Answer:
O An extremity with slow cap refill time
Explanation:
Intraosseous access can be used in patients, children inclusive, to gain vascular access when they are in shock due to sickness or injury. IO cannulation rapidly delivers drugs and fluid to a marrow venous plexus that is noncollapsible. This is especially important if the patient is in shock and is to be resuscitated fast. Slow or prolonged capillary refill time is an indication of shock.
This option is used when other measures of delivering drugs, for example, the intravenous route are unavailable. The distal femur, the proximal tibia under the growth plate, the distal tibia above the medial malleolus are common sites where intraosseous access can be administered.
