Which medication is commonly used in the treatment of multiple sclerosis?

Pyridostigmine

Levodopa-carbidopa

Riluzole

Interferon-beta

Answer and Explanation

The Correct Answer is D

A.   Pyridostigmine is primarily used in the treatment of myasthenia gravis, a different autoimmune neuromuscular disorder characterized by weakness of voluntary muscles. It works by inhibiting the

enzyme acetylcholinesterase, which increases the levels of acetylcholine at neuromuscular junctions, thereby improving muscle strength. It is not used for treating multiple sclerosis.
B.   Levodopa-carbidopa is commonly used to treat Parkinson’s disease. Levodopa is converted to dopamine in the brain, and carbidopa prevents levodopa from being converted into dopamine before it reaches the brain. This combination helps manage the motor symptoms of Parkinson’s disease. It is not used for multiple sclerosis.
C.   Riluzole is used primarily for the treatment of amyotrophic lateral sclerosis (ALS), a neurodegenerative disease affecting motor neurons. It works by reducing the release of glutamate, a neurotransmitter that can be toxic to nerve cells. Riluzole is not used for multiple sclerosis.
D.   Interferon-beta is a disease-modifying therapy used in the treatment of multiple sclerosis. It works by modulating the immune system to reduce the frequency and severity of MS relapses. Interferon-beta can help slow the progression of disability and reduce the number of new lesions seen on MRI scans.

Correct Answer is B

Explanation

A. Automatically switching to liquid nutrition without assessing the client’s tolerance and needs may not be the most appropriate first step. It’s important to consider the client’s preferences, nutritional requirements, and overall ability to tolerate different types of food.
B. This is a highly appropriate and commonly recommended intervention for clients experiencing nausea and weight loss due to chemotherapy. Small, frequent meals can help manage nausea better than large meals and ensure a more consistent intake of calories and nutrients.
C. Eating one large meal per day is generally not advisable for clients with nausea, as it can exacerbate feelings of fullness and discomfort. Large meals may increase nausea and make it more difficult for the client to consume adequate nutrients. Small, frequent meals are generally better tolerated and more effective for managing nausea and ensuring consistent nutrient intake.
D. Inserting a nasogastric (NG) tube and administering tube feedings is a more invasive measure and is usually considered only if oral intake is severely compromised and other interventions have been ineffective. Tube feedings are appropriate for clients who cannot meet their nutritional needs through oral intake due to severe nausea, vomiting, or other conditions.

A. The procedure uses electrical energy to destroy areas of the conduction system. B. The procedure uses cold therapy to stop the formation of the flutter waves. C. The procedure removes clots which have formed in the atria. D. The procedure stimulates the growth of new conduction pathways between the atria.

Correct Answer is A

Explanation

A. Radiofrequency catheter ablation involves the use of electrical energy (radiofrequency energy) delivered through a catheter to destroy or ablate the areas of the heart tissue responsible for the abnormal electrical signals causing atrial flutter. This destruction of tissue helps to interrupt the abnormal electrical pathways and restore normal rhythm.
B. The procedure for atrial flutter ablation does not use cold therapy. Instead, it uses radiofrequency energy (heat) to ablate the tissue. Cold therapy, or cryoablation, is a different technique that uses extreme cold to achieve similar effects but is not the standard approach for radiofrequency catheter ablation.
C. Radiofrequency catheter ablation does not involve removing clots. The primary purpose of the procedure is to ablate abnormal tissue causing arrhythmias, not to address clots. Managing clots may involve anticoagulant therapy or other treatments, but it is not the focus of ablation.
D. Radiofrequency catheter ablation does not stimulate the growth of new conduction pathways. Instead, it aims to destroy the abnormal conduction pathways responsible for arrhythmias.
