A patient with possible carbon monoxide exposure has a reassuring pulse-oximetry reading but appears unwell. What is the best interpretation of the reading?
- A
A reassuring reading rules out respiratory distress
- B
Repeat the reading until it is high, then stop assessing
- C
Interpret the reading with the whole assessment because carbon monoxide exposure can make it misleading
- D
Withhold further assessment unless the reading falls

Select all statements consistent with the 2025 AHA guidance for foreign-body airway obstruction.
- A
For adults and children with severe obstruction, use cycles of five back blows and five abdominal thrusts
- B
For infants with severe obstruction, use five back blows alternating with five abdominal thrusts
- C
For infants with severe obstruction, use five back blows alternating with five chest thrusts
- D
If the patient becomes unresponsive, begin CPR and remove an object only if it is visible
- E
Perform a blind finger sweep if the object cannot be seen

You are using a bag-valve-mask, but the patient’s chest does not rise. Which response best follows the recommended troubleshooting steps?
- A
Increase the force and speed of breaths immediately
- B
Reposition the airway, improve the mask seal, and check for obstruction
- C
Stop reassessing and switch to supplemental oxygen alone
- D
Perform a blind finger sweep

A patient looks breathless, but the pulse oximeter gives a reassuring reading while the patient's perfusion is poor. What is the best interpretation?
- A
Treat the reading as definitive if it appears reassuring.
- B
Interpret it alongside the patient's effort, mental status, and overall appearance.
- C
Use it instead of observing chest rise and breathing effort.
- D
Assume it is accurate even when perfusion is poor.

A patient with possible spinal injury has an obstructed airway. Which initial approach best balances airway care with minimizing movement?
- A
Use a head-tilt/chin-lift and avoid reassessment.
- B
Perform a blind finger sweep before attempting to open the airway.
- C
Use a jaw-thrust while minimizing movement; if it does not open the airway, prioritize airway and ventilation needs.
- D
Delay airway care until a detailed history is complete.

- B
Alternate five back blows with five abdominal thrusts.
- C
Encourage coughing only, regardless of whether the obstruction is severe.
