Final answer:
The nurse would anticipate that the health care provider will recommend discontinuing cimetidine due to potential drug interactions with chloroquine and order regular monitoring of liver function while the patient is on these medications.
Step-by-step explanation:
Based on the information provided, the nurse would anticipate that the health care provider will recommend discontinuing cimetidine due to potential drug interactions when it is prescribed with chloroquine. This is because cimetidine can inhibit the metabolism of chloroquine, leading to increased levels of chloroquine in the body and potentially increasing the risk of side effects.
In order to ensure patient safety, it is important to monitor liver function while the patient is on these medications. Therefore, the correct answer would be B) The health care provider will order regular monitoring of liver function while the patient is on these medications.
