Resistivity: You are given a copper bar of dimensions 3 cm × 5 cm × 8 cm and asked to attach leads to it in order to make a resistor. (3 points each)(a) If you want to achieve the SMALLEST possible resistance, you should attach the leads to the opposite faces that measureA) 3 cm × 5 cm.B) 3 cm × 8 cm.C) 5 cm × 8 cm.D) Any pair of faces produces the same resistance.(b)  If you want to achieve the LARGEST possible resistance, you should attach the leads to the opposite faces that measureA) 3 cm × 5 cm.B) 3 cm × 8 cm.C) 5 cm × 8 cm.D) Any pair of faces produces the same resistance.

A patient with an IBW of 70 kg is on CPAP/PSV mode with the following settings below. The patient is awake, alert, and following commands and breathing comfortably. Pressure Support=5FiO2=50%Peep=5Flow Trigger= 2E sense= 25%Patient Data listed below:Spontaneous Respiratory Rate=18Spontaneous VT= 430 mlsVe= 7.74 L/minABG Values:pH=7.40PaCO2=40PaO2=120HCO3=24Based on the information above, what changes, if any, need to be done to improve the patient’s ABG?

True or False: Your patient is a female who has an IBW of 80 kg just successfully completed a 30 minute SBT trial on CPAP/PSV mode and the ABG results came back normal. After the SBT trial, the physician asks for you to obtain pulmonary mechanics from the patient. Below are the results NIF= -30 cm H2OVC= 1200 mlsRSBI=106Cuff Leak= YesSpontaneous Respiratory Rate=25The physician states that this patient is ready for extubation. Based on the results, is this statement true or false?
