Questions: The dilution of the arterial preservative solution with interstitial fluids is known as: (A) primary dilution (B) secondary dilution (C) primary injection (D) co-injection

The answer is (B): secondary dilution.

Explanation for each option:

(A) Primary dilution: This refers to the initial mixing of the preservative solution with the blood and other fluids in the vascular system immediately upon injection. It is not the correct term for the dilution with interstitial fluids.

(B) Secondary dilution: This is the correct term for the dilution of the arterial preservative solution with interstitial fluids. It occurs after the primary dilution and involves the further mixing of the solution as it diffuses into the tissues.

(C) Primary injection: This term refers to the initial injection of the preservative solution into the body. It does not describe the dilution process.

(D) Co-injection: This term refers to the simultaneous injection of another fluid or chemical along with the primary preservative solution. It is not related to the dilution process with interstitial fluids.

In summary, the correct answer is (B) secondary dilution, as it specifically describes the process of the arterial preservative solution mixing with interstitial fluids.
