A postoperative surgical patient asks how the sequential compression boots applied in the operating room will help lower the risk of blood clots forming in the legs. The nurse's most appropriate response would be that the boots:

alternately compress and release to help blood flow through vessels.

measure pressure in the leg blood vessels and sound an alarm if pressure rises.

provide gentle continuous compression at low pressure.

provide firm continuous compression at high pressure.

Answer and Explanation

The Correct Answer is A

A. Alternately compress and release to help blood flow through vessels. Sequential compression devices (SCDs) work by alternating compression and release to promote venous return, prevent stasis, and reduce the risk of deep vein thrombosis (DVT). This is the correct mechanism of action for these devices.

B. Measure pressure in the leg blood vessels and sound an alarm if pressure rises. SCDs do not measure pressure; they are designed to apply intermittent pressure to the legs to encourage circulation and prevent clot formation.

C. Provide gentle continuous compression at low pressure. SCDs apply intermittent pressure, not continuous pressure. Continuous compression would not be effective in preventing DVT as it does not allow for the periodic relaxation of veins.

D. Provide firm continuous compression at high pressure. SCDs should apply intermittent, not continuous, pressure. High pressure could potentially harm the patient’s circulation and tissues, which is why the compression is designed to be gentle and alternating.

Correct Answer is A

Explanation

A. When still conscious, participate in marking the surgical site. The surgical site marking should be done with patient participation before anesthesia to confirm accuracy and prevent wrong-site surgery.

B. Have a photograph of the surgical site in the medical record. Photographs are not a standard requirement for surgical verification.

C. Have the unit nurse confirm their identity. Identity confirmation is necessary but not sufficient to prevent wrong-site surgery. Marking the site is the key step.

D. Verbally state the location of the surgical site and the expected procedure. Verbal confirmation is important but should be combined with physical marking of the site to ensure accuracy.

A. list the patient off the unit on the computer. B. tell the family how to get to the surgical waiting room. C. assist with the transfer of the patient to the stretcher. D. verify the patient's ID number with the medical record and transport slip.

Correct Answer is D

Explanation

A. List the patient off the unit on the computer. Listing the patient off the unit in the computer is important for tracking, but this is not the most immediate priority when transporting the patient. Verifying the patient's identity is more crucial to prevent errors in patient care.

B. Tell the family how to get to the surgical waiting room. While it is helpful to guide the family to the surgical waiting room, the nurse's primary responsibility when the transport person arrives is to ensure the patient is correctly identified and safely transferred.

C. Assist with the transfer of the patient to the stretcher. Assisting with the transfer is important for patient safety, but the most important step is verifying the patient's identity to ensure the correct procedure is being performed.

D. Verify the patient's ID number with the medical record and transport slip. The most important task when the transport person arrives is to verify the patient's identity to prevent errors. The nurse must confirm the patient’s identity by checking the ID number against the medical record and transport slip before the patient is transferred to avoid any mistakes.
