A 45-year-old client with type 2 diabetes mellitus has been NPO since midnight for a scheduled cholecystectomy. The client appears highly anxious about the procedure, and the 6:00 AM blood glucose reading is 180 mg/dL. Recognizing this value in the preoperative setting, what is the nurse's best action?

Elevated preoperative blood glucose levels significantly increase surgical risks and complications.

Core Nursing Explanation Key Concept Analysis: This question assesses the critical nursing action for hyperglycemia in a preoperative patient who is NPO (Nothing by mouth). The core principle is that uncontrolled hyperglycemia impairs wound healing and increases the risk of surgical site infections (SSI). A blood glucose of 180 mg/dL is significantly elevated for a fasting patient, especially one who is anxious (stress can raise blood glucose). The nurse's role is to recognize this as a potential safety risk that requires intervention before proceeding with surgery.

Answer Rationale: Key Point! The best action is to notify the surgeon immediately. The surgeon needs to be informed to decide on the plan of care. They may order a sliding scale insulin dose, delay the surgery, or provide other specific instructions. This action prioritizes patient safety by addressing a modifiable risk factor (hyperglycemia) before an invasive procedure.

Distractor Analysis: Watch out for confusion! Option ① is incorrect because administering the regular morning insulin dose to an NPO patient can lead to dangerous hypoglycemia during surgery. Preoperative insulin regimens are often adjusted (e.g., holding long-acting insulin or giving a reduced dose with IV dextrose).
Option ③ is incorrect because simply documenting and proceeding ignores a significant abnormal finding that directly impacts surgical outcomes. Passive documentation is not an appropriate intervention for an actionable risk.
Option ④ is incorrect and dangerous. The client is NPO for surgery; encouraging clear fluids violates the preoperative order and poses an aspiration risk during anesthesia. Furthermore, clear fluids (unless specified as sugar-free) could raise blood glucose further.

Related Concepts: Perioperative management of diabetes focuses on maintaining blood glucose within a target range (often 80-180 mg/dL) to promote healing and prevent complications. Stress-induced hyperglycemia is common. The nursing process requires assessment (checking glucose), identification of a problem (elevated level), and implementation of an appropriate intervention (communication with the provider).

Nursing Clinical Practice Guide Clinical Scenario: You are the preoperative nurse. Mr. Jones, a 45-year-old with Type 2 DM, is scheduled for a laparoscopic cholecystectomy at 8:00 AM. He has been NPO since midnight but tells you he's "really nervous." You obtain his 6:00 AM fingerstick blood glucose as per protocol, and it reads 180 mg/dL.

Nursing Intervention Strategy: 1. Assessment: Immediately re-check the blood glucose with a new strip and proper technique to rule out error. Assess the patient for other signs of hyperglycemia (e.g., thirst, frequent urination) or dehydration. 2. Communication & Planning: Notify the surgeon and/or anesthesia provider immediately via phone or in person. Report: "Patient's preoperative blood glucose is 180 mg/dL. He is NPO and anxious. Requesting orders for glycemic management prior to surgery." 3. Implementation: Follow the new orders precisely. This may involve administering a one-time dose of rapid-acting insulin as ordered. Continue to monitor blood glucose per protocol. Provide emotional support and clear explanations to alleviate the patient's anxiety, which can help lower stress-induced hyperglycemia. 4. Patient Safety and Precautions: Never give anything by mouth. Confirm NPO status. Be vigilant for signs of both hyperglycemia and hypoglycemia after any insulin administration. Ensure the operating room team is aware of the blood glucose level and any interventions performed.

Nursing Procedure & Medication Flow When administering insulin preoperatively: - Verify the order carefully (type of insulin, dose, route). - Perform independent double-check of the insulin dose with another nurse. - Administer subcutaneously as ordered. - Monitor blood glucose frequently (e.g., every 30-60 minutes) as per unit protocol or physician order. - Have a source of fast-acting glucose (e.g., D50W IV) readily available in case of hypoglycemia.

A Word from Your Senior Nurse "In the fast-paced preoperative area, it's easy to just 'check the box' and send the patient to the OR. But you are the last safety checkpoint. A blood glucose of 180 mg/dL isn't just a number—it's a flashing red light that says 'infection risk ahead.' Your critical thinking and willingness to speak up can directly prevent a postoperative complication for your patient. On the NCLEX, they test this 'notify the provider' action constantly because in real life, it's what saves lives and prevents errors. Always connect the lab value to the patient's immediate situation!"
