Question 17

The nurse instructs a client taking digoxin (Lanoxin) for treatment of congestive heart failure (CHF) to eat:

Accepted Answer

Potatoes are high in potassium, and potassium-rich foods should be encouraged to help prevent hypokalemia in clients taking digoxin.

Question 18

A nurse is preparing to administer nitroglycerin (NTG) via the sublingual route. The nurse knows that nitroglycerin tablets are administered sublingually to:

Accepted Answer

Sublingual medications are absorbed quickly into the bloodstream and are ready for action earlier than oral medications.
