The nurse is teaching a client to prevent future urinary tract infections (UTIs). What factor is most important to emphasize as the potential cause?
a. Poor hygiene
b. Constipation
c. Urinary stasis
d. Congenital anomalies
ANS: C
Urinary stasis is the single most important host factor that influences the development of UTIs. Urine is usually sterile but at body temperature provides an excellent growth medium for bacteria. Poor hygiene can be a contributing cause, especially in females because their short urethras predispose them to UTIs. Urinary stasis then provides a growth medium for the bacteria. Intermittent constipation contributes to urinary stasis. A full rectum displaces the bladder and posterior urethra in the fixed and limited space of the bony pelvis, causing obstruction, incomplete micturition, and urinary stasis. Congenital anomalies can contribute to UTIs, but urinary stasis is the primary factor in many cases.
