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."

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:

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.
