Thyroid disorders include structural and functional abnormalities, cysts, nodules, cancer and overactive or under-active thyroid. Which of the following is a risk factor of thyroid disorders?

You are in clinic working with an older patient reviewing their medications.  You are concerned about polypharmacy issues and are working with this patient on reducing doses or stopping any medications that may be causing harm or no longer benefit this patient.    Health care providers should consider patient/caregiver perspectives on goals of therapy.  They need to include views on medications and chronic conditions, preferences and priorities regarding prescribing to slow disease progression, prevent health decline, and address symptoms. Which of the following is NOT a true statement regarding polypharmacy?  

As the size of coarse aggregate increases, the roughness of the crack increases. This allows higher shear stresses to be transferred across the crack.

If φVc = 43 kip and Vu = 54 kip, are stirrups required?

Compute φVn for the cross section shown. Assume f’c = 4,000 psi, fyt = 60,000 psi, b = 10 in., d = 26 in., and that there are four No. 7 longitudinal tension bars and No. 4 stirrups at 8 in. o.c.

Compute φVn for the cross section shown. Assume f’c = 4,000 psi, fyt = 40,000 psi, d = 22 in., w = 16.5 in., t = 4 in., and that there are four No. 8 longitudinal tension bars and No. 3 stirrups at 6 in. o.c.

For a beam with stirrup hooks, the free end of the bar must extend at least _____ from the hook. Assume b1 = 35 in., b2 = 15 in., d1 = 6 in., d2 = 27 in., and that there are three No. 6 longitudinal tension bars and No. 4 stirrups at 9 in. o.c. The stirrup hooks are 90°.
