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. Hip
, Which intervention is indicated for a patient with circumferential full-thickness burns of the
chest, inadequate chest expansion, and restlessness? - CORRECT 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 - 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?
