NSG 5003 Midterm exam 2023 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. Potass...

Following A. Electrolyte inephrine (Levophed) administration, it is essential to the nurse to assess: A. Electrolyte status. B. Color and temperature of toes and fingers. C. Capillary refill. D. Ventricular arrhythmias. Correct Answer: B. Color and temperature of toes and fingers. Because decreased perfusion is a side effect of norepinephrine (Levophed), the nurse must check circulation frequently. Vasoconstriction secondary to alpha1 stimulation can result in reflex bradycardia via the barorece...
