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 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.
Correct Answer is D
Explanation
A) Check the client's perianal skin integrity:
Assessing perianal skin integrity is important in the care of a client with ulcerative colitis, particularly due to the potential for diarrhea and irritation. However, this is not the first priority upon admission for an acute exacerbation.
B) Educate the patient on which foods the patient should eat:
Nutritional education is crucial in managing ulcerative colitis, but it is not the priority during the initial assessment and admission for an acute exacerbation. Stabilizing the client's condition and addressing immediate needs take precedence.
C) Investigate the client's emotional concerns:
While emotional support is important, particularly in chronic conditions like ulcerative colitis, assessing emotional concerns is not the first action required upon admission for an acute exacerbation. Physical stabilization and assessment of the client's condition are the initial priorities.
D) Review the client's electrolyte values:
This is the correct answer. During an acute exacerbation of ulcerative colitis, there is a risk of electrolyte imbalance due to diarrhea and fluid loss. Reviewing the client's electrolyte values is crucial to assess the severity of dehydration and electrolyte imbalances, which can have immediate implications for the client's treatment plan and stabilization.
