Q1 QUESTION 1 OF 103
First degree heart block
CORRECT ANSWER
Atrioventricular (AV) block in which the atrial electrical impulses are delayed by a fraction of a second before being conducted to
the ventricles
RATIONALE
Atrioventricular (AV) block occurs when there is a prolonged conduction time of electrical impulses from the atria to the ventricles,
specifically characterized by a consistent PR interval exceeding 200 milliseconds on an ECG. This delay signifies impaired electrical
conduction without missed beats, distinguishing first-degree block from more severe types of AV block.
Q2 QUESTION 2 OF 103
Normal Interval for PR Interval
CORRECT ANSWER
0.12-0.2 sec
Page 2
, RATIONALE
2 seconds indicates normal conduction through the atria and the atrioventricular node, reflecting effective electrical propagation from
atrial depolarization to ventricular depolarization. Deviations from this range can signify underlying conduction abnormalities, such as
first-degree AV block or more severe forms of heart block.
Q3 QUESTION 3 OF 103
Idiopathic (Immune) Thrombocytopenic Purpura (ITP)
CORRECT ANSWER
Disorder that follows a Viral infection, causing bleeding in gums/from nose, petechial rash, and increased bleeding time.
RATIONALE
ITP is characterized by an autoimmune response triggered by viral infections, leading to the destruction of platelets and resulting in
symptoms such as bleeding gums, epistaxis, and petechiae, all indicative of thrombocytopenia. Increased bleeding time reflects
impaired hemostasis due to the reduced platelet count.
Q4 QUESTION 4 OF 103
Pathophysiology of immune thrombocytopenia purpura
CORRECT ANSWER
Plasma cells produce autoantibodies (IgG) against platelet antigens (GPIIb/GPIIIa) leading destruction of platelets.
Page 3
, RATIONALE
Autoantibodies, specifically IgG, target glycoprotein IIb/IIIa complexes on platelets, resulting in their destruction primarily by splenic
macrophages, thereby causing thrombocytopenia. This mechanism underscores the autoimmune nature of immune thrombocytopenic
purpura, highlighting the pivotal role of the adaptive immune response in platelet regulation.
Q5 QUESTION 5 OF 103
Lab findings for ITP (4)
CORRECT ANSWER
Immune Thrombocytopenia Purpura
Decreased platelets, Normal Pt/PTT,
Increased bleeding time,
Increased Megakaryocytes (destruction is outside of bone marrow)
RATIONALE
Decreased platelets in Immune Thrombocytopenic Purpura (ITP) result from peripheral destruction rather than reduced production,
evidenced by increased megakaryocytes in the bone marrow. Normal PT and PTT indicate that the coagulation cascade remains intact,
while prolonged bleeding time reflects platelet dysfunction and reduced numbers.
