account for which percentage of body surface area? - ANSWER 27 percent
Which effect does parasympathetic stimulation have on the heart?
• It increases peripheral vascular resistance.
• It enhances atrioventricular node function.
• It shortens His-Purkinje and ventricular muscle refractoriness.
• It slows sinoatrial node discharge. - ANSWER D.
Parasympathetic stimulation slows sinoatrial node discharge. Sympathetic stimulation
enhances atrioventricular node function, shortens His-Purkinje and ventricular muscle
refractoriness, and increases peripheral vascular resistance.
Hypertension is a finding in which type of poisoning?
• Opioid
• Antidepressant
• Anticholinergic

Calcium channel blockers are indicated to treat which dysrhythmia?
• Atrial fibrillation
• Accelerated junctional tachycardia
• Second-degree atrioventricular block, type II
• Polymorphic ventricular tachycardia - ANSWER A.
Treatment of atrial fibrillation aims to control the rapid ventricular rate with medications,
such as calcium channel blockers or beta-blockers. Calcium channel blockers are not
used to treat the other dysrhythmias listed. Accelerated junctional tachycardia is a
transient rhythm that only requires treatment of the underlying disorder. Patients with
second-degree atrioventricular block, type II, require careful monitoring and may need
transcutaneous pacing. Treatment for polymorphic ventricular tachycardia is
magnesium sulfate and defibrillation if the patient's condition is unstable.
,Activated charcoal can absorb which substance?
• Cyanide
• Kerosene

Which intervention is applied to a ventricular fibrillation patient who has an implanted
cardiac defibrillator?
• Apply hands-free adhesive patches in the anterior-posterior position and
defibrillate.
• Wait for the device to fire.
• Apply hands-free adhesive patches in the standard position and cardiovert.
• Apply one hands-free adhesive patch over the device and the other on the
opposite side of the sternum and defibrillate. - ANSWER A.
When a patient with an implantable cardiac defibrillator requires external defibrillation
because the implanted device has malfunctioned or failed, ideally place hands-free
adhesive patches in the anterior-posterior position. Do not wait for the device to fire
because a malfunction has occurred if ventricular fibrillation is present. Cardioversion is
not appropriate because no QRS complexes are present for synchronization. Do not
place the adhesive patches directly over the implantable cardiac defibrillator.

• Salivation
• Mydriasis
