Which type of shock causes a temporary loss of motor, sensory, and reflex functions below the level of a lesion? - correct answer Spinal shock According to the rule of nines, burns of the anterior trunk and both anterior arms account for which percentage of body surface area? - correct answer 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. - correct 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? A. Opioid B. Antidepressant C. Anticholinergic D. Organophosphate - correct answer C For a patient with chronic immune thrombocytopenia, which intervention is the initial treatment? A. Infuse intravenous immunoglobulin. B. Administer prednisone (Deltasone). C. Prepare the patient for a splenectomy. D. Administer cyclophosphamide (Cytoxan). - correct answer B. Administer prednisone (Deltasone). For which disorder is phenazopyridine (Pyridium) most commonly administered? - correct answer D. Urethritis Rhabdomyolysis is a complication of which type of toxicity? A. Central nervous system stimulant B. Opiate C. Tricyclic antidepressant D. Calcium channel blocker - correct answer A. Central nervous system stimulant Which intervention is used to treat a patient with ventricular fibrillation who has an implantable cardiac defibrillator? - correct answer Apply hands-free adhesive patches in the anterior-posterior position and defibrillate. For which disorder is phenazopyridine (Pyridium) most commonly administered? - correct answer D. Urethritis Which term defines pain caused by the stretching of a hollow organ and is described as cramping or a sensation of gas? - correct answer Visceral pain When a patient is in the compensatory stage of shock, the body preferentially maintains blood flow to which organs? - correct answer heart and brain Which laboratory test result should the nurse expect in a patient with alcoholic ketoacidosis? - correct answer Below normal to slightly elevated serum glucose level Which finding is characteristic of preeclampsia? - correct answer Proteinuria Sciatic nerve damage is associated with dislocation of which joint? A. Patellar B. Knee C. Hip D. Ankle - correct answer C.

A. Atrial fibrillation B. Accelerated junctional tachycardia C. Second-degree atrioventricular block, type II D. Polymorphic ventricular tachycardia - correct 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? A. Cyanide B. Kerosene C. Lead D. Potassium - correct answer B Which herb can decrease the clotting time? A. Evening primrose B. Cinnamon C. Garlic D. Skull cap - correct answer B. Cinnamon Which medi
