A rectangular beam has a cross section of b = 18 in., h = 28 in., and d = 25.5 in. It is reinforced with four No. 5 Grade 60 bars. The concrete strength is 6,400 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the neutral axis location of the cracked beam (measured from the top of the beam).

Tied columns are less ductile than spiral columns, giving tied columns a lower strength-reduction factor.

The nurse is performing medication checks and realizes that some of the medications require the pre-administration assessment of heart rate. Which medication listed has a negative chronotropic effect and would require the nurse to know the heart rate prior to administration? SELECT ALL THAT APPLY

A rectangular beam has a cross section of b = 18 in., h = 28 in., and d = 25.5 in. It is reinforced with two No. 7 Grade 60 bars. The concrete strength is 9,400 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the gross moment of inertia, Ig, for the beam.

A rectangular beam has a cross section of b = 14 in., h = 24 in., and d = 21.5 in. It is reinforced with three No. 6 Grade 60 bars. The concrete strength is 9,400 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the cracked moment of inertia, Icr. The neutral axis location of the cracked beam (measured from the top of the beam) is 4.1442 in.

A rectangular beam with cross section b = 14 in., h = 26 in., and d = 23.5 in. supports a total factored uniform load of 3.10 kips/ft, including its own dead load. The beam is simply supported with a 23-ft span. It is reinforced with four No. 8 Grade 60 bars, two 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 3,300 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 four bars is φMn = 299.8 kip-ft, and the strength of the remaining two bars is φMn = 158.5 kip-ft. Determine the distance from the support to the theoretical cutoff point (i.e. disregard ACI 318-14 Section 9.7.3.3).

The nurse is caring for a client who has had a prescription changed from warfarin (Coumadin) to apixaban (Eliquis). The patient asks the nurse what test should be ordered to monitor the therapy of this medication. What is the best response by the nurse?

A client calls a clinic where he was prescribed an antidepressant 2 weeks earlier. The client reports no relief from the depression but has experienced dry mouth and constipation. Which antidepressant was most likely prescribed?

The fatigue strength of concrete is not sensitive to stress concentrations.
