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
Choice A rationale:
Limiting fluid intake to 1 liter per day can lead to dehydration and other health complications. It is important for the client to maintain adequate hydration, especially postpartum. This option is incorrect and potentially harmful.
Choice B rationale:
Manual expression of milk can help relieve engorgement without stimulating further milk production. This method allows the client to express milk as needed. However, it can be done even before engorgment occurs
Choice C rationale:
Wearing a snug-fitting bra can provide support and comfort.
Choice D rationale:
Applying moist heat to the breasts can stimulate milk production and relieve engorgement. However, in this case, the client wants to suppress lactation. Therefore, this option is not appropriate and may have the opposite effect of increasing milk production.
Correct Answer is A
Explanation
Choice A rationale:
The nurse should ensure that the side rails are up on the client's bed. This action is essential for the safety of the client with severe preeclampsia, as it prevents accidental falls or injuries. Preeclampsia is a hypertensive disorder of pregnancy characterized by high blood pressure and signs of organ damage, and it poses significant risks to both the mother and the fetus. By keeping the side rails up, the nurse can minimize the risk of falls and ensure the client's safety while in bed.
Choice B rationale:
Ambulating the client every 4 hours is not appropriate for a pregnant woman with severe preeclampsia. Preeclampsia can cause high blood pressure, swelling, and proteinuria. It is a serious condition that requires close monitoring and strict bed rest to prevent complications such as seizures or eclampsia. Ambulation may increase the risk of falls and is contraindicated in this situation.
Choice C rationale:
Checking the fetal heart rate twice daily is important in the care of a pregnant client with severe preeclampsia. However, ensuring the client's safety by keeping the side rails up on the bed takes priority. While monitoring the fetal heart rate is crucial for assessing the baby's well-being, it does not address the immediate safety concerns of the client, which can be addressed by maintaining the side rails up.
Choice D rationale:
Providing the client with a low-protein diet is not the correct action for a pregnant woman with severe preeclampsia. In fact, pregnant women with preeclampsia are often advised to increase their protein intake to help manage their condition. A low-protein diet can lead to malnutrition and may not provide the necessary nutrients for both the mother and the developing fetus. The primary focus should be on bed rest, monitoring vital signs, and managing symptoms to prevent complications.
