ADE: heart failure & negative chronotropic (causing slowing of the heart rate)
Contraindications: second-or third-degree heart block, & cardiogenetic shock,
severe bradycardia, heart failure, or hypotension, & asthma

RN implication: monitor BP & HR prior of given & 2-4 hours after the first dose,
withhold atenolol & notify the prescriber for a resting HR of 60 beats/min & or
systolic BP less than 90 mm Hg. The use of betablocker in pts w/diabetes can mask
the early warning S/ of hypoglycemic
Pts teaching: do not take abruptly (may cause rebound tachycardia), & move
slowly from a standing to a sitting position, take at the same time each & avoid
drinking large amount of orange juice
Lab tests: check blood sugar level if diabetes
It is important to note that nonselective beta-adrenergic blockers should not be used
in pts w/ variant angina because they are ineffective & may increase the tendency to
induce coronary vasospasm.
Cardio selective beta blockers (MEBA)
Metoprolol
Esmol
Bisoprolol
Atenolol
II. Nursing implication for patient allergic to a certain drug?
Stop the drug and administer an epi-pen and check the severity of the allergy
Bile acid sequestrants Cholestyramine (Questran, prevalite) (Colesevelam, colestipol)
MOA: binds bile acid in the intestinal lumen, cause the bile acid to excrete in feces,
preventing recirculation in the liver.
(We store cholesterol in the liver, with this meds the cholesterol doesn’t get store in the
liver, so the liver produces more bile acid to decreases the cholesterol.)
USE: mainly reduces LDL level, only a minimal of HDL & no effect on TGs
ADE: GI: the biggest is constipation abdominal fullness, diarrhea, can also increase the
risk of hyperchloremic metabolic acidosis in pts/w renal impairment.
