The nurse obtains a fingerstick blood glucose level using a bedside glucose meter from a client with a prescribed sliding scale insulin protocol. The meter indicates 56 mg/dL (3.12 mmol/L). At this time, which intervention should the nurse implement first?
Reference Range: Glucose 74 to 106 mg/dL (4.1 to 5.9 mmol/L)

Choice A reason: Preparing the prescribed dose of rapid-acting insulin from the sliding scale instructions is not appropriate when the client's blood glucose level is low (56 mg/dL). Administering insulin at this point could further lower the blood glucose level, potentially leading to severe hypoglycemia. The priority is to raise the client's blood glucose level to a safe range.

Choice B reason: Giving the client six ounces of non-diet carbonated soda and instructing the client to drink it entirely is the correct first intervention. The client’s blood glucose level is significantly below the normal reference range (hypoglycemia). Administering a fast-acting carbohydrate, such as non-diet soda, helps to quickly increase the blood glucose level to a safer range. This intervention addresses the immediate need to correct the hypoglycemia and prevent potential complications such as confusion, seizures, or loss of consciousness.

Choice C reason: Collecting a blood specimen by venipuncture to send to the laboratory for serum glucose analysis is not the first intervention to implement. While laboratory confirmation of blood glucose levels can be important, the immediate priority is to treat the hypoglycemia. Delaying treatment to collect a laboratory specimen could result in worsening of the client's condition. Immediate administration of a fast-acting carbohydrate should be prioritized.

Choice D reason: Documenting the glucose reading in the electronic medical record (EMR) is important but not the first priority. While accurate documentation is necessary for ongoing care, the immediate intervention should focus on treating the hypoglycemia. Once the client's blood glucose level has been stabilized, the nurse can then document the reading and subsequent interventions in the EMR.
