Answer:

The correct answer is Zones of tolerance

Explanation:

All living organisms such as fish,plants and animals  need water to survive and also the require certain pH level of water in order to be healthy.Its a acid and base balance reaction.Strong acids dissolve into water and its changes water's pH.if water's pH level drops it becomes acidic suppose a fish waste ammonia releases and dissolves in water to form harmless ammonia ions,carbon dioxide ions and hydrogen ions even some limestone also rises pH level and water becomes more basic.To make the tank water alkaline, add some corals and aerate the tank water by fixing an air pump so that excess of carbon dioxide eliminate out and water pH level comes to neutral this is the reason water becomes slightly alkaline and the fishes are able to reproduce.

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.
