Normal range for oxygen saturation via pulse oximeter is?

80-100%

93-100%

90-100%

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.

A. Hold the cane on the right side to provide support for the weaker leg B. Remove the rubber tip when using the cane. C. Advance the right leg and the cane together to support the weaker leg D. Place the cane approximately 61 cm (24 in) in front of her feet before advancing

Correct Answer is A

Explanation

A: The correct instruction is to hold the cane on the right side, which is the side opposite the weaker leg. This provides better support and balance for the weaker side.

B: Removing the rubber tip from the cane is not recommended. The rubber tip provides traction and stability, reducing the risk of slipping.

C: Advancing the right leg and the cane together is incorrect. The cane should move with the weaker leg (left leg in this case) to provide support during ambulation.

D: Placing the cane 61 cm (24 in) in front of the feet is too far. The cane should be placed about 15-25 cm (6-10 in) in front of the feet to provide optimal support and balance.
