Nursing Implications

Assessment & Drug Effects

  • Monitor for S&S of increased airway resistance, especially in patient with asthma, bronchitis, emphysema, or COPD.
  • Monitor cardiac status, especially in those with known cardiac disease or dysfunction.
  • Monitor fluid status, especially in those at risk for dehydration.
  • Lab tests: Routine blood chemistry during long-term therapy.
  • Report S&S of excess cholinergic activity (e.g., diaphoresis, frequent urge to urinate, nausea and/or diarrhea).

Patient & Family Education

  • Do not drive or engage in potentially hazardous activities until response to drug is known.
  • Consult physician if confusion, dizziness, or faintness occur.
