If a patient with aspirin sensitivity is experiencing severe symptoms, which of the following may occur?

In cases where a patient with aspirin sensitivity experiences severe symptoms, shock and loss of consciousness can occur. Aspirin sensitivity, particularly in individuals with asthma or nasal polyps, can lead to severe respiratory reactions, including anaphylaxis in some instances. This systemic allergic reaction can manifest as a profound drop in blood pressure (shock) and can compromise the patient's airway, resulting in loss of consciousness. Recognizing that aspirin intolerance can precipitate serious symptoms is crucial for timely intervention.

Other options, while they might seem plausible in other contexts, do not typically present as severe or immediate consequences of aspirin sensitivity. For example, weight gain and increased appetite are not common reactions related to the acute effects of aspirin sensitivity. Similarly, headache and nausea can be associated symptoms but are not as severe as shock and loss of consciousness, thereby making the latter the most critical and concerning outcome in this scenario. Understanding these potential severe responses is essential for effective management and patient education regarding aspirin sensitivity.
