removes the client's blood and returns high dose corticosteroids to the patient.

removes the autoantibodies responsible for Myasthenia Gravis."

treats the thymus gland dysfunction responsible for Myasthenia Gravis.

assists in the immune suppression along with corticosteroids.

Answer and Explanation

The Correct Answer is B

A. removes the client's blood and returns high-dose corticosteroids to the patient: Plasmapheresis involves the removal of plasma from the blood, but it does not involve returning high-dose corticosteroids. It removes harmful substances (such as autoantibodies) from the plasma that contribute to disease symptoms, but it does not involve corticosteroid therapy directly.

B. removes the autoantibodies responsible for Myasthenia Gravis: In Myasthenia Gravis (MG), autoantibodies attack the acetylcholine receptors at the neuromuscular junction, leading to muscle weakness. Plasmapheresis is used to remove these autoantibodies from the bloodstream, helping to temporarily improve symptoms by reducing the immune system’s attack on the body’s own tissues.

C. treats the thymus gland dysfunction responsible for Myasthenia Gravis: Plasmapheresis does not directly treat the thymus gland. In some cases, thymectomy (removal of the thymus gland) may be indicated for MG, but plasmapheresis specifically addresses the immune response, not the thymus.

D. assists in the immune suppression along with corticosteroids: While plasmapheresis can temporarily reduce the autoimmune response, it does not function as a form of immune suppression like corticosteroids. Corticosteroids are immunosuppressive medications, but plasmapheresis itself is a physical process that removes harmful autoantibodies from the blood

Correct Answer is B

Explanation

A. Brain natriuretic peptide (BNP) test: BNP is a biomarker primarily used to assess heart failure and fluid overload, not for detecting early myocardial injury. While BNP levels can be elevated in heart failure or other cardiac conditions, they are not specific for myocardial infarction (MI) or early cardiac muscle injury.

B. Creatine kinase-myocardial band (CK-MB) test: CK-MB is an enzyme found in cardiac muscle that rises in the blood when there is damage to the heart muscle. It is specific to myocardial injury and increases early (within a few hours) after a myocardial infarction. CK-MB is commonly used to detect and assess the extent of heart damage.

C. Troponin T test: While troponin T is a highly sensitive and specific biomarker for cardiac muscle injury and is often used to detect myocardial infarctions, it tends to rise later than CK-MB. Troponin levels remain elevated longer and are considered the gold standard for diagnosing myocardial injury, but CK-MB may identify early injury more quickly.

D. Creatine kinase (CK) test: The CK test measures total creatine kinase, which is found in various tissues, including skeletal muscle, brain, and cardiac muscle. Although it is elevated after myocardial injury, it is less specific to the heart compared to CK-MB, as other tissues may contribute to elevated levels

A. be able to crush the sustained release tablet because of my difficulty swallowing B. take pyridostigmine 30-60 minutes before meals to improve muscle function for chewing and swallowing C. use pyridostigmine only as needed to relieve symptoms of muscle weakness and fatigue. D. double a dose if I have increased fatigue to increase the effects of the medication."

Correct Answer is B

Explanation

A. Crushing sustained-release tablets is not recommended because doing so could interfere with the controlled release of the medication, which is designed to release slowly over time. This could lead to adverse effects.

B. Pyridostigmine is used to improve muscle strength in patients with Myasthenia Gravis (MG). Taking it 30-60 minutes before meals helps maximize its effect on muscle strength, particularly for activities like chewing and swallowing, which are often affected by MG.

C. Pyridostigmine is typically used regularly, not just as needed. Consistent dosing helps maintain muscle strength and manage the symptoms of MG, rather than only addressing occasional weakness and fatigue.

D. Doubling the dose without medical advice can be dangerous. The prescribed dose should be followed, and any changes should be discussed with a healthcare provider to avoid potential overdose or side effects.
