Vitamin C can be found in which of the following sources?

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.

A. "Break the lozenge in half, making it easier to swallow."
Breaking the lozenge in half may reduce the effectiveness by altering how the medication is released and absorbed. Lozenge medications are designed to dissolve slowly.

B. "Take the lozenge with a glass of milk."
Milk could coat the mouth and throat, potentially reducing the absorption of the medication and decreasing its effectiveness.

C. "Swallow the medication with a drink of water."
Swallowing the lozenge whole would bypass the intended local effect in the mouth and throat, reducing the medication’s effectiveness in treating a sore throat.

D. "Suck on the lozenge until it dissolves." Sucking on the lozenge until it dissolves allows the medication to be released slowly and absorbed directly into the tissues of the mouth and throat, where it can have the most therapeutic effect.
