A pa ent's ECG reveals a narrow QRS complex with a regular rhythm, indica ng a narrow-
complex supraventricular tachyarrhythmia. The pa ent is hemodynamically stable. Which
interven on would be ini ated first?P
Vagal maneuvers
For a pa ent who is hemodynamically stable and experiencing a narrow-complex
supraventricular tachyarrhythmia, vagal maneuvers are a empted first. If ineffec ve, adenosine
is given.
A pa ent's capnogram reveals the following waveform. Which segment would the healthcare
provider interpret as reflec ng the beginning of exhala on?
A-B
The A–B segment is the respiratory baseline that represents the beginning of exhala on.
A pa ent experiencing an unstable bradyarrhythmia does not respond to atropine or
transcutaneous pacing. Which interven on would the healthcare provider use next?
Administra on of an epinephrine infusion.
Epinephrine or dopamine may be administered to pa ents with symptoma c bradycardia if
atropine and transcutaneous pacing are not effec ve.

A pa ent 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 magne c
resonance imaging is obtained by which me?
7:30 p.m.
In accordance with Na onal Ins tute of Neurological Disorders and Stroke guidelines, the stroke
team, emergency physician or other expert must conduct a neurologic assessment and obtain
, computed tomography or magne c resonance imaging within 20 minutes a,er the pa ent’s
arrival in the emergency department. That would be 7:30 p.m. for this pa ent.

A pa ent in the telemetry unit is stable. Cardiac monitoring indicates the pa ent 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 me?
Synchronized cardioversion
For a pa ent 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.
A resuscita on team is debriefing following a recent event. A pa ent experienced cardiac arrest,
and advanced cardiac life support was ini ated. The pa ent required the placement of an
advanced airway to maintain airway patency. Which statement indicates that the team
performed high-quality CPR?
“We delivered 1 ven la on 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 pa ent who is in cardiac arrest, compressions
and ven la ons are delivered con nuously with no interrup ons. One provider delivers 1
ven la on every 6 seconds, while the second provider performs compressions at a rate of 100 to
120 compressions per minute.
A healthcare provider ini ates ven la ons to ensure adequate breathing and oxygena on.
While ven la ons are being performed, capnography is established to evaluate the adequacy of
the ven la ons. The healthcare provider determines that ven la ons are adequate based on
which end- dal carbon dioxide (ETCO2) value?
35 to 45 mmHg
End- dal carbon dioxide values in the range of 35 to 45 mmHg confirm adequacy of ven la on.
