left tonsil.
Could it be an abscess?
Explain why the patient described could or could not have a tonsillar abscess and provide a
rationale.

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?
Dopamine is the precursor to epinephrine.
The action of epinephrine is the same no matter which receptor it binds to.
Correct! 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?
