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.

Explanation
Choice A Reason: Following a high-fiber diet to establish bowel regularity is an appropriate instruction for a client who has hemorrhoids, as it helps to soften stools and reduce straining and pressure on hemorrhoids.
Choice B Reason: Using a stimulant laxative to prevent constipation is not an appropriate instruction for a client who has hemorrhoids, as it may cause diarrhea, dehydration, or electrolyte imbalance.
Choice C Reason: Cleaning the anal area after bowel movements with alcohol-based wipes is not an appropriate instruction for a client who has hemorrhoids, as it may irritate, dry, or damage hemorrhoidal tissue.
Choice D Reason: Limiting the intake of fruit to prevent loose stools is not an appropriate instruction for a client who has hemorrhoids, as fruit is a good source of fiber and fluid that can help prevent constipation and hemorrhoids.
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.
