Jen has been having issues digesting gluten throughout her life. Her doctors tell her that she has celiac disease, which is an autoimmune disease that is causing her immune system to attack the brush border of her , which then prevents absorption and causes illness when she consumes gluten.

Celiac disease is an autoimmune response in which the body attacks the brush border of the small intestine and therefore prevents proper nutrient absorption. The small intestine's brush border is made of many small protrusions called villi and microvilli, which increase surface area in order to increase absorption area. Without these areas of absorption, the body cannot absorb a sufficient amount of necessary nutrients from the diet.

A 47-year old woman is brought by ambulance to the trauma bay after being involved in a high-speed motor vehicle collision. She is unresponsive, with a blood pressure of 78/42 and pulse 132. She is immediately intubated and breath sounds are confirmed. Her heart sounds are normal and peripheral pulses are intact. There is no obvious bleeding and two large bore IVs are started. Abdominal ultrasound reveals a fluid collection in the left upper quadrant. She continues to deteriorate and is brought emergently to the OR for exploratory laparotomy, where packing of the abdomen reveals extensive bleeding in the left upper quadrant. What do you expect is the cause of this bleeding?

Blood collecting in the left upper quadrant would suggest a splenic laceration.
The spleen is one of the most commonly injured organs with blunt abdominal trauma. It can and will bleed enough to make a patient hemodynamically unstable. Ultrasound performed in the trauma bay looks at four potential spaces of fluid collection: Morrison's pouch (right upper quadrant/liver), splenorenal recess (left upper quadrant/spleen), subxiphoid (heart), and the pouch of Douglas (suprapubic/pelvis). The liver is located in the right upper quadrant of the abdomen and the spleen in the left upper quadrant
This patient's ultrasound showed fluid collection in the perisplenic space as well as extensive bleeding, which would suggest a splenic laceration as the cause of the patient's condition.
The liver is in the right upper quadrant. The right and left iliac arteries are in the right and left lower quadrants, respectively. Bladder laceration would result in fluid collection in the pelvis.

Salmonella is an illness caused by a bacterium. Salmonella is often found in raw egg or poultry. It typically presents with gastrointestinal discomfort, diarrhea, and fever. It can be treated with antibiotics, but rarely becomes serious unless it is present in the old, the young, or the immunocompromised.

When a patient has true "heartburn," their heart is not actually the problem; they are suffering from Gastroesophageal Reflux Disease (GERD), also known as acid reflux. In this condition, acidic gastric contents inappropriately travel back from the stomach into the esophagus due to the faulty function of which structure?

The correct answer is the lower esophageal sphincter. In "heartburn," a patient's lower esophageal sphincter, which separates the distal esophagus from the proximal stomach, transiently relaxes its tone, inappropriately allowing food/digestive contents that have been acidified for digestion in the stomach to travel backwards into the distal esophagus. In patients with normal lower esophageal sphincter tone, i.e. without GERD, digestive contents that have passed to the stomach remain in the stomach without traveling backwards and causing an acidic, burning sensation in the esophagus.
The other answers are incorrect for the following reasons:
The epiglottis prevents food from being swallowed into the airway by closing off the airway temporarily during swallowing. It does not separate the esophagus from the stomach.
The upper esophageal sphincter is located proximally in the esophagus and opens to allow food to enter the esophagus from the pharynx. It does not separate the esophagus from the stomach.
The ileocecal valve is located distally in the small intestine, separating the ileum from the cecum of the colon. It functions to prevent colo-ileal reflux, but not gastro-esophageal reflux.
The left mainstem bronchus does not play any role in digestion of food or acid reflux, as it is part of the more distal respiratory tract.

Gout is a rheumatic disease that features monosodium urate crystals in tissue as the result of excess levels of uric acid in the blood stream. This can be caused by over or under excretion of uric acid. Gout can be both acute or chronic. Obesity, alcohol consumption, meat-rich diets, and poor kidney function are all risk factors. Ebola is an infectious virus that causes hemorrhagic fever. Asthma is a form of COPD (the other is chronic bronchitis), and is characterized by bronchoconstriction, causing difficulty breathing, especially when exhaling.

Hypernatremia. A pathological heart, is a heart that is not functioning properly. The kidneys rely heavily upon the heart for their perfusion and alteration to their perfusion will cause the activation of the renin-angiotensin-aldosterone system (RAAS). Thus, a pathological heart, which cannot adequately perfuse the kidneys with blood, will lead to the activation of the RAAS, causing hypernatremia (from increased aldosterone levels).
