Explanation / Answer

Drugs that are unstable in liquid form are manufactured in powder form. These medications must be
converted to liquid form (i.e. reconstituted) before they can be administered to patients. Information
about the amount and type of solution (i.e. diluent) needed to reconstitute the drug can usually be
found on the drug container label, in the manufacturer’s package insert and/or in the drug monograph
(usually found in a facility’s drug manual) (we recommend using the drug monograph whenever
possible). Examples of diluents include:
• sterile water for injection
• bacteriostatic water for injection
• 0.9% sodium chloride for injection
Strict aseptic technique must be used when reconstituting medications. Once the drug is reconstituted,
any unused amount must be labeled and stored appropriately (either at room temperature or in the
refrigerator). Take special notice of how long the drug is stable.
Using the following Basic Formula can help to simplify your drug calculations:
D/Hx V = amount to give

D = desired dose (i.e. the drug dose ordered by the physician)
H = on-hand dose (i.e. the drug dose on the label of the drug container)
V = vehicle (i.e. the form and amount in which the drug comes)

1. Answer: the IM is not used since physician prescribed 500mg dose of IV for every 08 hours:
so comming to the product availability :

750mg vial for whihc 8.3 (ml of water added) which gives solution of 220mg/ml in this case:

required dose of drug/hand on dose*1=amount to give

if we apply 500/90=5.55=5.56(rounded)
5.56 require to add to 8.3 like wise if we calculate for

7.5 mg/ml 500mg/7.5= 66.66ml dilutent require to add to 7.5mg/ml

in case of 15mg/ml 500/15=33.33 ml diluent require to add to 15mg/ml

Second concept:

1.Evaluate baseline and ongoing laboratory tests;

2.use an idependent double check when preparing dose

these were the measures taken for heparin administrstion
