What happens when a hypertonic IV solution is administered to a client?

A.

Fluid will be pushed in the interstitial spaces

B.

Fluid will be pulled out of the cells and into the blood stream.

C.

Fluid will be pushed out of the blood stream into the extravascular spaces.

D.

Fluid will be pulled out of the bloodstream into the cells

Answer and Explanation

The Correct Answer is B

A. Fluid will be pushed into the interstitial spaces. Hypertonic solutions draw water into the bloodstream, not into tissues.

B. Fluid will be pulled out of the cells and into the bloodstream: Hypertonic solutions (e.g., 3% NaCl, D10W) have a higher osmolarity than blood plasma. This pulls fluid from cells into the intravascular space, causing cell shrinkage and increasing blood volume.

C. Fluid will be pushed out of the bloodstream into extravascular spaces. This describes a hypotonic solution’s effect.

D. Fluid will be pulled out of the bloodstream into the cells. This describes an isotonic or hypotonic effect.

A. "We'll find out if any medications, such as steroids, are interfering with your kidney function." Some medications affect kidney function, but creatinine primarily measures kidney efficiency, not drug interactions.
