Nursing implications

Nursing assessment

  • BP should be monitored periodically throughout therapy.
  • Monitor fluid intake and output ratios and weekly weight. Report significant discrepancies or steady weight gain to physician or other health care professional.
  • Monitor pattern and amount of vaginal bleeding (pad count).
  • Lab Test Considerations: Monitor hepatic function before and periodically throughout therapy. May cause increased serum glucose and alkaline phosphatase levels. May decrease pregnanediol excretion concentrations.
    • May cause increased LDL and decreased HDL and amino acid concentrations.

Potential Nursing Diagnoses

Sexual dysfunction (Indications)


  • Intramuscular: Administer deep IM. Use dry needle and syringe to prevent clouding of solution.

Patient/Family Teaching

  • Advise patient to report signs and symptoms of fluid retention (swelling of ankles and feet, weight gain), thromboembolic disorders (pain, swelling, tenderness in extremities, headache, chest pain, blurred vision), depression, or hepatic dysfunction (yellowed skin or eyes, pruritus, dark urine, light-colored stools) to health care professional.
    • Instruct patient to notify health care professional if change in vaginal bleeding pattern or spotting occurs.
    • Instruct patient to stop taking medication and notify health care professional if pregnancy is suspected.
    • Caution patient to use sunscreen and protective clothing to prevent increased pigmentation.
    • Instruct patient to practice good oral hygiene, have teeth cleaned regularly, and notify dentist if tenderness, swelling, or bleeding gums occur.
    • Advise patients with diabetes to monitor serum glucose carefully and report any abnormalities to health care professional; may decrease glucose tolerance.
    • Advise patient to notify health care professional of medication regimen before treatment or surgery.
    • Emphasize the importance of routine follow-up physical exams, including BP; ophthalmic, breast, abdominal, and pelvic examinations; and PAP smears.
  • Amenorrhea or Functional Uterine Bleeding: Explain 28-day cyclic dosage schedule. Cyclic therapy begins after 4 days of desquamation from initial dose or 21 days after injection if bleeding did not occur. Explain that several months of estrogen therapy may be required before menstruation occurs.

Evaluation/Desired Outcomes

  • Development of normal cyclic menses.
  • Control of the spread of advanced metastatic uterine cancer..
