"Facilitative transporter of glucose" is not a role of the cystic fibrosis transmembrane conductance regulator (CFTR).

<u>Option:</u> B

<u>Explanation:</u>

A protein and chloride pathway of membrane, in vertebrates encoded with the CFTR gene is understood as "Cystic fibrosis transmembrane conductance regulator (CFTR)". The CFTR gene codes for an ABC-class transporter ion channel protein that conducts chloride ions through epithelial membranes of cells.

The protein helps to keep the salt and water equilibrium on many surfaces in the body, including the lung surface. When the protein doesn't work properly, chloride — a salt part — gets trapped in cells.

The registered nurse is evaluating the statements of the student nurse after teaching about delegation. Which statement made by
Oxana [17]

Answer:

The options

"The delegatee should report the findings back to the delegator."

"The delegatee should understand the assigned task completely."

"The delegator should trust the delegatee to accomplish the task."

"The delegator should recheck and redo the work of the delegatee."

The CORRECT ANSWER IS

"The delegator should recheck and redo the work of the delegatee.

Explanation:

An effective leader must learn to effectively delegate tasks by appropriating the tasks based on skill and talent of his/her members in order to increase productivity and accuracy.

"The delegator should recheck and redo the work of the delegatee."✔

Time management is a necessary factor in delegation processes. If the delegator needs to rechecks and redoes the task assigned to the delegatee, it consumes time needed for other tasks and slows the process of achieving the task and results due to inappropriate delegation.

"The delegatee should report the findings back to the delegator."❌

Reporting the results after it's being carried out to the delegator would give the delegator a clear view on how the process of the task is going.

"The delegatee should understand the assigned task completely."❌

The delegatee needs to comprehend the task completely to perform to details as instructed by the delegator.

"The delegator should trust the delegatee to accomplish the task."❌

Trusting the delegatee decrease the time to get it done and promote a healthy working atmosphere.
