Maintain the affected extremity in a dependent position.

Palpate the dorsalis pedis pulse.

Wrap sterile gauze on the sharp point of the pins.

Adjust the clamps on the fixator frame.

Answer and Explanation

The Correct Answer is B

Palpating the dorsalis pedis pulse is an essential action to monitor for adequate circulation and perfusion in an extremity with an external fixator, which is a device that stabilizes and aligns fractured bones with metal pins and rods outside of the skin. The other options are incorrect because they could cause complications such as edema, infection, or malalignment.

Correct Answer is A

Explanation

A high white blood cell (WBC) count is a common sign of infection and inflammation, such as pneumonia. The normal range of WBC count is 4,500 to 11,000/mm3 . Sodium, blood urea nitrogen (BUN), and hematocrit are not directly related to pneumonia and may vary depending on other factors such as hydration status, renal function, and blood loss.
