1). Nebcin 35 mg IV every 8 hrs. for a child who weighs 14 kg. The recommended dosage for pediatrics is 2 -2.5mg / kg / dose.

(A) What is the recommended minimum dosage for this child? How many mg /dose?

(B) What is the maximum recommended dosage for this child? How many mg / dose?

(C) Is the ordered dose safe?

2).The flow rate (ml/hr.) for 1 Liter is 80ml/hr. It started at 1000. Calculate the infusion time and completion time in traditional time and military time?

Infusion Time

Military Time

Traditional Time

3). Order: V-cillin K 300,000 Units PO four times a day. It is supplied as: V-cillin K 200,000 units/ 5ml. How many mLs should be administered?

4).The child has an order for Thyroxine 0.2 g PO daily. Thyroxine is available in 100mg tablets. How many tablets will the nurse administer?

Expert Solution

1) a) Recommended minimum dosage(mg/dose) for this child.

Recommended minimum dose for pediatrics = 2 mg/kg/dose.

Weight of the child = 14 kg.

So

Recommended minimum dose for this child = 2 * 14

= 26 mg/dose.

b) Recommended maximum dosage(mg/dose) for this child.

Recommended maximum dose for pediatrics = 2.5 mg.

Weight of the child = 14 kg.

So

Recommeded maximum dose for this child = 2.5 * 14

= 35 mg/dose.

c) Ordered dose = 35 mg.

Recommeded dose = 26 mg to 35 mg.

So

* Ordered dose is SAFE for this child.

2) Calculation of infusion time.

ml/hr = Volume(ml)/Infusion time(hr).

Infusion time(hr) = Volume(ml)/ml/hr.

Here

Volume(ml) = 1000 ml (1L).

ml/hr = 80 ml/hr.

Infusion time(hr) = 1000/80

= 12.5 hr.

*Completion time in military time.

Completion time = starting time + 12.5 hr.

= 1000 + 12.5 hr(12 hr 30 min)

= 2230.

*Completion time in traditional time.

Completion time = Starting time + 12.5 hr

= 10.00 am + 12.5 hr (12 hr 30 min)

= 10.30 pm.

3) Calculation of volume(ml).

Volume(ml) = Desired dose/Dose in hand *Quantity.

Here

Desired dose = 300000 unit.

Dose in hand = 200000 unit.

Quantity = 5 ml.

As per above formula

Volume(ml) = 300000/200000 * 5

= 1.5 * 5

= 7.5 ml.

4) Calculation of number of tablets required.

Ordered dose = 0.2 g.

Converet g to mg for calculation

1 g = 1000 mg.

Ordered dose = 0.2 * 1000

= 200 mg.

Available dose = 100 mg/tablet.

As per above formula

Number of tablets required = Ordered dose/Available dose.

= 200/100

= 2 tablets.
