A nurse is explaining myasthenia gravis to a family. Which of the following points would be included in the explanation? (Select All that Apply.)
Is it caused by demyelination of the nerve fibers.
Is it thought to be an autoimmune disease.
It is associated with destruction of acetylcholine receptor sites.
Once symptoms present, it has a 5-year survival rate.
It is a chronic and progressive muscular disease.
Is it best treated with antibiotics.
Correct Answer : B,C,E
A) Is it caused by demyelination of the nerve fibers:
Myasthenia gravis is not primarily caused by demyelination of nerve fibers. It is characterized by dysfunction at the neuromuscular junction, specifically involving the acetylcholine receptors.
B) Is it thought to be an autoimmune disease:
This is correct. Myasthenia gravis is considered an autoimmune disorder in which the body's immune system mistakenly targets and attacks its own tissues, particularly the acetylcholine receptors at the neuromuscular junction.
C) It is associated with destruction of acetylcholine receptor sites:
This is correct. In myasthenia gravis, there is a reduction in the number of functional acetylcholine receptors due to autoimmune-mediated destruction or blocking of these receptors.
D) Once symptoms present, it has a 5-year survival rate:
This statement is inaccurate. Myasthenia gravis is a chronic condition, but survival rates are not determined by the onset of symptoms. With appropriate treatment, many individuals with myasthenia gravis can manage their symptoms effectively and have a normal life expectancy.
E) It is a chronic and progressive muscular disease:
This is correct. Myasthenia gravis is a chronic neuromuscular disorder characterized by fluctuating muscle weakness and fatigue. While it is chronic, it is not necessarily progressive in all cases, as symptoms may stabilize or improve with treatment.
F) Is it best treated with antibiotics:
Antibiotics are not the primary treatment for myasthenia gravis. Treatment typically involves medications that enhance neuromuscular transmission, such as acetylcholinesterase inhibitors or immunosuppressive drugs, along with other supportive measures.

Correct Answer is A
Explanation
A) "I will weigh myself daily and report significant changes in weight":
This statement demonstrates an understanding of the nurse's teaching about diuretics. Diuretics are medications that promote diuresis, leading to increased urine output and fluid loss. Monitoring weight daily can help the client identify fluid retention or volume overload, which are common concerns in individuals taking diuretics. Significant changes in weight, such as sudden increases, may indicate fluid retention or worsening heart failure and should be reported to the healthcare provider promptly for further evaluation.
B) "If my leg gets swollen again, I'll be sure to take an additional pill":
This statement indicates a misunderstanding of the nurse's teaching. Taking an additional pill without healthcare provider guidance can lead to medication overdose and potential adverse effects. It's important for clients to follow the prescribed dosage regimen and consult their healthcare provider before making any changes to their medication regimen.
C) "I will take my medication before bedtime":
While taking diuretics before bedtime may be appropriate for some individuals, it is not a universal recommendation. The timing of diuretic administration can vary depending on the specific type of diuretic prescribed, the client's individual needs, and the presence of any coexisting conditions. Therefore, this statement does not necessarily indicate an understanding of the nurse's teaching about diuretics.
D) "I will have to limit my high sugar foods":
This statement does not directly relate to the nurse's teaching about diuretics. While dietary modifications may be necessary for certain health conditions, such as diabetes, they are not specifically related to the mechanism of action or management of diuretic therapy. Therefore, this statement does not demonstrate an understanding of the nurse's teaching about diuretics.
Correct Answer is C
Explanation
A) "I should limit my fluid intake while taking this medication":
This statement is incorrect. Furosemide is a loop diuretic that increases urine production to reduce fluid overload in conditions like heart failure or edema. It is essential for clients taking furosemide to maintain adequate hydration to prevent dehydration. Therefore, the client should not limit their fluid intake while taking this medication.
B) "My blood pressure will increase while I am taking this medication":
This statement is incorrect. Furosemide is primarily used to reduce blood pressure by promoting diuresis and reducing fluid volume. Therefore, it is unlikely that blood pressure would increase while taking this medication.
C) "I should take this medication in the morning rather than at night":
This is the correct answer. Furosemide is usually taken in the morning to prevent nocturia (excessive urination at night), as it can increase urinary frequency. Taking it earlier in the day allows for better fluid balance during waking hours and reduces the need to wake up frequently during the night to urinate.
D) "I should eat a diet low in potassium while taking this medication":
This statement is incorrect. Furosemide can cause potassium depletion as a side effect, so clients may be advised to consume potassium-rich foods or supplements unless contraindicated due to other medical conditions. However, it is not necessary to eat a diet low in potassium while taking furosemide unless specifically instructed by a healthcare provider.
