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 B
Explanation
A. Hypokalemia is not a common side effect of alteplase; instead, it may result from other factors.
B. Internal bleeding is a significant risk associated with thrombolytics like alteplase, as they promote the breakdown of clots but can also affect hemostasis.
C. Pancytopenia is not directly associated with alteplase use; it may occur with other medications or conditions.
D. Hypertension is not a common side effect of alteplase; instead, blood pressure may fluctuate but is not typically increased as a direct result of the medication.
