NCLEX Question of the Day – Thursday, July 02, 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 fast. A nurse must connect the medication, the timing, the meal plan, and the patient’s symptoms in one quick clinical judgment.

Clinical Scenario

A 67-year-old man is admitted to a medical-surgical unit with community-acquired pneumonia and type 2 diabetes mellitus. He takes insulin at home. At 0730, the nurse checks his blood glucose and gets a result of 238 mg/dL. The provider’s orders include insulin lispro before meals based on a sliding scale and insulin glargine 18 units subcutaneously every evening. The nurse gives the prescribed dose of insulin lispro at 0745.

At 0800, the dietary department calls to report that breakfast trays will be delayed by at least 45 minutes because of a kitchen equipment problem. At 0810, the patient tells the nurse, “I feel shaky and a little dizzy.” He is pale and mildly diaphoretic. A repeat bedside blood glucose is 62 mg/dL. He is awake, follows commands, and can swallow without difficulty.

The Question

What is the nurse’s priority action?

Answer Choices

1. Administer 15 g of rapid-acting carbohydrate and recheck the blood glucose in 15 minutes.
2. Hold the next scheduled dose of insulin glargine and document the episode.
3. Notify the provider immediately before taking any action because the blood glucose dropped after insulin administration.
4. Give 1 mg glucagon by intramuscular injection and place the patient in side-lying position.

Correct Answer

A. Administer 15 g of rapid-acting carbohydrate and recheck the blood glucose in 15 minutes.

Detailed Rationale

This patient has symptomatic hypoglycemia. The key clues are the recent rapid-acting insulin dose, delayed meal, shakiness, dizziness, diaphoresis, pallor, and blood glucose of 62 mg/dL. The priority is to treat the low blood sugar right away because the brain depends on glucose. If the nurse waits, the patient can quickly worsen from mild symptoms to confusion, seizure, or loss of consciousness.

The patient is awake and can swallow safely. That makes oral treatment the best first step. A standard nursing response is the 15/15 approach: give 15 g of a rapid-acting carbohydrate, then recheck the blood glucose in 15 minutes. Examples include 4 oz of juice, glucose tablets, or regular soda if allowed by facility policy. The reason this works is simple: a fast sugar source raises blood glucose quickly, which is what the patient needs now.

After the nurse gives the carbohydrate, the next step is monitoring. Recheck the blood glucose in 15 minutes. If it is still low, repeat treatment per protocol. Once the blood glucose improves and the patient is stable, the nurse should make sure the patient gets a longer-acting carbohydrate or meal when available. That helps prevent the blood sugar from dropping again, especially since the insulin is already active.

The nurse should also assess why this happened. In this case, the likely cause is the timing mismatch between insulin lispro and food delivery. Lispro starts working quickly, so it should be given when the meal is ready or certain to arrive right away. This is a major medication safety point on the NCLEX and in practice. Giving rapid-acting insulin without timely food intake raises the risk for hypoglycemia.

Once the patient is stable, the nurse should document the event, report it according to unit policy, and review future insulin timing. The nurse should also continue to monitor for recurring symptoms such as tremor, sweating, tachycardia, confusion, headache, and weakness.

Why the Other Options Are Wrong

B. Hold the next scheduled dose of insulin glargine and document the episode.

This is not the priority. Insulin glargine is a long-acting basal insulin scheduled for the evening, not the cause of the immediate problem. The patient needs treatment for current hypoglycemia now, not a change to a later dose. Also, basal insulin decisions should be based on a broader assessment, not just one event.

C. Notify the provider immediately before taking any action because the blood glucose dropped after insulin administration.

This delays urgent treatment. Nurses should treat symptomatic hypoglycemia promptly using established protocols when the patient can safely swallow. The provider may need to be notified later, especially if episodes repeat or orders need adjustment, but the first action is to correct the low glucose.

D. Give 1 mg glucagon by intramuscular injection and place the patient in side-lying position.

Glucagon is used when the patient cannot take oral carbohydrates safely, such as when unconscious, seizing, or unable to swallow. This patient is awake, alert enough to follow commands, and can swallow. Oral rapid-acting carbohydrate is faster, simpler, and appropriate here.

Key Takeaways

• Rapid-acting insulin plus a delayed meal can cause hypoglycemia fast.
• If the patient is awake and can swallow, treat low blood glucose with 15 g of rapid-acting carbohydrate.
• Recheck blood glucose in 15 minutes and repeat treatment if needed per protocol.
• After recovery, give a meal or snack when available to prevent another drop.
• Priority comes before reporting. Treat first, then notify and document.

• On-shift mini-checklist:
• Confirm the glucose value and symptoms.
• Check whether the patient can swallow safely.
• Give fast carbohydrate right away if appropriate.
• Recheck in 15 minutes.
• Arrange food after the glucose improves.
• Review insulin timing before the next dose.

Quick Practice Extension

1. If this same patient became confused and could not swallow safely, what would the nurse do first?

2. What teaching should the nurse give staff and patients about timing rapid-acting insulin with meal delivery?

That is today’s NCLEX Question of the Day. The big lesson is not just knowing the drug class, but spotting when the treatment plan and the patient’s real-time condition no longer match. That is the kind of judgment safe nurses use every shift.
