According to the rule of nines, burns of the anterior trunk and both anterior arm
percentage of body surface area?
27 percent
Which effect does parasympathetic stimulation have on the heart? A. It
increases peripheral vascular resistance.
B. It enhances atrioventricular node function.
C. It shortens His-Purkinje and ventricular muscle refractoriness.
D. It slows sinoatrial node discharge.
D.
Parasympathetic stimulation slows sinoatrial node discharge. Sympathetic stimulation
node function, shortens His-Purkinje and ventricular muscle refractoriness, and increa
resistance.

D. Urethritis
Which term defines pain caused by the stretching of a hollow organ and is desc
sensation of gas?
Visceral pain
When a patient is in the compensatory stage of shock, the body preferentially m
which organs? heart and brain
Which laboratory test result should the nurse expect in a patient with alcoholic
Below normal to slightly elevated serum glucose level
Which finding is characteristic of preeclampsia?
Proteinuria
,Calcium channel blockers are indicated to treat which dysrhythmia?
A. Atrial fibrillation
B. Accelerated junctional tachycardia
C. Second-degree atrioventricular block, type II
D. Polymorphic ventricular tachycardia
A.
Treatment of atrial fibrillation aims to control the rapid ventricular rate with medications
blockers or beta-blockers. Calcium channel blockers are not used to treat the other dy
Accelerated junctional tachycardia is a transient rhythm that only requires treatment o
Patients with second-degree atrioventricular block, type II, require careful monitoring a
transcutaneous pacing. Treatment for polymorphic ventricular tachycardia is magnesi
