Correct Answer is C

Explanation

The operating room is a sterile environment, and it is critical to maintain a clean and controlled environment to reduce the risk of infection to the patient. The measures taken include maintaining positive air pressure, controlling temperature and humidity, filtering the air, using sterile surgical instruments, and limiting traffic in and out of the operating room. These measures help to prevent the spread of infectious agents that may be present in the operating room. While the other options (a, b, and d) may also be important considerations in the design of the operating room, preventing transmission of infection is the primary goal.

A. 5.0 mEq/L B. 2.9 mEq/L C. 3.8 mEq/L D. 6.0 mEq/L

Correct Answer is B

Explanation

Furosemide is a loop diuretic that works by blocking the reabsorption of sodium and chloride in the ascending loop of Henle in the kidney, leading to increased urine output. However, this medication can also cause potassium loss through increased urinary excretion, which can lead to hypokalemia (low potassium level). Hypokalemia can cause confusion, weakness, and other neurological symptoms.

The normal range for serum potassium is 3.5 to 5.0 mEq/L. A potassium level of 2.9 mEq/L is below the normal range and is considered hypokalemic. Therefore, the nurse should correlate the client's confusion with the low potassium level and notify the healthcare provider to adjust the medication or provide potassium supplements if indicated.
