The movement of ions through their channels require a discharge of the capacitance.

Nesterboy [21]

Answer:

The answer to the question: The movement of ions through their channels require a discharge of the capacitance, is, true.

Explanation:

In order for cells, muscular and neuronal, to perform their activities, they need to generate action potentials, that will permit these activities. In order for an action potential to happen, a cell´s membrance must be charged, or rather, its polarity must be changed, so that the cell can be charged and then fire. Usually, cells remain in a resting membrane state, in which, the extracellular matrix remains positive, while the intracellular space remains positive, due to ion, and anion presence in either. In order for the action potential to happen, these polarities are reversed through a series of steps in which ions, particularly potassium and sodium, sometimes calcium, will enter and exit the cell´s membrane to change this polarity. But in order for this process to take place, first a current, or stimulation, must motivate the cell to start the process. The capacitance is the capability of a cell to be ready to be activated or de-activated when stimulated, meaning, to be charged and discharged, when necessary. In order for this capacitance to permit the process of action potential formation, it needs to be discharged first, and this is done through the stimulus, which orders the cell´s membrane to initiate depolarization by opening up the ion channels. This is why the answer is true.

Which 2 interventions should the nurse be prepared to perform for a patient who is receiving an epinephrine infusion?

podryga [215]

The nurse should be prepared to monitor pulse and ventilation immediately for a patient receiving epinephrine infusion.

Epinephrine, often called adrenaline, is a very potent drug that may produce adverse side effects if taken in inappropriate amounts. It is used to treat cardiac arrest, hypotension, or severe allergies, known as anaphylaxis, caused by some insect's bite.

Some of its side effects include respiratory problems, dizziness, headache, weakness, nausea, pale skin, sweating, feeling nervous, anxious, or fearful.

Thus the nursing interventions should be performed as:

● Assess the patient's respiratory count, pulse, blood pressure, and urine output continuously

● Administer the dose carefully in appropriate amounts- usually, the dose does not exceed 1mg

● Report it to the doctors if any of the side effects do not vanish in 20 minutes after the infusion.
