Q: If a clinician identifies a regular, narrow-complex supraventricular tachycardia
(SVT) in a patient who is hemodynamically stable, what is the initial
recommended action? ✔️✔️ A: Vagal maneuvers. For a stable patient, non-invasive
techniques like the Valsalva maneuver or carotid sinus massage (if appropriate)
should be tried before moving to pharmacological interventions like Adenosine.
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?
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?
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?
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?
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?
“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?
35 to 45 mmHg
End-tidal carbon dioxide values in the range of 35 to 45 mmHg confirm adequacy
of ventilation.
