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.

Correct Answer is C

Explanation

A: Calling the prescribing physician is important, but the immediate action should be to withhold the medication to prevent further elevation of potassium levels.

B: Calling the lab to verify the results can be done, but the immediate action should be to withhold the medication.

C: Omitting the KCL dose and documenting it is the correct action. The client’s potassium level is already elevated, and administering additional potassium could be harmful.

D: Giving the ordered KCL as prescribed is not appropriate because the client’s potassium level is already above the normal range.

A. Expect some swelling in the hands and feet. B. Take the medication at bedtime. C. Eat foods that contain plenty of potassium. D. Take aspirin if headaches develop.

Correct Answer is C

Explanation

A: Expecting some swelling in the hands and feet is incorrect. Furosemide is a diuretic used to reduce fluid buildup, so swelling should decrease, not increase.
B: Taking the medication at bedtime is not recommended because furosemide increases urine output, which can disrupt sleep. It is better to take it in the morning.
C: Eating foods that contain plenty of potassium is important because furosemide can cause potassium loss. Consuming potassium-rich foods helps maintain electrolyte balance and prevent hypokalemia.
D: Taking aspirin if headaches develop is not related to the use of furosemide. The nurse should address headache management separately and ensure the client understands the specific instructions for furosemide use.
