Final answer:
In the macroscopic examination of urine, specific gravity can be affected by temperature, glucose, and protein. If a urine sample has a 3+ glucose, the specific gravity will be increased by: b. 0.010
Step-by-step explanation:
If a urine sample has a 3+ glucose, the specific gravity will be increased by 0.010. Glucose is a solute that contributes to the overall concentration of solutes in urine. The increase in solute concentration, in this case, glucose, leads to a higher specific gravity value. Therefore, the correct answer is b) 0.010.
The relationship between solute concentration and specific gravity is based on the principles of osmolality and density. Specific gravity measures the concentration of solutes in a liquid compared to the density of pure water.
In the context of urine, an increase in solute concentration, such as glucose, will cause an elevation in specific gravity. This relationship is crucial in clinical diagnostics, where specific gravity is used as an indicator of the kidney's ability to concentrate urine and the overall hydration status of an individual.
Understanding the impact of different substances on specific gravity is essential for accurate interpretation of urine analysis results. In this case, the presence of glucose in the urine directly influences specific gravity, highlighting the interconnected nature of biochemical parameters in clinical assessments. The quantification of these relationships aids healthcare professionals in diagnosing and monitoring various conditions related to renal function and metabolic health.
