Nursing implications

Nursing assessment

  • Monitor blood pressure prior to and periodically during therapy.
  • Hypercholesterolemia: Obtain a diet history, especially with regard to fat consumption.
  • Menopausal symptoms: Assess the frequency and intensity of hot flashes prior to and periodically during therapy.
  • Lab Test Considerations: Monitor blood glucose, lipid profile, hormones, and thyroid function before and periodically during therapy.

Potential Nursing Diagnoses

Deficient knowledge, related to diet and medication regimen (Patient/Family Teaching)


  • Oral: Administer as directed.

Patient/Family Teaching

  • Instruct patient to take as directed.
  • Instruct patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult with health care professional before taking other medications.

Evaluation/Desired Outcomes

  • Decrease in frequency and intensity of hot flashes.
  • Reduction in serum cholesterol levels.
