the:
A) ventricles
B) atrium

A) Formation of fibrin
B) The intrinsic and extrinsic pathways
C) Aggregation of platelets

6) On the 12 lead ECG, the QTc:
A) is the QT interval corrected for heart rate.
B) is normally greater than 350 ms.
C) cannot be determined in rapid rates over 150 bpm.
D) is an important determinant of myocardial contractility - answer>>>A) is the QT
interval corrected for heart rate.
7) Select the best dose of Tridil (R) for a patient with left sided congestive heart failure
and an initial blood pressure of 180/110:
A) 50 mcg/min
B) 5-10 mcg/kg/min
C) 50 mcg/kg/min
D) 0.5 mcg/min - answer>>>A) 50 mcg/min
8) To determine left ventricular hypertrophy, you should:
A) Count the mm of amplitude in the deepest of V1 or V2, plus mm of amplitude in the
taller of V5 or V6, and add them; if greater than 35, LVH may be present.
B) Count the small boxes of depth in V1 and the small boxes of height in V6 and add
them; if the sum is greater than 35, LVH may be present.
C) Count the mm of amplitude in V1 and V2 and add them; count the mm of amplitude
in V5 and V6 and add them; subtract the two numbers; if the difference is more than 35,
LHV may be present.
D) Assess the major deflection of the R wave in V1 and V6; if they are opposite and
amplitudes are equal, LVH may be present. - answer>>>A) Count the mm of amplitude
in the deepest of V1 or V2, plus mm of amplitude in the taller of V5 or V6, and add
them; if greater than 35, LVH may be present.
9) Which of the following are necessary when setting up a nitroglycerin infusion?

C) Reciprocal changes include development of Q waves in leads V4-V6.
D) Reciprocal changes can not be reversed by administration of nitrates. - answer>>>A)
STEMI imitators do not produce reciprocal changes
