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 C
Explanation
Choice A Reason: Placing an ice pack on the lips if they swell is not an appropriate instruction for a client who is taking allopurinol, as it may indicate an allergic reaction or angioedema, which requires immediate medical attention.
Choice B Reason: Using an OTC antihistamine lotion if a rash develops is not an appropriate instruction for a client who is taking allopurinol, as it may indicate a serious skin reaction such as Stevens-Johnson syndrome or toxic epidermal necrolysis, which requires immediate medical attention.
Choice C Reason: Drinking at least 8 glasses of fluid every day is an appropriate instruction for a client who is taking allopurinol, as it helps to prevent kidney stones and flush out uric acid from the body.
Choice D Reason: Taking the medication on an empty stomach 2 hours before meals is not an appropriate instruction for a client who is taking allopurinol, as it may cause stomach upset or nausea. The medication should be taken after meals with plenty of water.
Correct Answer is C
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.
