Problem 9

Which findings from M.G.'s assessment would indicate an increased possibility of digoxin toxicity? Explain your answer.
a. Serum potassium level of $2.2 \mathrm{mEq} / \mathrm{L}$
b. Serum sodium level of $139 \mathrm{mEq} / \mathrm{L}$

Problem 11

M.G.'s symptoms improve with IV diuretics and the digoxin. She is placed back on oral furosemide (Lasix) once her weight loss is deemed adequate to achieve a euvolemic state. What will determine whether the oral dose will be adequate to consider her for discharge?
