While dining at a restaurant, a person begins to choke. Which of the following actions should the nurse take?
- A. Instruct the person to call 911.
- B. Ask the person if he/she can speak.
- C. Use the jaw-thrust maneuver.
- D. Perform abdominal thrusts.
Correct Answer: B
Rationale: The correct answer is B because asking the person if he/she can speak helps to determine if the airway is partially or completely obstructed. If the person can speak, it indicates that the airway is not completely blocked, and coughing may help dislodge the object. If the person cannot speak, it suggests a complete blockage, and immediate intervention is needed. In contrast, A is incorrect as the nurse should take action rather than instructing the person to call 911. C is incorrect because the jaw-thrust maneuver is used for assisting with breathing, not for choking. D is incorrect because abdominal thrusts are only performed when the person is unable to speak, indicating a complete airway obstruction.

- A. Perform the chin lift or jaw thrust maneuver
- B. Establish unresponsiveness
- C. Initiate cardiopulmonary resuscitation (CPR)
- D. Call for help and activate the code team
Correct Answer: B
Rationale: Establishing unresponsiveness is the first step in assessing the patient's condition.
