If the concentration of salt in the fluid surrounding cells decreases and the concentration of other solutes remains constant?
svetoff [14.1K]

Answer:

The cell will swell.

Explanation:

The cells react distinctly when placed in different solutions like hypertonic, isotonic and hypotonic solutions. In the mentioned question, that is, in the fluid surrounding the cells, the concentration of salt reduces, which makes the solution hypotonic. Hypotonic solution exhibit high water potential and low solute concentration.  

This makes the water move from the hypotonic solution to the inside of the cell as the osmotic movement occurs from high solvent concentration to low solvent concentration, thus, swelling of the cell takes place.

Natali5045456 [20]

The question is incomplete, the complete question is:

A client with myasthenia gravis improves and is discharged from the hospital. The discharge medications include pyridostigmine bromide (Mestinon) 10 mg every six hours. The nurse evaluates that the drug regimen is understood when the client says, "I should:

1

Take the medication on an empty stomach."

2

Set an alarm so I take the medication on time."

3

Take my pulse rate before taking the medication."

4

Monitor for an increase in blood pressure after taking the medication."

Answer:

The correct answer is statement 2.

Explanation:

Pyridostigmine refers to an essential drug, which must be consumed on time, as a late or missed dose can lead to extreme neuromuscular and respiratory consequences or even death. Pyridostigmine should be consumed with a small concentration of food in order to inhibit gastric irritation.  

It is not essential to take the pulse rate prior to taking the medication. Pyridostigmine may result in hypotension, however, not hypertension, which is not an indication of cholinergic crisis.
