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. - ANSWER D. refractoriness, and increases peripheral vascular resistance. Hypertension is a finding in which type of poisoning? A. Opioid B. Antidepressant C. Anticholinergic D. Organophosphate - ANSWER C For a patient with chronic immune thrombocytopenia, which intervention is the initial treatment? A. Infuse intravenous immunoglobulin. B.

Calcium channel blocker - ANSWER A. Central nervous system stimulant Which intervention is used to treat a patient with ventricular fibrillation who has an implantable cardiac defibrillator? - ANSWER Apply hands-free adhesive patches in the anterior-posterior position and defibrillate. For which disorder is phenazopyridine (Pyridium) most commonly administered? - 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? - ANSWER Visceral pain When a patient is in the compensatory stage of shock, the body preferentially maintains blood flow to which organs? - ANSWER heart and brain Which laboratory test result should the nurse expect in a patient with alcoholic ketoacidosis? - ANSWER Below normal to slightly elevated serum glucose level Which finding is characteristic of preeclampsia? - ANSWER Proteinuria Sciatic nerve damage is associated with dislocation of which joint?

A. Atrial fibrillation B. Accelerated junctional tachycardia C. Second-degree atrioventricular block, type II D. 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? A. Cyanide B.

A scald burn is most likely to result from which mechanism? - ANSWER Exposure to water at 140°F (60°C) Which intervention is used to treat a patient with ventricular fibrillation who has an implantable cardiac defibrillator? A. Apply hands-free adhesive patches in the anterior-posterior position and defibrillate. B. Wait for the device to fire. C. Apply hands-free adhesive patches in the standard position and cardiovert. D. 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. Organophosphate toxicity produces which sign or symptom? A. Constipation B. Salivation C. Mydriasis D. Hot, dry skin - ANSWER B A patient with severe neutropenia has a temperature of 100.4°F (38°C). Which intervention is indicated for this patient? A. Obtain blood cultures. B. Maintain respiratory isolation. C. Administer packed red blood cells. D.
