Questions Review with Complete
Solutions
Which type of shock causes a temporary loss of motor, sensory, and reflex
functions below the level of a lesion? - Ans - 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? - Ans - 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. - Ans - 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?
1
A. Opioid
Page
,B. Antidepressant
C. Anticholinergic
D. Organophosphate - Ans -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). - Ans - B. Administer
prednisone (Deltasone).
For which disorder is phenazopyridine (Pyridium) most commonly
administered? - Ans - 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 - Ans - A. Central nervous system stimulant

,Which intervention is used to treat a patient with ventricular fibrillation who
has an implantable cardiac defibrillator? - Ans - Apply hands-free
adhesive patches in the anterior-posterior position and defibrillate.
For which disorder is phenazopyridine (Pyridium) most commonly
administered? - Ans - D. Urethritis
Which term defines pain caused by the stretching of a hollow organ and is
described as cramping or a sensation of gas? - Ans - Visceral pain
When a patient is in the compensatory stage of shock, the body preferentially
maintains blood flow to which organs? - Ans - heart and brain
Which laboratory test result should the nurse expect in a patient with
alcoholic ketoacidosis? - Ans - Below normal to slightly elevated serum
glucose level
Which finding is characteristic of preeclampsia? - Ans - Proteinuria
Sciatic nerve damage is associated with dislocation of which joint?
A. Patellar
B. Knee
C. Hip
3
Page
D. Ankle - Ans - C. Hip
, Which intervention is indicated for a patient with circumferential full-
thickness burns of the chest, inadequate chest expansion, and restlessness?
- Ans - 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 - Ans - 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 - Ans -B
