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