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?

Determine the epoxy modification factor, ψe, for a rectangular beam with b = 17 in. and d = 22 in., five epoxy-coated No. 8 Grade 60 tension-reinforcement bars placed in the top of the beam, and No. 3 Grade 40 stirrups located every 10 in. along the span. Assume 4,000-psi normal-weight concrete and a clear cover of 2 in.

A rectangular beam with cross section b = 16 in., h = 28 in., and d = 25.5 in. supports a total factored uniform load of 1.40 kips/ft, including its own dead load. The beam is simply supported with a 24-ft span. It is reinforced with five No. 5 Grade 60 bars, three of which are cutoff between midspan and the support and two of which extend 10 in. past the centers of the supports. The concrete strength is 5,400 psi (normal weight). The beam has Grade 60 No. 3 stirrups satisfying ACI 318-14 Sections 9.7.6.2.2 and 9.6.3.3. The strength of the five bars is φMn = 173.4 kip-ft, and the strength of the remaining two bars is φMn = 70.44 kip-ft. Determine the distance from the support to the theoretical cutoff point (i.e. disregard ACI 318-14 Section 9.7.3.3).
