A nurse is reviewing the laboratory results of a client who is taking furosemide and notes the client's potassium level is 3.0 mEq/L. Which of the following physiological responses should the nurse expect related to the client's hypokalemia?

A. A patient with coronary artery disease (CAD) who reports chest pain radiating to the jaw: This patient should be evaluated first. Chest pain radiating to the jaw can be a sign of a heart attack, which is a life-threatening condition. Immediate medical attention is required to prevent further damage to the heart muscle.

B. A patient with venous insufficiency with 2+ pitting edema: While this patient’s condition needs to be addressed, it is not as immediately life-threatening as a potential heart attack. Venous insufficiency and edema can lead to discomfort and complications if left untreated, but these complications are typically not immediate.

C. A patient receiving enoxaparin (Lovenox) for experiencing an MI 3 days ago: This patient is already receiving treatment for their condition. While they should be monitored for side effects of the medication and signs of further cardiac issues, they are not the highest priority based on the information given.

D. A patient with peripheral artery disease (PAD) with a diminished pulse: While a diminished pulse can indicate poor blood flow, which can lead to complications such as tissue damage and non-healing wounds, it is not as immediately life-threatening as a potential heart attack. This patient should be evaluated, but they are not the highest priority based on the information given.

(A) Evaluating the collected data: This step involves analyzing the data that has been collected during the research process. However, in this scenario, the nurse is in the process of researching data, which suggests that the data collection phase is still ongoing.

(B) Searching for credible sources: This is the most appropriate answer. The nurse is in the process of researching data about best practices for reducing medication errors. This indicates that the nurse is currently searching for credible sources of information, which is a crucial step in the EBP process.

(C) Implementing recommendations: This step involves applying the findings from the research to practice. However, in this scenario, the nurse is still in the research phase, so implementation has not yet occurred.

(D) Identifying a problem: While identifying a problem is an important step in the EBP process, in this scenario, the problem (medication errors on a surgical unit) has already been identified. The nurse is now in the process of researching data, which suggests that the problem identification step has already been completed.
