A patient experiences a gasoline tank fire when riding a motorcycle and is admitted to the emergency department (ED. with partial-thickness burns on the anterior surfaces of both lower extremities. Which percentage of body surface area should the nurse document in the electronic medical record (EMR)?

Choice A: Taking metformin with the morning and evening meal is a correct statement for the nurse to include, as this can improve the absorption and effectiveness of metformin and reduce the risk of gastrointestinal side effects. Therefore, this is a correct choice.

Choice B: Using sliding scale insulin for frequent blood glucose elevations is not a correct statement for the nurse to include, as this is not recommended for clients with type 2 DM who are taking metformin. This can cause hypoglycemia and complicate the management of blood glucose levels. This is an incorrect choice.

Choice C: Recognizing signs and symptoms of hypoglycemia is a correct statement for the nurse to include, as this can help the client identify and treat low blood glucose levels, which can occur with metformin use or other factors such as exercise, fasting, or alcohol intake. Therefore, this is another correct choice.

Choice D: Reporting persistent polyuria to the health care provider is a correct statement for the nurse to include, as this can indicate poor glycemic control or a complication of DM such as diabetic ketoacidosis or nephropathy. Therefore, this is another correct choice.

Choice E: Taking an additional dose for signs of hyperglycemia is not a correct statement for the nurse to include, as this can cause overdose or toxicity of metformin, which can lead to lactic acidosis and renal failure. This is another incorrect choice.

Choice A: Conversion of the client's PPD test from negative to positive is not the most important information for the nurse to note, as this is an expected finding for a client who has been exposed to tuberculosis and does not affect the administration of isoniazid. This is a distractor choice.

Choice B: History of intravenous drug abuse is not the most important information for the nurse to note, as this is not directly related to the use of isoniazid and does not contraindicate its administration. This is another distractor choice.

Choice C: Current diagnosis of hepatitis B is the most important information for the nurse to note, as this can increase the risk of hepatotoxicity and liver damage from isoniazid, which requires close monitoring and possible dose adjustment. Therefore, this is the correct choice.

Choice D: Length of time of the exposure to tuberculosis is not the most important information for the nurse to note, as this does not influence the dosage or frequency of isoniazid and does not indicate any complication or adverse reaction. This is another distractor choice.
