A nurse is assisting with the care of a client who is receiving a continuous IV infusion. Which of the following findings indicates fluid volume overload?

A. Encourage visits from family members: While family presence can help reduce anxiety and reorient clients with delirium, it is not the immediate first step. Before implementing supportive strategies, the nurse must first assess the client’s neurological status to determine the severity and possible cause of the delirium.

B. Administer an anxiolytic medication: Administering medications should not be the first action because delirium can be caused by multiple reversible factors. Sedating a client without identifying the underlying cause may worsen confusion or mask important symptoms that need immediate intervention.

C. Determine the client's level of consciousness: Assessing the client’s level of consciousness is the priority because it provides critical information about the severity of the delirium and helps guide immediate and appropriate interventions. Early assessment ensures that life-threatening conditions, such as hypoxia or sepsis, are not overlooked.

D. Keep lights on in the client's room: Maintaining a well-lit environment can help prevent disorientation, especially at night, but it is a secondary supportive measure. Assessment of mental status must occur first to prioritize safety and identify urgent medical needs.

• Allergies: The client has a documented allergy to penicillin, and cefazolin is a first-generation cephalosporin. Cephalosporins have a similar beta-lactam structure to penicillins, and there is a potential risk of cross-reactivity. Administering cefazolin without provider clearance could result in a severe allergic reaction or anaphylaxis.
• Temperature: Although the client's temperature is elevated at 39.3° C (102.8° F), this is an expected finding in pneumonia and does not need to be reported before antibiotic administration. In fact, treating the infection may help reduce the fever.
• Chest x-ray: The chest x-ray showing left lower lobe density is consistent with a diagnosis of pneumonia and supports the need for antibiotic treatment. This finding confirms the infection in the lungs and guides the choice of antibiotic therapy. It is not a reason to withhold the prescribed medication but rather a justification for it.
• WBC count: The client’s WBC count is elevated at 16,000/mm³, which is typical in bacterial infections like pneumonia. It reflects the body's immune response and further supports the need for antibiotics rather than delaying them.
