Correct Answer is B

Explanation

A. Ischemia: Ischemia refers to the lack of blood flow to tissues, which can lead to tissue damage or death, but it is not related to swelling due to fluid accumulation.
B. Edema: Edema is the correct term for tissue swelling caused by the accumulation of interstitial fluids, making this the correct choice.
C. Infarction: Infarction refers to tissue death due to a lack of blood supply, not to swelling caused by fluid accumulation.
D. Gangrene: Gangrene is the death of body tissue due to a lack of blood flow or severe infection, not related to fluid accumulation and swelling.

A. Obtain a regular referral. B. Have the patient obtain a second opinion. C. Initiate a referral to a different cardiologist. D. Send the patient to the emergency department for evaluation.

Correct Answer is A

Explanation

A. Obtain a regular referral: If the cardiologist consultation has not been initiated, the medical assistant should obtain or process the referral to ensure the patient sees the specialist as required.
B. Have the patient obtain a second opinion: This action is unnecessary and might be premature if the original referral was not processed.
C. Initiate a referral to a different cardiologist: There is no need to refer to a different cardiologist unless there is a specific issue with the initial referral or cardiologist.
D. Send the patient to the emergency department for evaluation: Sending the patient to the emergency department is not appropriate unless the patient has an urgent issue. The issue here is with the referral process, not an emergency.
