Answer:
The correct answer is - atropine and epinephrine.
Explanation:
CPCR is standing for the cardiopulmonary cerebral resuscitation which is specific attempts or to retrieve the cardiac arrest or respiratory arrest patients so they or they might experience a severe critical condition of the drop in perfusion pressure.
Atropine and epinephrine are the two drugs that are used in administration first during CPCR, as atropine blocks the action of vagus nerves that lead in an increase of firing in the SA node of the heart whereas the epinephrine drug acts on the complete myocardium that includes AV node, SA node, and nerves.
Thus, the correct answer is - atropine and epinephrine.
