A nurse is caring for a client in the emergency department. The client exhibits signs of altered mental status and has a history of decreased fluid intake. The healthcare team is assessing the client's condition for potential underlying issues. Indicate whether the following nursing actions are anticipated or contraindicated.

The emergency management of this client presenting with altered mental status, hypotension, tachycardia, elevated lactate, leukocytosis, and signs of dehydration whose findings suggest hypovolemic shock or possible septic shock, both of which require rapid stabilization of circulation and treatment of the underlying cause. Priority interventions aim to restore perfusion, support blood pressure, and treat infection if present. Understanding when to give fluids, vasopressors, antibiotics, or avoid diuretics is essential in critical care nursing. Rationale: • Initiate vasopressor therapy to manage hypotension: Vasopressors are not first-line treatment when hypotension is due to hypovolemia, as in this client with dry mucous membranes, elevated BUN, and decreased oral intake. The priority is to restore intravascular volume with fluids first. Using vasopressors prematurely can worsen tissue perfusion by constricting vessels without correcting the underlying volume deficit. • Administer IV fluids to increase intravascular volume: The client shows clear signs of volume depletion, including hypotension, tachycardia, dry mucous membranes, elevated BUN, and altered mental status. IV fluids are the first-line intervention to restore circulating volume and improve perfusion. This helps correct hypotension and supports organ function. Fluid resuscitation is essential in suspected hypovolemic or septic shock. • Administer diuretics to reduce fluid overload: There is no evidence of fluid overload in this client; instead, the findings indicate dehydration and poor perfusion. Diuretics would further reduce circulating volume and worsen hypotension and shock. This could lead to decreased organ perfusion and increased risk of organ failure. Therefore, diuretics are unsafe and inappropriate in this scenario. • Provide antibiotics for suspected septic shock: The elevated WBC count, increased lactate level, altered mental status, and hypotension raise concern for possible sepsis. Early antibiotic administration is critical in suspected septic shock to control infection and prevent progression to multi-organ failure. Even while fluid resuscitation is ongoing, antibiotics should be initiated promptly if infection is suspected. This is a time-sensitive, life-saving intervention.
