Which of the following is likely to cause hyperthermia as a toxic manifestation?

A 12 yr old male with AML is hospitalized for intensification of chemotherapy. He is started on Bactrim, acyclovir and fluconazole prophylaxis. He develops prolonged fevers >10 days with an increased oxygen requirement. CXR demonstrates low lung volumes. He is receiving Vancomycin and Zosyn and FARVPP is negative. What is the next BEST test to perform for diagnostics?

A non-invasive test that can be ordered to confirm a suspicion of Neuroblastoma is:

How many mL of a 0.2 M NaOH solution are required to completely neutralize 34.2 mL of a 0.2 M HCl solution?  

In the balanced reaction below, 115 g of Al reaction with 220 g Fe2O3, calculate the mass of Al2O3 2Al(s) + Fe2O3(aq)

What volume (in mL) of 0.167 M HCl is required to neutralize 3.46 g Mg(OH)2?  

A reaction occurs in a closed container that releases 950 J of heat into the surroundings. As the reaction proceeds, the product falls out as a solid and causes the container to contract. This results in the surroundings performing 220 J of work on the system. What is the change in internal energy (in kJ)?

A 43.5 g sample of iron (specific heat capacity = 0.444 J/g °C) is heated to 89.4°C and placed into a calorimeter holding 73.4 g water at a temperature of 23.8°C. Assuming no heat loss to the calorimeter, what will be the final temperature reached in the calorimeter?  

Cerebellum measurement equals the number of weeks of pregnancy (2nd trimester)?

Given the thermochemical equation for photosynthesis, 6H2O(l) + 6CO2(g)
