You have just started working in an Urgent Care Clinic as a nurse. Mom brings in her 3 year old little boy, Brandon. Mom states that Brandon has been having fever up to 104F and he isn't eating or drinking anything because he feels very sick to his stomach, not to mention crabby! He's also been pulling a lot at his right ear and sounds congested. At the last well visit with the Pediatrician (about 2 weeks ago), Mom states that Brandon weighed 32 pounds. On exam today, his weight is 12.5 kg. Additionally his eyes are darkened and sunken, his mouth is dry with some white crusting around the lips. His temperature is 39C, other vitals signs are normal. Though he looks ill he appears to be medically stable. The doctor rushes in, quickly exams Brandon, diagnoses him with otitis media and then barks off orders to you that you then need to convey accurately to Mom. The orders include: push fluids, ibuprofen 10mg/kg every 6 hours if temp > 38C, and begin taking a 10-day course of…
Many common materials that we ingest, though quite safe in reasonable quantities, become toxic when taken in very large doses. A measure of toxicity is the LD50 value (Lethal Dose, 50%). It is the quantity of material, expressed in mg of material per kg of subject-body-weight that, if administered to a population of subjects, would cause 50% of the population to die. The LD50 value for FD&C Red Dye No. 40 is >10,000 mg/kg in rats. Assume that the LD50 value for humans is the same as for rats. Calculate the number of mg of Allura Red present in an 8 fluid ounce glass of the beverage you used in this lab. Assume that the concentration of Allura Red in the beverage is 0.000054 M. The molar mass of Allura Red is 496.42 grams/mol 1 fl oz = 29.5735 mL Do not include units with your answer.
Can you write the answer in a way that fills the empty cells, please? Thank you.
