The patient says she has been having episodes of diarrhea, which she attributes to laxatives she takes regularly to keep her weight down. She also says she has not had her period yet. The patients mother adds that the patient has been underperforming at school and acting very strangely at home. Her current BMI is 16.8 kgm2. On physical examination, the skin on her limbs and around her neck is inflamed and erythematous. Her tongue is bright red and smooth. She states that over the last 2 weeks, she has been eating nothing but small portions of fruit. She is diagnosed with a vitamin deficiency. Which of the following statements is true about the vitamin most likely deficient in this patient?? A: It is derived from tyrosine, B: Synthesis requires vitamin B1 and B6, C: It is used to treat hypertension, D: Synthesis requires vitamin B2 and B6, E: It increases the GI absorption of iron,  <response>: Based on the information provided in the question stem, this is a case of a 17-year-old girl with rapid weight loss, diarrhea, amenorrhea, poor school performance, strange behavior, low BMI, inflamed and erythematous skin, bright red tongue, and a fruit-only diet over the past 2 weeks. She has been diagnosed with a vitamin deficiency. The key findings pointing towards the likely deficient vitamin are: - Rapid weight loss, diarrhea, amenorrhea, inflamed skin, and fruit-only diet suggest malnutrition.- Bright red, smooth tongue suggests vitamin B2 riboflavin deficiency. - Strange behavior suggests vitamin B1 thiamine deficiency.- Vitamin C and iron deficiencies are less likely given the normal diet until 2 weeks ago. So the vitamin deficiency is most likely vitamin B2 or B1.D: Synthesis requires vitamin B2 and B6
