Which of the following complications is associated with the administration of radiopharmaceuticals?

The administration of radiopharmaceuticals can lead to various complications, with allergic reactions being one of the more recognized risks. Allergic reactions may occur due to hypersensitivity to components within the radiopharmaceutical, which can include the carrier substance, preservatives, or even the radiolabel itself. Symptoms of an allergic reaction can range from mild reactions, such as rashes or itching, to more severe anaphylactic reactions, which are rare but can be life-threatening.

In the context of nuclear medicine, healthcare professionals are trained to monitor patients for any signs of an allergic response, especially in individuals with a known history of allergies. Awareness and preparedness are essential in managing these potential complications effectively.

While other complications like cardiac arrest, sepsis, and hemorrhage can occur in a clinical setting, they are generally less directly associated specifically with the administration of radiopharmaceuticals compared to allergic reactions. This distinction makes allergic reaction the most relevant choice in this context.
