The nurse attaches a pulse oximeter to a client’s finger and obtains an oxygen saturation reading of 91%. Which assessment finding most likely contributes to this reading?

Capillary refill time is 2 seconds.

2+ edema of fingers and hands.

Radial pulse volume is 3+.

Blood pressure is 142/88 mm Hg.

Answer and Explanation

The Correct Answer is B

Choice B rationale

2+ edema of fingers and hands. Edema can interfere with the accuracy of pulse oximetry readings by affecting the perfusion of the area where the sensor is placed. This can lead to falsely low oxygen saturation readings.

Choice A rationale

Capillary refill time is 2 seconds. A capillary refill time of 2 seconds is within normal limits and is unlikely to affect the accuracy of the pulse oximetry reading.

Choice C rationale

Radial pulse volume is 3+. A strong radial pulse indicates good peripheral perfusion, which should not negatively impact the accuracy of the pulse oximetry reading.

Choice D rationale

Blood pressure is 142/88 mm Hg. While elevated blood pressure can have various effects on the body, it is not likely to directly affect the accuracy of a pulse oximetry reading.

Correct Answer is A

Explanation

Choice A rationale

Beginning with questions that are less sensitive in nature helps build rapport and makes the client more comfortable. This approach gradually leads to more sensitive topics, reducing anxiety and promoting honest responses.

Choice B rationale

Getting the most difficult questions over with first can increase the client’s anxiety and discomfort, leading to less honest or incomplete answers. It is not an effective strategy for sensitive topics.

Choice C rationale

Sharing personal values to put the client at ease can introduce bias and affect the client’s responses. It is important to remain neutral and nonjudgmental.

Choice D rationale

Asking questions in a vague, non-specific format can lead to misunderstandings and incomplete information. Clear, direct questions are more effective for gathering accurate information.

A. Tests for a gag reflex before performing oral care. B. Places the client in a supine position. C. Suctions secretions from the posterior pharynx. D. Uses an oral airway to keep the teeth apart.

Correct Answer is B

Explanation

Choice A rationale

Testing for a gag reflex before performing oral care is a standard practice to ensure the client’s safety and prevent aspiration. This action does not indicate a need for additional training.

Choice B rationale

Placing the client in a supine position is incorrect and indicates a need for additional training. The correct position for performing oral care on an unconscious client is a side-lying position to prevent aspiration and ensure secretions can drain from the mouth.

Choice C rationale

Suctioning secretions from the posterior pharynx is a necessary action to maintain airway patency and prevent aspiration. This action does not indicate a need for additional training.

Choice D rationale

Using an oral airway to keep the teeth apart is a standard practice to facilitate oral care and prevent the client from biting down on the caregiver’s fingers or equipment. This action does not indicate a need for additional training.
