Among patients with contact burns, which body region is the most common injury
site? - ANSWER- Palm of the hand
Volkmann's contracture may be a complication of which fracture?

D. Clavicular fracture - ANSWER- B. Elbow fracture
Which is the main electrolyte disturbance in rhabdomyolysis? - ANSWER- C.
Hyperkalemia
What is the cardinal sign of lower gastrointestinal bleeding? - ANSWER-
hematochezia
Which type of shock is typically associated with acute spinal cord disruption from
trauma or spinal anesthesia? - ANSWER- Neurogenic shock
Which medications can precipitate a hyperosmolar hyperglycemic state? -
ANSWER- Diuretics
For a patient with an obstetric emergency, what are the priorities during the initial
,assessment? - ANSWER- Airway, breathing, and circulation
A preexcitation syndrome, such as Wolff-Parkinson-White syndrome, results from
which conduction pattern? - ANSWER- Atrial impulses bypass the typical
electrical pathway and activate the ventricular myocardium directly.
For a patient with partial airway obstruction who cannot tolerate the supine
position for spinal stabilization, which intervention is appropriate? - ANSWER-
Protect the cervical spine in the position the patient uses to protect the airway.
Which method delivers nonsynchronous energy to the myocardium?
A. Transcutaneous pacing
B. Cardioversion C. Defibrillation
D. Transvenous pacing - ANSWER- C.
Defibrillation is the nonsynchronous delivery of energy to the heart during any
phase of the cardiac cycle. The intent of this energy delivery is to simultaneously
depolarize all of the heart cells, interrupting the abnormal electrical rhythm and
allowing the sinoatrial node to resume its normal pacemaker activity. In
synchronized cardioversion, energy delivery is timed to correspond with the QRS
complex to avoid shock delivery during the relative refractory period, which can
induce ventricular fibrillation. Transcutaneous and transvenous pacemakers
electrically stimulate a heartbeat when the heart's intrinsic electrical system cannot
generate a rate that is adequate to support cardiac output.
Which type of toxicity causes hyperglycemia?
A. Methanol
B. Ethanol
C. Isopropanol
D. Ethylene glycol - ANSWER- C
Which disorder is an inherited disease?
A. Syndrome of inappropriate antidiuretic hormone
B. Acute idiopathic thrombocytopenic purpura
C. Acute leukemia
,D. Sickle cell disease - ANSWER- D. Sickle cell disease
Which disorder causes unbearable pain due to increased pressure and dilation of
the kidney? - ANSWER- B. Prostatitis
For which drugs can you obtain blood levels to determine toxicity?
A. Morphine and
hydrocodone (Vicodin)
B. Marijuana and
cocaine
C. Acetaminophen (Tylenol) and
digoxin (Lanoxin)
D. Diazepam (Valium) and midazolam (Versed) -
ANSWER- C. Acetaminophen
(Tylenol) and digoxin
(Lanoxin)
Which hourly amount of intravenous fluid should the nurse administer to a 75-kg
patient with a significant electrical burn? - ANSWER- 1,500 mL/hour
Which intervention is indicated for a patient with an amputation?
A. Maintain the limb in the correct anatomic position.
B. Clean the amputated part with povidone-iodine (Betadine) solution.
C. Soak the stump in distilled water.
D. Place the amputated part directly in ice. - ANSWER- A. Maintain the limb in
the correct anatomic position.
Which disorder causes unbearable pain due to increased pressure and dilation of
the kidney? - ANSWER- B. Prostatitis
A woman, age 27, presents to your emergency department with chills, fever,
abdominal pain, nausea, vomiting, and tachycardia. The abdominal pain becomes
localized in her right lower quadrant. What is your priority intervention? -
ANSWER- Initiate intravenous access.
, Which statement accurately characterizes shock in a pregnant patient? -
ANSWER- The risk of fetal distress exists despite maternal stability.
The inadequate or impaired secretion of antidiuretic hormone (ADH [vasopressin])
causes which endocrine emergency? - ANSWER- Diabetes insipidus
A patient reports that she had a positive pregnancy test 1 week ago and now has
left lower quadrant pain, which was severe and then seemed to get better. On
assessment, you note that she has a weak radial pulse, tachycardia, and pallor.
Which intervention should you anticipate as the priority? - ANSWER- Establish
vascular access.
A patient has stable, monomorphic ventricular tachycardia. To perform
synchronized cardioversion with a biphasic defibrillator and convert this
dysrhythmia, which energy setting should be used first? - ANSWER- 100 joules A
paraplegic patient comes to the ED with a severe headache and blurred vision.
Findings include a flushed face, severe hypertension, and bradycardia. What is the
most likely cause of these signs and symptoms? - ANSWER- Constipation
Which medication should be administered during the resuscitation of a patient with
ventricular fibrillation? A. Ibutilide (Corvert)
B. Procainamide (Pronestyl)
C. Epinephrine (Adrenalin)
D. Sotalol (Betapace) - ANSWER- C.
During the resuscitation of a patient with ventricular fibrillation, administer
intravenous epinephrine (Adrenalin) or vasopressin (Pitressin) to enhance the
effectiveness of the cardiopulmonary resuscitation. Procainamide (Pronestyl) or
sotalol (Betapace) may be prescribed for a patient with stable ventricular
tachycardia. Ibutilide is used to convert new-onset atrial fibrillation.
A man, age 75, presents with blurred vision, flushing, fever, tachycardia, and urine
retention. These manifestations suggest which toxidrome?
A. Anticholinergic
B. Opioid
C. Sympathomimetic
