Question 1 of 10

A patient with severe preeclampsia is receiving magnesium sulfate. She becomes somnolent, respiratory rate falls to 7/min, and patellar reflexes are absent. Which treatment should be administered immediately while ventilatory support is provided?

Give another magnesium sulfate bolus

Give intravenous furosemide as sole therapy

Give intravenous calcium gluconate

Give intravenous sodium bicarbonate

Question 2 of 10

Parasternal short-axis echocardiographic view showing a markedly enlarged right ventricle and interventricular septal flattening with a relatively small left ventricle.

Immediately after placental delivery, a patient with suspected amniotic fluid embolism develops severe hypoxemia, refractory hypotension, and diffuse bleeding from intravenous sites. Norepinephrine is running, and a balanced massive transfusion protocol with tranexamic acid has begun. Point-of-care echocardiography is shown. Which additional hemodynamic therapy best addresses the dominant abnormality demonstrated?

Start inhaled nitric oxide therapy

Give atropine despite normal rate

Give rapid two-liter crystalloid bolus

Start intravenous nitroprusside infusion

Question 3 of 10

An adult with Parkinson disease requires general anesthesia and has a high risk of postoperative nausea. Dopaminergic therapy has been continued as close to surgery as possible. Which antiemetic strategy best avoids worsening the underlying movement disorder?

Use prochlorperazine rather than a serotonin antagonist

Use metoclopramide rather than a serotonin antagonist

Use ondansetron rather than a dopamine antagonist

Use droperidol rather than a serotonin antagonist

Question 4 of 10

Pediatric chest radiograph showing marked unilateral left-lung hyperinflation with mediastinal displacement following peanut aspiration.

A 3-year-old develops sudden coughing and unilateral wheeze while eating peanuts. Oxygen saturation is 96% on room air and the child is not in distress. The chest radiograph is shown. A pediatric ENT team experienced in rigid bronchoscopy is immediately available. Which next step is most appropriate?

Observe overnight because oxygen saturation remains normal

Perform flexible bronchoscopy under light procedural sedation first

Proceed to rigid bronchoscopy under controlled anesthetic conditions

Order chest CT before planning any airway intervention

Question 5 of 10

During attempted separation from cardiopulmonary bypass after open left-heart surgery, transesophageal echocardiography reveals substantial intracardiac air despite adequate ventricular function. Which action is most appropriate before completing separation?

Complete bypass separation without further de-airing

Permit full ventricular ejection despite residual air

Continue de-airing before allowing full ventricular ejection

Increase contractility to expel intracardiac air rapidly

Question 6 of 10

During carbon dioxide laser microlaryngeal surgery, a flash and flame are suddenly seen emerging from the laser-resistant tracheal tube, followed by smoke in the breathing circuit. What immediate sequence should the anesthesia team perform?

Stop laser and gases, remove tube, flood airway with saline.

Remove tube, continue oxygen flow, extinguish fire with dry gauze.

Stop laser only, leave tube, ventilate with 100% oxygen.

Stop gases only, leave tube, continue laser after smoke clears.

Question 7 of 10

During cardiac surgery after patient repositioning, the pulmonary artery catheter tracing abruptly changes to a right-ventricular waveform and frequent ventricular ectopy appears. The catheter had previously been correctly positioned. Which action is most appropriate?

Reposition the catheter under waveform guidance

Advance the catheter blindly without monitoring

Leave the catheter in the right ventricle

Inflate the balloon within the right ventricle

Question 8 of 10

During endovascular thrombectomy for acute ischemic stroke under general anesthesia, systolic arterial pressure falls from 170 to 105 mmHg after induction before reperfusion has been achieved. Oxygenation and ventilation are adequate. Which anesthetic priority is most appropriate?

Maintain the lower pressure until reperfusion is completed

Correct the hypotension promptly to preserve cerebral perfusion

Reduce systolic pressure further to below 100 mmHg

Hyperventilate deliberately instead of correcting the arterial pressure

Question 9 of 10

One-lung ventilation has been stable for 40 minutes during lobectomy. Immediately after vigorous surgical manipulation near the hilum, oxygen saturation falls from 98% to 87% and airway pressures change. Which diagnostic step should be performed promptly?

Reduce inspired oxygen while waiting for spontaneous improvement

Increase dependent-lung PEEP without reassessing device position

Give additional intravenous fluid before reassessing lung isolation

Reconfirm lung-isolation device position with flexible bronchoscopy

Question 10 of 10

A deeply sedated patient is undergoing a painful procedure in a small office-based suite located several floors from the hospital emergency department. The facility has standard monitors but no defibrillator or emergency transfer protocol. Which decision is most appropriate?

Proceed because standard physiologic monitoring is available

Call emergency services only if deterioration later occurs

Do not proceed until emergency resources are adequate

Proceed because the patient is currently hemodynamically stable
