What assessment finding would indicate the need for a pneumatic anti-shock garment in a patient in shock?

The presence of pelvic instability combined with a blood pressure of 78/48 mmHg is a significant indicator that a patient is in shock and may benefit from the use of a pneumatic anti-shock garment (PASG). This garment is designed to provide mechanical support by compressing the lower body and promoting blood flow to vital organs during a state of shock, particularly in cases of hypovolemic or hemorrhagic shock.

In this scenario, the low blood pressure reflects a critical state where the body is struggling to maintain adequate perfusion to vital organs. Pelvic instability often indicates a potentially significant blood loss due to trauma, which can exacerbate the shock state. By employing a pneumatic anti-shock garment, the pressure can help stabilize the pelvis, control bleeding, and improve hemodynamic status while awaiting further medical intervention.

Other stated choices do not present assessments that convincingly suggest a need for this type of intervention. An increased heart rate with a normal blood pressure indicates compensatory mechanisms at play without significant signs of shock. Normal respiratory rate coupled with strong pulses suggests adequate perfusion and stability. Mild confusion with low blood sugar signifies a metabolic issue rather than shock, where immediate oral glucose might be more appropriate than a mechanical device like a PASG.
