LPN ATI Fundamental Exam | Nurselytic

Correct Answer: C

Rationale: Select an alternate site to place the oximetry probe if the capillary refill is less than 2 seconds: Capillary refill time is not directly related to the placement of the pulse oximetry probe. Capillary refill is assessed to evaluate peripheral perfusion. Use an adhesive oximetry probe for a client who has a latex allergy: The type of probe used for pulse oximetry is important, especially for clients with latex allergies. However, the correct action is to use a nonlatex probe or a probe that is compatible with the client’s allergy, not necessarily an adhesive probe. Remove polish from the client’s fingernail before applying the oximetry probe: Correct. Nail polish can interfere with the accuracy of pulse oximetry readings, as it may affect light transmission through the nail bed. It is essential to remove nail polish or artificial nails before applying the probe. Lubricate the tip of the oximetry probe: Lubricating the tip of the oximetry probe is not necessary for proper use and may interfere with the accuracy of readings.
