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."
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 B
Explanation
A. "It is okay to take laxatives every day to help you have a bowel movement." Frequent laxative use can lead to dependence and decreased bowel function over time. Instead, non-pharmacologic measures such as fiber intake, hydration, and physical activity should be encouraged first.
B."Do not ignore the urge to have a bowel movement even if you feel it is inconvenient." Ignoring the urge can lead to constipation as stool remains in the colon longer, resulting in increased water absorption and harder stools. Encouraging regular bowel habits helps maintain normal function.
C. "Do not take opiate medications as those can cause constipation." While opiates can cause constipation, this statement is too broad. Some individuals may require opioid therapy for pain management. Instead, the focus should be on preventing and managing opioid-induced constipation rather than avoiding these medications altogether.
D. "Be sure to eat at least 20 grams of fiber and drink at least 1,000mL per day." While increasing fiber intake is important, 20 grams may not be sufficient (the recommended daily fiber intake for older adults is about 25–30 grams). Additionally, 1,000 mL (1 liter) of fluid may be inadequate, as older adults should aim for at least 1,500–2,000 mL per day unless contraindicated.
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.
