Registered Psychiatric Nurses of Canada Examination (RPNCE) Practice Test

The most appropriate first step when Mrs. Sparrow develops a rash after taking amoxicillin is to stop the medication. This action is crucial because a rash can be an indication of an allergic reaction or sensitivity to the medication, particularly with penicillin derivatives like amoxicillin. Discontinuing the medication promptly minimizes the risk of escalation to more severe reactions, such as anaphylaxis.

Assessing the situation by halting the potentially offending drug is a standard practice in nursing care to ensure patient safety. While contacting the physician may also be an important follow-up, the immediate action of stopping the medication takes precedence in safeguarding the patient’s health. This step ensures that no further exposure occurs while the situation is evaluated.

Appropriately handling any subsequent symptoms, such as administering an antihistamine or applying cool compresses, can be done after the initial and most critical step of discontinuation.
