Seasonal allergic rhinitis is most involved in type II hypersensitivity reactions.
Selected a. Fals
Answer: e
Correct a. Fals
Answer: e
Response Seasonal allergic rhinitis is most involved in type I
Feedback: hypersensitivity reactions.
 Question 2
0.05 out of 0.05 points
Two primary acid-base disorders that are present independently are referred to
as
Selected b. mixed acid-base
Answer: imbalance.
Correct b. mixed acid-base
Answer: imbalance.
Response Mixed acid-base disorders occur when two primary acid-base disorders are
Feedback: present independently. They may arise from simultaneous dysfunction of
the respiratory system and kidneys. Metabolic acidosis is an acid disorder.
Metabolic alkalosis and respiratory alkalosis are base disorders.

Secondary injury after head trauma refers to
Selected d. brain injury resulting from the body’s response to
Answer: tissue damage.
Correct d. brain injury resulting from the body’s response to
Answer: tissue damage.
Response Secondary injury is a consequence of the body’s response to the primary
Feedback: injury. Injury that is directly related to the initial impact is primary injury. A
focal area of bleeding is related to primary injury. Injury that results from
medical therapy is not known as secondary injury.
 Question 4
0.05 out of 0.05 points
Overproduction of nitric oxide is an important aspect of the pathophysiologic
process of what type of shock?
Selected c. Sept
Answer: ic

, Correct c. Sept
Answer: ic
Response The overproduction of nitric oxide is seen in septic shock as a result of the
Feedback: release of immune cytokines. Nitric oxide is not seen in cardiogenic shock.
Hypovolemic shock is not associated with the overproduction of nitric acid.
The pathophysiologic process of anaphylactic shock is not associated with
the overproduction of nitric oxide.
 Question 5
0.05 out of 0.05 points
Widespread activation of the clotting cascade secondary to massive trauma is
called
Selected a. disseminated intravascular
Answer: coagulation (DIC).
Correct a. disseminated intravascular
Answer: coagulation (DIC).
Response Widespread clotting in small vessels leads to consumption of the clotting
Feedback: factors and platelets, which in turn leads to bleeding. DIC is either acute or
chronic and occurs secondary to malignancy, sepsis, snake bites, trauma,
shock, burns, and many other factors. Hemophilia B results from factor
deficiency or the abnormal function of factor IX. Massive trauma is
unrelated to the development of Hageman disease. Immune
thrombocytopenia, formerly called idiopathic thrombocytopenia purpura, is
an acquired immune-mediated disorder.
 Question 6
0.05 out of 0.05 points
A type of insulin that would be most appropriate for acute management of
hyperglycemia is
Selected a. regul
Answer: ar.
Correct a. regul
Answer: ar.
Response Regular insulin is short-acting and would be used for acute hyperglycemia.
Feedback: NPH insulin is an intermediate-acting agent which would not be useful in
acute hyperglycemia. Acute management of hyperglycemia is not
accomplished with Semilente insulin. Ultralente insulin is not the most
appropriate treatment for acute hyperglycemia.
 Question 7
0.05 out of 0.05 points
Inflammation of the sacs that overlie bony prominences is called
Selected d. bursiti
Answer: s.
Correct d. bursiti
Answer: s.
Response Bursitis is inflammation of the bursal sacs that protect the skin over bony
Feedback: protuberances. Epicondylitis is inflammation of an epicondyle. Arthritis is

, inflammation of one or more joints. Tendinitis is inflammation of a tendon.
 Question 8
0.05 out of 0.05 points
________ occurs when a brainstem impaired patient exhibits a persistent
rhythmic or jerky movement in one or both eyes.
Selected b. Nystagm
Answer: us
Correct b. Nystagm
Answer: us
Response Nystagmus is a persistent rhythmic or jerky movement in one or both eyes.
Feedback: Dysconjugate movements occur when the eyes do not move together in
the same direction. Ocular palsies occur when one or more cranial nerves
are dysfunctional such that motor paralysis of the eye muscles impairs
movements in one or more directions. The doll’s-eyes test is performed by
holding open the patient’s eyelids and rotating the head from one side to
the other. If the brainstem is intact, the eyes will turn in a direction
opposite to the direction of head rotation.
 Question 9
0.05 out of 0.05 points
Angina caused by coronary artery spasm is called _____ angina.
Selected b. Prinzmetal
Answer: variant
Correct b. Prinzmetal
Answer: variant
Response Variant, or Prinzmetal, angina is the term applied to vasospasm-
Feedback
:
initiated anginal symptoms caused by significant atherosclerotic
plaques. These spasms usually respond promptly to vasodilating
agents. Coronary artery spasm does not produce stable angina.
Classic or typical angina is often associated with physical exertion.
Unstable angina presents a similar clinical picture as myocardial
infarction.
 Question 10
0.05 out of 0.05 points
The ________ is the level of painful stimulation required to be perceived.
Selected c. thresho
Answer: ld
Correct c. thresho
Answer: ld
Response Pain threshold is the level of painful stimulation required to be perceived
Feedback: and is remarkably similar from one individual to another. Perception
includes an awareness and interpretation of the meaning of the sensation.
Pain perception is influenced by attention, distraction, anxiety, fear,
fatigue, and previous experience and expectations. Pain tolerance is the
degree of pain that one is willing to bear before seeking relief. Pain
tolerance varies widely among individuals and within the same individual
