A patient is ordered bisacodyl (Dulcolax). Before administering the drug, it is most important for the nurse to assess the patient for what?

A. The importance of consuming adequate amounts of water

When instructing a patient who will take psyllium (Metamucil) to treat constipation, it is crucial to emphasize the importance of consuming adequate amounts of water. Psyllium is a bulk-forming laxative that works by absorbing water in the intestines, forming a gel-like mass that helps soften stools and promote bowel movements. Without sufficient water intake, psyllium may cause an obstruction or worsen constipation.

B. The need to monitor for systemic side effects.

Psyllium is generally well-tolerated and is not associated with significant systemic side effects. The primary consideration is ensuring proper hydration.

C. The onset of action of 30-60 minutes after administration.

Psyllium is not a fast-acting laxative. It usually takes a longer time to produce its effects, and patients should not expect an immediate response within 30-60 minutes.

D. The need to use the dry form of psyllium to prevent cramping.

Using the dry form of psyllium is not recommended, as it may increase the risk of choking or swallowing difficulties. It is typically recommended to mix psyllium with a sufficient amount of water or other liquids to prevent cramping and ensure proper absorption.

A. Increase the amount of dopamine and reduce the amount of acetylcholine:

This is the correct answer. Parkinson's disease is characterized by a deficiency of dopamine, so medications aim to increase dopamine levels. Additionally, reducing the activity of acetylcholine helps to restore the balance between these neurotransmitters.

B. Increase the amount of dopamine and acetylcholine:

This is not accurate. Increasing both dopamine and acetylcholine would not address the underlying imbalance seen in Parkinson's disease.

C. Reduce the amount of dopamine and increase the amount of acetylcholine:

This is incorrect. Parkinson's disease involves a reduction in dopamine levels, so reducing dopamine further would worsen the symptoms. Additionally, increasing acetylcholine is not the therapeutic goal in Parkinson's disease.

D. Reduce the amount of dopamine and acetylcholine:

This is not the correct approach. Decreasing both dopamine and acetylcholine would exacerbate the symptoms of Parkinson's disease, as the primary issue is the deficiency of dopamine.
