Diabetes Mellitus (DM) is a prevalent, chronic metabolic condition characterized by the body’s impaired ability to regulate blood glucose levels. This dysfunction stems from ineffective insulin utilization, leading to hyperglycemia and disruptions in carbohydrate, fat, and protein metabolism. Effective nursing care for patients with diabetes relies heavily on accurate diagnosis and well-planned interventions. Understanding the relevant diabetes NANDA diagnoses is crucial for nurses to provide patient-centered and evidence-based care.
Understanding Diabetes Mellitus
Diabetes mellitus is not a single disease but a group of metabolic disorders sharing the common feature of hyperglycemia. The primary defect in diabetes is either the pancreas’s inability to produce enough insulin (Type 1 diabetes) or the body’s resistance to insulin (Type 2 diabetes), or both.
Types of Diabetes Mellitus
Diabetes mellitus is broadly classified into several types:
Type 1 Diabetes: Characterized by an autoimmune reaction that destroys pancreatic beta cells, which are responsible for insulin production. Genetic predisposition and viral infections are considered potential contributing factors.
Type 2 Diabetes: The most common form, developing gradually over time. It results from insulin resistance, where the body’s cells do not respond effectively to insulin. Lifestyle factors, genetics, and age play significant roles in its development.
Gestational Diabetes: Occurs during pregnancy in women who have not previously been diagnosed with diabetes. It typically resolves after childbirth, but it increases the mother’s risk of developing type 2 diabetes later in life and poses risks to the baby’s health.
Prediabetes: A precursor to type 2 diabetes, marked by blood glucose levels higher than normal but not yet meeting the criteria for a diabetes diagnosis. Prediabetes is defined by a fasting blood glucose level between 100-125 mg/dL.
Blood Glucose Imbalances: Hypoglycemia and Hyperglycemia
Maintaining stable blood glucose levels is vital in diabetes management. Imbalances in either direction can lead to acute and chronic complications.
Hypoglycemia (Low Blood Glucose): Defined as blood glucose levels below 70 mg/dL. It is a potentially dangerous condition requiring immediate intervention to prevent neurological damage.
Causes of Hypoglycemia
Hypoglycemia can be triggered by various factors, including:
- Excessive insulin dosage
- Inadequate carbohydrate intake
- Missed or delayed meals
- Strenuous physical activity
- Alcohol consumption
- Certain medications
- Hormonal fluctuations (puberty, menstruation)
- Environmental factors (hot and humid weather)
Hyperglycemia (High Blood Glucose): Refers to elevated blood glucose levels due to insufficient insulin in the bloodstream. Hyperglycemia is diagnosed when fasting blood glucose exceeds 125 mg/dL or when blood glucose is above 180 mg/dL one to two hours after eating.
Causes of Hyperglycemia
Hyperglycemia can result from:
- Dietary indiscretions (excessive carbohydrate intake)
- Physical inactivity
- Illness or infection
- Emotional stress
- Steroid medications
- Incorrect use of diabetes medications (insulin or oral agents)
- Insulin resistance progression
Nursing Assessment for Diabetes Mellitus
A comprehensive nursing assessment is the cornerstone of effective diabetes care. It involves gathering subjective and objective data to identify patient needs and formulate appropriate diabetes NANDA diagnoses.
Review of Health History: Subjective Data
The health history provides crucial insights into the patient’s experience with diabetes and potential risk factors.
1. General Symptoms: Assess for symptoms related to both hypoglycemia and hyperglycemia:
- Hypoglycemia Symptoms: Palpitations, tremors, diaphoresis (sweating), anxiety, confusion, dizziness, hunger.
- Hyperglycemia Symptoms: Polyuria (frequent urination), polydipsia (increased thirst), polyphagia (increased hunger), blurred vision, paresthesia (tingling or numbness in extremities), fatigue, headaches, balanitis (penile inflammation) in men.
- Gestational Diabetes Symptoms: Often asymptomatic, but may present with hyperglycemia symptoms: increased urination, hunger, thirst, blurred vision, nausea, and vomiting.
2. Diabetes Duration and Treatment History: Determine the duration of the diabetes diagnosis and current or past treatments. Long-term diabetes control significantly impacts the risk of complications.
3. Age at Diagnosis: Note the age of diagnosis, as type 1 diabetes often manifests in childhood or adolescence, while type 2 diabetes is more common in adults over 40.
4. Risk Factor Assessment: Investigate both non-modifiable and modifiable risk factors for diabetes.
-
Non-modifiable Risk Factors:
- Family history: Genetic predisposition increases diabetes risk.
- Race/Ethnicity: Certain ethnicities (Black, Hispanic, American Indian, Asian American) have higher type 2 diabetes prevalence.
- Age: Risk of prediabetes and type 2 diabetes increases with age.
- Autoimmune diseases: Predispose to type 1 DM and LADA (Latent Autoimmune Diabetes in Adults).
- Hormonal imbalances: Can contribute to gestational and type 2 diabetes.
-
Modifiable Risk Factors:
- Obesity and unhealthy diet: High-fat, high-calorie diets increase diabetes risk.
- Smoking: Smokers have a significantly higher risk of type 2 diabetes and complications.
- Excessive alcohol consumption: Can impair insulin sensitivity.
- Sedentary lifestyle: Lack of physical activity increases insulin resistance.
- Chronic conditions: Hypertension and hyperlipidemia increase diabetes risk and complications.
5. Yeast Infections: Inquire about recurrent yeast infections, as hyperglycemia promotes yeast overgrowth.
6. Diabetes-Related Complications: Assess for existing complications from diabetes:
- Cardiovascular Disease: Including coronary artery disease, angina, myocardial infarction, cerebrovascular accidents (stroke).
- Neuropathy: Nerve damage causing pain, numbness, tingling, and potentially leading to foot ulcers and amputations.
- Renal Disease (Nephropathy): Kidney damage potentially progressing to kidney failure.
- Retinopathy: Eye damage that can lead to blindness.
- Foot Damage: Ulcers, infections, and slow healing due to neuropathy and poor circulation.
- Depression: Common due to the challenges of managing diabetes, potentially exacerbating blood glucose control.
7. Blood Glucose Monitoring Records: Review home glucose monitoring records to identify patterns of hyper- or hypoglycemia.
Physical Assessment: Objective Data
Physical assessment provides observable signs and indicators of diabetes and its complications.
1. Vital Signs: Monitor blood pressure and respiratory rate. Hypertension is common in diabetes. Orthostatic hypotension may indicate autonomic neuropathy. Kussmaul respirations (deep, rapid breathing) suggest diabetic ketoacidosis (DKA).
2. Peripheral Pulses: Palpate dorsalis pedis and posterior tibialis pulses to assess for peripheral vascular disease.
3. Foot Assessment: Conduct a thorough foot exam, including sensory testing using a Semmes Weinstein monofilament, reflex testing, and vibration perception to detect neuropathy and risk of foot ulcers.
4. Weight Assessment: Note weight changes. Unexplained weight loss can occur in type 1 diabetes due to glycosuria and dehydration. Weight gain is common in type 2 diabetes and exacerbates insulin resistance.
Diagnostic Procedures
Diagnostic tests confirm diabetes and monitor its management.
1. Blood Glucose Testing:
-
Type 1 DM Diagnosis:
- Fasting plasma glucose ≥ 126 mg/dL
- Random plasma glucose ≥ 200 mg/dL with symptoms
- HbA1c ≥ 6.5%
-
Type 2 DM Diagnosis: Primarily based on fasting plasma glucose and HbA1c.
-
Prediabetes Diagnosis:
- Fasting blood sugar (FBS) 100-125 mg/dL
- 2-hour post-oral glucose tolerance test (OGTT) glucose 140-200 mg/dL
-
Gestational Diabetes Screening:
- 1-hour glucose challenge test (GCT) at 24-28 weeks gestation
- 3-hour OGTT for confirmation if GCT is elevated (≥ 140 mg/dL)
2. Other Lab Tests:
- Urine albumin: Detects early diabetic nephropathy.
- Serum lipid profile: Assesses cardiovascular risk.
- Thyroid function tests: Annual screening for hypothyroidism.
Nursing Interventions for Diabetes Mellitus
Nursing interventions aim to achieve glycemic control, prevent complications, and empower patients to manage their diabetes effectively. These interventions directly address identified diabetes NANDA diagnoses such as Risk for Unstable Blood Glucose Level and Ineffective Tissue Perfusion.
Glycemic Control
1. Patient Adherence and Education: Emphasize the importance of adherence to treatment plans and follow-up appointments. Provide comprehensive diabetes education, including the impact of diet, exercise, stress, and medications on blood glucose. Refer patients to diabetes nurse educators for individualized support.
2. Home Glucose Monitoring: Teach patients how to use home glucose monitoring devices and maintain accurate records. Continuous glucose monitors (CGMs) are valuable, particularly for patients on insulin pumps or those with hypoglycemia unawareness.
3. Target Glucose Levels: Aim for HbA1c < 7% and pre-meal blood glucose between 90-130 mg/dL to minimize long-term complications.
4. Diabetes Type-Specific Treatment:
- Type 1 DM Treatment: Insulin therapy (injections or pump), blood glucose monitoring, carbohydrate counting, and potentially pancreas or islet cell transplantation.
- Type 2 DM Treatment: Lifestyle modifications (diet and exercise), blood glucose monitoring, oral hypoglycemic agents, and potentially insulin therapy.
5. Insulin Administration Education: Provide thorough instruction on proper insulin administration techniques, including different insulin types, injection sites, and insulin pens.
6. Insulin Pump Management: Assist patients with wearable insulin pumps and educate on their use, maintenance, and troubleshooting. Consider closed-loop insulin delivery systems (artificial pancreas) for improved glucose control.
7. Oral Diabetes Medications Education: Educate patients about different classes of oral diabetes medications, their mechanisms of action, and potential side effects.
8. Meal Planning and Nutritional Guidance: Collaborate with patients to develop individualized meal plans emphasizing balanced nutrition, carbohydrate control, and portion management. Refer to registered dietitians or nutritionists for comprehensive dietary education and carbohydrate counting instruction.
9. Physical Activity Promotion: Encourage regular physical activity (at least 150 minutes of moderate-intensity exercise per week) to improve insulin sensitivity and lower blood glucose. Advise patients to consult their healthcare provider before starting a new exercise program.
10. Weight Management: Support weight loss in overweight or obese patients with type 2 diabetes or prediabetes, as even modest weight reduction (5-7%) can improve glycemic control.
11. Gestational Diabetes Management: Manage blood glucose levels during pregnancy through monitoring, dietary modifications, and potentially insulin or oral hypoglycemic agents. Monitor maternal and fetal blood glucose levels during labor and delivery.
12. Diabetes Prevention: Promote healthy lifestyles for individuals with prediabetes to prevent progression to type 2 diabetes. This includes weight management, regular exercise, and a balanced diet. Metformin and other medications may be considered in high-risk individuals.
13. Referral to Specialists: Refer patients to endocrinologists or diabetologists for specialized diabetes care and management of complex cases.
Complication Prevention
1. Medical Alert Identification: Advise patients to wear a medical alert bracelet or necklace indicating they have diabetes, especially in case of emergencies like hypoglycemia or DKA.
2. Ophthalmologic Care: Refer patients for annual eye exams by an ophthalmologist to screen for diabetic retinopathy, cataracts, and glaucoma.
3. Vaccination Recommendations: Encourage recommended vaccinations, as diabetes can impair immune function and increase infection risk.
4. Foot Care Education: Provide detailed foot care education, emphasizing daily foot inspections, proper hygiene, and professional podiatric care for nail trimming and management of neuropathy.
5. Blood Pressure and Cholesterol Management: Implement strategies to manage blood pressure and cholesterol levels through lifestyle modifications and medications to reduce cardiovascular risk.
6. Oral Hygiene: Educate patients about meticulous oral hygiene practices, including regular brushing and flossing, and routine dental check-ups to prevent gum disease.
7. Smoking Cessation: Strongly encourage smoking cessation due to the significantly increased risk of diabetes complications in smokers.
8. Moderate Alcohol Consumption: Advise patients to consume alcohol in moderation and with food, as alcohol can affect blood glucose levels.
9. Stress Management: Teach stress-coping techniques, as chronic stress can negatively impact blood glucose control.
10. Diabetes Nurse Educator Collaboration: Coordinate care with diabetes nurse educators to provide ongoing support, education, and self-management training.
11. DSMES Programs: Recommend participation in Diabetes Self-Management Education and Support (DSMES) programs to improve self-efficacy, health outcomes, and quality of life.
Diabetes NANDA Diagnosis and Nursing Care Plans
Identifying appropriate diabetes NANDA diagnoses is essential for developing individualized nursing care plans. Here are examples of common diabetes NANDA diagnoses and associated care plan components:
1. Decreased Cardiac Output
Nursing Diagnosis: Decreased Cardiac Output related to cellular dysfunction secondary to insulin resistance or uncontrolled blood glucose levels.
Related Factors: Elevated blood glucose levels, impaired myocardial contractility, increased afterload, decreased myocardial oxygenation, increased cardiac inflammation.
Evidenced by: Tachycardia, tachypnea, dyspnea, orthopnea, reduced oxygen saturation, hypotension, dysrhythmias, fatigue, altered level of consciousness, anxiety, decreased activity tolerance, edema, decreased peripheral pulses, decreased urine output.
Expected Outcomes:
- Patient will demonstrate adequate cardiac output, as evidenced by stable vital signs, strong peripheral pulses, and adequate urine output.
- Patient will be free from symptoms of dyspnea, palpitations, and altered mentation.
- Patient will maintain intact skin without evidence of breakdown.
Nursing Interventions:
- Monitor heart rate, blood pressure, and EKG.
