Answer to Question 1

B
Feedback:
Lidocaine has a rapid effect, and, when combined with epinephrine, this effect is prolonged. Epinephrine can promote vasoconstriction, not vasodilation, and it neither prevents adverse effects nor blocks afferent nerve pathways.

Answer to Question 2

C
Feedback:
The FDA has issued a black box warning stating that patients taking desmopressin can develop hyponatremia, leading to seizures. Consequently, assessment of sodium levels takes precedence over hematocrit, calcium, and platelet levels.
