Answer to Question 1

A
Feedback:
Trihexyphenidyl (Artane) is given 1 to 2 mg orally daily initially and then titrated up to 6 to 10 mg/d with a maximum of up to 15 mg/d to control symptoms. Trihexyphenidyl is an adjunctive therapy to levodopa in treatment of parkinsonism but it can be used alone for the control of drug-induced extrapyramidal disorders.

Answer to Question 2

A
Feedback:
The patient is receiving 500 mL over 4 hours. To determine how much fluid is infusing per hour = 500 mL 4 = 125 . In addition to the 125 mL of IV solution, the patient also receives 50 mL of gentamicin during the 02:00 to 03:00 hour. 125 mL + 50 mL = 175 total mL of fluid received during this hour.
