A. Atropine

8. Select all the signs and symptoms below that can present in myasthenia gravis: A. Respiratory failure B. Increased salivation C. Diplopia D. Ptosis E. Slurred speech F. Restlessness G. Mask-like appearance of looking sleepy H. Difficulty swallowing

A. Respiratory failure C. Diplopia D. Ptosis E. Slurred speech F. Restlessness G. Mask-like appearance of looking sleepy H. Difficulty swallowing

9. You're providing teaching to a group of patients with myasthenia gravis. Which of the following is not a treatment option for this condition? A. Plasmapheresis B. Cholinesterase medications C. Thymectomy D. Corticosteroids

B. Cholinesterase medications These medications are not used to treat MG, but ANTIcholinesterase medications (like Pyridostigmine) are used to treat this condition.

10. You're a home health nurse providing care to a patient with myasthenia gravis. Today you plan on helping the patient with bathing and exercising. When would be the best time to visit the patient to help these tasks? A. Mid-afternoon B. Morning C. Evening D. Before bedtime

B. Morning Patients with MG tend to have the best muscle strength in the morning after sleeping or resting rather than at the end of the day....the muscles are tired from being used and the muscle become weaker as the day progresses etc. Therefore any rigorous activities are best performed in the morning or after the patient has rested.

1. Myasthenia gravis occurs when antibodies attack the __________ receptors at the neuromuscular junction leading to ____________. A. metabotropic; muscle weakness B. nicotinic acetylcholine; muscle weakness C. dopaminergic adrenergic; muscle contraction D. nicotinic adrenergic; muscle contraction

B. nicotinic acetylcholine; muscle weakness

3. A patient with myasthenia gravis will be eating lunch at 1200. It is now 1000 and the patient is scheduled to take Pyridostigmine. At what time should you administer this medication so the patient will have the maximum benefit of this medication? A. As soon as possible B. 1 hour after the patient has eaten (at 1300) C. 1 hour before the patient eats (at 1100) D. at 1200 right before the patient eats

Which findings after the administration of Edrophonium would represent the patient has myasthenia gravis? A. The patient experiences worsening of the muscle weakness. B. The patient experiences wheezing along with facial flushing. C. The patient reports a tingling sensation in the eyelids and sudden ringing in the ears. D.
