Which term is used to describe a red-purple discoloration caused by diffuse
hemorrhage into the skin tissue?
a. Petechiae
c. Ecchymosis
b. Hematoma
d. Purpura - correct answer ANS: D
Diffuse hemorrhage into skin tissues that is visible through the skin causes a red-
purple discoloration identified as a purpura. None of the other options are used to
identify this symptom.
Which statement best describes heparin-induced thrombocytopenia (HIT)?
a. Immunoglobulin G immune-mediated adverse drug reaction that reduces circulating
platelets
b. Hematologic reaction to heparin in which the bone marrow is unable to produce
sufficient platelets to meet the body's needs
c. Immunoglobulin E-mediated allergic drug reaction that reduces circulating platelets
d. Cell-mediated drug reaction in which macrophages process the heparin and platelet
complexes that are then destroyed by activated cytotoxic T cells - correct answer ANS:
A
Heparin is a common cause of drug-induced thrombocytopenia. HIT is an immune-
mediated, adverse drug reaction caused by immunoglobulin G antibodies that leads to
increased platelet consumption and a decrease in platelet counts. None of the other
options accurately describe HIT.

[GRADE A+]
Immune thrombocytopenia (ITP) is a(n) _____ condition in adults and a(n) _____
condition in children.
a. Acute; acute
c. Acute; chronic
b. Chronic; chronic
d. Chronic; acute - correct answer ANS: D
ITP may be acute or chronic. The acute form is frequently observed in children. Chronic
ITP is more commonly observed in adults, with the highest prevalence in women
between 20 and 40 years of age.
What term is used to identify thrombi that occlude arterioles and capillaries and are
made up of platelets with minimal fibrin and erythrocytes?
a. Essential (primary) thrombocythemia (ET)
b. Acute idiopathic thrombotic thrombocytopenic purpura
c. Thrombotic thrombocytopenic purpura (TTP)
d. Immune thrombocytopenic purpura (ITP) - correct answer ANS: C
Of the available options, only TTP is characterized by thrombotic microangiopathy in
which platelets aggregate and cause occlusion of arterioles and capillaries in the
microcirculation.
Which of the following is characterized by what is referred to as pathognomonic
pentad of symptoms?
a. Acute idiopathic thrombotic thrombocytopenic purpura
