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 C
Explanation
- A is incorrect because it is an example of self-disclosure, not altruism. Self-disclosure is sharing personal information or feelings with others.
- B is incorrect because it is an example of jealousy, not altruism. Jealousy is feeling threatened or resentful by someone else's success or happiness.
- C is correct because it is an example of altruism, which is helping others without expecting anything in return. Altruism can enhance self-esteem and coping skills for clients who have breast cancer.
- D is incorrect because it is an example of trust, not altruism. Trust is believing that someone is reliable and honest.
Correct Answer is B
Explanation
"Have you had any stomach pain or bloody stools?"
Rationale:
- A. Muscle stiffness is not a common or serious adverse effect of ibuprofen. Ibuprofen is an antiinflammatory drug that can reduce pain and stiffness caused by arthritis.
- B. Stomach pain or bloody stools are signs of gastrointestinal bleeding, which is a serious and potentially fatal adverse effect of ibuprofen. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can cause ulceration, perforation, and hemorrhage of the stomach or intestines . The nurse should ask the client about any gastrointestinal symptoms and advise them to avoid alcohol, smoking, and other NSAIDs while taking ibuprofen.
- C. Dry cough is not a common or serious adverse effect of ibuprofen. Dry cough is more likely to be caused by angiotensin-converting enzyme (ACE) inhibitors, which are used to treat hypertension and heart failure.
- D. Increase in urine output is not a common or serious adverse effect of ibuprofen. Ibuprofen can cause renal impairment, which can lead to decreased urine output, not increased urine output. The nurse should monitor the client's renal function tests and fluid balance while taking ibuprofen.
