Anesthesiology MCQs (Prometric)

An anesthesiologist will remain beside a patient during a prolonged fluoroscopically guided interventional radiology procedure. Repeated imaging is expected. Which occupational strategy best reduces cumulative radiation exposure?

An 80-kg adult arrives 2 hours after sustaining 30% TBSA partial- and full-thickness burns. He has already received 500 mL of lactated Ringer solution. Using an initial estimate of 2 mL/kg/%TBSA for the first 24 hours, with half delivered during the first 8 hours from injury, what initial hourly rate is required for the next 6 hours?

Immediately before an ultrasound-guided regional block, the consent form specifies the left side but the operating list specifies the right side. The patient is already sedated but responsive. What should the anesthesiologist do first?

During prone interventional radiology under deep propofol sedation, a patient repeatedly develops obstructive apnea. The head is partially inaccessible beneath imaging equipment, jaw thrust provides only transient improvement, and the procedure has another 90 minutes remaining. What is the safest next step?

Near completion of a craniotomy, the surgeon reports that a substantial intracranial air space remains. Nitrous oxide has been part of the anesthetic. Which anesthetic adjustment is most appropriate?

During a multidisciplinary perioperative meeting, a senior physician repeatedly humiliates a nurse who raises a legitimate concern about a patient's deterioration. The behavior is disrupting communication and making junior staff reluctant to speak. Which professional response is most appropriate?

A patient takes clonidine chronically for hypertension and is scheduled for surgery tomorrow. Blood pressure is well controlled, and there is no plan to discontinue antihypertensive therapy generally. Which medication strategy best prevents a withdrawal complication?

A term patient develops an umbilical cord prolapse with persistent profound fetal bradycardia. No neuraxial catheter is present, and immediate cesarean delivery is required. Which anesthetic technique is most appropriate?

During parenchymal transection in an elective right hepatectomy, an adult remains hemodynamically stable and has no significant cardiac or renal disease. Which intraoperative hemodynamic target best reduces hepatic venous bleeding during the transection phase?

Five days after cesarean delivery under neuraxial anesthesia, a patient develops a severe new headache that is not posture-dependent, followed by a focal seizure and left-arm weakness. Which next step is most appropriate?
