Nursing implications
Nursing assessment
- Observe for signs and symptoms of hypoglycemic reactions (sweating, hunger, weakness, dizziness, tremor, tachycardia, anxiety), especially in patients taking insulin or other hypoglycemic agents.
- Monitor BP after initiating and periodically during therapy; may cause hypotension.
- Lab Test Considerations: Monitor serum glucose and glycosylated hemoglobin periodically during therapy to evaluate effectiveness of treatment.
- Evaluate renal function prior to starting and periodically during therapy; may cause ↑serum creatinine and ↓ eGFR.
- May cause ↑ LDL cholesterol.
- May cause an ↑ hematocrit and serum phosphorous.
- Will cause urine to test positive for glucose.
Overdose is manifested by symptoms of hypoglycemia. Mild hypoglycemia may be treated with administration of oral glucose. Treat severe hypoglycemia with IV D50W followed by continuous IV infusion of more dilute dextrose solution at a rate sufficient to keep serum glucose at approximately 100 mg/dL.
Potential Nursing Diagnoses
Imbalanced nutrition: more than body requirements (Indications)Noncompliance (Patient/Family Teaching)
Implementation
- high alert: Accidental administration of oral hypoglycemic agents to non-diabetic adults and children has resulted in serious harm or death. Before administering, confirm that patient has Type 2 diabetes.
- Patients stabilized on a diabetic regimen who are exposed to stress, fever, trauma, infection, or surgery may require administration of insulin.
- Oral: Administer once daily in the morning without regard to food.
Patient/Family Teaching
- Instruct patient to take medication at same time each day. Take missed doses as soon as remembered unless almost time for next dose; do not double doses. Advise patient to read Medication Guide before starting and with each Rx refill in case of changes.
- Explain to patient that this medication controls hyperglycemia but does not cure diabetes. Therapy is long term.
- Inform patient dapagliflozin may cause dehydration and hypotension. Maintain adequate hydration and notify health care professional if dizziness, fainting, weakness or orthostatic hypotension occur.
- Advise patient to notify health care professional if signs and symptoms of genital mycotic infections; females (vaginal odor, white or yellowish vaginal discharge, vaginal itching), males (rash or redness of glans or foreskin of penis, foul smelling discharge from penis, pain in skin around penis) occur. Instruct patient on treatment options and when to notify health care professional.
- Review signs of hypoglycemia and hyperglycemia with patient. If hypoglycemia occurs, advise patient to drink a glass of orange juice or ingest 2–3 tsp of sugar, honey, or corn syrup dissolved in water or an appropriate number of glucose tablets and notify health care professional.
- Encourage patient to follow prescribed diet, medication, and exercise regimen to prevent hypoglycemic or hyperglycemic episodes.
- Instruct patient in proper testing of serum glucose and ketones. These tests should be closely monitored during periods of stress or illness and health care professional notified if significant changes occur.
- Advise patient to inform health care professional of medication regimen prior to treatment or surgery.
- Advise patient to notify health care professional promptly if signs and symptoms of hypersensitivity reactions (rash; raised red patches on skin; swelling of face, lips, tongue, throat; difficulty breathing or swallowing) or bladder cancer (blood or red color in urine, painful urination) occur.
- Insulin is the recommended method of controlling blood sugar during pregnancy. Counsel female patients to use a form of contraception other than oral contraceptives and to notify health care professional promptly if pregnancy is planned or suspected. May cause fetal harm in 2nd or 3rd trimester.
- Advise patient to carry a form of sugar (sugar packets, candy) and identification describing disease process and medication regimen at all times.
- Emphasize the importance of routine follow-up exams.
Evaluation/Desired Outcomes
- Control of blood glucose levels without the appearance of hypoglycemic or hyperglycemic episodes.
