In neuroscience, the threshold potential is the critical level to which a membrane potential must be depolarized to initiate an action potential. Threshold potentials are necessary to regulate and propagate signaling in both the central nervous system (CNS) and the peripheral nervous system (PNS).
Most often, the threshold potential is a membrane potential value between –50 and –55 mV,[1] but can vary based upon several factors. A neuron's resting membrane potential (–70 mV) can be altered to either increase or decrease likelihood of reaching threshold via sodium and potassium ions. An influx of sodium into the cell through open, voltage-gated sodium channels can depolarize the membrane past threshold and thus excite it while an efflux of potassium or influx of chloride can hyperpolarize the cell and thus inhibit threshold from being reached.
<span>Answer:
We have following options to select the answer from:
1. The continuity of care is a problem.
2. The registered nurse doesn't spend enough time with the client.
3. The team leader needs to take time to delegate work.
4. The associate nurse cannot change a care plan without consulting the primary nurse.
The best answer choice is:
1. The continuity of care is a problem. This is the advantage because after the shift the continuity of the care of the nurse to the client or patient. Care is provided by the registered nurse to the client during a stay in a facility.</span>
