Before initiating treatment with amitriptyline (Elavil), what should the nurse assess in the client?

Before initiating treatment with amitriptyline, assessing the client's vital signs is crucial for several reasons. Amitriptyline is a tricyclic antidepressant that can influence cardiovascular parameters, including heart rate and blood pressure. It has the potential to cause side effects such as orthostatic hypotension, tachycardia, and other cardiovascular disturbances, which can be significant in a client with preexisting conditions.

Monitoring vital signs helps the nurse establish a baseline to identify any potential adverse effects once treatment begins. Additionally, understanding the client's blood pressure and heart rate can guide the clinician in evaluating the safety of prescribing this medication and allow for timely interventions if any concerning changes occur during treatment. By prioritizing the assessment of vital signs, the nurse ensures the client's safety and well-being throughout the treatment process with amitriptyline.

The other options, while relevant in different contexts, do not address the immediate physiological considerations associated with starting this specific medication.
