priority assessment before administration?
A) Respiratory rate
B) Blood pressure
C) Pain level
D) Heart rate

A) ACE inhibitors
B) Beta-blockers
C) Calcium channel blockers
D) Diuretics

mechanisms?
A) Decreasing gastric acid secretion
B) Increasing gastric mucosal protection
C) Neutralizing stomach acid
