A nurse is caring for a client with myasthenia gravis who is exhibiting signs of cholinergic crisis. Which medication does the nurse ensure is available to treat this crisis?
Atropine sulfate
Pyridostigmine bromide (Mestinon)
Protamine sulfate
Acetylcysteine (Mucomyst)
The Correct Answer is A
Choice A Reason: Atropine sulfate is the medication that the nurse should ensure is available to treat cholinergic crisis, as it blocks the effects of acetylcholine and reverses the symptoms of excessive parasympathetic stimulation.
Choice B Reason: Pyridostigmine bromide (Mestinon) is not the medication that the nurse should ensure is available to treat cholinergic crisis, but it is used to treat myasthenia gravis by increasing acetylcholine levels and improving muscle strength.
Choice C Reason: Protamine sulfate is not the medication that the nurse should ensure is available to treat cholinergic crisis, but it is used to reverse the effects of heparin and prevent bleeding.
Choice D Reason: Acetylcysteine (Mucomyst) is not the medication that the nurse should ensure is available to treat cholinergic crisis, but it is used to treat acetaminophen overdose and prevent liver damage.

Correct Answer is D
Explanation
Choice A Reason: Parkinson's disease does not result from too low acetylcholine as a result of an autoimmune reaction, but this may be a description of myasthenia gravis, which affects the neuromuscular junction.
Choice B Reason: Parkinson's disease is not caused by the deterioration of the myelin sheath of the basal ganglia, but this may be a description of multiple sclerosis, which affects the central nervous system.
Choice C Reason: Excess dopamine and deficient acetylcholine are not the two major causes of Parkinson's disease, but they are reversed. Parkinson's disease is caused by low dopamine and high acetylcholine levels in the brain.
Choice D Reason: Parkinson's is caused by depletion of dopamine and excess of acetylcholine, as this affects the balance between these two neurotransmitters that control movement and coordination.
Correct Answer is D
Explanation
Choice A Reason: Compressing the nares is not the first action that the nurse should take, as it may increase intracranial pressure and worsen the head injury.
Choice B Reason: Administering decongestant for postnasal drip is not the first action that the nurse should take, as it may mask the signs of cerebrospinal fluid (CSF) leakage and delay diagnosis and treatment.
Choice C Reason: Tilting the head back is not the first action that the nurse should take, as it may cause aspiration of CSF or blood and increase the risk of infection.
Choice D Reason: Collecting the drainage is the first action that the nurse should take, as it helps to identify if the drainage is CSF or nasal secretions, and to monitor the amount and characteristics of the drainage.
