NURSING IMPLICATIONS
ASSESSMENT
Assess patient for symptoms of benign prostatic hypertrophy (BPH) (urinary hesitancy, feeling of incomplete bladder emptying, interruption in urinary stream, impairment in size and force of urinary stream, terminal urinary dribbling, straining to start flow, dysuria, urgency) before and periodically throughout therapy.
Rectal exams prior to and periodically throughout therapy to assess prostate size are recommended.
POTENTIAL NURSING DIAGNOSES
Urinary elimination, impaired (Indications).
Knowledge, deficient, related to medication regimen (Patient/Family Teaching).
IMPLEMENTATION
Take on a full stomach to minimize GI effects.
PATIENT/FAMILY TEACHING
Advise patients to start therapy with this herbal supplement only after evaluation by a health care provider who will provide continued follow up care.
Inform patients that saw palmetto does not alter the size of the prostate but still should relieve the symptoms associated with BPH.
Tell patients that taking this herbal supplement with food should reduce the GI effects and make it easier to tolerate.
EVALUATION
Clinical response to therapy can be evaluated by:
Decrease in urinary symptoms of BPH.
