Question: 1 of 25 Time Elapsed 00 00 27 FLAG A nurse is preparing to administer erythromycin ethylsuccinate 50 mgkg/day PO divided in equal deses every 6 hr to a toddler who weighs 32 lb Available is erythromycin ethylsuccinate suspension 200 mg/s mL. How many mi should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.) mL

Answer 1

question 1:

Dose of Erythromycin ethylsuccinate = 50mg/kg/day in four doses

Weight of toddler =32 lb =14.54 Kg

Dose per day for the child = 14.54 ×50 = 727.27 mg

Each dose will be 727.2/ 4 = 181.8 mg

Dose of the medicine available = 200mg/5ml

Amount of the medicine to be given in each dose =   

dose prescribedx Amount in hana dose in hand

                                                       =    = 4.54 ml

181.8x5 200

So the amount to be given for the child is 4.5 ml every 6 hourly

question 3:

Weight of client = 120 lb = 54.54 Kg

Dose of Phenytoin = 15mg/kg/day tds

The dose/ day for the client = 54.54 × 15 = 818.1 mg

Each dose will be 818/3 = 272.7 , Approximately 273 mg

Dose available = 125mg/5ml

How many ml is needed for each dose =                                                                                               

dose prescribedx Amount in hana dose in hand

                                                            =

273x10.9 125

The amount to be administered per dose is 11 ml

question 4:

Weight of infant = 5.5 Kg

Dose of Amoxycillin = 30mg/kg/day in two doses

Dose to be administered to the baby in a day = 5.5 × 30 =    165mg

So each dose will be = 165/2 =82.5 mg

Dose available =125mg/5ml

Amount to be administered =

dose prescribedx Amount in hana dose in hand

                                                 = = 3.3 ml

82.5x5 125

The baby has to be given 3.3 ml of the Amoxycillin every 12 hrs.
