Expert Solution

1)Given, the flow rate of normal saline is 60ml/hour. So, for 500ml it takes 8.33 hours to complete.

So if the IV was started on monday 2000,It would be completed by tuesday 0430.

EXPLANATION:

Given that iv started at 2000 means at 8pm on monday.So,by adding 8.3 hours to it ,it will complete by the following day 4am also written as 0430.

2)Given that gentamycin 50mg should be given every 8 hourly(three times a day) and the child weighs 40 pounds which means 18.1Kgs.

The recommended dosage range is 6-7mg/kg/day in divided doses. So a child of 18kgs should receive 108-126mg in divided doses 8 hourly.

So, 50mg 8 hourly(three times a day) means 150mg/day(50*3) which is exceeding the upper limit.Hence, it is not a safe dose.

3)Given that 10mg phenobarbital should be given every 12 hours (2 times a day) and the child weighs 9 pounds(9 pounds = 4 Kgs).

The recommended dosage range is 3-5mg/kg/day administered every 12 hours. So, 12-20mg every 12 hours can be administered for a child weighing 9 pounds.

So, 10mg every 12 hours is a safe dose to be administered to this child.

4)Given,

Order/dose(D) - 20mEq

Available on hand(H) - 8mEq per 5 ml.so 1ml = 1.6mEq

so 1ml (X)= 1.6mEq(H)

So by using the formula

So,12.5ml should be administered to get 20mEq of kcl.

5)Given,

Dose ordered(D) = 1gm or 1000mg.

Available on hand (H) = 200mg per 1 tablet

X = 1

using the formula

So, the nurse should administer 5 tablets of zovirax 200mg.
