lumen (see Fig. 69-9).
b. Ewald tube: A single-lumen large tube
used for rapid 1-time irrigation and
evacuation
L. Urinary and renal tubes
1. Types of urinary catheters
a. Single lumen: Usually used for straight
catheterization to empty the client’s
bladder, obtain sterile urine specimens,
or check the residual amount of urine
after the client voids
b. Double lumen: Used when an
indwelling catheter is needed for
continuous bladder drainage; one
lumen is for drainage and the other is
for balloon inflation.
c. Triple lumen: Used when bladder
irrigation and drainage is necessary; 1
lumen is for instilling the bladder
irrigant solution, 1 lumen is for
continuous bladder drainage, and 1
lumen is for balloon inflation.
d. Strict aseptic technique is necessary for
insertion and care of the catheter.
2. Routine urinary catheter care
a. Use gloves and wash the perineal area
with warm soapy water.
b. With the nondominant hand, pull back
the labia or foreskin to expose the
meatus (in the adult male, return the
foreskin to its normal position).
c. Cleanse along the catheter with soap
and water.
d. Anchor the catheter to the thigh.
e. Maintain the catheter bag below the
level of the bladder.

3. Ureteral and nephrostomy tubes (Fig. 69-9)

a. Never clamp the tube.
b. Maintain patency.
c. Irrigate only if prescribed by the PHCP,
using strict aseptic technique; a
maximum of 5 mL of sterile NS is
instilled slowly and gently.
d. If patency cannot be established with
the prescribed irrigation, notify the
PHCP immediately.
