Consider a 11-unit office building where each unit contains one A/C rated at single phase 5hp 200V The full load current for one would be: One motor load would then be: The total load for all these A/C would be:

Consider a branch circuit for 14kW fixed electric space heater w/ 5.4 Amp blower motor 208 Volt 3-phase What is an adequate overcurrent protection size rating?

Consider the following Transformer Which is a 5 kVA transformer used to step down 480 to 120 volts to supply a single-phase two-wire circuit  The calculated primary full load current for this transformer is The maximum primary over current would be The calculated secondary full load current for this transformer is The maximum secondary over current would be

Consider the following three-phase short circuit: With  A. 1000 kVA Transformer with 480V, 3Ph, 3.5% Z B. 25′ – 500kcm copper, 3 single conductor 6 per phase service entrance in steel conduit C. 2000 A switch with 2000 A fuse x1 Fault X1 D. 400 A switch with 400 A fuse E. 50′ – 500kcm copper, 3 single conductor feeder cable in steel conduit x2 Fault X2   Using Point-to-Point calculation (using the given impedance at 100%) The total current for short circuit sym RMS at Fault X1 is The total current for short circuit sym RMS at Fault X2 is

You’re caring for a group of patients on a telemetry floor. Who should be assessed first?Patients:A patient with a potassium level of 5.9 mEq/L and no cardiac symptoms.A patient with chest pain rated 7/10 who is waiting on labs.A patient with atrial fibrillation who has a heart rate of 120 but is alert and oriented.A patient recovering from a syncopal episode who has stable vitals.Select the patient who requires priority assessment and explain why, considering potential life-threatening complications. (2 pts)

You are the nurse on a surgical unit. Which of the following patients should you prioritize for assessment and intervention?Patients:A post-op patient who has not voided in 8 hours.A patient who is 2 days post-op with a surgical dressing saturated in serosanguinous fluid.A newly admitted patient complaining of throat tightness and itching after the first dose of an IV antibiotic.A patient who is requesting help to the bathroom and is a fall risk.Determine which patient needs immediate assessment and explain the rationale using the ABCs and safety principles. (2 pts)
