Final answer:
Coarse crackles in the lungs
Step-by-step explanation:
The correct answer is: 1) Coarse crackles in the lungs
When a patient's pelvis is unstable and they are experiencing signs of shock, the use of a pneumatic antishock garment (PASG) can help stabilize their condition. However, if further assessment reveals coarse crackles in the lungs, it suggests the presence of pulmonary edema or fluid in the lungs. In this case, the PASG would be contraindicated because it can further compromise breathing and oxygenation.
