VERIFIED A+
◉ According to the rule of nines, burns of the anterior trunk and
both anterior arms account for which percentage of body surface
area? 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. 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 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). Answer: B. Administer
prednisone (Deltasone).
◉ For which disorder is phenazopyridine (Pyridium) most
commonly administered? 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 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. Patellar
B. Knee
C. Hip
D. Ankle Answer: C. Hip
◉ Which intervention is indicated for a patient with circumferential
full-thickness burns of the chest, inadequate chest expansion, and
restlessness? Answer: Escharotomy
◉ 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 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
