The nurse understands that sequential compression devices and compression stockings are used for which of the following?
Protect the muscles of the lower extremities from atrophy.
Keep the blood from pooling in lower extremities to avoid clots.
Keep the patient from getting sores on the skin.
Keep the patient’s joints in working order.
The Correct Answer is B
A. Protect the muscles of the lower extremities from atrophy:
This statement is not the primary purpose of sequential compression devices (SCDs) and compression stockings. While these devices can help maintain muscle tone by promoting blood circulation, their primary function is to prevent blood pooling and reduce the risk of deep vein thrombosis (DVT).
B. Keep the blood from pooling in lower extremities to avoid clots:
This is the correct purpose of sequential compression devices and compression stockings. They are designed to promote venous return and prevent blood from pooling in the lower extremities, thereby reducing the risk of blood clots, especially in individuals at risk for deep vein thrombosis (DVT).
C. Keep the patient from getting sores on the skin:
Preventing sores on the skin is not the primary purpose of these devices. While improved circulation may contribute to skin health, preventing skin sores is not the primary therapeutic goal of SCDs and compression stockings.
D. Keep the patient’s joints in working order:
Maintaining joint function is not the primary purpose of sequential compression devices and compression stockings. These devices primarily focus on promoting venous circulation and preventing complications related to blood pooling and clot formation.

Correct Answer is B
Explanation
A. 20 bpm: This is twice the calculated rate, so it's significantly higher than observed.
B. 10 bpm: This matches closely with the calculated rate of approximately 10.23 breaths per minute.
The scenario describes the nurse counting the client's breaths starting from when the second hand of the clock was at 12 and ending just past 5, and the client completed 9 breaths during this time frame.
Counting Period:
From just past 12 to just past 5 on the clock, the time span is approximately 53 seconds.
Number of Breaths:
The client completed 9 breaths within this time frame.
Now, to calculate the respiratory rate:
Respiratory rate = (Number of breaths / Time in minutes)
Respiratory rate = (9 breaths / 0.88 minutes) (53 seconds converted to minutes)
After calculation, the respiratory rate is approximately 10.23 breaths per minute.
C. 09 bpm: This is a lower value than observed and doesn't align with the counted breaths.
D. 18 bpm: This is close to double the observed rate, which doesn't match with the counted breaths within the time frame.
Correct Answer is C
Explanation
A. Do not let the patient know you are counting their respirations:
This is not directly related to obtaining vital signs and is not a critical factor for a patient with a low platelet count.
B. Let the patient rest for 5 minutes before you measure their blood pressure:
Allowing the patient to rest for a few minutes before measuring blood pressure is a good practice but may not be as critical as other considerations in a patient with a low platelet count.
C. Do not measure the patient’s temperature rectally:
Patients with low platelet counts are at an increased risk of bleeding. Rectal temperatures can be invasive and carry a risk of mucosal injury, making them less advisable in patients with bleeding risks.
D. Count the patient’s radial pulse for 30 seconds and multiply it by 2:
Counting the radial pulse is a suitable method for assessing heart rate in a patient at risk for bleeding. However, rectal temperature measurement should be avoided due to the risk of mucosal injury.
