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? - Precise Answer ✔✔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.
A patient's capnogram reveals the following waveform. Which segment
would the healthcare provider interpret as reflecting the beginning of
exhalation? - Precise Answer ✔✔A-B
The A-B segment is the respiratory baseline that represents the
beginning of exhalation.
A patient experiencing an unstable bradyarrhythmia does not respond to
atropine or transcutaneous pacing. Which intervention would the
healthcare provider use next? - Precise Answer ✔✔Administration of an
epinephrine infusion.
,Epinephrine or dopamine may be administered to patients with
symptomatic bradycardia if atropine and transcutaneous pacing are not
effective.
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? - Precise Answer ✔✔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.
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? - Precise Answer
✔✔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.
A resuscitation team is debriefing following a recent event. A patient
experienced 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? - Precise Answer ✔✔"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.
A healthcare provider initiates ventilations to ensure adequate breathing
and oxygenation. While ventilations are being performed, capnography
is established to evaluate the adequacy of the ventilations. The
healthcare provider determines that ventilations are adequate based on
which end-tidal carbon dioxide (ETCO2) value? - Precise Answer
✔✔35 to 45 mmHg
End-tidal carbon dioxide values in the range of 35 to 45 mmHg confirm
adequacy of ventilation.
An ECG strip of a patient in the emergency department reveals the
following rhythm. Which feature would the healthcare provider interpret
as indicating atrial fibrillation? - Precise Answer ✔✔Absence of discrete
P waves and presence of irregularly irregular QRS complexes.
