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
Choice A rationale:
The nurse should include the statement, "Use a product with DEET on your skin and clothes when you are walking in a wooded area," in the educational program on Lyme disease. DEET is a widely used insect repellent effective against ticks. It is recommended to prevent tick bites in wooded and grassy areas. The rationale behind this choice is to educate the public about practical measures to reduce the risk of Lyme disease. DEET repels ticks, reducing the chances of tick attachment and, consequently, the transmission of Lyme disease.
Choice B rationale:
The statement, "Symptoms of Lyme disease appear 2 days after being bitten by an infected tick," is incorrect. The incubation period for Lyme disease can vary from 3 to 30 days after the tick bite. Symptoms usually appear within 3 to 14 days but can take longer to manifest. Providing inaccurate information can lead to misunderstanding and inadequate preventive measures.
Choice C rationale:
The statement, "Remove embedded ticks by squeezing the body with tweezers," is incorrect. Improper removal of ticks, such as squeezing the body, can lead to the injection of tick fluids into the host, increasing the risk of disease transmission. The correct method for tick removal is to use fine-tipped tweezers to grasp the tick as close to the skin's surface as possible and pull upward with steady, even pressure. This helps ensure the tick is removed entirely and reduces the risk of infection.
Choice D rationale:
The statement, "If bitten by a tick, testing for Lyme disease should occur within 2 weeks," is incorrect. Testing for Lyme disease immediately after a tick bite is not recommended because it takes time for the body to produce antibodies detectable by the tests. Testing too early can yield false-negative results. Healthcare providers may recommend testing if symptoms develop, but waiting for a few weeks after the bite increases the accuracy of the test results.
Correct Answer is B
Explanation
- A. Chest x-ray is not correct because it is not related to valproic acid therapy or its adverse effects.
- B. Serum liver enzyme levels is correct because valproic acid can cause hepatotoxicity and liver function tests should be monitored regularly.
- C. ABGS is not correct because it is not indicated for valproic acid therapy or its adverse effects.
- D. Urine culture and sensitivity is not correct because it is not related to valproic acid therapy or its adverse effects.
