- An IV infusion is to contain 40 mEq of potassium ion and 10 mEq of sodium ion in 500 mL of D5W.Using a 20% w/v potassium chloride injection (MW 74.5, valence of 1) and 0.45% sodium chlorideinjection (MW 58.5, valence of 1), how many milliliters of each should be added to the 500mL bag ofD5W to supply the required ions?How many mL of 3% sodium chloride will be needed to complete the following compound? Sodium Bicarbonate (E-value = 0.65) |4.2 grams Sodium Chloride gs to make isotonic for IV infusion Sterile Water for Injection ad 385The material to be heated is in a long, cylindrical tube, and is viscous enough that any flow inside the tube can be ignored, i.e. the heating is by conduction alone). Also, consider the glass of the tube to be very thin so its thermal resistance can be ignored. The tube diameter is 1 cm and the properties of the material are the same those of water, given by 0.64 W/m*K, 1000 kg/m3, and 4180 J/kg*K, for thermal conductivity, density, and specific heat, respectively. The water bath temperature is 65 °C, and the initial temperature of the material is 27 °C. Without the agitation of the water bath, the heat transfer coefficient can be considered to be 128 W/m2*K. Considering the tube to be a long cylinder, how long does it take for the coldest point to heat up to a temperature corresponding to 99% of the total possible temperature increase? If the surrounding how water is agitated using a stirrer, leading to a considerably large surface heat transfer coefficient, how long does it…

- A vial containing 400 mg hydrocortisone sodium succinate powder for injection is to be reconstituted to produce 8 mL of injection. What is the amount of Water for Injections, BP that should be added to the powder? The displacement volume of hydrocortisone sodium succinate is 0.05 mL/100 mg.A nurse wants to know the what volume of Water for Injection, BP to be added to a vial containing 500mg doxorubicin to produce an injection with a concentration of 2.5 mg/mL. The displacement volume of doxorubicin is 0.3 mL/10 mg.) The order is for 200 mg of drug to be administered IM. The directions on a vial containing 1 g of powder indicate that adding 7.2 mL of sterile water for injection will yield a concentration of 125 mg per 2mL. How many milliliters must you withdraw to obtain 200 mg of the drug? +) An IV solution is flowing at the rate of 30 gtt/min. What is the equivalent rate in mL/h if the drop factor is 60 gtt/mL?
