Session Final Exam Questions and
Answers
1. A patient's ECG reveals a narrow QRS complex with a regular
rhythm, indicating a narrow-complex supraventricular
tachyarrhythmia.
The patient is hemodynamically stable. Which intervention would be
initiated first?: Vagal maneuvers
For a patient who is hemodynamically stable and experiencing a narrow-complex supraventricular
tachyarrhythmia, vagal maneuvers are attempted first. If ineffective, adenosine is given.
2. A patient's capnogram reveals the following waveform. Which
ng of
segment would the healthcare provider interpret as reflecting
exhala-
the beginni
tion?: A-B
The A-B segment is the respiratory baseline that represents the beginning of exhalation.
3. A patient experiencing an unstable bradyarrhythmia does not
respond to atropine or transcutaneous pacing. Which intervention
,would the healthcare provider use next?: Administration of an epinephrine
infusion.
Epinephrine or dopamine may be administered to patients with symptomatic bradycardia if atropine and
transcuta- neous pacing are not effective.
4. A patient with a suspected stroke arrives at the emergency
department at 7:10 p.m. The stroke team ensures that a neurologic
assessment and brain computed tomography or magnetic
resonance imaging is obtained by which time?: 7:30 p.m.
In accordance with National Institute of Neurological Disorders and Stroke guidelines, the stroke team,
emergency physician or other expert must conduct a neurologic assessment and obtain computed
tomography or magnetic resonance imaging within 20 minutes after the patient's arrival in the
emergency department. That would be 7:30 p.m. for this patient.
5. A patient in the telemetry unit is stable. Cardiac monitoring
indicates the patient has ventricular tachycardia with a pulse.
Further assessment reveals that the corrected QT interval is
greater than 0.46 seconds. Which treatment would be appropriate at
this time?: Synchronized cardioversion
For a patient with ventricular tachycardia who is stable, has a pulse and has a corrected QT interval
greater than 0.46 seconds, synchronized cardioversion is the recommended treatment.
, 6. A resuscitation team is debriefing following a recent event. A
patient expe- rienced cardiac arrest, and advanced cardiac life
support was initiated. The patient required the placement of an
advanced airway to maintain airway patency. Which statement
indicates that the team performed high-quality CPR?: "We delivered 1
ventilation every 6 seconds and chest compressions at a rate of 100 to 120 compressions per
minute."
When an advanced airway has been placed in a patient who is in cardiac arrest, compressions and
ventilations are delivered continuously with no interruptions. One provider delivers 1 ventilation every 6
seconds, while the second provider performs compressions at a rate of 100 to 120 compressions per
minute.
7. A healthcare provider initiates ventilations to ensure adequate
breathing and oxygenation. While ventilations are being performed,
capnography is estab- lished to evaluate the adequacy of the
ventilations. The healthcare provider determines that ventilations are
adequate based on which end-tidal carbon dioxide (ETCO2) value?: 35
to 45 mmHg
End-tidal carbon dioxide values in the range of 35 to 45 mmHg confirm adequacy of ventilation.

omplexes
