When assessing a client's oxygen saturation reading, the nurse realizes that what will affect this reading?

1. Activity
2. Environmental conditions
3. Nutrition
4. Skin color

Question 2

In the palpatory method of blood pressure determination, instead of listening for the blood flow sounds, light to moderate pressure is used over the artery as the pressure in the cuff is released.

When will the nurse read the pressure from the sphygmomanometer?
1. When the cuff is applied
2. When the cuff is being deflated
3. When the first pulsation is felt
4. When the second pulsation is felt

Answer to Question 1

Correct Answer: 1
Rationale 1: Factors affecting oxygen saturation readings are hemoglobin, circulation, and activity. If there is shivering or excessive movement of the sensor site, this will interfere with an accurate reading.
Rationale 2: Environmental conditions do not affect an accurate oxygen saturation reading.
Rationale 3: Nutrition does not affect an oxygen saturation reading.
Rationale 4: Skin color does not affect an oxygen saturation reading.

Answer to Question 2

Correct Answer: 3
Rationale 1: Assessing the pulse before the cuff is inflated is not the pressure.
Rationale 2: This is not the client's blood pressure if the cuff is just being deflated.
Rationale 3: The first pulsation that is felt after the cuff is slowly deflated is the blood pressure reading that is recorded if the palpatory method is used to assess a client's blood pressure.
Rationale 4: If the second pulsation is recorded, that would be an inaccurate reading.
