Which term describes a solution such as 0.9% NaCl (normal saline) relative to red blood cells?

A.

Isotonic

B.

Exotonic

C.

Hypotonic

D.

Hypertonic

Answer and Explanation

The Correct Answer is A

A. Isotonic: An isotonic solution has the same solute concentration as blood plasma; thus, 0.9% NaCl does not cause cells to shrink or swell.

 

B. Exotonic: "Exotonic" is not a recognized term in fluid balance or physiology.

 

C. Hypotonic: A hypotonic solution (like 0.45% NaCl) has a lower solute concentration than blood, causing water to move into cells, possibly leading to swelling.

 

D. Hypertonic: A hypertonic solution (like 3% NaCl) has a higher solute concentration than blood, causing water to leave cells and leading to cell shrinkage.

Correct Answer is C

Explanation

A. Alkalosis and insomnia:

Alkalosis does not trigger sickling; acidosis (low pH) is more harmful. Insomnia alone is not a direct trigger.

B. Reduced stress and warm environmental temperature:

Reduced stress and warmth help prevent crises rather than cause them.

C. Acidosis and dehydration:

Acidosis promotes sickling of RBCs, and dehydration increases blood viscosity, both triggering vaso-occlusive crises.

D. High fat diet and hyperoxia:

A high-fat diet is linked to cardiovascular disease, and hyperoxia (excess oxygen) is not a trigger for sickling.
