COMPREHENSIVE EMERGENCY DEPARTMENT
NURSING CERTIFICATION EXAMINATION
200 Advanced Clinical Questions with Detailed Rationales
Question 1
A nurse in an emergency department is caring for an 8-year-old
child who is fully up-to-date with current childhood immunization
recommendations and presents with a deep, contaminated puncture
wound. Which of the following actions should the nurse anticipate
taking?
A) Administer tetanus toxoid-containing vaccine (DTaP/Tdap)
immediately.
B) Administer tetanus immune globulin (TIG) and tetanus toxoid
vaccine.
C) Cleanse the wound thoroughly; no tetanus booster or TIG is
required.
D) Administer pediatric diphtheria and tetanus toxoids (DT) only.
Correct Answer: C
Detailed Rationale: Rationale: According to CDC guidelines,
children who are fully up-to-date on their routine immunizations
(DTaP series completed, with boosters appropriate for age) do not
require a tetanus toxoid booster or tetanus immune globulin (TIG)
for a clean or contaminated wound unless it has been more than 5
years since their last dose. For an 8-year-old who is up-to-date,
their last booster (the 4th dose of DTaP) is typically given between
,4-6 years of age, meaning they are well within the 5-year window
for contaminated wounds (which requires a booster only if >5
years, whereas clean wounds require >10 years).
Question 2
An adult patient arrives at the emergency department following a
high-speed motor vehicle collision. The patient is confused, pale,
diaphoretic, has a blood pressure of 82/50 mmHg, a heart rate of
132 bpm, and absent breath sounds on the right side with tracheal
deviation to the left. Which of the following is the immediate
priority intervention?
A) Immediate administration of 2 units of uncrossed O-negative
blood.
B) Needle decompression of the right chest followed by chest tube
insertion.
C) Rapid sequence intubation and mechanical ventilation.
D) Focused Assessment with Sonography for Trauma (FAST)
exam.
Correct Answer: B
Detailed Rationale: Rationale: The patient exhibits classic signs of
a tension pneumothorax (hypotension, tachycardia, respiratory
distress, absent breath sounds on the affected side, and tracheal
deviation). A tension pneumothorax is an immediate life-
threatening condition that causes obstructive shock by compressing
mediastinal structures. It requires immediate needle decompression
(typically with a 14-gauge needle in the 2nd intercostal space at the
midclavicular line or 5th intercostal space at the anterior/mid-
axillary line) prior to definitive chest tube placement. Waiting for
,diagnostics like a FAST exam or blood administration would be
fatal.
Question 3
A 65-year-old male presents to the ED with sudden-onset, severe
tearing chest pain radiating to the back between the shoulder
blades. His blood pressure is 210/110 mmHg in the right arm and
160/90 mmHg in the left arm. A widened mediastinum is noted on
the chest radiograph. What is the primary medical management
goal upon admission?
A) Immediate administration of thrombolytic therapy.
B) Aggressive fluid resuscitation to maintain organ perfusion.
C) Rapid control of blood pressure and heart rate.
D) Immediate placement of an intra-aortic balloon pump (IABP).
Correct Answer: C
Detailed Rationale: Rationale: These clinical findings are hallmark
indicators of an acute aortic dissection (likely Stanford Type A or
B). The primary and immediate medical management goal is to
reduce the shear stress on the aortic wall by aggressively lowering
both blood pressure (target systolic BP 100-120 mmHg) and heart
rate (target HR < 60 bpm), typically using IV beta-blockers (e.g.,
esmolol or labetalol) and vasodilators (e.g., nitroprusside) if
needed. Thrombolytics would be fatal in aortic dissection.
Question 4
A 3-year-old toddler is brought to the ED by parents who report
sudden onset of coughing, wheezing, and decreased breath sounds
over the right lung field. The child swallowed a small toy 1 hour
, ago. Which diagnostic study is definitive for diagnosis and
treatment?
A) Inspiratory and expiratory chest radiographs
B) Flexible bronchoscopy under local anesthesia
C) Rigid bronchoscopy under general anesthesia
D) High-resolution computed tomography (HRCT) of the chest
Correct Answer: C
Detailed Rationale: Rationale: In pediatric foreign body aspiration,
rigid bronchoscopy performed under general anesthesia is the gold
standard and definitive method for both visualizing and safely
removing foreign bodies from the pediatric airway. Flexible
bronchoscopy is primarily diagnostic in adults but carries a higher
risk of airway obstruction or trauma in young children when
dealing with solid foreign bodies.
Question 5
An emergency nurse is caring for a patient experiencing acute
anaphylactic shock following a bee sting. After ensuring a patent
airway and administering intramuscular epinephrine, which
adjunct medication is appropriate to administer to block secondary
histamine release and late-phase allergic reactions?
A) Intravenous diphenhydramine and methylprednisolone
B) Sublingual nitroglycerin and aspirin
C) Intravenous regular insulin and dextrose
D) Inhaled hypertonic saline
Correct Answer: A
