A nurse is caring for a client who has a new diagnosis of amyotrophic lateral sclerosis (ALS), and a new prescription for riluzole. The nurse understands that this medication works in which of the following ways?

It suppresses the virus which is responsible for causing the inflammation of the nerve.

It prevents the breakdown of acetylcholine to increase the amount available at the neuromuscular junction.

It reduces inflammation in the CNS to prevent further demyelination of nerves in the central nervous system.

It slows the progression of the disease by decreasing the release of glutamate in the brain.

Answer and Explanation

The Correct Answer is D

A.   ALS is not caused by a virus or inflammation of the nerves. It is a progressive neurodegenerative disease affecting the motor neurons in the brain and spinal cord.
B.   While acetylcholine breakdown is involved in other neurological conditions (such as myasthenia gravis), ALS primarily affects motor neurons and does not directly involve acetylcholine metabolism at the neuromuscular junction.
C.   ALS does not typically involve significant inflammation or demyelination (which is more characteristic of conditions like multiple sclerosis). Therefore, reducing CNS inflammation is not a therapeutic target in ALS.
D.   Riluzole, the medication prescribed for ALS, works by decreasing the release of glutamate, which is a neurotransmitter that can be toxic to nerve cells in high amounts. In ALS, excessive glutamate release is believed to contribute to motor neuron degeneration. By reducing glutamate release, riluzole may help protect motor neurons and slow the progression of the disease.

Correct Answer is C

Explanation

A. Medicare does cover individuals under 65 years old who have end-stage renal disease (ESRD) and meet certain criteria.
B. There are programs that allow individuals with both Medicare and low income to qualify for Medicaid, which can help cover additional healthcare costs that Medicare may not fully cover.
C. While Medicare does provide significant coverage for healthcare services, it is not entirely free of out- of-pocket costs. Medicare Part A typically covers hospital stays, skilled nursing facility care, hospice, and some home health care services with no premiums for most people.
D. Medicare is indeed federally-funded health insurance primarily for individuals aged 65 and older. It also covers certain younger individuals with disabilities and those with ESRD.

A. Leave the affected area open to air when you are at home. B. Limit ice-pack application to the area to 20 minutes at a time. C. Lubricate the area with an alcohol-based lotion. D. You may use aloe vera gel on the affected skin. E. Clean the area with betadine to prevent infection.

Correct Answer is ["A","D"]

Explanation

A. Allowing the affected skin to be exposed to air can help in promoting healing and preventing further irritation. However, it's essential to ensure the environment is clean and that the area is protected from friction and contamination.
B. Ice packs should be avoided as they can cause further irritation to the radiated skin, and alcohol- based lotions can be drying and may exacerbate skin reactions.

C. Alcohol-based lotions can be drying and irritating to sensitive, radiation-treated skin. It's preferable to use gentle, non-alcohol-based moisturizers or barrier creams that are specifically designed for sensitive skin. These can help soothe the skin and prevent excessive dryness and irritation.
D. Aloe vera gel is known for its soothing and moisturizing properties, which can help alleviate discomfort and promote healing of radiation-damaged skin. It is gentle and generally well-tolerated by most individuals.
E. Betadine (povidone-iodine) can be too harsh for radiation-damaged skin and may further irritate the area. Gentle cleansing with mild soap and water is recommended to keep the area clean and minimize the risk of infection.
