Which data should the nurse assess for the client with a seizure disorder who is taking valproate (Depakote)?

Choice A rationale

While obtaining the client's heart rate is important for a complete assessment, it is not the immediate priority in managing autonomic dysreflexia. Bradycardia often accompanies the hypertension, but addressing the physiological trigger and reducing the severe blood pressure elevation is more critical to prevent life-threatening complications.

Choice B rationale

Assessing the client for bladder distention is crucial, as it is a common precipitating factor for autonomic dysreflexia. However, the initial action should focus on rapidly reducing the dangerously high blood pressure to prevent complications like stroke, which can be achieved through immediate positional changes.

Choice C rationale

Administering a nitrate antihypertensive is a pharmacological intervention that might be necessary, but it is not the first action. The immediate priority is to non-pharmacologically reduce the blood pressure and search for the underlying noxious stimulus. Pharmacological agents are used if initial measures are insufficient.

Choice D rationale

Placing the client in a high-Fowler's position is the most immediate and critical first action. This position helps to reduce blood pressure by promoting venous pooling in the lower extremities, thereby decreasing venous return to the heart and reducing cerebral blood flow, mitigating the risk of intracranial hemorrhage from severe hypertension.

Choice A rationale

Alendronate, a bisphosphonate, requires the client to remain upright for at least 30 minutes to facilitate gravitational transport of the medication through the esophagus and minimize esophageal irritation. This upright position helps prevent reflux and subsequent erosive esophagitis, a common adverse effect associated with delayed esophageal clearance and prolonged contact of the medication with the esophageal mucosa, ensuring safe drug delivery.

Choice B rationale

Taking alendronate with food significantly decreases its bioavailability due to chelation with various ions found in food, such as calcium and magnesium. This interaction forms insoluble complexes, reducing drug absorption from the gastrointestinal tract and consequently diminishing the therapeutic efficacy of the medication in inhibiting osteoclast activity and bone resorption.

Choice C rationale

Orange juice, being acidic, can further increase the risk of esophageal irritation when taken with alendronate. Furthermore, calcium fortified orange juice can bind to the medication, reducing its absorption. The acidic pH might also contribute to the degradation of the drug before it can be adequately absorbed, compromising its therapeutic effect on bone density.

Choice D rationale

Alendronate effervescent tablets are designed to be dissolved in water and swallowed as a solution. Chewing or sucking on the tablet can cause direct irritation to the oral mucosa and pharynx, leading to local tissue damage. This method also bypasses the intended rapid dissolution in water, potentially affecting proper absorption and increasing the risk of adverse gastrointestinal effects.
