A nurse is preparing a client for a scheduled Percutaneous Coronary Intervention (PCI). Which statement made by the client should the nurse report to the Primary Healthcare Provider (PHCP)?
A “I am allergic to shellfish.”.
B “I may feel a warm sensation during the procedure.”.
C “I get anxious when I am in closed spaces.”.
D “I took my metformin this morning.”.
The Correct Answer and Explanation is:
The correct answer is D: “I took my metformin this morning.”.
Explanation
Percutaneous Coronary Intervention (PCI), which includes procedures such as angioplasty and stenting, often involves the administration of contrast dye to visualize coronary arteries. The use of contrast dye is a critical aspect of PCI but can have significant implications for clients with certain health conditions, particularly those taking medications like metformin.
Metformin is a common medication used to manage type 2 diabetes. However, one of the major concerns with metformin and contrast dye is the risk of a condition known as lactic acidosis, which is a rare but serious complication. This condition can occur when lactic acid builds up in the bloodstream faster than it can be removed, and the use of contrast dye in clients who have recently taken metformin increases this risk.
The combination of metformin and contrast dye can be particularly dangerous for patients with impaired renal function. Contrast agents can affect kidney function, and since metformin is primarily eliminated through the kidneys, impaired renal function or compromised kidney health from the contrast dye can lead to a dangerous accumulation of metformin in the body. This can increase the risk of lactic acidosis. Therefore, it is essential to inform the Primary Healthcare Provider (PHCP) if the client has taken metformin before the PCI.
In contrast, the other statements made by the client are less urgent:
- A “I am allergic to shellfish.”: While this is relevant information because some contrast dyes used in PCI are iodine-based, shellfish allergies are not directly related to the contrast dye used in PCI. However, the nurse should document this information and ensure that the type of contrast used is appropriate.
- B “I may feel a warm sensation during the procedure.”: It is normal for patients to experience a warm sensation when contrast dye is injected. This is a common and expected part of the procedure.
- C “I get anxious when I am in closed spaces.”: This is an important concern for the nurse to address to help manage the patient’s anxiety, but it does not have the same immediate implications for the PCI procedure as the concern related to metformin.
Therefore, reporting that the client took their metformin this morning is crucial for patient safety and effective management of the procedure.
