Normal range for oxygen saturation via pulse oximeter is?

A.

80-100%

B.

93-100%

C.

90-100%

D.

95-100%

Answer and Explanation

The Correct Answer is D

A: An oxygen saturation range of 80-100% is incorrect. Saturation levels below 90% are considered low and may indicate hypoxemia, requiring medical attention.

B: An oxygen saturation range of 93-100% is generally acceptable, but the ideal range is slightly higher to ensure adequate oxygenation.

C: An oxygen saturation range of 90-100% includes levels that are borderline low. While 90% is often used as a threshold for concern, the optimal range is higher.

D: An oxygen saturation range of 95-100% is considered normal and indicates adequate oxygenation of the blood. This range ensures that tissues receive sufficient oxygen to function properly.

Correct Answer is B

Explanation

A: Continuous output from the stoma is expected in patients with an ileostomy. The stoma continuously produces waste, and this is a normal finding.

B: The presence of blood in the stool is an abnormal finding and should be reported immediately. It could indicate bleeding within the gastrointestinal tract, which requires prompt medical evaluation and intervention.

C: Malodorous stool is common with an ileostomy and is not typically a cause for immediate concern. However, if the odor is unusually strong or different, it may warrant further investigation.

D: Liquid consistency of stool is normal for an ileostomy, as the large intestine, which absorbs water, is bypassed. This is not an immediate concern unless there are other symptoms present.
