Question 21

A 70-year-old man with a history of tobacco abuse, hypertension, prior stroke, and laryngeal cancer is brought to the emergency department after being found unresponsive at his home. It is estimated by family members that he lost consciousness approximately one hour earlier. He underwent a total laryngectomy ten years prior with no subsequent evidence of recurrent cancer. His current medications include Ramipril and a daily aspirin. On physical examination, the patient is nonresponsive to voice or painful stimuli and his respirations are shallow. Vital signs are: Temperature 37.9oC (98.9oF), blood pressure is 200/100 mm Hg, pulse is 93/min, and respirations are 13/min, and an O2 saturation level of 87%. There are no apparent signs of trauma secondary to a fall. The pupils are small, but equal and reactive. The patient’s tracheostoma is widely patent; breath sounds are distant but present bilaterally without crackles. An arterial blood gas reveals pH 7.25, PaO2 45. Which of the following is the most appropriate next step in management?

Answer 21

Question 22

A 69-year-old man had a gastric tube placed one day ago. The patient has a long history of dementia secondary to Alzheimer disease and was admitted to the hospital for failure to thrive (FTT). A full evaluation revealed only severe dementia but no obvious cause for the FTT. A swallowing study was performed that indicated likely aspiration of all oral foods. After discussion with the family, a decision was made to place a gastric tube for the purposes of feeding. The surgery was uneventful, and the patient appears to be doing well during a routine postoperative check. Later that evening, the patient is found severely obtunded. He is now 34 hours postoperative. He has been getting tube feedings for the past five hours and had minimal gastric residuals at the 2-hour check time. On arrival, he is cyanotic with labored breathing. His pulse oximeter reads 85% on 100% non-rebreather mask. On inspection of the patient’s mouth and oropharynx, there are tube feedings visible. What is the most likely etiology of this patient’s respiratory distress?

Answer 22

Regurgitation and aspiration of gastric tube infused tube feedings

Question 23

A patient has an anterior neck injury, hoarseness, labored respirations, subcutaneous emphysema, and laryngeal crepitus following a motor vehicle accident. Which of the following is the best method of securing the airway in this situation?

Answer 23

Tracheostomy

Question 24

Answer 24

Normal saline infusion

Question 25

Cardiopulmonary resuscitation is being performed on a patient. After successful intubation, arterial blood gas values are PaO2: 86 mm Hg and PaCO2: 63 mm Hg, pH is 7.25 at a FiO2 of 1.0. What is the most appropriate next step in management of the patient at this time?

Answer 25

Hyperventilate the patient
