Did I calculate these three problems correctly using the dimensional analysis method thank you

DA client weighs 208 lbs and is to recieve Zovirax 12 mg/kg P.O. twicece day The Zovirax is avaliable is loong/2mL 708 lbs = 1,134.5mg per clase Give: ? my per close my 12ms. hello" Give: ? mL per 24hrs 2 220 = 22.09 = 22.7mL X2 F43.4 mL per 24hrs Order: Dilantin Suspension ong by mouth daily Aucliable: Dilantin Suspension 125mg (85 mL Giver? fluid cances per day Gives? my per day OZ= 5 om E7 oz perday) mg = logom, overs = qorong perday 102 SSmly A Client weighs 5416s is to recrec Tobramycin 2 mg/kg IM qind (4x's day) Avaliable: Tobramycin 10mg/mL Give ? mL per dose me=img en lky suilos = 1,1982 El me perdose/ Give? mg in 24hrs mg = Zong, I ka sulys 1,0m2 = 491.81 491.8 mg x4 = 1,967.2 maferday

I've already done the math i just need it to be checked incase i did it wrong. These are to be solved using the dimensional analysis method (conversions)

Answer 1

1.

A client weights 208lbs (94.34kg)

Ordered dose Zovirax 12mg/kg PO twice a day.

Available quantity 100mg/2ml

So, you need to give 1132mg per dose

94.34kg x 12mg/kg = 1132mg

The patient will receive total of 2 doses in a day.

I.e he will receive 2264 mg in a day   

1132mg x 2dose day = 2264mg/day

Available quantity 100mg/2ml I.e 50mg/ml

/day

2264mg + 50mg/ml = 45.28ml

The patient will receive 45ml of the drug in a day.

2.

Dilantin suspension 0.4 g PO (400 mg po)

Available quantity 125mg/35ml

3.57mg of drug per ml

125mg + 35ml = 3.57mg/ml

So, You will give 112 ml (3.7 us fluid ounces per day)

400mg + 3.57mg/ml = 112ml

You will give 400 mg per day

3.

A client weights 54lbs(24.49kg)

Order dose tobramycin 2mg/kg IM

Available tobramycin 10mg/ml

The patient will receive 49mg of the drug

24.49kg x 2mg/kg = 48.98mg

The patient will receive 4.9ml of drug

49mg + 10mg/ml = 4.9ml
