The nurse is preparing to administer digoxin (Lanoxin) to a client experiencing atrial fibrillation. Which of the following electrolyte imbalances would the nurse assess to reduce the incidence of toxicity with digoxin (Lanoxin)?
hypocalcemia
hypokalemia
hyperkalemia
hypernatremia
The Correct Answer is B
A. Hypocalcemia is not directly linked to digoxin toxicity; rather, it is more associated with calcium channel blockers.
B. Hypokalemia increases the risk of digoxin toxicity, as low potassium levels can enhance the effects of digoxin on the heart.
C. Hyperkalemia is not directly associated with toxicity; however, it can cause complications in patients taking digoxin.
D. Hypernatremia does not have a direct impact on digoxin toxicity; monitoring potassium levels is more critical.

Correct Answer is B
Explanation
A. Daily weight monitoring is not specifically required with doxazosin and is more relevant for medications that may cause fluid retention or significant weight changes.
B. First-dose hypotension is a common and significant side effect of doxazosin, and advising the patient to lie down after the first dose helps mitigate the risk of dizziness and falls.
C. Impaired taste is not a known side effect of doxazosin, making this statement inaccurate.
D. While potassium intake is important for overall health, doxazosin does not typically require dietary potassium adjustments.
Correct Answer is C
Explanation
A. Doxazosin is an alpha-1 blocker that can be used for hypertension but is not a first-line option.
B. Carvedilol is a beta-blocker used in heart failure and post-MI but is not the first choice for initial hypertension treatment.
C. Lisinopril, an ACE inhibitor, is widely recognized as a first-line treatment for hypertension due to its effectiveness and favorable side effect profile.
D. Clonidine is generally not considered a first-line treatment for hypertension due to potential side effects and the availability of more effective alternatives.
