Which laboratory analyses were sent to the lab as part of the resuscitation workup?

• A. Blood typing, arterial blood gases, and lactate levels
• B. Complete blood count, cholesterol, and glucose
• C. Blood typing, electrolyte panel, and bilirubin
• D. Coagulation profile, lactate, and kidney function

Answer: (A)

In resuscitation, you need data that you can act on right away to guide blood transfusion, ventilation, and tissue perfusion. The combination of blood typing, arterial blood gases, and lactate levels provides this directly: blood typing allows quickly issuing compatible blood if a transfusion is needed, arterial blood gases give real-time insight into oxygenation, ventilation, and acid–base status to fine-tune support, and lactate indicates how well tissues are being perfused and how the patient is responding to resuscitation. These pieces are the most immediately actionable in the acute flow of resuscitation. While other lab tests like CBC, lipid panel, bilirubin, or a broader coagulation/kidney assessment have value, they are not as urgently informative for guiding the initial resuscitative steps as the trio listed.
