Correct Answer is B

Explanation

Choice A reason: While the Fowler's position can aid in breathing, it is not the first action to take if the oxygen saturation monitor is reading low.

Choice B reason: Ensuring the proper placement of the sensor probe is the first step, as incorrect placement can lead to inaccurate readings.

Choice C reason: Increasing the oxygen flow rate should only be considered after confirming the accuracy of the oxygen saturation reading.

Choice D reason: Encouraging deep breaths may be helpful, but it is not the first action to take. The priority is to ensure the oxygen saturation reading is accurate.
