In order for the anesthesiologist to accurately calculate the amount of anesthesia needed for an 82-year-old patient, the nurse should have data available on the medical record, such as:

A. "They'll improve your circulation to keep blood from pooling in your legs." Antiembolism stockings apply graduated compression, promoting venous return and preventing deep vein thrombosis (DVT) by reducing blood stasis.

B. "They'll make it easier for you to do leg exercises after your surgery." Leg exercises help prevent DVT, but antiembolism stockings do not directly assist in performing them.

C. "They'll protect your legs and heels from skin breakdown." While stockings provide some skin protection, their primary function is to prevent venous stasis and embolism, not to prevent pressure ulcers.

D. "They'll help keep you warm immediately after your surgery." Stockings are not primarily designed for warmth; their main purpose is to prevent clot formation by improving circulation.

A. The opinion of a second surgeon is sought regarding the necessity of the surgery. This is an appropriate course of action when consent cannot be obtained from the patient or family, especially in emergency situations to ensure the necessity of surgery.

B. The surgeon will write a detailed note about the need for surgery and a registered nurse will then sign the consent. RNs do not have the legal authority to sign surgical consent forms, which should be signed by a legal guardian or the healthcare provider in emergencies when appropriate.

C. The hospital social worker can sign the permit. Social workers do not have the authority to sign consent forms. Consent must typically come from a legally authorized individual.

D. The hospital attorney must authorize the surgery and sign the consent form. The hospital attorney is not typically involved in emergency decision-making about surgery unless there are significant legal concerns, which is not the case in this scenario.
