A patient presents to the preoperative clinic with hypertension. Which statement about hypertension is MOST likely true? (A) (B) (C) (D) 83. A pulse pressure (systolic minus diastolic blood pressure) of more than 65 mm Hg increases the risk of stroke. Pulse pressure greater than 65 mm Hg is caused by increased elastic recoil of the major conducting vessels (eg, aorta). Isolated systolic hypertension is usually first diagnosed in patients less than 50 years of age. Isolated diastolic hypertension is the most common form of hypertension in patients over 50 years old. After an initial blood pressure determination of 195/65 mm Hg, repeat determinations are 175/55 mm Hg and 180/50 mm Hg. There is no other preoperative information available. The patient asks if there are any additional perioperative risks of proceeding with elective surgery. Which of the following assessments of her status is MOST accurate? (A) (B) (C) (D) Elective surgery should be canceled when systolic blood pressure is consistently above 170 mm Hg. Diabetes mellitus is associated with pulse pressure hypertension. Postoperative renal injury is not influenced by the presence of pulse pressure hypertension. Perioperative mortality is lowest in ambulatory patients with a diastolic blood pressure below 70 mm Hg. 18 INSTRUCTIONS FOR ITEMS 84 THROUGH 86: This series of items refers to the diagnosis, treatment or management of a single patient. 84.

After appropriate treatment, the patient’s diplopia and nystagmus resolve. He presents for his ankle surgery. He has continued to take ginseng on a regular basis and recently began taking ginger. Which statement about his anesthetic management is MOST likely true? (A) (B) (C) (D) Neuraxial anesthesia is contraindicated. He is at increased risk for postoperative nausea. The herbal remedies should be discontinued 24 hours before surgery. He is at increased risk for hypoglycemia. INSTRUCTIONS FOR ITEMS 89 AND 90: This series of items refers to the diagnosis, treatment or management of a single patient. 89. As opposed to a smaller prophylaxis dose, a patient is receiving a dose of 1 mg/kg enoxaparin every 12 hours for treatment of a deep venous thrombosis. The patient is scheduled for surgery under neuraxial anesthesia. The MOST appropriate time to proceed with the surgery would be (A) (B) (C) (D) 90. 24 hours from the last dose. when the prothrombin time is normal. 12 hours from the last dose. when an activated partial thromboplastin time is normal. During placement of the epidural in this patient some blood is noted in the epidural catheter. The blood is cleared and does not reappear. In managing this situation, which of the following is MOST appropriate? (A) (B) (C) (D) Keep the anti-factor Xa level less than 0.2 U/mL for 24 hours after surgery. Postpone surgery for 24 hours and then perform a general anesthetic. Delay the next enoxaparin dose until 24 hours after surgery. Advise the surgeon this patient is not at increased risk of spinal hematoma. 20 INSTRUCTIONS FOR ITEMS 91 AND 92: This series of items refers to the diagnosis, treatment or management of a single patient. 91. A 75-year-old female with a cardiac rhythm management device (CRMD) with defibrillation capabilities presents for an elective abdominal hysterectomy. Which of the following statements about her preoperative management is MOST likely true? (A) (B) (C) (D) 92. The pacing rate should be reduced. Preoperative interrogation is not indicated if bipolar electrocautery is used. All antitachycardia therapy should be disabled. Minute ventilation responsiveness, if present, should be enabled. A magnet is placed over the generator of the cardiac rhythm management device (CRMD). Which statement about the consequences of this action is MOST likely true? (A) (B) (C) (D) All devices will automatically convert to an asynchronous pacing mode. Antitachycardia therapy may be disabled by the magnet. Placement of a magnet will not have any effect on the function of a CRMD with defibrillation capabilities (an ICD). Programming will always return to the original mode when the magnet is removed. 21 INSTRUCTIONS FOR ITEMS 93 AND 94: This series of items refers to the diagnosis, treatment or management of a single patient. 93. A 73-year-old male is undergoing general anesthesia for coronary artery revascularization. Shortly after induction, the monitor reveals a change in his electrocardiogram from normal sinus rhythm to the following: This cardiac rhythm is BEST described as (A) (B) (C) (D) 94. first-degree atrioventricular (AV) block. second-degree Mobitz type I AV block. second-degree Mobitz type II AV block. third-degree heart block. The rhythm persists and after sternotomy, the patient’s blood pressure decreases to 70/40 mm Hg. Which of the following therapeutic maneuvers would be MOST appropriate?

A 67-year-old, 81 kg woman with a history of asthma and hypertension has undergone a vaginal hysterectomy under general anesthesia. Induction was performed with fentanyl, propofol, and vecuronium (single 6 mg dose); sevoflurane was used for maintenance of anesthesia. Antibiotic prophylaxis was provided with clindamycin. No other drugs were administered. At the end of the 90-minute procedure train-of-four (TOF) ulnar nerve stimulation produces four observed twitches without fade. Which of the following statements is MOST likely true? (A) (B) (C) (D) 96. Reversal drugs are administered and the patient extubated. Immediately prior to extubation a small amount of fade was evident on train-of-four (TOF) stimulation. In the postanesthesia care unit (PACU), she is tachypneic and complains of difficulty breathing and swallowing. Which of the following statements is MOST likely true? (A) (B) (C) (D) 97. Her measured TOF ratio (fourth twitch:first twitch) will be greater than 0.9. She does not need reversal of the nondepolarizing muscle relaxant. Sevoflurane delays the recovery of TOF after neuromuscular reversal. She will have a strong hand grip. She will be able to maintain her normal tidal volume. Her ability to manage her oral secretions has returned to normal. Her risk of hypoxic episode is less than 1%. She will be able to speak clearly. Over the next 90 minutes, the patients experiences several desaturation episodes. On a chest radiograph she has bilateral atelectasis. Her arterial blood gas analysis is PaO2 85 mm Hg, PaCO2 29 mm Hg, pHa 7.51, with an FIO2 of 0.4. You arrange for an intensive care unit bed. She complains of feeling weak and having difficulty swallowing. Which of the following statements is MOST likely true? (A) (B) (C) (D) She aspirated gastric contents during the surgical procedure.
