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: Lantus is not a type of insulin that can treat this client, as it is a long-acting insulin that has no peak effect and lasts for 24 hours.
Choice B Reason: NPH is not a type of insulin that can treat this client, as it is an intermediate-acting insulin that peaks in 6 to 8 hours and lasts for 12 to 18 hours.
Choice C Reason: Regular is a type of insulin that can treat this client, as it is a short-acting insulin that peaks in 2 to 4 hours and lasts for 6 to 8 hours. It can be used to correct high blood glucose levels and treat diabetic ketoacidosis (DKA), which is indicated by confusion, flushing, and acetone breath.
Choice D Reason: Lispro is not a type of insulin that can treat this client, as it is a rapid-acting insulin that peaks in 30 minutes and lasts for 3 to 5 hours. It can be used to cover meals or snacks but not to treat DKA.

Choice B Reason: Dry, scaly skin and cold intolerance are not physical assessment findings that the nurse would expect to observe in a client with Cushing's syndrome, but they may indicate hypothyroidism, which affects the metabolism and skin condition.
Choice C Reason: Dry, sticky mucous membranes and hypovolemia are not physical assessment findings that the nurse would expect to observe in a client with Cushing's syndrome, but they may indicate dehydration or diabetes insipidus, which affect the fluid balance and urine output.
