Final answer:
If a bandage-type pulse ox probe is applied overly tight to an infant’s finger, it is likely to result in skin irritation and bruising, along with potentially false low oxygen saturation readings due to reduced blood flow.
Step-by-step explanation:
When a bandage-type pulse ox probe is applied too tightly to an infant's finger, we can expect skin irritation and bruising (c) to occur. This is because excessive pressure can impair blood circulation to the area under the probe. While a secure fit is necessary to obtain accurate oxygen saturation measurements, a fit that is too tight can cause both discomfort and potential injury to the patient. Additionally, an overly tight probe can lead to false readings, typically a false low oxygen saturation reading, because the tightness may reduce blood flow, thereby affecting the measurement recorded by the pulse oximeter.
