Unstable blood glucose, characterized by fluctuations outside the normal range, encompassing both hyperglycemia and hypoglycemia, is a significant health concern. It’s crucial to understand that unstable blood glucose isn’t solely indicative of diabetes. Transient conditions like dehydration or pregnancy can also disrupt blood sugar levels, typically resolving once the underlying cause is addressed.
However, for individuals with diabetes, managing glucose levels is paramount. Uncontrolled diabetes can lead to severe long-term complications affecting vital organs such as the heart, kidneys, eyes, and nerves. Therefore, nurses play a vital role in identifying potential causes of unstable glucose, educating patients and their families, and providing resources for effective prevention and management.
Note on Terminology: It’s important to acknowledge that the nursing diagnosis “Risk for Unstable Blood Glucose” has been updated by NANDA International to “Risk for Ineffective Blood Glucose Pattern Self-Management.” While this article primarily uses the former term for broader understanding and familiarity, nurses should be aware of the current NANDA-I terminology.
Risk Factors Associated with Unstable Blood Glucose
Identifying risk factors is the first step in preventing unstable blood glucose. These factors can be broadly categorized and include:
- Denial of Diagnosis: Lack of acceptance of a diabetes diagnosis can lead to poor self-management and increased risk.
- Deficient Knowledge: Inadequate understanding of diabetes, its management, and treatment regimens is a major risk factor.
- Poor Adherence to Diabetes Management: Inconsistent medication intake, blood glucose monitoring, or dietary compliance significantly elevates the risk.
- Financial Strain: Limited financial resources can hinder access to medications, supplies, and healthy food, impacting glucose control.
- Dietary Intake: Unhealthy eating patterns, including excessive carbohydrate intake or inconsistent meal schedules, contribute to glucose instability.
- Weight Changes: Significant weight gain or loss can affect insulin sensitivity and glucose regulation.
- Pregnancy: Hormonal changes during pregnancy can lead to gestational diabetes and unstable blood glucose.
- Activity Level: Both sedentary lifestyles and excessive exercise without proper management can disrupt glucose balance.
- Stress: Physical and emotional stress can trigger hormonal responses that elevate blood glucose levels.
- Developmental Level: Age-related factors, such as growth spurts in adolescence or age-related physiological changes, can influence glucose stability.

Important Note: As a risk diagnosis, “Risk for Unstable Blood Glucose” is identified before the problem occurs. Nursing interventions are therefore focused on proactive prevention strategies.
Expected Outcomes for Nursing Care
Effective nursing care planning sets clear goals and expected outcomes. For “Risk for Unstable Blood Glucose,” common goals include:
- Patient Education: The patient will be able to identify personal factors that increase their risk of experiencing unstable blood glucose levels.
- Glucose Control: The patient will maintain blood glucose levels within the normal target range as recommended by healthcare providers.
- Self-Monitoring Skills: The patient will accurately demonstrate the correct technique for monitoring their blood glucose levels using a glucometer.
Comprehensive Nursing Assessment
A thorough nursing assessment is crucial for identifying individual risks and tailoring interventions. This involves gathering both subjective and objective data related to the patient’s condition.
1. Identify Risk-Increasing Factors:
- Explore potential triggers for unstable glucose, such as medication access issues, dietary irregularities (overeating or undereating), obesity, inadequate or excessive exercise, adolescent growth spurts, and pregnancy.
2. Evaluate Disease Understanding:
- Assess the patient’s knowledge of diabetes through open-ended questions and discussions.
- Inquire about their understanding of their medications (insulin or oral antidiabetics), the necessity of medication, proper glucose monitoring techniques, and the recognition of hyperglycemia and hypoglycemia symptoms. This helps pinpoint knowledge deficits and guide patient education.
3. Assess for Nonadherence:
- Investigate potential nonadherence to prescribed regimens.
- Ask about missed medication doses, consistency in glucose monitoring, and dietary adherence. Questions like, “How many insulin doses have you missed in the past two weeks?” or “Describe your typical daily diet” can be informative.
4. Medication Review:
- Conduct a comprehensive medication review, including prescription, over-the-counter drugs, and supplements.
- Identify medications that can potentially interfere with glucose levels. Examples include antidepressants, corticosteroids, oral contraceptives, certain antibiotics, some heart and blood pressure medications, and cold remedies.
5. Dietary Pattern Assessment:
- Evaluate the patient’s diet and eating habits.
- Inquire about meal frequency and consistency, and the types of foods consumed. Irregular eating patterns can significantly impact glucose control. Missed meals can lead to hypoglycemia, while high-carbohydrate and sugary diets can cause hyperglycemia.
6. Alcohol Intake Evaluation:
- Assess the patient’s alcohol consumption habits.
- Explain that alcohol affects liver function, the primary organ responsible for glucose stabilization. When the liver metabolizes alcohol, its ability to regulate glucose can be compromised, potentially leading to hypoglycemia, especially on an empty stomach or in combination with diabetes medications.
7. Family Support Assessment:
- Evaluate the patient’s social support system, particularly family support.
- Identify any lack of support that might contribute to difficulties in obtaining medications, administering insulin, or preparing appropriate meals.
8. Monitor Hemoglobin A1C (HbA1c):
- Review HbA1c results, which reflect average blood glucose levels over the preceding two to three months.
- Explain that HbA1c is a valuable tool for monitoring the long-term effectiveness of diabetes management and treatment adjustments. The general target HbA1c for adults with diabetes is typically below 7%.
