ST segment monitoring for ischemia has gained increasing importance with the
advent of thrombolytic therapy. The most accurate method for monitoring the
existence of true ischemic changes is
T-wave inversion in leads overlying the ischemia.
ST segment depression in leads overlying the ischemia.
adjusting the gain control on bedside monitoring for best visualization.
12-lead ECG for confirmation.
12-lead ECG for confirmation.
A patient with ventricular fibrillation (VF) is
hypertensive.
bradypneic.
diaphoretic.
pulseless.

Contractility of the left side of the heart is measured by
pulmonary artery wedge pressure.

A 52-year-old patient presents to the emergency department with reports of
substernal chest pain. A history is taken; serum creatine kinase (CK) and lactate
dehydrogenase (LDH) isoenzymes and serum lipid studies are ordered, as is a 12-
,lead ECG. Which of the following results is most significant in diagnosing an MI
during the first 12 hours of chest pain?
ECG—inverted T waves
Serum enzymes—elevated LDH4
Serum enzymes—elevated CK-MB
Patient history—substernal chest pain
Serum enzymes—elevated CK-MB
Which serum lipid value is a significant predictor of future acute MI in persons with
established coronary artery atherosclerosis?
High-density lipoprotein (HDL)
Low-density lipoprotein (LDL)
Triglycerides
Very-low-density lipoprotein
Low-density lipoprotein (LDL)
A patient with a potassium level of 2.8 mEq/L is given 60 mEq over a 12-hour
period, and a repeat potassium level is obtained after the bolus. The current
potassium level is 2.9 mEq/L. Which of the following should now be considered?
Stopping the patient's Aldactone
Drawing a serum magnesium level
Rechecking the potassium level
Monitoring the patient's urinary output
Drawing a serum magnesium level
Which of the following cardiac enzymes is a highly specific biomarker for
myocardial damage?
CK-MB
Troponin I
,Troponin T
LDH
Troponin I
Identify the rhythm.
Ventricular tachycardia
Ventricular fibrillation
Supraventricular tachycardia
Torsades de pointes
Ventricular fibrillation
Data concerning coronary artery disease (CAD) and specific risk factors have
demonstrated
a low correlation of modifiable risk factors to CAD.
the onset of CAD in middle age.
an association between development of specific risk factors and CAD.
no decisive correlation between risk factors and CAD.
an association between development of specific risk factors and CAD.
Which of the following values, when elevated, places the patient at lowest risk for
CAD?
Very-low-density lipoproteins (VLDLs)
Triglycerides
Low-density lipoproteins (LDLs)
High-density lipoproteins (HDLs)
High-density lipoproteins (HDLs)
, Nursing management of the patient with angina is directed toward
immediate administration of antiplatelet therapy.
assessment of history of previous anginal episodes.
assessment and documentation of chest pain episodes.
administration of prophylactic lidocaine for ventricular ectopy.
assessment and documentation of chest pain episodes.
One of the reasons that contributes to higher mortality rates from acute MI in
women is:
waiting longer to seek medical care.
being younger when symptoms occur.
risk factors associated with MI are more stronger in women than men.
women have smaller hearts than men.
waiting longer to seek medical care.
Clinical manifestations of right-sided heart failure include
elevated central venous pressure and sacral edema.
pulmonary congestion and jugular venous distention.
hypertension and chest pain.
liver tenderness and pulmonary edema.
elevated central venous pressure and sacral edema.
An essential aspect of teaching that may prevent recurrence of heart failure is
notifying the physician if a 2-lb weight gain occurs in 24 hours.
compliance with diuretic therapy.
taking nitroglycerin if chest pain occurs.
assessment of an apical pulse.
compliance with diuretic therapy.
The nurse should anticipate which of the following as the most common
complication after an MI?
Pulmonary edema
