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 B

Explanation

Choice A Reason: Swollen, painful joints are not a sign of Lyme disease in the early stage, but they may occur in the late stage, which can take months or years to develop.

Choice B Reason: An expanding circular rash, also known as erythema migrans, is a sign of Lyme disease in the early stage, which usually appears within 3 to 30 days after the tick bite. The rash may have a bull's-eye appearance and can spread up to 12 inches in diameter.

Choice C Reason: Decreased level of consciousness is not a sign of Lyme disease, but it may indicate other serious conditions such as meningitis, encephalitis, or stroke.

Choice D Reason: Necrosis at the site of the bite is not a sign of Lyme disease, but it may indicate a brown recluse spider bite, which can cause tissue damage and ulceration.

A. Side lying on the affected eye. B. Supine C. Prone D. Semi Fowler's

Correct Answer is D

Explanation

Choice A Reason: Side lying on the affected eye is not the correct position for the client after cataract surgery, as it may increase intraocular pressure and cause bleeding or damage to the surgical site.

Choice B Reason: Supine is not the correct position for the client after cataract surgery, as it may cause fluid accumulation and swelling in the eye.

Choice C Reason: Prone is not the correct position for the client after cataract surgery, as it may cause pressure and friction on the eye.

Choice D Reason: Semi Fowler's is the correct position for the client after cataract surgery, as it helps to reduce intraocular pressure and promote drainage and healing of the eye.
