A patient is ordered a phenothiazine antiemetic for treatment of nausea and vomiting associated with chemotherapy. The nurse will be evaluating for a positive effect. At what time should the nurse administer the drug?

as requested by the patient.

1 hour after chemotherapy administration.

The night before the treatment, the day of the treatment, and for 24 hours after the treatment.

the day of treatment.

Answer and Explanation

The Correct Answer is C

A. As requested by the patient.

Administering the drug only when requested by the patient may not provide adequate prophylaxis against chemotherapy-induced nausea and vomiting. These medications are often prescribed on a schedule to prevent symptoms rather than treating them reactively.

B. 1 hour after chemotherapy administration.

Waiting until 1 hour after chemotherapy administration may not cover the full period during which nausea and vomiting are likely to occur. The administration schedule for antiemetics is often more extended to provide better coverage.

C. The night before the treatment, the day of the treatment, and for 24 hours after the treatment.

This is the correct choice. Administering phenothiazine antiemetics according to this schedule helps ensure continuous coverage during the critical period when chemotherapy-induced nausea and vomiting are most likely to occur.

D. The day of treatment.

Administering the drug only on the day of treatment may not provide sufficient coverage for the entire duration when chemotherapy-induced nausea and vomiting can occur. Again, the schedule mentioned in option C is more comprehensive for prevention.

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.

A. "You will need to take an anticonvulsant of some type for your lifetime." B. "This medication should be taken until you haven't had a seizure for a month." C. "Seizures are unpredictable and so is the duration of the treatment." D. "You will only need to take it for a short period of time because anticonvulsants will cure the seizure disorder."

Correct Answer is C

Explanation

A. "You will need to take an anticonvulsant of some type for your lifetime."

This statement may be accurate for some individuals with chronic or recurrent seizure disorders, but it is a generalization. The duration of anticonvulsant therapy varies from person to person, and some individuals may eventually be able to discontinue medication under the guidance of their healthcare provider.

B. "This medication should be taken until you haven't had a seizure for a month."

While seizure control is a factor in determining the duration of treatment, setting a specific timeframe (e.g., one month) may not be applicable to everyone. The decision to continue or discontinue anticonvulsant therapy is usually individualized and based on various factors, including the type of seizure disorder and the individual's response to treatment.

C. "Seizures are unpredictable and so is the duration of the treatment."

This is the best response. It acknowledges the variability in seizure disorders and the individualized nature of treatment duration. Seizure management is often an ongoing process that requires monitoring and adjustments based on the person's specific circumstances.

D. "You will only need to take it for a short period of time because anticonvulsants will cure the seizure disorder."

Anticonvulsants are typically used to manage and control seizures rather than cure the underlying seizure disorder. While some individuals may experience a period of seizure freedom and be able to discontinue medication, this is not true for everyone. The duration of treatment varies, and some individuals may require long-term or even lifelong therapy.
