A 10-year-old child will be receiving docusate sodium (Colace), 120 mg/day PO, divided into 3 doses. How many milligrams will the child receive per dose?
The Correct Answer is ["40"]
To calculate the dosage of docusate sodium (Colace) for a 10-year-old child, we need to divide the total amount of medication by the number of doses. The total amount of medication is 120 mg/day, and the number of doses is 3. Therefore, we can use the following formula:
Dosage per dose = Total amount / Number of doses
Dosage per dose = 120 mg / 3
Dosage per dose = 40 mg
The child will receive 40 mg of docusate sodium (Colace) per dose, three times a day.

Correct Answer is A
Explanation
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.
Correct Answer is C
Explanation
A. Parkinson's disease
Edrophonium is not used for the diagnosis of Parkinson's disease. Parkinson's disease is a neurodegenerative disorder characterized by motor symptoms such as tremors, rigidity, and bradykinesia. The diagnosis is typically based on clinical symptoms and neurological examination.
B. Alzheimer's disease
Edrophonium is not used for the diagnosis of Alzheimer's disease. Alzheimer's disease is a progressive neurodegenerative disorder affecting cognition. The diagnosis involves clinical evaluation, cognitive assessments, and sometimes imaging studies, but not the use of edrophonium.
C. Myasthenia Gravis
This is the correct choice. Edrophonium is used as a diagnostic tool in Myasthenia Gravis. In individuals with Myasthenia Gravis, the administration of edrophonium can lead to a temporary improvement in muscle strength, helping to confirm the diagnosis.
D. Serotonin Syndrome
Edrophonium is not used for the diagnosis of serotonin syndrome. Serotonin syndrome is a condition caused by an excess of serotonin, often due to the use of certain medications. Diagnosis is based on clinical symptoms and a history of serotonin-affecting medications, not the administration of edrophonium.
