A 29-year-old female is hospitalized 1 day after an endoscopic retrograde cholangiopancreatography (ERCP) because of vomiting, weakness, and severe abdominal pain. Physical examination findings include abdominal tenderness and diminished bowel sounds. A CT scan demonstrates fluid around the pancreas. Serum levels of which of the following are likely to be low in this patient?

BTriglycerides
CCalcium
DGlucose
ELipase
A 55-year-old woman presents with fatigue and flu-like symptoms. She says her symptoms started 5 days ago with a low-grade fever and myalgia, which have not improved. For the past 4 days, she has also had chills, sore throat, and rhinorrhea. She works as a kindergarten teacher and says several children in her class have had similar symptoms. Her past medical history is significant for depression managed with escitalopram, and dysmenorrhea. A review of systems is significant for general fatigue for the past 5 months. Her vital signs include: temperature 38.5°C (101.3°F), pulse 99/min, blood pressure 115/75 mm Hg, and respiratory rate 22/min. Physical examination reveals pallor of the mucous membranes. Initial laboratory findings are significant for the following: Hematocrit 24.5% Hemoglobin 11.0 g/dL Platelet Count 215,000/mm3 Mean corpuscular volume (MCV) 82 fL Red cell distribution width (RDW) 10.5% Which of the following is the best next diagnostic test in this patient?
ASerum iron level
BSerum ferritin level
CReticulocyte count
DHemoglobin electrophoresis
ESerum folate level
A 29-year-old woman presents with a 2-hour history of sudden onset of severe mid-epigastric pain. The pain radiates to the back, and is not relieved by over-the-counter antacids. The patient also complains of profuse vomiting. The patient’s medical history is negative for similar symptoms. She consumes 3–4 alcoholic drinks daily. The blood pressure is 80/40 mm Hg and the heart rate is 105/min. Examination of the lungs reveals bibasilar crackles. Abdominal examination reveals diffuse tenderness involving the entire abdomen, marked guarding, rigidity, and reduced bowel sounds. The chest X-ray is normal. However, the abdominal CT scan reveals peritoneal fluid collection and diffuse pancreatic enlargement. The laboratory findings include: Aspartate aminotransferase 63 IU/L Alkaline phosphatase 204 IU/L Alanine aminotransferase 32 IU/L Serum amylase 500 IU/L (Normal: 25-125 IU/L) Serum lipase 1,140 IU/L (Normal: 0-160 IU/L) Serum calcium 2 mmol/L Which of the following cellular changes are most likely, based on the clinical and laboratory findings?
ALiquefactive necrosis
BDry gangrene
CCaseous necrosis
DCoagulative necrosis
EFat necrosis
