A nurse assesses a client after administering a prescribed beta blocker. Which assessment should the nurse expect to find?
a. Blood pressure increased from 98/42 mm Hg to 132/60 mm Hg
b. Respiratory rate decreased from 25 breaths/min to 14 breaths/min
c. Oxygen saturation increased from 88% to 96%
d. Pulse decreased from 100 beats/min to 80 beats/min
ANS: D
Beta blockers block the stimulation of beta1-adrenergic receptors. They block the sympathetic (fight-or-flight) response and decrease the heart rate (HR). The beta blocker will decrease HR and blood pressure, increasing ventricular filling time. It usually does not have effects on beta2-adrenergic receptor sites. Cardiac output will drop because of decreased HR.
