A nurse is caring for a diabetic client with a preoperative blood glucose of 200 mg/dL scheduled for major abdominal surgery in the morning. Which nursing action should be the highest priority during the preoperative period?

Highest priority is monitoring blood glucose every 2-4 hours to maintain euglycemia, as hyperglycemia increases surgical risks like infection and poor wound healing. Other actions are important but secondary: NPO status is standard, insulin may need adjustment, and lab verification does not address immediate glucose control.

Core Nursing Explanation This question tests the nurse's ability to prioritize care for a diabetic patient in the preoperative period. The core concept is managing perioperative hyperglycemia, a significant risk factor for surgical complications. Key Concept Analysis The patient has Diabetes Mellitus (DM) and an elevated preoperative blood glucose of 200 mg/dL. This indicates hyperglycemia, which is a critical concern before surgery. Uncontrolled hyperglycemia impairs immune function, increases the risk of surgical site infections (SSI), delays wound healing, and can lead to metabolic disturbances like diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemic state (HHS). The primary goal is to achieve and maintain euglycemia (normal blood glucose range) to minimize these risks. Answer Rationale Key Point! The highest priority action is Monitor blood glucose levels every 2-4 hours and maintain euglycemia. This is a direct, ongoing, and active intervention to manage the patient's most immediate and modifiable risk factor. Frequent monitoring allows for timely interventions (e.g., sliding scale insulin) to correct hyperglycemia before it causes harm. This action embodies the nursing principles of assessment and intervention to ensure patient safety. Distractor Analysis Watch out for confusion! While the other actions are part of standard preoperative care, they are not the highest priority for this specific patient scenario.
② Ensure NPO status: This is a standard preoperative order to prevent aspiration. However, it is a routine protocol and does not specifically address the identified problem of hyperglycemia. For a diabetic patient, prolonged NPO status itself can create a risk for hypoglycemia, which also needs monitoring.
③ Administer regular morning insulin: This could be dangerous. If the patient is NPO and not eating, administering their usual dose of intermediate or long-acting insulin could cause severe hypoglycemia during surgery. Insulin regimens are typically adjusted on the day of surgery (e.g., holding or giving a reduced dose), based on specific physician orders and blood glucose levels.
④ Verify lab results: This is an important safety check, but it is an administrative/verification task. It does not constitute an active intervention to correct the existing hyperglycemia. The abnormal glucose level is already known. Related Concepts Perioperative diabetes management often involves a variable rate intravenous insulin infusion (VRIII) or "insulin drip" for major surgeries to provide tight glycemic control. The target blood glucose range during the perioperative period is typically 140-180 mg/dL. Understanding the difference between managing hyperglycemia risk versus hypoglycemia risk is crucial. Concept Summary

Concept	Explanation	Nursing Implication
Perioperative Hyperglycemia	Elevated blood glucose around surgery time.	Increases infection risk, impairs healing. Priority is frequent monitoring and correction.
Euglycemia	Normal blood glucose level (70-110 mg/dL fasting, target 140-180 mg/dL perioperatively).	The therapeutic goal for diabetic surgical patients.
NPO & Insulin Risk	Withholding food without adjusting insulin can cause hypoglycemia.	Never administer routine insulin to an NPO patient without specific orders. Hold or reduce dose per protocol.

Side-by-Side Comparison!

Preop Priority for Diabetic Patient	Preop Priority for General Patient
Key Point! Glycemic Control: Monitor and manage blood glucose.	NPO Compliance & Aspiration Prevention: Ensure patient has had nothing by mouth.
Adjust insulin/medications per protocol.	Verify consent and preoperative checklist.
Assess for signs of hyper/hypoglycemia.	Assess baseline vital signs and anxiety level.

Anatomy, Physiology & Pharmacology Points Pathophysiology: Hyperglycemia creates an osmotic diuresis, leads to dehydration, and impairs neutrophil function (white blood cells), reducing the body's ability to fight infection at the surgical site.
Pharmacology: Know the onset, peak, and duration of the patient's insulin type (e.g., rapid-acting, long-acting). Sliding scale insulin (SSI) is commonly used for correction doses based on frequent blood glucose checks. Memory Tips ABCs + Glucose: In many priority questions, think Airway, Breathing, Circulation. For a diabetic patient, add "Glucose" to your immediate assessment priorities, especially in the perioperative setting.
Acronym: Diabetic Patient Pre-Op = Don't Panic, Prick (check glucose)! High-Frequency NCLEX Topics NCLEX loves to test priority-setting for patients with chronic illnesses undergoing procedures. Diabetes management in the context of surgery, labor, or acute illness is a classic scenario. Remember: Address the problem that poses the greatest immediate threat to the patient's safety and surgical outcome. Here, uncontrolled glucose is that threat. Watch Out for Question Variations! * Shift from Assessment to Intervention: "The nurse notes a preoperative blood glucose of 280 mg/dL. What action should the nurse take first?" (Answer: Notify the surgeon/anesthesiologist and initiate glucose monitoring protocol). * Postoperative Focus: "A diabetic patient is 4 hours post-op. Which finding requires immediate intervention?" (Options might include hypoglycemia symptoms vs. mild incisional pain). * Medication Adjustment: "The patient takes 20 units of NPH insulin every morning. They are NPO for surgery at 8 AM. What should the nurse do?" (Answer: Hold the morning NPH insulin and monitor blood glucose, as per typical protocol).

Nursing Clinical Practice Guide Clinical Scenario: You are the pre-op nurse for Mr. Jones, a 58-year-old with Type 2 DM, scheduled for a colectomy. His 6 AM fingerstick blood glucose is 210 mg/dL. He has been NPO since midnight and is anxious. Nursing Intervention Strategy 1. Assessment: Immediately document the elevated glucose. Assess for signs of hyperglycemia (polyuria, polydipsia, blurred vision) or dehydration (dry mucous membranes, poor skin turgor). Check his most recent HbA1c if available. 2. Planning & Implementation: Initiate frequent glucose monitoring (every 2 hours). Follow the institution's preoperative diabetes protocol, which likely involves notifying the surgeon/anesthesiologist. They may order a variable rate intravenous insulin infusion (VRIII) to start in pre-op or hold oral medications/adjust subcutaneous insulin. 3. Patient Education: Explain to Mr. Jones why his blood sugar is being checked so often and that controlling it is key to preventing infection after surgery. 4. Evaluation: The goal is to have his blood glucose within the target range (140-180 mg/dL) before entering the operating room. Patient Safety and Precautions * Key Point! Hypoglycemia is a greater immediate danger than hyperglycemia in an NPO/sedated patient. Always have a source of rapid-acting glucose (e.g., D50W IV, oral glucose gel) readily available. * Never assume an insulin order is correct for an NPO patient. Always verify with the protocol or prescriber. * Communicate the patient's glucose trends and insulin requirements clearly during handoff to the OR and PACU (Post-Anesthesia Care Unit) nurses. Nursing Procedure & Medication Flow Blood Glucose Monitoring (Pre-Op): 1. Perform hand hygiene and don gloves. 2. Use a lancet to obtain a capillary blood sample from the side of the fingertip. 3. Apply blood to the test strip in the glucometer. 4. Document the result, time, and any related interventions (e.g., "BG 210 mg/dL, surgeon notified, order received for 2-unit correction dose of rapid-acting insulin").
Insulin Administration (Pre-Op - if ordered): 1. Double-check the order against the protocol for NPO patients. 2. Use only rapid-acting insulin (e.g., aspart, lispro) for correction doses, as its short duration minimizes post-operative hypoglycemia risk. 3. Administer subcutaneously, and ensure the patient has a meal tray ordered for post-op arrival to the PACU to prevent hypoglycemia. A Word from Your Senior Nurse "In the fast-paced pre-op area, it's easy to get caught up in checklists and consent forms. But for our diabetic patients, that glucometer is one of our most important tools. Catching and correcting that high blood sugar before they roll back to the OR is a direct action you can take to improve their surgical outcome. It's not just a number on a screen; it's a predictor of their risk for infection and healing. On the NCLEX and at the bedside, always ask yourself: 'What is the biggest, most immediate threat to this specific patient's safety right now?' For Mr. Jones with a BG of 200, it's not that he signed the consent form—it's the unseen bacteria that his elevated glucose is inviting to his future incision site. You are his first line of defense."
