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 D

Explanation

A: Assessing the characteristics of the sputum is important for understanding the nature of the infection and the effectiveness of the treatment, but it is not the first action to take before the procedure.

B: Assessing pulse and respirations is the first action the nurse should take. This provides baseline data on the client’s respiratory and cardiovascular status, which is crucial for monitoring the client’s response to the procedure and ensuring safety.

C: Instructing the client to slowly exhale with pursed lips is a technique used to improve breathing efficiency and oxygenation, but it is not the first action to take before the procedure.

D: Auscultating lung fields is important for assessing the client’s respiratory status and identifying areas of congestion or decreased breath sounds, but it should follow the initial assessment of pulse and respirations.

A. Hypoglycemia B. Hypertension C. Hypervolemia D. Hypokalemia

Correct Answer is D

Explanation

A: Hypoglycemia is not a common adverse effect of Furosemide. This diuretic primarily affects fluid and electrolyte balance rather than blood glucose levels.

B: Hypertension is not an adverse effect of Furosemide. In fact, Furosemide is often used to treat hypertension by reducing fluid volume and lowering blood pressure.

C: Hypervolemia, or fluid overload, is not an adverse effect of Furosemide. This medication is a diuretic, which means it helps remove excess fluid from the body, thereby reducing hypervolemia.

D: Hypokalemia, or low potassium levels, is a common adverse effect of Furosemide. This diuretic can cause the body to lose potassium through urine, leading to potentially dangerous low levels of this essential electrolyte.
