Exhibits What order by the health care provider should the nurse question?

A. Increase 0.9% Normal Saline infusion to 250 mL/hr per protocol: The client is hypotensive (BP 90/62 mmHg), tachycardic (HR 120 bpm), has low CVP (1 mmHg) and PAWP (2 mmHg), and shows signs of hypovolemia such as decreased skin turgor and dry mucous membranes. Administering isotonic saline to expand intravascular volume is appropriate to improve perfusion and hemodynamics. B. Administer Furosemide (Lasix) 20 mg IV push: Furosemide is a loop diuretic that promotes fluid and sodium excretion. Given the client’s hypovolemic state, hypotension, low CVP, and hypernatremia (Na+ 149 mEq/L), administering furosemide could further deplete intravascular volume, worsen hypotension, impair renal perfusion, and exacerbate electrolyte imbalances. C. Collect UA for culture and sensitivity: The client has fever (101°F) and leukocytosis (WBC 12,000/mm³), suggesting a possible urinary tract infection. Collecting a urine sample for culture is appropriate for identifying the pathogen and guiding targeted antimicrobial therapy, making this order medically sound. D. Collect blood cultures and start Vancomycin 1 gm IV: Signs of systemic infection (fever, tachycardia, confusion, hypotension) raise concern for sepsis. Obtaining blood cultures and starting empiric broad-spectrum antibiotics such as Vancomycin is indicated to manage potential bacteremia or sepsis, aligning with evidence-based infection control protocols.
