A nurse is assisting with the care of a client who is receiving penicillin via intermittent IV bolus. Which of the following should the nurse recognize as a clinical manifestation of anaphylaxis?

Choice A reason: Blurred vision is not an expected side effect of digoxin, but a sign of digoxin toxicity, which requires immediate medical attention.

Choice B reason: This is the correct answer because digoxin can cause hypokalemia (low potassium levels), which increases the risk of digoxin toxicity. Therefore, clients taking digoxin need to have their potassium levels monitored regularly and consume foods rich in potassium.

Choice C reason: Antacids can interfere with the absorption of digoxin and reduce its effectiveness. Clients taking digoxin should avoid taking antacids within two hours of taking the medication.

Choice D reason: Weighing oneself every other day is not related to digoxin therapy, but to fluid balance. Clients with heart failure, who are often prescribed digoxin, need to monitor their weight daily and report any significant changes to their health care provider.

Choice A reason: Wiping the top of the feeding container with alcohol is not a priority action, as it is not essential for infection control or safety. The nurse should use a sterile technique when opening and handling the feeding container.

Choice B reason: Placing the head of the client's bed at a 30° angle or higher is a priority action, as it can prevent aspiration or regurgitation of the feeding solution into the lungs, which can cause pneumonia or respiratory distress.

Choice C reason: Rinsing the feeding bag with water once the feeding is complete is not a priority action, as it can be done after ensuring that the client has tolerated the feeding well and has no signs of complications.

Choice D reason: Documenting the client's response to the feeding is not a priority action, as it can be done after performing other interventions and assessments that are more urgent and important for the client's well-being.
