Which type of shock causes a temporary loss of motor, sensory, and reflex functions below the level of a lesion? 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? 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 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 C For a patient with chronic immune thrombocytopenia, which intervention is the initial treatment? A. Infuse intravenous immunoglobulin. B. Administer prednisone (Deltasone).

Which intervention is used to treat a patient with ventricular fibrillation who has an implantable cardiac defibrillator? Apply hands-free adhesive patches in the anterior-posterior position and defibrillate. For which disorder is phenazopyridine (Pyridium) most commonly administered? D. Urethritis Which term defines pain caused by the stretching of a hollow organ and is described as cramping or a sensation of gas? Visceral pain When a patient is in the compensatory stage of shock, the body preferentially maintains blood flow to which organs? heart and brain

Which laboratory test result should the nurse expect in a patient with alcoholic ketoacidosis? Below normal to slightly elevated serum glucose level Which finding is characteristic of preeclampsia? Proteinuria Sciatic nerve damage is associated with dislocation of which joint? A. Patellar B. Knee C. Hip D. Ankle C. Hip Which intervention is indicated for a patient with circumferential full- thickness burns of the chest, inadequate chest expansion, and restlessness?

A. Cyanide B. Kerosene C. Lead D. Potassium B Which herb can decrease the clotting time? A. Evening primrose B. Cinnamon C. Garlic D. Skull cap B. Cinnamon Which medication causes urine retention? D. Diphenhydramine (Benadryl) The ingestion of the foxglove plant can cause which finding?

A. Hypertension B. Bradycardia C. Agitation D. Lacrimation B. Bradycardia Which medication causes urine retention? D. Diphenhydramine (Benadryl) For a patient with a gunshot wound, which intervention is appropriate? A. Perform a neurovascular assessment of each limb. B. Estimate the amount of injury based on the wounds appearance. C. Remove projectiles with Kelly clamps and place them in a sterile container. D. Label the entrance and exits wounds. A. Perform a neurovascular assessment of each limb.

Which of the following statements regarding autonomic dysreflexia is correct? It may occur at any time after spinal shock has subsided. A scald burn is most likely to result from which mechanism? 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. 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 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.

Which of the following is the first step performed when removing a helmet from a suspected spinal injured patient? Apply in-line stabilization by placing hands on each side of the helmet with fingers on the patient's mandible. The administration of azithromycin (Zithromax) is indicated for which sexually transmitted infection? C. Chlamydia infection Which fracture results in multiple splintered bone fragments? A. Depressed fracture B. Impacted fracture C. Compression fracture D. Comminuted fracture D. Comminuted fracture Which sign is an indicator of cholecystitis

Murphy's sign Which disorder is a cause of cardiogenic shock? Dysrhythmias A patient with hyperosmolar hyperglycemic state is likely to have which laboratory test result? Normal blood pH Which of these is a common cause of postpartum hemorrhage? Uterine atony Which medication should be administered during the resuscitation of a patient with ventricular fibrillation? Epinephrine (Adrenalin)

D. Rho(D) immunoglobulin (RhoGAM) A. Hydroxyurea (Droxin) Which sexually transmitted infection is caused by bacteria and develops as a small bump in the genitals? A. Chancroid Which finding is a sign of serotonin syndrome? A. Bradycardia B. Diaphoresis C. Hypothermia D. Lethargy B. Diaphoresis Which sign or symptom is a characteristic of carbon monoxide poisoning?

Headache Which receptor is located in the lungs? A. Alpha B. Beta C. Beta D. Dopaminergic C. Beta2 receptors are located in the lungs and peripheral vessels. Alpha receptors exist in vascular smooth muscle. Beta1 receptors are in the myocardium. Dopaminergic receptors are found in renal, mesenteric, cerebral, and coronary arteries. A fracture of which bone does not always require anatomic alignment for healing? A. Wrist B. Hip C. Elbow D. Clavicle

Which disorder is likely to produce a delta wave on the cardiac monitor? Wolff-Parkinson-White syndrome Which of the following is the first step performed when initiating spinal protection? Leader is positioned at the head of the patient with hands on each side of the patient's head. Which dysrhythmia has premature P waves with a different configuration than other P waves in the cardiac cycle? A. Atrial flutter B. Premature atrial complex C. First-degree atrioventricular block D. Second-degree atrioventricular block, type II B. Premature atrial complexes are ectopic beats that are initiated by an irritable atrial focus. P waves are present, but because the ectopic

focus originates the impulse outside the sinoatrial node, the premature P waves have a different configuration. Atrial flutter causes no P waves, but it causes flutter waves in a sawtoothed pattern. First- degree atrioventricular block has a P wave for every QRS complex, but the PR interval is consistently prolonged. Second-degree atrioventricular block, type II, has one or more P waves for every QRS complex. In first-degree atrioventricular block and second-degree atrioventricular block, type II, the P wave configuration is consistent from P wave to P wave Nutmeg toxicity is likely to cause which finding? A. Hallucinations B. Salivation C. Rhabdomyolysis D. Seizures A In a patient with immune thrombocytopenic purpura, which finding should you expect?
