ENA Emergency Nursing Orientation 3.0
Which type of shock causes a temporary loss of motor, sensory, and reflex functions below the
level of a lesion? - correct anwersSpinal 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 anwers27 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 anwersD.
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 anwersC
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 anwersB. Administer prednisone
(Deltasone).
For which disorder is phenazopyridine (Pyridium) most commonly administered? - correct
anwersD. 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 anwersA. Central nervous system stimulant
Which intervention is used to treat a patient with ventricular fibrillation who has an implantable
cardiac defibrillator? - correct anwersApply hands-free adhesive patches in the anterior-
posterior position and defibrillate.
For which disorder is phenazopyridine (Pyridium) most commonly administered? - correct
anwersD. Urethritis
Which term defines pain caused by the stretching of a hollow organ and is described as
cramping or a sensation of gas? - correct anwersVisceral pain
When a patient is in the compensatory stage of shock, the body preferentially maintains blood
flow to which organs? - correct anwersheart and brain
Which laboratory test result should the nurse expect in a patient with alcoholic ketoacidosis? -
correct anwersBelow normal to slightly elevated serum glucose level
Which finding is characteristic of preeclampsia? - correct anwersProteinuria
Sciatic nerve damage is associated with dislocation of which joint?
A. Patellar
, B. Knee
C. Hip
D. Ankle - correct anwersC. Hip
Which intervention is indicated for a patient with circumferential full-thickness burns of the
chest, inadequate chest expansion, and restlessness? - correct anwersEscharotomy
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 - correct anwersA.
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 anwersB
Which herb can decrease the clotting time?
A. Evening primrose
B. Cinnamon
