Why is it necessary to stop the infusion immediately in case of a hypersensitivity reaction?

Stopping the infusion immediately in the event of a hypersensitivity reaction is critical to prevent further exacerbation of the patient's condition and to allow for prompt intervention. Hypersensitivity reactions can range from mild symptoms such as itching and rash to severe anaphylactic reactions, which can be life-threatening. By halting the infusion right away, healthcare providers minimize the body's exposure to the offending agent, allowing for the administration of appropriate treatments such as antihistamines, corticosteroids, or epinephrine. Immediate intervention can significantly improve patient outcomes by managing symptoms before they escalate.

The other choices do not address the urgency and clinical necessity of stopping the infusion in a medical emergency. Minimizing costs does not take precedence over patient safety. Maintaining the integrity of the treatment and ensuring compliance with healthcare regulations, while important, are secondary to the patient’s immediate health needs in cases of hypersensitivity reactions.
