Final answer:
The recommended option is to administer Methylene Blue to treat the elevated methemoglobin level in the patient. It is important to closely monitor the patient's condition and consult with a healthcare professional for further guidance.
Step-by-step explanation:
The methemoglobin level of 9% indicates that the patient has an elevated level of methemoglobin.
Methemoglobin is a form of hemoglobin that is unable to bind oxygen effectively, resulting in reduced oxygen delivery to the tissues.
To treat methemoglobinemia, the recommended option is to administer Methylene Blue.
Methylene Blue acts as a reducing agent and converts methemoglobin back to its normal functional form, hemoglobin. This will help restore oxygen-carrying capacity and improve oxygen delivery to the tissues.
