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.

Answer:
D
Explanation:
Vegetation on soil protects the soil from erosion because its roots and root hairs help bind the soil particles together. This occurs mechanically by binding soil into crumbs and also chemically by providing organic matter that binds the soil particle into humus that holds moisture. The soil becomes heavy to be carried off by wind erosion. Trees also break the down flow of water hence reducing the capacity of runoff to carry soil sediments.
