WGU D115 OA ADVANCED PATHOPHYSIOLOGY EXAM
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. 1 / 4

2 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 2 / 4

3 Pathogenicity Correct! Pathogenicity refers to an organism's ability to create or produce disease.The definition of legal blindness is the best corrected vision of 20/100.
True/False False Correct! 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?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. 3 / 4

4 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.
Parasympathetic preganglionic fibers release epinephrine.
Epinephrine induces general vasodilation.Dopamine is the precursor to epinephrine.
Epinephrine induces general vasodilation.
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?
Anterior horn Posterior horn Substantia gelatinosa Dorsal root ganglia
