how is that ion channels that let in positive charge could hyperpolarized a hair cell?

A. they feature unique residues that allow positive charge to go both directions
B. their ligands let out potassium ions, creating a negative electrochemical gradient
C. their ion channels are partially open at a resting state, and so closing them reduces the positive charge going into the cell
D. Ion channels that bind inverse agonist will reverse active ion transport, but only in the axon Hillock, leading to hyperpolarization down the axon

Answer:

B. their ligands let out potassium ions, creating a negative electrochemical gradient

Explanation:

A ciliated cell would be hyperpolarized by the action of positive ion kennels, when that cell received an inhibitory stimulus and the action of these channels allowed its ligands to release potassium ions (K +) and allow the entry of chlorine ions (Cl-), creating a negative electrochemical gradient, since the interior of the cell will have a negative potential greater than the external environment, which will be more positive. The result of this is to inhibit the spread of an action potential in the cellular environment.

A hospital client's health status has declined sharply, and a referral to palliative care has been made. A nurse has suggested a referral to spiritual care, but a colleague states, "That is not likely necessary because the client's health record states 'no religion.'" How should the nurse best respond to the colleague's statement

According to current dietary recommendations, trans fat intake should be limited. How is this best accomplished? a. Select foods containing manufactured rather than naturally occurring trans fats. b. Read labels to select foods that say "polyunsaturated fatty acid free." c. Avoid all processed foods such as bakery items, packaged cookies, and store-bought bread. d. Use fat replacers, such as olestra, which provide the same nutrient content as regular fats without being saturated. e. Choose foods with <10% of calories from saturated fat per serving and no hydrogenated oils in the ingredients list.

Doctors and nutritionists use BLANK as a screening tool to assess weight in adults. They generally make further assessments to determine the amount of body fat that the person actually has.
