b. False

Answer 1
Answer:

Answer:

The answer to the question: The membrane potential seeks the equilibrium potential of the ion whose permeability is dominant, would be, True.

Explanation:

When a cell needs to prepare to activate itself, or start what is known as an action potential, there needs to be a change in the polarity that is constant over the cell membrance. Usually, this polarity tends to be primarily negative on the inside thanks to the anions, and positive on the extracellular side, thanks to the concentration, particularly of sodium ions. In general, and without stimulus, this resting membrane will not activate or generate anything. However, when the cell activates, several channels, both leakage and gated, will activate to allow the two most important ions, sodium and potassium, to leak in and out of the cell to generate an electrical gradient. In order to restore this, and return to resting, the cell´s membrane must restore its potential, and thus, it will activate the channels of the dominant ion, to restore the balance. In fact, normally, there are leakage potassium channels in the cell membrane that allow potassium to leak out of the cell, helping to maintain the negativity of the cytoplasm, and the stability.

18) If heart rate is decreasing, what portions of the nervous system are being activated? Highlight allthat apply.
Afferent division
Somatic nervous system
Sympathetic nervous system
Efferent division
Autonomic nervous system
Parasympathetic nervous system

Answers

Answer:

Autonomic nervous system

parasympatheic nervous system

Final answer:

When the heart rate decreases, the parasympathetic and autonomic nervous systems are activated.

Explanation:

When the heart rate decreases, the portions of the nervous system that are activated include the parasympathetic nervous system and the autonomic nervous system. The parasympathetic nervous system is responsible for rest and digest activities, and it slows down the heart rate. The autonomic nervous system controls involuntary body functions, including heart rate, and it consists of both the sympathetic and parasympathetic divisions.

Who has the authority to decide if a postmortem will be conducted if a client dies 2 hours after being admitted to the hospital

Answers

Answer:

medical examiner

Final answer:

The authority to decide if a postmortem will be conducted can belong to the attending doctor, hospital authority, coroners, or medical examiners. Factors influencing this decision include the suddenness, unexpectedness, or suspicion surrounding the death, and the decision can be influenced by laws that vary by jurisdiction.

Explanation:

Typically, the authority to decide if a postmortem will be conducted rests within several hands. An attending doctor or the hospital authority generally makes this decision, often based on certain conditions or suspicion of medical malpractice. However, in cases of sudden, unexpected, or suspicious deaths, coroners or medical examiners may also have the authority to order an autopsy. Laws regulating postmortem examinations vary by jurisdiction, so it could also depend on the rules and guidelines in the specific location of the hospital. For deaths in the hospital shortly after admission, it is critical to determine the cause to prevent similar incidents in the future, which is why a postmortem might be conducted.

A blind man gets marooned in a desert. He has 2 red pills and 2 blue pills with him. The pills are identical in size and shape. To stay alive, he must take 1 red pill and 1 blue pill. Any other combination of pills would bring him certain death. How can the blind man ensure that he takes exactly 1 red pill and 1 blue pill?

Answers

Answer:

well, put all 4 of them in your mouth, next, take the drenched pills out of your mouth and examine 2 of them, put the rest in your pocket. blue dries faster, now we know how to differentiate them. To conclude it up, take the pills that are dry and wet. if both pills dry at a near time ratio, eat one from your hand, and another from your pocket.

Explanation:

A beer koozie is designed to keep a beer cold. The koozie is effective at blocking heat transfer from your warm hand into the cold beer and it also prevents condensation from forming on the side of the beer. Why does preventing condensation on a beer bottle keep the beer cool on a hot humid day?

Answers

Answer:

Water-vapour molecules give of their heat to convert into liquid water which is absorbed by the surface on which they condense.

Explanation:

  • Preventing condensation on the surface of a cold beer container will prevent the heat gain by the beer by absorbing the energy from the surrounding molecules of the water vapour present in the air in the form of humidity.
  • When water vapour of the atmosphere which is present in the form of humidity condenses on the cold surface it releases the latent heat of vapourization to the cold surface of the container which is directly in contact with the beer which further absorbs the heat form the container.
  • We know that the latent heat of vapourization of water is 2260\ kJ.kg^(-1) . This amount of heat is very high and can lead to gain of temperature considerably.

Answer:

Water-vapour molecules give of their heat to convert into liquid water which is absorbed by the surface on which they condense.

A registered nurse (RN) is supervising the work of a licensed practical nurse (LPN) who is caring for a client diagnosed with a terminal illness. Which statement by the LPN would be corrected by the RN?

Answers

Answer: B. The law says you must write a new living will each time you re admitted to the hospital.

Explanation:

The law does not require that you make a new will whenever you are admitted to the hospital. Any existing will that has fulfilled the provisions of the law are biding unless the person decides to change the will of their own volition.

There is therefore no need to make a new will every time if there is already one in existence and the person is satisfied with it. The Registered Nurse should therefore correct this statement by the Licensed Practical Nurse.
