Keeping the urine --- will keep struvite crystals dissolved in solution.

Keeping the urine --- will keep struvite crystals dissolved in solution.

• A. Basic
• B. Isosthenuric
• C. Dilute
• D. Acidic

Answer: (D)

The main idea is how urine pH affects struvite crystals. Struvite tends to form in alkaline urine, especially when bacteria produce ammonia and raise the pH. Keeping urine acidic lowers the pH and increases struvite solubility, helping to dissolve crystals that may be present. The other factors listed (a basic environment, a normal-fixed specific gravity, or a dilute urine) don’t specifically promote dissolution of struvite crystals the way an acidic environment does.
