A client with protracted nausea and vomiting has been receiving intravenous solution at 125 ml/h for the past several hours
The administration of this solution has resulted in an increase in blood pressure because the water in the solution has passed through the semipermeable membrane of blood cells, causing them to swell. This client has been receiving: A) Packed red blood cells
B) An isotonic solution
C) A hypertonic solution
D) A hypotonic solution
D
Feedback:
Because hypotonic solutions are dilute, the water in the solution passes through the semipermeable membrane of blood cells, causing them to swell. This temporarily increases blood pressure as it expands the circulating volume. Hypertonic solutions draw water out of body cells while isotonic solutions have little effect on the distribution of body fluids. Blood transfusions do not cause the entry of water into body cells.
