Shortly after providing a new sleeping pill to a patient on the medical unit, the nurse answers the patient's call light. Which of the following findings would indicate to the nurse that the patient is experiencing an anaphylactic reaction to the medication?

A. The patient complains of shortness of breath: Shortness of breath is a hallmark symptom of an anaphylactic reaction. It indicates that the patient may be experiencing airway constriction, which is a medical emergency. B. The patient reports feeling hot, and her face appears flushed: Flushing and a feeling of warmth can be early signs of an allergic reaction, but they are not specific to anaphylaxis. Other more severe symptoms would need to be present to diagnose anaphylaxis. C. The patient states that she feels nauseated and has a headache: Nausea and headache are not typically associated with anaphylaxis. They may be side effects of the medication but are not indicative of an allergic reaction severe enough to cause anaphylaxis. D. The patient complains of continued wakefulness and agitation: Continued wakefulness and agitation could be side effects of the sleeping pill but are not symptoms of an anaphylactic reaction. These symptoms do not require immediate emergency intervention like anaphylaxis would.
