50. According to the American Society of Anesthesiologists: "Practice advisory for the prevention and management of operating room fires, " which of the following is considered a best practice?
For every case the entire OR team should take part in determining whether a significant fire risk exists and should jointly take active roles in mitigating the risk of fire.
High FiO2 at high flows should be used for sedation procedures to lessen the risk of oxygen accumulation under the drapes.
Nitrous oxide should be used as an anesthetic adjunct to mitigate the fire risk of 100% FiO2 .
Unipolar electrocautery should be used ahead of bipolar electrocautery to mitigate the risk of fire.

You are performing a laparoscopic cholecystectomy on a 49-year-old obese woman with a past medical/surgical history of a right-sided mastectomy and lymph node dissection for breast cancer, hepatitis C, and a remote history of IV drug abuse. As you attempt to place the IV, you note that the patient does not have many sites where an IV can be placed. Even after utilizing ultrasound, you can only see the median cubital vein clearly on the right. The patient tells you she has always been told to never let anyone place an IV on her right arm. Which of the following do you inform the patient?
She may need central vascular access if no superficial cite can be found.
The median cubital vein on the ipsilateral side of her previous surgical procedure should be utilized because there is poor evidence that needlesticks on the same side as a previous lymph node dissection contribute to lymphedema.
Venous access on the ipsilateral side of her mastectomy and lymph node dissection is unlikely to cause lymphedema if good skin hygiene is utilized following the procedure.
She should have a peripherally inserted central catheter line placed under fluoroscopy.

Regarding perioperative considerations for lung transplantation (LTx), which of the following statements are true?
Compared with donation-after-brain-death LTx, donation-after-circulatory-death (DCD) LTx results in decreased graft survival.
Perioperative hyperglycemia is associated with increased mortality in patients undergoing LTx.
Use of lung protective ventilation strategies in organ donors with brain death has not increased the number of available donor lungs.
Lung transplant using cardiopulmonary bypass (CPB) provides better long-term outcomes compared with off-pump LTx.

33. A 59-year-old man with a history of mild hypertension, hyperlipidemia, and B-cell lymphoma with doxorubicin-induced cardiomyopathy requiring orthotopic heart transplantation 5 years ago is brought in by EMS to the ED. His posttransplant course was complicated by postoperative renal failure with permanent need for dialysis. He presents now in shock. He does not follow a renal diet but has undergone a routine hemodialysis 2 days ago. "He only takes tacrolimus and mycophenolate mofetil" at home per EMS report. His vitals are HR 115, BP 74/41, RR 35, and O2 Sat 85% on 10 L FM. The patient's ECG shows ST elevations in multiple leads, his troponin I is 0.4, and serum lactate is 6. Before he can be brought to a heart catheterization laboratory, the patient passes away. Which of the following medications/intervention most likely would have helped prevent this situation?
Pravastatin
Aspirin
Diltiazem
Prophylactic coronary angioplasty with left main coronary artery stent deployment

Which of the statements regarding thyroid function and its impacts on cardiovascular pathophysiology is most likely true?
Pulmonary hypertension is linked to hyper- and hypothyroidism.
Hypothyroidism is associated with a slower progression of heart failure patients.
Triiodothyronine (T3)/thyroxin (T4) therapy to the donor increases availability of thoracic donor organs but causes increased graft rejection after transplantation.
T3 levels do not correlate with the presence of coronary artery disease.

Patients with end-stage heart failure pending heart transplantation may require
Intra-aortic balloon pump (IABP) counterpulsation raises the effective cardiac output more than percutaneously inserted axial flow pumps (eg, Impella).
Percutaneously inserted axial flow pumps (eg, Impella) generally do not require anticoagulation while inserted.
Extracorporeal membrane oxygenation (ECMO) decreases left ventricular (LV) afterload less than IABP.
It is recommended to continue supportive catecholamine infusions with indwelling percutaneously inserted axial flow pumps to enhance cardiac output.

You are taking care of an otherwise healthy 35-year-old man undergoing repair of his left anterior cruciate ligament. Shortly after induction, his heart rate increased from 70 to 110 beats per minute and his blood pressure drops to 60/40 mm Hg. You also notice an increase in his peak inspiratory pressure. Which of the following is your next step?
Administer a 500-cc bolus of crystalloid, and turn down the concentration of volatile anesthetic.
Start a phenylephrine infusion to target an MAP greater than 60 mm Hg.
Call for help, give epinephrine 10-100 µg IV, and repeat or escalate dose every 1-2 minutes and titrate to effect.
Call for help, and give epinephrine 1 mg IV.

37. The following scenario applies to the next 3 questions: You are asked to evaluate a 65-year-old 80-kg man in the postanesthesia care unit (PACU). He has just undergone a laser lithotripsy of a right ureteral stone. His temperature is 38.5°C, heart rate is 100 beats per minute, blood pressure is 83/55 mm Hg, and respiratory rate is 30 breaths per minute. He is arousable but confused. He has already received 2 L of crystalloid in the perioperative period. The most appropriate next step in management is administration of which of the following?
Start norepinephrine infusion, and titrate to MAP >65 mm Hg.
Start dopamine infusion, and titrate to MAP >65 mm Hg.
Start phenylephrine infusion, and titrate to SBP >90 mm Hg.
Give 250 cc of 5% albumin.

The patient is now on norepinephrine at 20 µg/min, and his MAP remains less than 65 mm Hg. The next appropriate step is which of the following?
Add dopamine as a second vasopressor.
Add phenylephrine as a second vasopressor.
Add vasopressin as a second vasopressor.
Decrease your MAP goal to 60 mm Hg, as his baseline pressure is usually low.

A 55-year old man is scheduled for elective colectomy. His medical history is significant for hypertension, which is controlled on lisinopril. Shortly after induction with propofol and rocuronium, his blood pressure decreases from 130/85 to 80/50 mm Hg. Administration of ephedrine 5 mg and phenylephrine 40 µg IV has no effect. The most appropriate treatment at this time is administration of which of the following?
