Correct Answer is C

Explanation

A) Toe. Thickened toenails and edema make this site unreliable for accurate readings.
B) Skin fold. Skin folds are not recommended for pulse oximetry measurements due to poor contact and inconsistent readings.
C) Earlobe. The earlobe is a preferred site in cases of peripheral edema or thickened nails because it has good perfusion and provides reliable readings.
D) Finger. Edema in the hands compromises the accuracy of finger pulse oximetry measurements.

A. A nonrebreather mask should fit snugly over a client's face. B. The reservoir bag on a nonrebreather mask should collapse with exhalation. C. A nonrebreather mask dries a client's mucous membranes. D. Use a non rebreather mask to deliver low-flow oxygen.

Correct Answer is A

Explanation

A) A nonrebreather mask should fit snugly over a client's face. A proper fit ensures effective oxygen delivery and prevents room air from entering the mask.
B) The reservoir bag on a nonrebreather mask should collapse with exhalation. The reservoir bag should not completely collapse. If it does, the oxygen flow may be inadequate.
C) A nonrebreather mask dries a client's mucous membranes. While high-flow oxygen delivery systems can dry mucous membranes, this is not specific to non rebreather masks.
D) Use a non rebreather mask to deliver low-flow oxygen. Non rebreather masks are designed to deliver high concentrations of oxygen (typically 60% to 100%).
