Postoperative and Emergency Care Flashcards

A patient in the Post-Anesthesia Care Unit (PACU) who received a volatile anesthetic and succinylcholine begins to exhibit unexplained tachycardia, muscle rigidity, and a rapid rise in end-tidal CO2. Which of the following is the priority emergency intervention?

Answer: Administering intravenous dantrolene sodium.

The patient's signs and symptoms—tachycardia, muscle rigidity, and hypercarbia following exposure to triggering anesthetic agents—are classic indicators of a malignant hyperthermia (MH) crisis. The definitive and priority treatment is the immediate administration of intravenous dantrolene, a muscle relaxant that directly inhibits calcium release from the sarcoplasmic reticulum, thereby halting the hypermetabolic process. While cooling measures and airway management are crucial supportive therapies, they do not correct the underlying pathophysiology like dantrolene does.

A CSFA is called to the bedside of a postoperative patient who states they 'felt something pop' after a strong cough. The CSFA observes the abdominal incision has separated and a loop of bowel is protruding. What is the most appropriate initial action?

Answer: Cover the protruding bowel with a sterile saline-moistened gauze.

This scenario describes wound evisceration, a surgical emergency. The immediate priority is to protect the exposed viscera from drying out and becoming contaminated. This is achieved by covering the protruding bowel with sterile gauze moistened with sterile saline. Attempting to reduce the bowel is contraindicated as it can cause further trauma and introduce infection. A dry dressing would adhere to the tissue, and a high-Fowler's position would increase intra-abdominal pressure. The patient should be placed in a low-Fowler's position with knees flexed.

In the immediate postoperative period, a patient's surgical drain output suddenly increases to 300 mL of bright red blood within one hour, and their heart rate rises from 85 to 120 bpm while their blood pressure drops. Which of the following is the most likely cause?

Answer: Postoperative hemorrhage

The combination of high-volume, sanguineous drain output, tachycardia (a heart rate over 100 bpm), and hypotension are classic signs of active postoperative hemorrhage. Tachycardia is often the earliest sign of hypovolemia as the body compensates for blood loss. The other options are less likely; a transfusion reaction has different signs (fever, chills, back pain), infection would not present so acutely with massive bleeding, and anesthetic effects should be waning, not causing progressive instability.

A patient who underwent a total hip arthroplasty 3 days ago suddenly develops acute shortness of breath, pleuritic chest pain, and tachycardia in the recovery area. Which of the following life-threatening conditions should be suspected first?

Answer: Pulmonary Embolism

The triad of sudden dyspnea, pleuritic chest pain, and tachycardia in a postoperative patient, especially after major orthopedic surgery, is highly suggestive of a pulmonary embolism (PE). Major surgery and immobility are significant risk factors for deep vein thrombosis (DVT), the most common cause of PE. While the other conditions are possible, the acute onset and specific symptom constellation make PE the most critical initial diagnosis to consider.

While assisting with patient transport, a chest tube is accidentally pulled out completely from the patient's pleural space. Which of the following is the correct immediate emergency action?

Answer: Apply pressure with a gloved hand and cover the site with an occlusive dressing taped on three sides.

If a chest tube is accidentally removed, the priority is to prevent air from entering the pleural space and causing a tension pneumothorax. The correct emergency procedure is to immediately cover the insertion site with a sterile occlusive (petroleum) dressing, taping it on only three sides. This creates a flutter valve effect, allowing air to escape from the pleural space during exhalation but preventing it from entering during inhalation. Reinsertion is a sterile procedure done by a provider, and submerging the tube is the action for a system disconnection, not a complete removal.

A patient in the PACU, shortly after extubation, develops inspiratory stridor, use of accessory muscles, and paradoxical chest movements ('see-saw' breathing) with no audible air movement. This is most indicative of what emergency?

Answer: Complete Laryngospasm

The signs described—inspiratory stridor progressing to silence, paradoxical chest movements, and retractions despite respiratory effort—are classic manifestations of a complete laryngospasm. This is a complete, involuntary closure of the vocal cords, creating a total upper airway obstruction. Bronchospasm typically involves wheezing on exhalation. Pulmonary edema and aspiration would present with different lung sounds (crackles/rales) and would not typically cause a silent, obstructive upper airway pattern.
