Final answer:
The injected solution was not isotonic, but osmotic, as it caused the patient's red blood cells to burst.
Step-by-step explanation:
The correct answer is b. False, the solution was osmotic.
Isotonic solutions have the same concentration of solutes as the cells in the body. If the solution injected into the patient's bloodstream caused the red blood cells to burst, it means that the solute concentration in the solution was greater than the concentration inside the cells, making it hypertonic. In this case, the solution was not isotonic and was osmotic, causing the red blood cells to burst.
It's important to note that the bursting of red blood cells can be a dangerous condition and should be addressed by a healthcare professional.
