Lactulose is ordered for a patient with liver disease. What would indicate the medication is exerting a positive therapeutic effect on the patient?

A.

Decreased ascites

B.

Decreased ammonia level

C.

Decreased jaundice

D.

Decreased blood pressure,

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is A

Explanation

A. Headache, dizziness, and fatigue

Ondansetron (Zofran) is commonly used to control nausea and vomiting associated with chemotherapy. While it is generally well-tolerated, some common side effects may include headache, dizziness, and fatigue.

B. Anorexia and hair loss

Anorexia (loss of appetite) and hair loss are not commonly associated with ondansetron. These symptoms may be side effects of chemotherapy itself, but they are not typically attributed to ondansetron.

C. Abdominal cramping and irritability

Abdominal cramping and irritability are not common side effects of ondansetron. These symptoms may be related to other factors, but they are not typically associated with this antiemetic medication.

D. Psychosis and middle ear disturbances

Psychosis and middle ear disturbances are not common side effects of ondansetron. These symptoms may be associated with other medications or conditions, but they are not typically attributed to ondansetron.

Correct Answer is ["36"]

Explanation

To calculate the infusion time for an IV of 1,500 mL running at 25 gtt/min. if the drop factor is 15 gtt/mL, we need to use the following formula:

Infusion time (in minutes) = Volume (in mL) x Drop factor (in gtt/mL) / Flow rate (in gtt/min)

Plugging in the given values, we get:

Infusion time = 1,500 x 15 / 25

Infusion time = 900 / 25

Infusion time = 36

Therefore, the infusion time for this IV is 36 minutes.
