In a patient with left heart failure and pulmonary edema:
A. diffusely collapsed alveoli cause blood from the right side of the heart to bypass the
alveoli and return to the left side of the heart deoxygenated
B. an acute myocardial infarction or chronic hypertension causes the left ventricle to
pump against decreased afterload, resulting in hypoperfusion.
C. increased pressure in the left atrium and pulmonary veins forces serum out of the
pulmonary capillaries and into the interstitial lung tissue and the alveoli.
D. the right atrium and ventricle pump against lower pressures, resulting in the systemic
pooling of venous blood. - answer>>>C. increased pressure in the left atrium and
pulmonary veins forces serum out of the pulmonary capillaries and into the interstitial
lung tissue and the alveoli.
In addition to supplemental oxygen, treatment of a patient with left-sided heart failure
includes:
A. a saline lock, fentanyl, and intubation facilitated by pharmacologic agents.
B. an IV of normal saline, a 20-mL/kg fluid bolus, and a diuretic medication.
C. an IV of normal saline to keep the vein open, nitroglycerin, and morphine or CPAP.
D. a saline lock, a selective beta-2 adrenergic medication, and a corticosteroid. -
answer>>>C. an IV of normal saline to keep the vein open, nitroglycerin, and morphine
or CPAP.
In contrast to arteries, veins:
A. have a lesser capacity to increase the size of their diameter.
B. operate on the high-pressure side of the circulatory system.
C. do not contain valves that prevent the backflow of blood.
D. are more likely to distend when exposed to backpressure. - answer>>>D. are
more likely to distend when exposed to backpressure.

,In contrast to coarse ventricular fibrillation, fine ventricular fibrillation indicates that:
A. the energy reserves of the cardiac cells have been expended.
B. the arrhythmia is more likely to respond to defibrillation.
C. the cardiac cells temporarily have adequate energy stores that may allow for a
perfusing rhythm following synchronized cardioversion
D. a perfusing rhythm is likely possible following defibrillation. - answer>>>A. the
energy reserves of the cardiac cells have been expended.
In comparison to stable angina, unstable angina:
A. usually occurs following periods of strenuous exertion.
B. may awaken the patient from his or her sleep.
C. is less frequent but is also associated with more severe pain.
D. indicates that myocardial necrosis has occurred. - answer>>>B. may awaken
the patient from his or her sleep.
In contrast to the pain associated with an acute myocardial infarction, pain from a
dissecting aortic aneurysm:
A. over time, gradually becomes severe.
B. is most intense from the onset.
C. often waxes and wanes effect
D. is usually preceded by other symptoms prior to the onset of pain - answer>>>B. is
most intense from the onset.
Monomorphic ventricular tachycardia:
A. is often irregular with occasional nonconducted P waves.
B. presents with wide QRS complexes that possess common shape, size, and deflection.
C. is treated as ventricular fibrillation if a pulse is present.
D. is characterized by QRS complexes that vary in size, shape, and deflection. -
answer>>>B. presents with wide QRS complexes that possess common shape, size,
and deflection.

, Normal sinus rhythm is characterized by all of the following, EXCEPT:
A. consistent PR intervals and upright P waves.
B. a heart rate, symbolized by QRS complexes above 100 complexes per minute.
C. a consistent heart rate between 60 and 100 complexes per minute.
D. a minimal variation between the R-R intervals. - answer>>>B. a heart rate,
symbolized by QRS complexes above 100 complexes per minute.

A. depressed by no more than 2 mm.
B. invisible on a normal ECG tracing.
C. at the level of the isoelectric line.
D. elevated by no more than 1 mm. - answer>>>C. at the level of the isoelectric line.
