Which vitamin will reduce the therapeutic effects of levodopa?

Answer and Explanation

The Correct Answer is A

A. B6 (Pyridoxine):

Vitamin B6, also known as pyridoxine, is known to reduce the therapeutic effects of levodopa. It competes with levodopa for absorption in the gastrointestinal tract and can decrease the amount of levodopa that reaches the brain, thereby diminishing its effectiveness in treating Parkinson's disease symptoms.

B. A (Retinol):

Vitamin A, also known as retinol, is not typically associated with reducing the therapeutic effects of levodopa. Vitamin A plays important roles in vision, immune function, and cellular communication, but it does not interact with levodopa in a way that affects its therapeutic efficacy.

C. E (Alpha-Tocopherol):

Vitamin E, also known as alpha-tocopherol, is an antioxidant that plays a role in protecting cells from oxidative damage. While vitamin E supplementation is sometimes used in Parkinson's disease management for its potential neuroprotective effects, it is not known to reduce the therapeutic effects of levodopa.

D. K (Phylloquinone):

Vitamin K, also known as phylloquinone, is primarily involved in blood clotting and bone metabolism. It does not interact with levodopa in a way that reduces its therapeutic effects.

E. C (Ascorbic Acid):

Vitamin C, also known as ascorbic acid, is not known to reduce the therapeutic effects of levodopa. While vitamin C has various roles in the body, including antioxidant activity and immune function support, it does not interfere with levodopa absorption or efficacy.

Correct Answer is B

Explanation

A. Fresh fish

Fresh fish does not contain significant amounts of tyramine. Therefore, there is no need to eliminate fresh fish from the client's diet due to its interaction with selegiline.

B. Cheddar cheese

This is the correct answer. Cheddar cheese is a high-tyramine food and should be eliminated from the client's diet when taking MAOIs. Aged cheeses, such as cheddar, contain high levels of tyramine due to the fermentation process, which can increase the risk of a hypertensive crisis when combined with MAOIs.

C. Cherries

Cherries do not contain significant amounts of tyramine. Therefore, there is no need to eliminate cherries from the client's diet due to their interaction with selegiline.

D. Chicken

Chicken does not contain significant amounts of tyramine. Therefore, there is no need to eliminate chicken from the client's diet due to its interaction with selegiline.

A. Perform passive range of motion on each extremity. B. Monitor the client's electrolyte levels. C. Suction saliva from the client's mouth. D. Record the client's intake and output.

Correct Answer is C

Explanation

A. Perform passive range of motion on each extremity:

While passive range of motion exercises are important for preventing contractures and maintaining joint mobility in immobilized clients, they are not the highest priority in this situation. Airway management takes precedence over mobility exercises.

B. Monitor the client's electrolyte levels:

Monitoring electrolyte levels is important for overall assessment and management of the client's health, but it is not the highest priority when the client's airway and breathing are compromised.

C. Suction saliva from the client's mouth:

This is the correct answer. Suctioning saliva from the client's mouth helps maintain a clear airway and prevents aspiration. Unconscious clients are at risk for pooling of oral secretions, which can obstruct the airway and lead to respiratory complications.

D. Record the client's intake and output:

While monitoring intake and output is an essential part of nursing care, it is not the highest priority when the client's airway and breathing are compromised.
