NSG 5003 Midterm (NSG 5003)

NSG 5003 Midterm QUESTIONS & ANSWERS What causes the rapid change in the resting membrane potential to initiate an action potential? Question 1 options: Potassium gates open and potassium rushes into the cell, changing the membrane potential from negative to positive Sodium gates open and sodium rushes into the cell, changing the membrane potential from negative to positive. Sodium gates close, allowing potassium into the cell to change the membrane potential from positive to negative. Potassium...

NSG 5003 Midterm Review Form of necrosis a/w TB? Most common cause of cellular injury? Acid- pH <7.35 Base- pH >7.45 Oxidative phosphorylation occurs in the mitochondria. Oxidative phosphorylation is the mechanism by which energy produced from carbs fats, and proteins is transferred to ATP. Hypotonic solution causes cellular swelling- D5W (dextrose in water), D5 1/2NS (5% dextrose and 0.45%NS), 1/2NS (0.45%NS), D5 1/4NS( 5% dextrose and 0.2%NS), 1/4NS (0.2%NS) Hypertonic solution cau...
