Urinary pH is not affected by the:

• A. Patient's diet
• B. Presence of crystals in the urine
• C. Presence of bacteria in the urine
• D. Patient's acid-base status

Answer: (B)

Urine pH reflects how the body handles hydrogen ions and the overall acid-base/urinary buffering status, so it changes with what you eat and with the patient’s acid-base condition. Diet can shift urinary acidity or alkalinity, and metabolic or respiratory disturbances adjust how much acid the kidneys must excrete, altering pH. Bacteria that produce urease raise urine pH by breaking down urea into ammonia, so infections can also shift pH upward. The presence of crystals, however, is a consequence of the urine environment (pH, concentration of solutes) and does not themselves change the pH in a meaningful way.
