Which vitamin will reduce the therapeutic effects of levodopa?
B6
A
E
K
C
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 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.
Correct Answer is C
Explanation
A. Check the client for a fecal impaction.
This intervention is important for managing autonomic dysreflexia because a fecal impaction can trigger autonomic dysreflexia by causing rectal distention. However, it is not the first action the nurse should take. Promptly addressing the immediate cause of autonomic dysreflexia is crucial to prevent complications.
B. Ensure the room temperature is warm.
This intervention is important for maintaining the client's comfort and preventing temperature-related complications. However, it is not the first action the nurse should take when suspecting autonomic dysreflexia. Immediate interventions to address the underlying cause of autonomic dysreflexia are necessary to prevent serious complications such as stroke or seizure.
C. Check the client's bladder for distention.
This is the correct action to take first. Bladder distention is one of the most common triggers of autonomic dysreflexia in individuals with spinal cord injuries. A distended bladder stimulates autonomic reflexes, leading to a sudden increase in blood pressure. Therefore, the nurse should assess the client's bladder for distention and initiate appropriate interventions such as catheterization to relieve urinary retention.
D. Raise the head of the bed.
While elevating the head of the bed can help reduce blood pressure in some situations, it is not the first action the nurse should take when suspecting autonomic dysreflexia. Elevating the head of the bed may exacerbate autonomic dysreflexia by increasing venous return and blood pressure. Therefore, addressing the underlying cause of autonomic dysreflexia, such as bladder distention, takes priority.
