Question 1: which condition? Ventricular tachycardia Torsade de
pointes Asystole Ventricular fibrillation
Answer:

Ventricular tachycardia The cardiac monitor reveals ventricular tachycardia. In
pulseless ventricular tachycardia, the ventricular rate is usually greater than 180
beats per minute, and the QRS complexes are very wide. A patient with acute
renal failure experiences cardiac arrest. Just before the cardiac arrest, the
patient's ECG showed peaked T waves. What might be causing the patient's
cardiac arrest?



Question 2: Hypoxia Hypothermia Hyperkalemia Acidosis
Answer:

Hyperkalemia Suspect hyperkalemia in all patients with acute or chronic renal
failure who exhibit a wide-complex ventricular rhythm or tall, peaked T waves on
an ECG before cardiac arrest. A member of the resuscitation team is preparing to
defibrillate a patient in cardiac arrest using a biphasic defibrillator. The team
member would set the energy dose according to the manufacturer's
recommendations, which is usually:



Question 3: 75 to 100 joules 120 to 200 joules 300 joules 360 joules
Answer:

,120 to 200 joules When using a biphasic defibrillator, the energy dose should be
set at 120 to 200 joules. A member of the resuscitation team is preparing to
administer medications intravenously to a patient in cardiac arrest. The team
member should follow each peripherally administered drug dose with a normal
saline flush. How much would the team member give?



Question 4: 5 to 10 mL 10 to 20 mL 20 to 30 mL 30 to 40 mL
Answer:
10 to 20 mL When administering medications during a cardiac arrest, all
medications administrated through the IV or intraosseous infusion route should be
followed by a 10- to 20-mL normal saline flush. A 30-year-old patient has been
brought to the emergency department in cardiac arrest. The cardiac monitor
shows the following rhythm. Interpretation of this rhythm would suggest which of
the following as a possible precipitating factor?



Question 5: Hemorrhage Antibiotic use Electrocution Cardiac
tamponade
Answer:

Electrocution The rhythm is ventricular fibrillation. Precipitating causes of
ventricular fibrillation include electrocution, myocardial ischemia or infarction,
shock, stimulant overdose and ventricular tachycardia. Cardiac monitoring of a
patient in cardiac arrest reveals ventricular fibrillation. In addition to high-quality
CPR, what intervention should be a priority for the team?



Question 6: Perform a pulse check. Insert an advanced airway.
Defibrillation. Initiate capnography.
Answer:

,Defibrillation. The cardiac monitor is showing ventricular fibrillation, which is a
shockable rhythm. The team's priority should be to continue to provide
high-quality CPR and defibrillation. The resuscitation team suspects that
hyperkalemia is the cause of cardiac arrest in a patient brought to the emergency
department. Which finding on a 12-lead ECG would confirm this suspicion?



Question 7: Narrow-complex ventricular tachycardia Flat T waves,
prominent U waves and possibly prolonged QT intervals
ST-segment changes, T-wave inversion Wide-complex ventricular
rhythm and tall, peaked T waves
Answer:

Wide-complex ventricular rhythm and tall, peaked T waves In hyperkalemia, the
patient's 12-lead ECG will show a wide-complex ventricular rhythm and tall,
peaked T waves. A patient has experienced return of spontaneous circulation
(ROSC) after cardiac arrest. The healthcare team is conducting a secondary
assessment to determine the possible cause of the patient's cardiac arrest.
Before the arrest, the patient exhibited jugular venous distension, cyanosis,
apnea and hyperresonance on percussion. The patient was also difficult to
ventilate during the response. The team would most likely suspect which
condition as the cause?



Question 8: Hypothermia Cardiac tamponade Acidosis Tension
pneumothorax
Answer:

, Tension pneumothorax Prearrest signs of tension pneumothorax in the advanced
stage include jugular venous distension, cyanosis, apnea and hyperresonance on
percussion. Difficulty ventilating the patient may also be a sign of tension
pneumothorax. A patient in cardiac arrest experiences return of spontaneous
circulation. As part of post-cardiac arrest care, the patient is receiving mechanical
ventilation at an initial rate of 10 breaths/min and a fraction of inspired oxygen
(FiO2) of 0.30. Which finding(s) would indicate the need for change in the
ventilator settings to optimize the patient's ventilation and oxygenation?



Question 9: SaO2 96% SaO2 90% PaCO2 48 mmHg ETCO2 55
mmHg ETCO2 40 mmHg
Answer:

SaO2 90% PaCO2 48 mmHg ETCO2 55 mmHg Mechanical ventilation should be
started at a rate of 10 breaths per minute and adjusted as necessary to keep
carbon dioxide levels in physiologic range (PaCO2 between 35 and 45 mmHg or
monitored using ETCO2). The minimum fraction of inspired oxygen necessary to
maintain an SaO2 of 94% to 99% is used. After cardiac arrest and successful
resuscitation, the patient has a return of spontaneous circulation. The patient is
unable to follow verbal commands. Targeted temperature management is
initiated. Which method(s) would be appropriate for the resuscitation team to use?



Question 10: Administering cool-mist oxygen therapy Giving an
ice-cold IV fluid bolus Applying a cool compress to the patient's
forehead Applying cooling blankets to the patient's body Using an
endovascular catheter
Answer:
