A client being treated with desmopressin exhibits confusion and drowsiness. What is the nurse's best action?

In this situation, the best action is to take the client's vital signs. Monitoring vital signs is a critical first step in assessing the patient’s condition and understanding the potential severity of their symptoms. Confusion and drowsiness can indicate various underlying issues, such as electrolyte imbalances, changes in blood pressure, or abnormal heart rates. By obtaining vital signs, the nurse can gather essential information that may guide further interventions.

For example, if the vital signs indicate hypotension or tachycardia, it may suggest a need for urgent intervention or a change in treatment. Conversely, stable vital signs might help determine that the confusion and drowsiness are related to the medication or another manageable cause.

While increasing fluid intake may seem like a reasonable action considering desmopressin's role in managing conditions related to fluid balance, it is not the most immediate step without first evaluating the patient's current hemodynamic status through vital signs. Administering a pain reliever may not address the underlying issues causing the confusion and drowsiness. Contacting the physician should also follow after the preliminary assessment is completed, as providing vital signs will assist in conveying critical information to the healthcare team.
