A nurse is reinforcing teaching with a client who has a new diagnosis of myasthenia gravis (MG) and a prescription for neostigmine. Which of the following information should the nurse include about the action of the medication?
Improves muscle strength.
Destroys the antibodies that cause MG
Enhances immune system function
Prevents excessive coughing
The Correct Answer is A
a. Improves muscle strength.
Explanation:
Neostigmine is a medication used in the treatment of myasthenia gravis (MG). It belongs to a class of drugs called cholinesterase inhibitors. Neostigmine works by inhibiting the breakdown of acetylcholine, a neurotransmiter involved in muscle contraction. In MG, there is a decrease in the amount of acetylcholine available at the neuromuscular junction, leading to muscle weakness and fatigue.
By inhibiting the breakdown of acetylcholine, neostigmine helps to increase the concentration of acetylcholine at the neuromuscular junction. This, in turn, improves muscle strength and can alleviate the symptoms of weakness and fatigue associated with MG.
Option b, destroying the antibodies that cause MG, is not accurate. Myasthenia gravis is an autoimmune disorder characterized by the presence of antibodies that interfere with neuromuscular transmission.
Neostigmine does not directly target or eliminate these antibodies.
Option c, enhancing immune system function, is not accurate either. Neostigmine primarily acts on the neuromuscular junction to improve muscle strength and does not have a direct effect on immune system function.
Option d, preventing excessive coughing, is not the primary action of neostigmine. While increased muscle strength may indirectly improve respiratory function and reduce coughing in individuals with myasthenia gravis, it is not the primary indication or action of neostigmine.
Therefore, the most accurate information to include in teaching about neostigmine for a client with myasthenia gravis is that it improves muscle strength.

Correct Answer is A
Explanation
- A. This choice is correct because a child who has autism spectrum disorder often exhibits strict adherence to routines and rituals, and may become distressed or agitated when there are changes or disruptions to their usual patterns.
- B. This choice is incorrect because difficulty paying attention to tasks is not a specific manifestation of autism spectrum disorder, but rather a common symptom of attentiondeficit/hyperactivity disorder (ADHD). A child who has autism spectrum disorder may have difficulty focusing on tasks that are not of interest to them, but may also show intense concentration on tasks that are of interest to them.
- C. This choice is incorrect because disobedience to authority figures is not a specific manifestation of autism spectrum disorder, but rather a common behavior problem in children and adolescents. A child who has autism spectrum disorder may have difficulty understanding social cues and expectations, but may also show compliance and cooperation when given clear instructions and positive reinforcement.
- D. This choice is incorrect because excessive anxiety when separated from parents is not a specific manifestation of autism spectrum disorder, but rather a common symptom of separation anxiety disorder. A child who has autism spectrum disorder may have difficulty forming attachments and expressing emotions, but may also show affection and attachment to familiar people.
Correct Answer is B
Explanation
- A. Incorrect. The nurse should check the functioning of oxygen equipment daily, not weekly, to ensure safety and proper delivery of oxygen.
- B. Correct. The nurse should instruct the client to wear clothing made with cotton fabrics while oxygen is in use, as synthetic fabrics can generate static electricity and cause sparks that could ignite the oxygen.
- C. Incorrect. The nurse should instruct the client to avoid petroleum-based lubricants, such as Vaseline, as they are flammable and could cause burns if exposed to oxygen. The nurse should recommend water-soluble lubricants, such as K-Y jelly, instead.
- D. Incorrect. The nurse should instruct the client to store full oxygen tanks upright, not on their side, to prevent them from rolling and damaging the valve or regulator.
