Type 1 Diabetes Management: Understanding Blood Sugar Levels and Their Implications

A diagnosis of Type 1 Diabetes Mellitus (Type 1 DM) is a significant life change, and proper management is crucial for the well-being of the individual. Mr. Wesley, a newly diagnosed Type 1 DM patient, is under the care of a home health nurse. The doctor’s orders include a specific diet plan, insulin administration, and regular blood sugar monitoring. During the nurse’s visit, an unexpected blood sugar reading of 50 mg/dL is observed. In this article, we will explore what this blood sugar level signifies and what the nurse would expect from Mr. Wesley in this situation.

Understanding Type 1 Diabetes

Type 1 DM is an autoimmune condition in which the body’s immune system mistakenly attacks and destroys insulin-producing beta cells in the pancreas. This results in an absolute deficiency of insulin, the hormone responsible for regulating blood sugar. Individuals with Type 1 DM must rely on exogenous insulin (insulin from an external source) to maintain proper blood sugar control.

The Doctor’s Orders

Mr. Wesley’s doctor has provided specific orders for his diabetes management:

  1. 1200 Calorie ADA Diet: The doctor has prescribed a 1200 calorie diet following the American Diabetes Association (ADA) guidelines. This diet aims to help control blood sugar levels through controlled carbohydrate intake and portion management.
  2. 15 Units of NPH Insulin Before Breakfast: NPH insulin is a longer-acting insulin that helps maintain blood sugar levels throughout the day. By administering it before breakfast, Mr. Wesley can better manage his blood sugar levels.
  3. Check Blood Sugar QID (Four Times a Day): The doctor has advised Mr. Wesley to monitor his blood sugar four times a day to ensure it remains within a safe and target range. This monitoring provides valuable insights into the effectiveness of his treatment plan.

Interpreting a Blood Sugar Reading of 50 mg/dL

When the nurse observes a blood sugar reading of 50 mg/dL in Mr. Wesley, it is considered low, indicating hypoglycemia. Hypoglycemia is defined as a blood sugar level below 70 mg/dL, and it can cause a range of symptoms, including:

  • Shakiness
  • Sweating
  • Rapid heartbeat
  • Dizziness
  • Irritability
  • Confusion
  • Hunger

In more severe cases, hypoglycemia can lead to loss of consciousness and seizures. A blood sugar reading of 50 mg/dL is a cause for concern and requires prompt action.

Expectations for Mr. Wesley

When the nurse observes a blood sugar level of 50 mg/dL in Mr. Wesley, several expectations come into play:

  1. Immediate Treatment: The nurse should promptly address the hypoglycemia by providing Mr. Wesley with a fast-acting source of glucose. This may include glucose tablets, juice, or any preferred source of sugar.
  2. Reevaluation: After treatment, Mr. Wesley’s blood sugar level should be reevaluated to ensure it returns to a safe range. Repeat monitoring is essential to confirm the effectiveness of the intervention.
  3. Discussion and Education: The nurse should discuss with Mr. Wesley the potential causes of hypoglycemia. This may include factors like too much insulin, delayed meals, or increased physical activity. Education on recognizing and preventing hypoglycemia is critical for Mr. Wesley’s long-term diabetes management.
  4. Review of Medication and Diet Plan: The nurse should also review Mr. Wesley’s medication administration and dietary choices to identify any potential issues that may have contributed to the low blood sugar.
  5. Documentation: Accurate and thorough documentation of the incident, including Mr. Wesley’s response to treatment, is essential for future reference and care planning.


A blood sugar reading of 50 mg/dL in Mr. Wesley, a newly diagnosed Type 1 DM patient, signifies hypoglycemia and is a cause for concern. It highlights the importance of careful blood sugar monitoring, adherence to treatment plans, and the need for prompt and appropriate action in the event of low blood sugar. As Mr. Wesley continues his diabetes management journey, he will learn to recognize and address hypoglycemia effectively, ensuring better control of his condition and overall well-being.
