Question 1 of 5
A client diagnosed with strep throat requires antibiotics for treatment. With an allergy to penicillin, the nurse understands which medication should be avoided due to cross-sensitivity with penicillin medications?

Question 2 of 5
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?
Correct Answer: B
Rationale: Hypokalemia, or low potassium levels, significantly increases the risk of digoxin toxicity. Potassium and digoxin compete for binding at the same sites in the heart, and low potassium levels enhance digoxin's effects, potentially leading to toxicity.

Rationale: NSAIDs (nonsteroidal anti-inflammatory drugs) can be used to reduce the flushing associated with niacin. Flushing is a common side effect of niacin due to the dilation of blood vessels.
