CPR Post-Resuscitation Care & Recovery 3 — Questions and Answers
Question 1: What is the primary goal of targeted temperature management after cardiac arrest?
- Protect the brain and improve neurological outcome (Correct answer)
- Increase heart rate
- Raise blood glucose
- Speed up breathing
Correct answer: Protect the brain and improve neurological outcome
Controlled temperature reduces secondary brain injury and improves the chance of good neurological recovery.
Question 2: Which laboratory abnormality is commonly monitored and corrected during post-resuscitation care?
- Blood glucose (Correct answer)
- Hair color
- Bone density
- Eye pressure
Correct answer: Blood glucose
Both high and low blood glucose worsen outcomes, so glucose is monitored and kept in a moderate range.
Question 3: During rewarming after targeted temperature management, what should be avoided?
- Rapid rewarming and rebound fever (Correct answer)
- Slow controlled rewarming
- Continuous temperature monitoring
- Gradual temperature increase
Correct answer: Rapid rewarming and rebound fever
Rewarming should be slow and fever afterward must be prevented because it harms the brain.
Question 4: Why is hyperventilation harmful in the post-arrest period?
- It reduces cerebral blood flow and cardiac output (Correct answer)
- It improves brain perfusion
- It raises blood pressure safely
- It increases carbon dioxide
Correct answer: It reduces cerebral blood flow and cardiac output
Excessive ventilation lowers CO2, constricting cerebral vessels and reducing both brain and heart output.
Question 5: What does the term post-cardiac arrest syndrome describe?
- Brain injury, myocardial dysfunction, and systemic ischemia-reperfusion (Correct answer)
- A type of heart valve disease
- A chronic lung infection
- A normal recovery process
Correct answer: Brain injury, myocardial dysfunction, and systemic ischemia-reperfusion
Post-cardiac arrest syndrome combines brain injury, heart dysfunction, and whole-body reperfusion injury.
Question 6: Which intervention helps protect kidney function after cardiac arrest?
- Maintaining adequate blood pressure and perfusion (Correct answer)
- Withholding all fluids
- Inducing severe hypotension
- Stopping monitoring
Correct answer: Maintaining adequate blood pressure and perfusion
Adequate perfusion pressure and fluid balance protect the kidneys from ischemic injury.
Question 7: When should coronary angiography be strongly considered after ROSC?
- When the ECG shows ST-elevation MI (Correct answer)
- When the patient is fully awake and stable
- Only after several days
- Never after cardiac arrest
Correct answer: When the ECG shows ST-elevation MI
STEMI on the post-ROSC ECG warrants emergency angiography to open a blocked coronary artery.
