Mr. Hendersоn, а 52-yeаr-оld mаle, was оn his way to work during a heavy rainstorm when he lost control of his car and crossed into oncoming traffic where he collided head-on with a small delivery truck. Witnesses accessed the 911 emergency medical response system, and paramedics arrived quickly. The driver of the truck suffered only minor cuts and scrapes, but Mr. Henderson was having difficulty breathing and complaining of severe chest pain. Transport time to the nearest trauma center was less than two minutes, so the emergency personnel elected to "scoop and haul." A large bruise on his chest indicated that Mr. Henderson had experienced blunt trauma from the impact of the steering wheel after the airbag failed to deploy. Mr. Henderson presented in the ER with blurred vision, dizziness, headache, nausea, muscle weakness, hypoventilation, and a feeling of mental confusion. A chest X-ray revealed bilateral fractures in the fourth, fifth, and sixth ribs along with a suspected hemothorax. An ECG revealed signs of ventricular arrhythmias. The following values were taken from the results of an arterial blood gas (ABG) and urinalysis (UA). Arterial Blood Gas (ABG) High or Low pH: 7.0 Low PCO2: 62 High bicarbonate: 29 mEq/L High Urinalysis (UA) pH: 4.0 Low Questions: 1) Mr. Henderson's PCO2 is elevated. Under normal conditions, what would be the PRIMARY mechanism that his body would use to reduce the amount of PCO2 in the blood? Why is this mechanism not working in this case? 2) Describe how the high PCO2 and low pH in Mr. Henderson's blood are related in this case. 3) Describe how the high bicarbonate in Mr. Henderson's blood is related to the low pH in his urine. 4) What type of intervention might the doctors and nurses initiate to address the hemothorax? Explain how this intervention will lead to changes in PCO2 and blood pH.
Peggy Fender is well knоwn tо the emergency depаrtment (ED) stаff. She's а 59-year-оld woman whose visit today is similar to her frequent visits in the past. She arrives in the afternoon, appearing intoxicated and complaining of abdominal pain, particularly in the right upper quadrant (RUQ) of her abdominopelvic cavity. "Another Fender bender," a nearby nurse whispers to Tim, the new physician assistant (PA) who is due to examine Mrs. Fender. Tim proceeds with his physical examination. Mrs. Fender appears emaciated with bruising of various ages on her arms, legs, and face. She is jaundiced (yellow-skinned) and has a strong smell of alcohol on her breath. Tim palpates the inferior border of her liver, which is hard and enlarged; Mrs. Fender moans with pain. Her entire abdomen is ascitic (swollen and fluid-filled). Mrs. Fender is not entirely coherent; she knows where she is and who she is, but is unable to relate anything about her present illness except a slurred, "My stomach hurts; quit poking it, you idiot!" Her coordination is poor when she attempts to sit or stand. She becomes annoyed and indignant when Tim asks her how much alcohol she's had to drink today even though she is obviously inebriated. Tim reviews her blood tests, which reveal elevated blood transaminases (liver enzymes), high blood glucose (hyperglycemia), and prolonged prothrombin time (PT — slowed clotting time). Based on her history, and present findings, Tim diagnoses Mrs. Fender with alcoholic cirrhosis, which is the result of chronic inflammation of the liver from heavy, consistent alcohol ingestion. If alcohol abuse continues long-term, it leads to fat accumulation in the liver, followed by fibrosis and severe liver dysfunction. Questions: Besides the nurse's "bender" comment, and Mrs. Fender's social history, Tim suspects alcohol abuse based on many of his physical exam findings. Name at least THREE signs and/or symptoms that point to alcoholism, and briefly explain why each sign/symptom may occur. Mrs. Fender's jaundice is caused by the accumulation of bilirubin in her blood and tissues. What is the normal fate of bilirubin, and what role does the liver play? Explain how Mrs. Fender's cirrhosis is related to her jaundice. Mrs. Fender's prolonged clotting times and excessive bruising are related. Again, referring to normal physiological functioning of the liver, why do these two things happen when alcohol damages hepatocytes?
