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. 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. A specific gravity higher than 1.010 can mean fluid intake is not high enough, and a pH of less than 7 means acidosis.
2. A specific gravity higher than 1.010 can mean fluid intake is not high enough.
3. A specific gravity higher than 1.010 can mean fluid intake is not high enough, and a pH of less than 7 means acidosis.
4. Because the breakdown of malignant cells releases intracellular components into the blood, and electrolyte imbalance causes metabolic acidosis, the patient should remain well hydrated, with the urine specific gravity at less than 1.010 and the pH at 7–7.5.

A 16-year-old girl has broken her arm while snowboarding. When she arrives at hospital, she is shocked at the amount of swelling at the injury site
Which of the following statements best explains the physiological rationale for her swelling? A) Migration and proliferation of mast cells, neutrophils, and platelets to the injury site occupy an increased volume of tissue. B) Potent vasodilation increases the total volume of vascular space at the site of inflammation. C) Osmotic flow of plasma into the intravascular space causes increased blood volume and interstitial fluid. D) Loss of plasma proteins causes an increase in interstitial osmotic pressure.
