Answer:

The answer is: <em><u> It means it is a membrane that will allow certain molecules or ions to pass through it by means of active or passive transport. </u></em>

Explanation:

All cells are enclosed with a cell membrane. The term, <u>selectively permeable</u>, refers to :

the membrane allows some substances or molecules to enter the cells, and others to be prevented from entering. It also allows substances to leave the cell.

This process can be done by :

Active transport -requires the cell to expend energy to move the materials.

Passive transport- it can be done without using cellular energy.

Question 2 the nurse is caring for a patient who is receiving diphenhydramine. the nurse notes that the patient has not voided f
Delvig [45]
Diphenhydramine (Benadryl) is an H1-antagonist, with unfortunate anti-cholinergic side effects: dry mouth (xerostomia), dry eyes (xerophthalmia), and also including urinary hesitancy and inability to void.
I would presume to think that the next best action would be to evaluate the bladder for bladder distension.
If overly distended, then a urinary (foley) catheterization may be warranted to void the patient. However, ordering a Foley first may be an unnecessary, uncomfortable, and likely painful procedure.
After examining the bladder externally (suprapubically), then fluids may be warranted.
