A nurse is completing an incident report regarding a medication error. Which of the following team members should the nurse report the incident to first?

Hydroxyzine is a first-generation antihistaminethat crosses the blood-brain barrier, leading to significant anticholinergicand sedative effects. In contrast, hydralazine is a peripheral vasodilatorused for hypertension. This look-alike, sound-alike error involves switching a sedative for an antihypertensive, requiring close neurological and cardiovascular monitoring.

Rationale:

A.Sedation is a primary adverse effect of hydroxyzine due to its ability to block H1 receptors in the central nervous system. Because the client received this instead of a blood pressure medication, the nurse must monitor for extreme drowsiness, dizziness, and a possible risk for falls. Sedation is the most immediate and expected neurological consequence of this specific medication error.

B.Drooling is not associated with hydroxyzine; rather, this medication has anticholinergic properties that typically cause dry mouth (xerostomia). Hydroxyzine reduces secretions and blocks parasympathetic activity, making drooling an unlikely finding. If the client experiences drooling, the nurse should investigate other causes, such as neurological impairment or the effect of different pharmacological agents.

C.Diarrhea is not a common side effect of hydroxyzine administration. Antihistamines with anticholinergic effects are more likely to cause constipation due to slowed gastrointestinal motility. The nurse should monitor for decreased bowel sounds rather than increased frequency of stools. Diarrhea would be an atypical response to the mistaken administration of an antihistamine.

D.While hydralazine (the intended drug) treats hypertension, the nurse should monitor for high blood pressure because the client missedtheir antihypertensive dose. However, the prompt asks for the adverse effect of the medication actually given. Hydroxyzine itself does not cause hypertension; instead, the primary risk of the drug actually administered is central nervous system depression and potential hypotension.

Topiramate is a broad-spectrum anticonvulsantused for seizure control and migraine prophylaxis. It modulates voltage-gated sodium channels and enhances GABAergictransmission. For patients with dysphagia, the "sprinkle" formulation allows for oral administration without requiring the client to swallow a whole, large capsule shell.

Rationale:

A.Mixing the contents to be taken over several hours is incorrect because the entire dose must be consumed immediately to ensure therapeutic serum levels. Delayed consumption can lead to subtherapeutic dosing and an increased risk of breakthrough seizures. The nurse must supervise the administration to confirm that the full 25 mg dose is ingested in a single sitting.

B.Mixing the contents of the capsule in a spoonful of soft food, such as applesauce or pudding, is the recommended method for clients with difficulty swallowing. This technique ensures the medication is safely transported past the oropharynx without the risk of aspiration or choking. It is important that the food is not chewed, as the medication particles have a bitter taste.

C.Placing the contents on the tongue to dissolve is inappropriate for topiramate capsules. The medication is not formulated as an orally disintegrating tablet (ODT) and will not dissolve efficiently in the mouth. Furthermore, the taste of the undiluted medication is highly unpleasant and can cause mucosal irritation, leading to poor patient compliance and distress during administration.

D.Chewing the capsule or its contents is contraindicated because it can destroy the intended release profile and cause an immediate, unpleasant taste. Topiramate particles should be swallowed whole to avoid irritation of the mouth and throat. Chewing also increases the risk of the medication getting stuck in dental crevices, preventing the full dose from reaching the stomach for absorption.
