Question

I. The doctor orders NS 0.9% 100mL to be infused over 4 hours. The drop factor is 60gtt/ml. Calculate the gtt/min. Round your answer to the nearest whole number. Label correctly (25gtt/min) 2. The physician orders a low molecular weight Heparin dose of 0.5mg/kg. The label reads low molecular weight Heparin 40 mg/ml many ml wi the nearest tenth. Label correctly . The client's weight is 115lbs. How Il the nurse administer? Round your answer to (0.7ml) 3. The nurse practitioner prescribes I buprophen 400mg po every 6 hours. The pharmacy has available 200mg tablets. How many tablets will the nurse administer? Round to the nearest tenth, if applicable (2tabs po every 6 hours) 4. The primary care provider orders lactated ringer's fluids 1000mL to be infused over 25 hours. Calculate for mL/Hr Round your answer to the nearest whole number. (40ml/hr)

Answer 1

1) The volume of 0.9% NS to be infused over 4 hours is 100ml

The volume of NS to be infused in one minute is 100/(4*60) ml = 0.42ml

Drop factor is 60 gtt/ml

Drop factor for 0.42ml is = (0.42*60)/1, that is 25

The required gtt/min is 25

2) weight of client is 115 pounds which is 115/2.2 kgs = 52.3 kg

Dosage of low molecular weight Heparin prescribed is 0.5mg/kg. Total heparin required is 0.5*52.3 = 26

Concentration of the drug is 40 mg/ml

The required volume to be given is = (1*26)/40ml which is 0.7 ml

The required volume to be given is 0.7ml.

3)The prescribed dose of ibuprofen is 400 mg per every 6 hrs

The dosage of available tablets is 200 mg. So it takes 2 tablets to form the required dosage of 400mg.

Therefore the number of tablets the nurse has to administer for every 6 hours is 2.

4) The rate at which the lactated ringer’s fluid  has to be infused is 1000ml in 25hours.

The amount of fluid that has to be infused in one hour = 1000/25 ml that is 40ml

So the rate at which the lactated ringer’s fluid has to be administered is 40ml/hr.

Hope this helps you out. Feel free to give your feedback and if you want even more elaborate explanation. Thank you and have a nice day.
