1
Rationale 1: Heavy pressure to the probe should be avoided because it may impede blood flow—the probe should be placed gently against the client's skin, over the artery to be auscultated.
Rationale 2: A small amount of gel is applied to the end of the Doppler probe to eliminate interference.
Rationale 3: Informing the healthcare provider may be premature until it is determined that the Doppler probe is being used correctly.
Rationale 4: Sending the equipment for repair is premature at this time.
