A health care provider prescribes 50 mg of a drug. The drug is only available in a 20 mL vial that contains 20 mg/mL of the drug. How much solution must the nurse administer for each dose?
The Correct Answer is ["2.5"]
To calculate the amount of solution needed for each dose, we need to use the formula:
Amount of solution (mL) = Dose (mg) / Concentration (mg/mL)
Plugging in the given values, we get:
Amount of solution (mL) = 50 mg / 20 mg/mL
Simplifying, we get:
Amount of solution (mL) = 2.5 mL
Therefore, the nurse must administer 2.5 mL of the solution for each dose.

Correct Answer is ["40"]
Explanation
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 B
Explanation
A. Decreased ascites
Ascites (accumulation of fluid in the abdominal cavity) is more directly related to portal hypertension and liver cirrhosis. While lactulose may contribute to fluid balance, its primary therapeutic effect in hepatic encephalopathy is the reduction of ammonia levels.
B. Decreased ammonia level
Lactulose is a medication commonly used in the treatment of hepatic encephalopathy, a condition associated with liver disease. The therapeutic effect of lactulose in this context is to reduce blood ammonia levels. Lactulose works by promoting the excretion of ammonia in the form of ammonium ions in the colon, thereby lowering ammonia concentrations in the blood.
C. Decreased jaundice
Jaundice is often associated with liver dysfunction, but lactulose is not primarily used to address jaundice. Its primary role in liver disease is in the management of hepatic encephalopathy.
D. Decreased blood pressure
Blood pressure is not a direct therapeutic target of lactulose in the context of liver disease. Lactulose's primary therapeutic effect is related to reducing ammonia levels and managing hepatic encephalopathy.
