Normal range for oxygen saturation via pulse oximeter is?
80-100%
93-100%
90-100%
95-100%
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 D
Explanation
A: Pain at the incision site is expected after surgery and does not necessarily indicate a complication. It is important to assess the level and nature of the pain, but pain alone is not a definitive sign of a wound healing complication.
B: Itching at the incision site can be a normal part of the healing process as the wound closes and new tissue forms. While it can be uncomfortable, it is not typically a sign of a complication.
C: An approximated incision means the edges of the wound are close together and healing well. This is a positive sign and indicates that the wound is healing properly.
D: A mass, bluish in color at the incision site, may indicate a hematoma or infection, both of which are complications of wound healing. This finding requires immediate medical attention to address the underlying issue.
