A Cardiovascular nurse is preparing to measure a client's level of oxygen saturation and observes edema of both hands and thickened toenails. The nurse should apply the pulse oximeter probe to which of the following locations?
Toe.
Earlobe.
Skin fold.
Finger.
The Correct Answer is B
Choice A rationale:
Applying the pulse oximeter probe to the toe is not the most appropriate location. While toe measurements can be used, the fingers are more commonly used due to their accessibility and accuracy. Edema in the hands could affect the accuracy of readings.
Choice B rationale:
The nurse should apply the pulse oximeter probe to the earlobe. This choice is correct because the earlobe is a well-vascularized and easily accessible area that provides accurate oxygen saturation measurements. Thickened toenails and edema of the hands might compromise readings in those locations.
Choice C rationale:
Applying the pulse oximeter probe to a skin fold is not a recommended site for oxygen saturation measurement. While there are various sites where pulse oximeters can be applied, the earlobe and finger are more suitable due to their consistent blood flow and accessibility.
Choice D rationale:
While applying the pulse oximeter probe to the finger is a common and acceptable practice, in this scenario, edema of the hands could affect the accuracy of the readings. The earlobe is a better choice as it is less likely to be affected by edema and can provide accurate readings.

Correct Answer is B
Explanation
Choice A rationale:
Stage I Pressure ulcer - This choice is not correct because a Stage I pressure ulcer is characterized by intact skin with non-blanchable redness over a bony prominence. There is no partial-thickness skin loss at this stage.
Choice B rationale:
Stage II Pressure ulcer - This is the correct choice. A Stage II pressure ulcer involves partial-thickness skin loss that presents as a shallow open ulcer with a red-pink wound bed, without slough. It may also manifest as an intact or open/ruptured serum-filled blister.
Choice C rationale:
Stage IV Pressure ulcer - This choice is not correct because a Stage IV pressure ulcer involves full-thickness tissue loss with exposed bone, tendon, or muscle. There is no mention of such extensive tissue loss in the given scenario.
Choice D rationale:
Stage II Pressure ulcer - This choice is a duplicate of Choice B and is not correct for the reasons stated above.
Correct Answer is B
Explanation
Choice A rationale:
Placing the cuff bladder over the client's brachial artery is a correct action when obtaining a blood pressure reading. This choice demonstrates proper cuff placement, which is essential for an accurate measurement.
Choice B rationale:
Placing the client's arm above the level of the client's heart is an incorrect action when obtaining a blood pressure reading. The client's arm should be supported at heart level to ensure accurate measurement. This choice indicates a need for further instruction as it could lead to an artificially low blood pressure reading.
Choice C rationale:
Wrapping the blood pressure cuff snugly around the client's arm is a correct action when obtaining a blood pressure reading. This choice demonstrates proper cuff application, which is necessary for accurate results.
Choice D rationale:
Checking the instrument gauge to ensure the reading starts at zero is a correct action when obtaining a blood pressure reading. This choice reflects a proper step to verify that the equipment is calibrated correctly.
