The practical nurse (PN) is caring for a client with costochondritis who is now experiencing increased discomfort in breathing. The client receives a prescription for meloxicam. Which intervention should the PN include in the client’s POC?

Choice A reason: Taking medications with food may reduce gastric irritation but does not prevent anaphylactic reactions to penicillin, which are immune-mediated. This advice is irrelevant for avoiding future allergic responses, as it does not address the systemic hypersensitivity triggered by penicillin exposure.

Choice B reason: A medic alert bracelet is critical for a client with a penicillin anaphylaxis history, as it alerts healthcare providers to avoid penicillin, preventing potentially fatal allergic reactions. Anaphylaxis involves IgE-mediated histamine release, and re-exposure risks rapid, life-threatening symptoms, making this the most important instruction.

Choice C reason: Keeping epinephrine is useful for managing anaphylaxis but is secondary to prevention. A medic alert bracelet proactively avoids penicillin exposure, reducing the need for emergency intervention. Epinephrine treats symptoms but does not address the root cause of re-exposure risk.

Choice D reason: Taking all prescribed ampicillin is dangerous, as the client had an anaphylactic reaction, indicating a severe allergy. Continuing the drug risks recurrent, potentially fatal reactions. This choice is incorrect, as it contradicts the need to avoid the allergen entirely.

Choice A reason: Gum appearance is unrelated to carbamazepine’s side effects or sore throat. While some antiseizure drugs cause gingival hyperplasia, carbamazepine does not, and gum assessment does not clarify the sore throat’s cause, which may indicate infection or agranulocytosis, making this choice irrelevant.

Choice B reason: Bowel sounds assess gastrointestinal function, not relevant to a sore throat or carbamazepine’s effects. Sore throat may signal agranulocytosis, a rare side effect, but bowel sounds do not provide data on infection or hematologic issues, making this choice inappropriate.

Choice C reason: Carotid pulse volume evaluates cardiovascular status but is unrelated to sore throat or carbamazepine’s side effects. Sore throat may indicate infection or agranulocytosis, requiring systemic assessment like temperature, not vascular checks, making this choice irrelevant for the reported symptom.

Choice D reason: Temperature is critical, as sore throat may indicate infection or agranulocytosis, a rare but serious carbamazepine side effect causing low white blood cells. Fever suggests infection, necessitating urgent reporting. This assessment provides key data to differentiate causes, guiding timely intervention.
