The nurse has tested the pH of urine from a patient's newly created ileal conduit and obtained a result of 6.8. What is the nurse's best response to this assessment finding?
A) Obtain an order to increase the patient's dose of ascorbic acid.
B) Administer IV sodium bicarbonate as ordered.
C) Encourage the patient to drink at least 500 mL of water and retest in 3 hours.
D) Irrigate the ileal conduit with a dilute citric acid solution as ordered.
Ans: A
Feedback:
Because severe alkaline encrustation can accumulate rapidly around the stoma, the urine pH is kept below 6.5 by administration of ascorbic acid by mouth. An increased pH may suggest a need to increase ascorbic acid dosing. This is not treated by administering bicarbonate or citric acid, nor by increasing fluid intake.
