CPR Post-Resuscitation Care & Recovery 2 — Questions and Answers
Question 1: After return of spontaneous circulation (ROSC), what oxygen saturation range should be targeted to avoid hyperoxia?
- 94-99% (Correct answer)
- 100% at all times
- 85-90%
- 70-80%
Correct answer: 94-99%
Titrate oxygen to keep SpO2 between 94-99% to prevent both hypoxia and harmful hyperoxia.
Question 2: Targeted temperature management after cardiac arrest typically maintains core temperature in which range?
- 32-36 C (Correct answer)
- 38-40 C
- 28-30 C
- 25-27 C
Correct answer: 32-36 C
Current guidelines recommend a constant target between 32 C and 36 C for at least 24 hours.
Question 3: Which finding immediately after ROSC most strongly indicates the need to identify and treat a reversible cause?
- Persistent hypotension (Correct answer)
- Normal blood pressure
- Spontaneous eye opening
- Strong radial pulse
Correct answer: Persistent hypotension
Persistent hypotension signals ongoing instability and prompts a search for reversible causes like hypovolemia.
Question 4: What is the recommended approach to ventilation rate in an intubated patient after ROSC?
- 10 breaths per minute (Correct answer)
- 30 breaths per minute
- 4 breaths per minute
- As fast as possible
Correct answer: 10 breaths per minute
Provide about 10 breaths per minute and avoid hyperventilation, which lowers cardiac output.
Question 5: A patient regains a pulse but remains unresponsive. What is the priority next step?
- Begin post-cardiac arrest care and monitoring (Correct answer)
- Discontinue all monitoring
- Send the patient home
- Stop oxygen support
Correct answer: Begin post-cardiac arrest care and monitoring
An unresponsive patient with ROSC needs structured post-arrest care including airway, breathing, and circulation support.
Question 6: Which blood pressure target is generally recommended after ROSC?
- Systolic above 90 mmHg / MAP above 65 mmHg (Correct answer)
- Systolic below 70 mmHg
- MAP below 40 mmHg
- Any pressure is acceptable
Correct answer: Systolic above 90 mmHg / MAP above 65 mmHg
Maintaining systolic above 90 mmHg or mean arterial pressure above 65 mmHg supports organ perfusion.
Question 7: Why should a 12-lead ECG be obtained quickly after ROSC?
- To detect a STEMI needing emergency catheterization (Correct answer)
- To measure body temperature
- To assess kidney function
- To check oxygen saturation
Correct answer: To detect a STEMI needing emergency catheterization
A 12-lead ECG identifies STEMI, which may require urgent coronary angiography and intervention.
