ATI RN MED-SURG PROCTORED EXAM 2023 (FULL EXAM) SOLVED CORRECTLY. 1. The nurse is preparing the discontinue long term TPN therapy for a client. The nurse should plan to discontinue the TPN gradually to reduce the risk of which of the following adverse effects? a. Hyperglycemia b. Diarrhea c. Constipation d. Hypoglycemia- You taper it off to avoid this!!! Rationale PDF p.298: Never abruptly stop TPN. Speeding up/slowing down the rate is contraindicated. An abrupt rate change can alter blo...

Combustible Liquid - Correct answer-A liquid with a flash point ABOVE 100F 12.5 - Correct answer-If the current flowing out from an electrical panel is 12.5 amps, and it then flows through an electrical load of 1500 watts, what is the amperage of the remaining current flow of the return circuit? 1000 - Correct answer-If a hair dryer draws 8.3amps (in a home with 120-volt service), what is the wattage? *Power (P) = current (I) x voltage (V) Watts = amps x volts 1987 - Correct answer-The y...

Rheobase - the lowest point on a strength duration curve at an infinitely long pulse duration Chronaxie time - the pulse width at twice the rheobase value. It approximates the most efficient stimulation pulse duration Charge (formula) - Charge= I(current) x T(time) Furman's formula - Energy(microjoules)= I(current)xV(voltage)xT(pulse width) Ohms law formula - Voltage(electromotive force)= I(current/flow of electrons) x R(resistance to current flow in ohms) Functional Refractory P...
