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).
C. Prepare the patient for a splenectomy.
D. Administer cyclophosphamide (Cytoxan). - -B. Administer prednisone
(Deltasone).
-For which disorder is phenazopyridine (Pyridium) most commonly
administered? - -D. Urethritis
-Rhabdomyolysis is a complication of which type of toxicity?

-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 - -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 - -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 disorder is associated with fatty, foul-smelling stool? - -Pancreatitis

which effect of ketoacidosis? - -Tachycardia
-In a pregnant patient, which assessment finding may signal the onset of
preeclampsia? - -A systolic blood pressure greater than 140 mm Hg
-Which dysrhythmia has an irregularly irregular ventricular response - -
Atrial fibrillation
-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
