Patient Data Exhibits Which laboratory tests would be helpful in determining the plan of care for this client? Select all that apply.

A. Electrolytes: Important for assessing fluid and electrolyte balance in a trauma patient receiving IV fluids and sedation. Abnormalities can affect cardiac, renal, and neuromuscular function and guide adjustments in therapy. B. Coagulation studies: Essential to evaluate for coagulopathy, which is common in trauma due to bleeding and hypothermia. Results help guide the use of plasma, platelets, or reversal agents. C. Lipid panel: Not relevant in the acute trauma setting. It is used for chronic cardiovascular risk assessment and does not contribute to immediate treatment decisions. D. Blood culture: Used to detect bloodstream infections, which are not suspected in this trauma case. There are no signs of fever or sepsis to justify this test at this time. E. Type and screen: Critical to prepare for potential blood transfusion. This client has internal bleeding and hypotension, so knowing blood type ensures rapid and compatible product administration. F. Urine osmolality: Not useful in trauma evaluation. It is typically used in assessing renal function in cases of fluid balance disorders, not acute hypovolemia or bleeding. G. Complete blood count: Necessary to evaluate hemoglobin and hematocrit for blood loss, as well as platelet count for bleeding risk. Guides transfusion decisions and monitors ongoing blood loss. H. Arterial blood gas: Helpful in assessing acid-base balance and oxygenation. In trauma, it detects hypoxia, shock, or metabolic acidosis and supports ventilator and perfusion management.
