Final answer:
Before assisting with a metered dose inhaler, confirm the patient's identity, ensure the medication is correct and the inhaler is functioning, and check for known allergies.
Step-by-step explanation:
Before assisting a patient with a metered dose inhaler, you must ensure several important factors. First, verify the patient's identity and make certain that you are administering the medication to the correct individual. Second, confirm that the medication is appropriate for the patient; the inhaler must contain medicine intended for their specific condition, such as albuterol for asthma. Additionally, ensure that the inhaler is functioning properly without any leaks which could prevent the medication from being delivered effectively. Lastly, check if the patient has any known allergies, particularly to the medication, to avoid any adverse reactions. While the availability of more medication at the hospital may be important, it is not the immediate concern when preparing to administer a dose from a metered dose inhaler.
