NCLEX Question of the Day – Wednesday, March 11, 2026

Today’s question focuses on Pharmacology, specifically safe insulin administration and early recognition of hypoglycemia. This matters in real nursing because insulin errors can harm a patient quickly. A nurse must connect the medication, the patient’s current status, and the timing of meals. Good pharmacology practice is not just knowing a drug name. It is knowing when to give it, when to hold it, and what to monitor next.

Clinical Scenario

A 67-year-old man is admitted to a medical-surgical unit with community-acquired pneumonia and type 2 diabetes mellitus. His home medications include metformin and bedtime insulin glargine. During this admission, he is prescribed a basal-bolus insulin regimen with insulin glargine once daily and insulin lispro before meals. At 1130, the nurse checks his blood glucose before lunch and gets a reading of 72 mg/dL. The patient is awake, slightly sweaty, and says, “I feel shaky and hungry.” His lunch tray has not arrived yet because the kitchen is delayed. The MAR shows insulin lispro 6 units subcutaneously due now with a correction scale if needed.

The Question

What is the nurse’s priority action?

Answer Choices

1. Administer the scheduled insulin lispro and ask dietary services to send the lunch tray as soon as possible.
2. Hold the insulin lispro, give 15 g of rapid-acting carbohydrate, and recheck the blood glucose in 15 minutes.
3. Document the finding as an expected pre-meal value and reassess the patient after lunch.
4. Notify the provider that the patient’s insulin regimen should be discontinued because of hypoglycemia.

Correct Answer

B. Hold the insulin lispro, give 15 g of rapid-acting carbohydrate, and recheck the blood glucose in 15 minutes.

Detailed Rationale

This patient is showing early symptomatic hypoglycemia. The blood glucose is 72 mg/dL, which is low enough to matter because the patient also has symptoms: shakiness, sweating, and hunger. Symptoms change the situation. Even a borderline number becomes more urgent when the patient is symptomatic.

The nurse’s first job is to prevent the glucose from dropping further. Insulin lispro is rapid-acting. Giving it now would push the blood sugar lower, especially since the meal is delayed. That creates immediate risk for worsening hypoglycemia, confusion, seizures, or loss of consciousness.

The safest action is to hold the lispro and treat the low blood sugar with 15 g of rapid-acting carbohydrate. Examples include 4 oz of juice or glucose tablets according to facility policy. The reason for rapid-acting carbohydrate is speed. The patient is awake and can swallow, so oral treatment is appropriate.

After treatment, the nurse should recheck the blood glucose in 15 minutes. This matters because treatment is not complete until you know it worked. If the glucose is still low, the nurse repeats treatment per protocol. Once the blood glucose has improved and the meal is available, the nurse can reassess whether prandial insulin should be given, following the order and facility policy.

The nurse should also assess a few key things right away:

• Level of consciousness and ability to swallow safely.
• Timing of the last meal and any recent poor intake.
• Other symptoms such as confusion, weakness, blurred vision, or palpitations.
• Whether any other glucose-lowering medications were recently given.

Then the nurse should monitor:

• Repeat blood glucose after treatment.
• Resolution or worsening of symptoms.
• Arrival of the meal tray and actual food intake.
• Need to communicate with the provider if hypoglycemia is recurrent or the patient is unable to maintain a safe glucose level.

This question tests a core NCLEX habit: treat the patient’s current problem before carrying out a routine medication task. The scheduled insulin matters, but the symptomatic low glucose matters more.

Why the Other Options Are Wrong

A. Administer the scheduled insulin lispro and ask dietary services to send the lunch tray as soon as possible.

This is unsafe. Lispro works quickly, often within minutes. Giving it when the patient is already symptomatic and the tray is delayed could worsen hypoglycemia before food arrives. Nursing judgment comes before routine timing.

C. Document the finding as an expected pre-meal value and reassess the patient after lunch.

This ignores both the symptoms and the delayed tray. A pre-meal glucose of 72 mg/dL is not “fine” in a shaky, sweaty patient. The nurse must intervene now, not later. Reassessment without treatment delays care.

D. Notify the provider that the patient’s insulin regimen should be discontinued because of hypoglycemia.

This jumps too far ahead. One low reading with a delayed meal does not mean the entire insulin regimen should be stopped. The immediate priority is treatment of hypoglycemia. The provider may need to be notified later if the patient has repeated lows, poor intake, or changing insulin needs, but that is not the first action.

Key Takeaways

• Symptoms matter as much as the number. A mildly low glucose can still be urgent if the patient is symptomatic.
• Do not give rapid-acting insulin when the patient is hypoglycemic or when a meal is not ready.
• If the patient is awake and can swallow, give 15 g of rapid-acting carbohydrate and recheck in 15 minutes.
• Always connect insulin timing to actual food availability, not just the clock.

What you’d do on shift:

• See the low sugar and symptoms.
• Hold the lispro.
• Give a fast carbohydrate per protocol.
• Recheck in 15 minutes.
• Make sure the meal arrives and the patient eats.
• Document the event, response, and any follow-up communication.

Quick Practice Extension

1. If this patient were drowsy and unable to swallow safely, what treatment route would you expect the nurse to use instead of oral carbohydrate?

2. If the blood glucose rises after treatment but the patient then eats only a few bites of lunch, what should the nurse monitor closely over the next hour?

Questions like this are really about timing, safety, and noticing small warning signs before they become emergencies. In practice, the best nurses do not just give insulin because it is scheduled. They stop, look at the patient, and ask one critical question: Is it safe to give this right now?
