COMPLETE QUESTIONS AND CORRECT VERIFIED
ANSWERS WITH RATIONALES (A NEW UPDATED
VERSION) |GUARANTEED PASS.
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?
Answer- Synchronized cardioversion
Rationale: 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?
,Answer- “We delivered 1 ventilation every 6 seconds and chest
compressions at a rate of 100 to 120 compressions per minute.”
Rationale: 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, scenography
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?
Answer- 35 to 45 mmHg
Rationale: 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?
Answer- Absence of discrete P waves and presence of irregularly
irregular QRS complexes.
, Rationale: The two key features of atrial fibrillation on ECG are the
absence of discrete P waves and the presence of irregularly irregular
QRS complexes.
A patient in cardiac arrest experiences return of spontaneous circulation.
As part of post-cardiac arrest care, the patient is receiving mechanical
ventilation. Which finding(s) would indicate the need for change in the
ventilator settings to optimize the patient's ventilation and oxygenation?
1. ETCO2 50 mmHg
2. PaCO2 35 mmHg
3. SaO2 92%
Rationale: Mechanical ventilation should be started at a rate of 10 to 12
breaths per minute and adjusted as necessary to keep ETCO2 levels in
the range of 35 to 40 mmHg and PaCO2 levels in the range of 40 to 45
mmHg. The minimum fraction of inspired oxygen necessary to maintain
an SaO2 of at least 94% is used.
The following capnogram is from a patient experiencing respiratory
distress. At which point in the waveform would the patient's ETCO2
level be measured?
