A transient ischemic attack (TIA) is an acute neurological event in which all signs and symptoms, that may include numbness, weakness, flaccidity, visual changes, ataxia, or dysarthria, resolve within minutes to 24 hours after onset. When caring for a patient in the primary care setting, the APRN should consider that:

A beam has dimensions of b = 14 in., h = 26 in., d’ = 2.5 in., and d = 23.5 in. It is reinforced with 2 No. 5 bars on the compression side and 4 No. 8 bars on the tension side. The concrete strength is 2,800 psi, and the yield strength of the reinforcement is 60,000 psi. For the results given below, determine the strength Mn for this beam.a = 4.828 in. (depth of concrete stress block)Cc = 159.4 kips (compressive force in concrete)Cs = 30.2 kips (compressive force in steel)T = 189.6 kips (tensile force in steel)
