Ex Input:
Question: A drug with a seemingly monocompartmental distribution pattern is administered in the form of i.v. perfusion. at a constant speed of 20 mg / h for 48 h. Once the perfusion is finished, three blood samples are taken, which, when analyzed, allow the calculation of the primary parameters of the model Kel = 0.0495 h-1, concentration at the end of the perfusion (C48h) = 5,553 μg / mL, Vd = 66 L. At what time would the steady state be reached ?: 
 Options:  <1> 14 h. <2> 28 h. <3> 42 h. <4> 56 h. <5> 70 h.

Ex Output:
5
