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)

Answer and Explanation

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: Irrigating the fistula with 3 mL of normal saline solution is not a correct way to assess the patency of the fistula, as it may cause bleeding, infection, or dislodgement of the fistula.

Choice B Reason: Flushing the fistula with 1 mL of heparin solution once per shift is not a correct way to assess the patency of the fistula, as it may cause clotting, infection, or allergic reaction.

Choice C Reason: Infusing 50 mL of normal saline once per 24 hours is not a correct way to assess the patency of the fistula, as it may cause fluid overload, hypertension, or edema.

Choice D Reason: Palpating for a vibrating sensation at the fistula site is a correct way to assess the patency of the fistula, as it indicates that there is adequate blood flow through the fistula. This sensation is also known as a thrill.

A. Lantus B. NPH C. Regular D. Lispro

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.
