1. The physician writes an order for Cipro 250mg BID x 3 days for a UTI. On hand you have 5 grams/100ml.

How many ml will you administer?

Answer:

Formula :

Volume required =    Strength required / Strength in hand   X Volume of stock / 1

  • Step 1 : Change gms to mg

                1 gm = 1000 mg

                5gm = 5000 mg

  • Step 2 : Apply formula

Volume required in ml = 250mg /5000 mg X 100 ml /1

  • Dose to be administer = 5 ml ( daily twice for 3 days).

----------------------------------------------------------------------------------------------------------------------------------------------------

2. A mixture contains Penicillin 250mg/5ml.

How many mg are in 15mls?

Answer:

Penicillin 250 mg in 5ml

  • Step 1 : 5 ml = 250 mg

                1ml=250mg / 5

                1ml = 50 mg.

  • Step 2 : mg in 15 ml

                1ml = 50mg

15ml = 15 X 50 mg

                =750 mg.

Therefore , 750 mg are in 15 mls.

3.For your paediatric patient, the physician orders Ampicillin 50mg/kg/day PO, divided into 6 hour doses. Your patient's weight is 22kg.  

a) What is the daily dose of Ampicillin for this patient?

The daily dose of Ampicillin is ______ mg for this patient.

b) How much Ampicillin will you administer every 6 hours?

I will administer _______ mg of Ampicillin every 6 hours

c) The Ampicillin is available in 250mg/ml. How many ml of Ampicillin would you administer per dose?

I will administer _______ mg of Ampicillin per dose.

Answer :

physician orders = Ampicillin 50mg/kg/day

patient's weight = 22 kg.

Ampicillin Available dose = 250 mg/ml

A ) Daily doses of ampicillin ?

  • Step 1 : 1 kg = 50 mg

22 kg = 22 x 50

22 kg = 1100 mg / day

So ,daily dose is 1100mg/day for this patient.

B) 4 times (6 hrs/day) = 1100 mg / 4

                                                = 275 mg

I will administer 275 mg of Ampicillin every 6 hours

C )           6 hrs = 4 times /day (1100 mg = 275 x 4 )

I will administer 275 mg of Ampicillin per dose.

In ml calculation :

1 ml = 250 mg

275 / 250 X 1 ml / ? = 0.5 ml

----------------------------------------------------------------------------------------------------------------------------------------------------

4.The physician writes an order for Vancomycin 1gm BID x 3 days.  

On hand you have 250mg/100ml.

How many ml will you administer per dose

Answer:

Vancomycin 1 gm BID X 3 days

On Hand 250 mg / 100ml.

Step 1 : 1 gm = 1000 mg BID (3Days)

Step 2 : 1000mg / 250 mg X 100 ml / 1

Per dose = 400 ml .

So I will administer 400 ml per dose .

----------------------------------------------------------------------------------------------------------------------------------------------------

5. Covert 62lbs into KG

Provide your answer to 2 decimal places.  Rounding is NOT required for this answer

Answer :

  • Convertion 62 lbs into KG.
  • 1 lbs = 0.453592 kg
  • 62 lbs = 62 X 0.453592

= 28.12 kg
