Shade in the medicine cup to the nearest measurable individual or divided dose. 20 Mi 1 TSP S MLExplanation / Answer
Safe dose : For children above eight years, and below 100 pounds the dose is 2mg/ lb of body weight daily divided into two doses on first day.
Child’s actual weight in pounds : The child’s weight is 88.18 lbs (since 1 kg is 2.20 lbs)
Safe dose for child of this weight : The safe dose is 88.18 lb *2 mg/lb = 176.36 mg per day divided into two doses or it can be written as 88.18 mg po bid
Decision : subtherapeutic, safe or unsafe order
Since the prescription says 100 mg po bid it means 100 mg of medicine must be taken orally twice a day which is greater than the safe dose of 88.18 mg po bid.
Therefore it is an unsafe order.
How many ml should the nurse prepare if she were to give the ordered dose?
The syrup contains 50 mg/ 5 ml which is equivalent to 10 mg/ ml.
For the ordered dose of 100 mg the nurse has to prepare ( 10 mg in 1 ml therefore (10*10= 100 mg in 10 ml) 10 ml (2 TSP) of medicine.
