i think we r unable to get to final decision........

1)3) patients with recurrent bacteriuria should be placed on suppressive therapy..
2)a.draw blood for CBC, BUN, and electrolytes, and start intravenous fluids
Cow's milk .Cow's milk shouldn't be started before one year old.Cow's milk has higher renal solute load which can damage the kidney.it also increas the incidence of iron deficiency anemia.
3)b..because it is more associated with dcrease systemic blood flow.

4)Criteria for positive test :
Sciatic Pain before 70 degrees ,Aggravation of pain dorsiflexion of the foot and
Relief of pain by knee flexion
the patient physical finding is Crossed pain into opposite leg which
Indicates severe impingement and
Almost always due to a large disk herniation .IT IS NOT MORE SPECIFICE.

so it is A
