You have just discovered an unusual new species that has neurons with a resting membrane potential of +50 mV! It seems to accomplish this with only Na+/K+ pumps, Na+ Leak channels and K+ Leak channels in the cell membrane. The ion concentrations inside and outside of the cell are at typical values for a mammalian neuron. Which of these could explain the positive resting membrane potential?

A patient who is hemorrhaging has pale mucous membranes, blood pressure 92/52 mm Hg, pulse 160 beats/minute, and respirations 30/minute. The patient is receiving IV fluids at 150 mL/hour, has a blood transfusion infusing, and is being provided oxygen via a mask. What should the nurse recognize as the most likely cause of the patient’s respiratory rate?

A nerve conduction velocity (NCV) study is performed by researchers studying Charcot-Marie-Tooth syndrome in mice. Below are the results from one animal. The short distance measured for the study is 34 mm and the long distance is 67 mm. The average conduction time for the short distance was 0.5 ms and the average long distance conduction time was 1.2 ms. What is the nerve conduction velocity (NCV) for this data?

The nurse in an emergency department is helping triage victims of an explosion. Rank, in order from 1 to 5, the following patients according to their need for priority treatment according to disaster response protocols and mass casualty event triage. 1. A 15-year-old with a laceration to the foot that is bleeding slightly2. A 36-year-old who has no pulse or respirations and has an open head injury3. A 62-year-old with a distended abdomen who reports severe abdominal pain4. A 5-year-old with a suspected fracture of the humerus5. A 58-year-old woman with a full-thickness burn to the bilateral lower extremities
