Question 5 of 15

Sorry, that is wrong.

When a patient has atypical pseudocholinesterase, it represents a relative contraindication to the use of esters.

Plasma pseudocholinesterase is primarily responsible for the hydrolysis of esters to para-aminobenzoic acid (PABA). Patients who have atypical pseudocholinesterase may not be able to biotransform esters at the usual rate. This could lead to higher levels of the ester drug in their blood.

These patients should receive amides when administration of local anesthetics are necessary.
