NURSING IMPLICATIONS

Assessment & Drug Effects

  • Observe patients receiving parenteral drug carefully; closely monitor BP and vital signs. Sudden death from cardiac arrest has been reported.
  • Monitor BP during periods of diuresis and through period of dosage adjustment.
  • Observe older adults closely during period of brisk diuresis. Sudden alteration in fluid and electrolyte balance may precipitate significant adverse reactions. Report symptoms to physician.
  • Lab tests: Obtain frequent blood count, serum and urine electrolytes, CO2, BUN, blood sugar, and uric acid values during first few months of therapy and periodically thereafter.
  • Monitor for S&S of hypokalemia (see Appendix F).
  • Monitor I&O ratio and pattern. Report decrease or unusual increase in output. Excessive diuresis can result in dehydration and hypovolemia, circulatory collapse, and hypotension. Weigh patient daily under standard conditions.
  • Monitor urine and blood glucose & HbA1C closely in diabetics and patients with decompensated hepatic cirrhosis. Drug may cause hyperglycemia.
  • Note: Excessive dehydration is most likely to occur in older adults, those with chronic cardiac disease on prolonged salt restriction, or those receiving sympatholytic agents.

Patient & Family Education

  • Consult physician regarding allowable salt and fluid intake.
  • Ingest potassium-rich foods daily (e.g., bananas, oranges, peaches, dried dates) to reduce or prevent potassium depletion.
  • Learn S&S of hypokalemia (see Appendix F). Report muscle cramps or weakness to physician.
  • Make position changes slowly because high doses of antihypertensive drugs taken concurrently may produce episodes of dizziness or imbalance.
  • Avoid replacing fluid losses with large amounts of water.
  • Avoid prolonged exposure to direct sun.
  • Do not breast feed while taking this drug.
