I did the test sorry if wrong
For a 2 year old patient who was severely dyspneic and now unresponsive and no longer breathing, you will instruct your EMT to insert an OPA and begin give positive pressure ventilations with a BVM with 100% O2 to the patient. Palpate for a pulse and if <10 seconds you cannot feel a pulse, you will begin chest compressions.
The good thing about respiratory codes in children is that they normally always code due to lack of oxygenation. Once they are finally re-oxygenated, they will typically come around with better vitals.
When neurons are not producing electrical signals we say that they are at resting phase: voltage across their membrane is called the resting membrane potential, or the resting potential.
This potential is determined by the concentration of ions (Na, K) across the membrane and by membrane permeability to each type of ion. While the ions move through channels down their gradients they lead to a separation of charge and that is what creates the resting potential.
The membrane of the neuron is much more permeable for K ions so the resting potential is close to the equilibrium potential of K+.
Answer:
Symbiosis is a close relationship between two species in which at least one species benefits. Mutualism is a symbiotic relationship in which both species benefit. Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected.
