After applying pneumatic compression devices to bilateral lower extremities on a patient who is on bedrest, the patient asks what the purpose is of the device. How should the nurse respond to best address the patient's question?

"These help to get rid of clots that are in your legs that can cause problems."

"These help circulate air and provide compression to your legs."

"These will help you to perform passive range of motion to your legs."

"These will help to reduce the risk of developing a venous thrombus."

Answer and Explanation

The Correct Answer is D

A. "These help to get rid of clots that are in your legs that can cause problems." Pneumatic compression devices prevent clots; they do not treat existing ones.

B. "These help circulate air and provide compression to your legs." While compression is correct, the reference to circulating air is misleading, as the device improves blood circulation, not air movement.

C. "These will help you to perform passive range of motion to your legs." Pneumatic compression devices do not move the legs; they promote circulation through intermittent pressure.

D. "These will help to reduce the risk of developing a venous thrombus." Pneumatic compression devices improve venous circulation and prevent deep vein thrombosis (DVT), making this the most accurate response.

Correct Answer is D

Explanation

A. Elbows and behind the ears: These areas are not primary pressure points in a seated position.

B. Coccyx and back of the skull: The coccyx is a pressure point when lying down, but this patient is sitting most of the time.

C. Heels and trochanter: Heels are at risk in supine patients, but this patient is primarily sitting.

D. Sacrum and ischium: The sacrum and ischium (sit bones) bear the most pressure in a seated position, making them highly vulnerable to skin breakdown.

A. "This new room has negative pressure and does six to twelve air changes an hour and disposes the air outside to reduce the infection potential in other patients. I also have to wear this surgical mask" B. "It sounds like you have some questions about your new diagnosis. What are you most concerned about?" C. "Tuberculosis can seriously impair the lungs and requires a long course of antibiotics to treat it D. “Tuberculosis is a small particle that can spread through the air. This new room has a special filter that reduces the spread of the bacteria through the air."

Correct Answer is D

Explanation

While this provides technical information, the surgical mask part is incorrect; the nurse should wear an N95 respirator, not a surgical mask.

B. "It sounds like you have some questions about your new diagnosis. What are you most concerned about?"

While this is a therapeutic communication technique, it does not directly answer the patient's question about airborne precautions.

C. "Tuberculosis can seriously impair the lungs and requires a long course of antibiotics to treat it."

This statement provides disease information but does not explain why airborne isolation is necessary.

D. "Tuberculosis is a small particle that can spread through the air. This new room has a special filter that reduces the spread of the bacteria through the air."

This provides a concise and accurate explanation of airborne precautions in terms the patient can understand.
