Question 1

Which of the following is the primary reason for using a cuffed endotracheal tube in surgical patients under general anesthesia?

Accepted Answer

To prevent anesthetic gas leakage and protect the airway from aspiration

Answer

A cuffed ETT seals the trachea to prevent aspiration of fluid or ingesta and reduces waste anesthetic gas leakage into the room.

Question 2

What is the primary purpose of a sterile drape during surgery?

Accepted Answer

To establish and maintain a sterile field around the incision site

Answer

Sterile drapes demarcate and maintain the sterile field surrounding the incision, preventing contamination from nonsterile surfaces.

Question 3

During a splenectomy, the circulating nurse notices a sponge count discrepancy. The CORRECT immediate action is to:

Accepted Answer

Notify the surgeon immediately so the body cavity can be searched

Answer

A sponge count discrepancy before closure requires immediate notification of the surgeon to search the cavity before it is closed to prevent a retained foreign body.

Question 4

Which anesthetic monitoring parameter MOST directly reflects cardiac output during surgery?

Accepted Answer

End-tidal CO2 (EtCO2)

Answer

EtCO2 closely reflects cardiac output because CO2 delivery to the lungs depends on pulmonary perfusion; a sudden drop often indicates reduced cardiac output.

Question 5

Monofilament suture material is preferred over multifilament in contaminated wounds primarily because:

Accepted Answer

It has less capillarity and reduces bacterial wicking

Answer

Monofilament suture has a smooth surface with no interstices, reducing capillarity and the risk of bacteria being wicked along the suture into the wound.
