The nurse is monitoring the urine specific gravity and pH on a child receiving chemotherapy. The nurse will try to maintain the urine values at
1. spec gravity 1.030;pH 6.
2. spec gravity 1.030;pH 7.5.
3. spec gravity 1.005;pH 6.
4. spec gravity 1.005;pH 7.5.
Answer:4
Rationale:Because the breakdown of malignant cells releases intracellular components into the blood and electrolyte imbalance causes metabolic acidosis, the urine specific gravity should remain at less than 1.010 and the pH at 7 to 7.5. A specific gravity higher than 1.010 can mean fluid intake is not high enough, and a pH of less than 7 means acidosis.
