What should you do first if a patient has an acrylic or gold crown lodged in their throat?

In the situation where a patient has an acrylic or gold crown lodged in their throat, the immediate priority is to remove the obstruction to restore the airway. Performing the Heimlich maneuver is the correct first step because it is specifically designed to expel objects blocking the airway. This maneuver applies pressure to the abdomen, creating enough force to help dislodge the obstruction.

Other options may not be appropriate as an initial response. For example, calling emergency services is important but may delay the critical action needed to clear the airway. Administering CPR is necessary only if the patient becomes unresponsive and is not breathing, indicating a more severe situation that follows basic airway management. Giving the patient water could potentially worsen the situation by further lodging the obstruction or increasing the risk of choking.

Therefore, performing the Heimlich maneuver is the most appropriate and immediate action to take, addressing the critical nature of the airway obstruction.
