GUARANTEEED PASS

A 59 year old male is admitted complaining of chest pain and dyspnea. ST elevation

and T wave inversion were seen on the EKG in V2,V3 and V4. IV thrombolytic therapy

was started in ED. Indications of successful reperfusion would include all of the

following except:


(A) pain cessation


(B) decrease in CK or troponin


(C) reversal of ST segment elevation with return to baseline


(D) short runs of ventricular tachycardia - ANSWER✔✔-(B)Coronary artery reperfusion

due to PCI or fibrinolysis results in an ELEVATION of creatinine kinase (CK) or

troponin, not decrease. The theory is that the return of blood flow distal to the occlusion

can result in 'reperfusion injury' of the muscle, elevating cardiac biomarkers.


The other 3 choices are indicators of reperfusion: Pain cessation, reversal of ST segment

elevation with return to baseline, short runs of ventricular tachycardia.

,Which of the following medication orders should the nurse question for the patient in

question 1-reperfusion question-patient having an MI?


(A) metoprolol (Lopressor)


(B) aspirin


(C) propranolol (Inderal)


(D) heparin - ANSWER✔✔-(C) The patient in the scenario is having an acute anterior

wall MI. A beta blocker is beneficial for an acute MI as these agents decrease the work

of the heart and increase the threshold for ventricular fibrillation. Propranolol, although

a beta-andrenergic blocker like metoprolol, is NOT a cardioselective beta blocker. It

affects beta receptors in heart muscle AND lung tissue. Therefore, it is more likely to

cause bronchoconstriction than a cardioselective beta blocker.


The other 3- cardioselective beta blocker, antiplatelet, and anticoagulation-are indicated

in an acute MI.


If heart block develops while caring for the patient in question 1 (pt with an MI who

went through reperfusion from PCI or fibrinolytic therapy), which of the following

would it most likely be?


(A) sinoatrial block


(B) second degree, Type I


(C) second degree, Type II

, (D) third degree, complete - ANSWER✔✔-(C) The patient is having an acute anterior

MI, which is generally due to LAD occlusion. The LAD supplies the HIS bundle, which

could result in a second-degree, type II heart block. The other 3 types are due to SA

node or AV node ischemia, which generally occur with an RCA occlusion — interior

wall MI.


Appropriate drug therapy for dilated cardiomyopathy is aimed toward:


(A) decreasing contractility and decreasing preload and afterload


(B) decreasing contractility and increasing preload and afterload


(C) increasing contractility and increasing both preload and afterload


(D) increasing contractility and decreasing both preload and afterload - ANSWER✔✔-

(D) Dilated cardiomyopathy is likely to result in systolic dysfunction, which decreases

contractility, causes compensatory arterial constriction , and results in a higher left

ventricular preload. To treat this, therapy is aimed at increasing contractility, decreasing

afterload (arterial constriction), and decreasing preload that is too high.


An 18 year old is admitted with a history of syncopal episode at the mall and has a

history of an eating disorder. The nurse notes a prolonged QT on the 12-lead EKG and

anticipates a reduction in an electrolyte to be the cause. Which of the following is

LEAST likely to cause this patient's problems?


(A) sodium
