Pharmacology Hesi 2023 QUESTIONS AND
VERIFIED ANSWERS
Digoxin (Lanoxin) - positive inotrope (increases force of contraction); negative
chronotrope (decreases heart rate). How do you assess for this? - ANSWER-Always
take apical pulse for one full minute
Client with a long hx of daily digoxin and fourosemide (Lasix) use; creates a high
risk for dig toxicity because - ANSWER-Lasix can cause hypokalemia, which can
lead to dig toxicity
What can happen when Digoxin is taken with Dronedarone (Multaq), which is
another anti-dysrhythmic drug)? - ANSWER-Digoxin can increase in the blood level
and further increase the effects
What is the normal digoxin level? - ANSWER-0.5-2 ng/mL
Normal serum potassium level is - ANSWER-3.5-5.0 mEq/L
Low potassium or magnesium levels may increase risk for - ANSWER-Digoxin
toxicity
What are the signs and symptoms for digoxin toxcitiy? - ANSWER-anorexia,
bradycardia, headache, dizziness, confusion, nausea, and visual disturbances such
as blurred, yellow, or halo vision.
, When should you hold off on giving digoxin drug therapy? - ANSWER-if apical
pulse is less than 60
What effects do Calcium channel blockers (-dipine; amlodipine (Norvasc),
nifedipine (Procardia) cause - ANSWER-produce vasodialation and reflex
tachycardia
(lowers BP but increases HR)
Verapamil and diltiazam produce - ANSWER-vasodialation and cardiosuppresssion
(lowers BP and Lowers heart rate)
Beta blockers have the drug ending - ANSWER--OLOL such as atenolol, propanolol,
esmolol, ect.)
Beta 1 blocks receptors in the - ANSWER-heart
Beta 2 blocks receptors in the - ANSWER-lungs
