Question

Mr. Riddle has been diagnosed with psychosis. He frequently has auditory hallucinations, stating he hears people referring to him as "Lord". He also experiences delusions of grandeur, where he describes ruling the world and insisting that he "can live forever". The physician has ordered this patient to receive Haloperidol Decanoate 1.2 mg/kg intramuscularly once every month to control his psychotic episodes. Mr. Riddle weighs 198 pounds. Calculate his dose and write the sig for his prescription. (Round the dose to the nearest whole number) Pt: Tom Riddle Rx: Haloperidol Decanoate Sig: Inject mg Refills: 11

Answer 1

Weight of Mr.Riddle = 198 pounds = 198/2.2 = 90 kg

Prescribed order of Haloperiodol Decanoate = 1.2 mg/kg IM once every month

Prescribed order of Haloperiodol Decanoate for Mr.Riddle who is 90 kg = 1.2 mgx 90 =108 mg

Inject 108 mg IM once every month for Mr.Riddle.
