After the week of treatment all students are given the same test. What is the Control Group? Select the best answer. The amount (250 mg). Time. The 50 students fed the placebo. The test scores. The students. The 50 students fed the brainium. The type of pill (brainium or placebo)

- You have an order for 1 gram of Cefazolin in D5W 100 ml. You have added 5 ml of sterile water to the 1 gram vial to reconstitute powder. However the recommended manufacturer’s diluent amount is 10 ml of sterile water for a final concentration of 100 mg/ml. How would reconstituting the vial with 5 mls affect the concentration and the final calculated dose. Please answer with explanation ASAP. I will really upvote. ThanksA glucose monitor is an instrument that diabetics use to check their blood sugar. To use it, you insert a 'test strip' into the monitor and apply blood to it, then the blood is sucked into the instrument and the concentration of the sugars in the blood are measured. Like most instruments, it isn't 100% accurate 100% of the time. The informational pamphlet includued with the test strips say that a sample with a concentration of 7.2 mg/ml will give a reading with a standard deviation of 0.2 mg/ml. This means that when measured, a sample of blood with a 7.2 mg/ml glucose concentration will give a reading between mg/ml % of the time. mg/ml andDr Janis toboggan has two patients who were admitted to her hospital with covid-19. And she gave them both the drug known as remdesivir. Patient A got better and was released from the hospital in two days, but it took a week for patient b to recover and be sent home. That’s interesting though dr toboggan. “Why did the drug work differently in the two patients? Remedesivir seemed to help one patient but not the other. Maybe the drug speeds up recovery but the patients had different levels of infection. Or, maybe remdesvir didn’t have any effect on recovery, and the patients were just at a different places in their infections by the Novel corona virus. To find which hypothesis was a better explanation her data, Dr To boggan applies a little deductive reading. “What if I set up a situation where I have two patients at the same point in their infection and I give one the drug and one not? If remedesivir speeds up recovery, then the one with the drug will recover faster. But if…

- When you purchase drugs, there are many doses in the container. No one wants to drive to the store each time they have a headache! You can calculate the number of doses per container using the following formula: number of tablet per container /tablets per dose (formula) Calculate the number of doses per container for Brand X. Do not include a unit in your answer. Brand X antacid: 2 tablets / 500 mg dose 40 tablets / container Cost: $3.75 / container125 mg of solid drug is placed in solution. Over time the drug dissolves. The amount of undissolved drug in mg was monitored as a function of time in minutes. The data was graphed with the following results: Amount of drug remaining vs. time: best fit is y = -11.4x + 125 R2 = 0.990 ln(Amount of drug remaining) vs. time: best fit is y = -0.114x + 4.84 R2 = 0.976 How much drug (in mg) remains after 5 minutes?Which of the phi/psi angles would be violating a ramachandran plot? Select all that apply: Phi= 90; Psi=-120 Phi= -120; Psi=120 Phi= 0; Psi=0 Phi= -90; Psi=-60 Phi= 120; Psi=-120
