Which of the following solutions is hypertonic with respect to blood?
A) 0.5% (m/v) NaCl
B) 0.7% (m/v) NaCl
C) 4.5% (m/v) glucose
D) 7.6% (m/v) glucose

Quizplus · Accepted Answer

A solution is hypertonic if it has a higher solute concentration than the reference solution, which in this case is blood. Glucose is a non-electrolyte solute and exerts an osmotic pressure similar to NaCl. A 7.6% (m/v) glucose solution is hypertonic compared to blood, whereas 0.5% (m/v) and 0.7% (m/v) NaCl solutions are hypotonic and 4.5% (m/v) glucose solution is isotonic.
