A nurse is collecting a medication history from a client who is scheduled to have a cardiac catheterization. Which of the following medications taken by the client interacts with contrast material and places the client at risk for acute kidney injury?

Metformin

Carvedilol

Nitroglycerin

Atorvastatin

None

Answer and Explanation

The Correct Answer is A

Choice A: Metformin

Reason: Metformin is known to interact with contrast material, particularly iodinated contrast media, and can increase the risk of acute kidney injury (AKI). This interaction can lead to a condition known as contrast-induced nephropathy (CIN) or contrast-induced acute kidney injury (CI-AKI). Metformin is primarily excreted by the kidneys, and impaired renal function can lead to its accumulation, increasing the risk of lactic acidosis, a rare but serious complication. Therefore, it is generally recommended to withhold metformin before and after the administration of contrast media until renal function is confirmed to be normal.

Choice B: Carvedilol

Reason: Carvedilol is a beta-blocker used to treat high blood pressure and heart failure. It does not have a known interaction with contrast media that would increase the risk of acute kidney injury. Carvedilol primarily affects the cardiovascular system and does not significantly impact renal function or interact with contrast agents.

Choice C: Nitroglycerin

Reason: Nitroglycerin is used to treat angina and other heart conditions by dilating blood vessels. It does not interact with contrast media in a way that would increase the risk of acute kidney injury. Nitroglycerin’s primary effects are on the cardiovascular system, and it does not have nephrotoxic properties.

Choice D: Atorvastatin

Reason: Atorvastatin is a statin used to lower cholesterol levels. While it can have effects on liver enzymes and muscle tissue, it does not interact with contrast media to increase the risk of acute kidney injury. Atorvastatin is metabolized by the liver and does not significantly impact renal function.

Correct Answer is ["A","B","D","E"]

Explanation

Choice A Reason:

Aspirating the stomach contents is essential to ensure the nasogastric tube is correctly positioned in the stomach. This step helps verify that the tube has not migrated and is safe for medication administration. If the aspirate is not obtained, further steps should be taken to confirm the tube’s placement.

Choice B Reason:

Checking the residual volume is important to assess the stomach’s contents and ensure that the patient is tolerating the feedings or medications. High residual volumes may indicate delayed gastric emptying or other gastrointestinal issues. This information helps guide the timing and amount of medication administration.

Choice C Reason:

Removing the tube and placing it in the other nostril is not a standard practice before administering medication. This action is unnecessary and could cause discomfort or complications for the patient. The focus should be on verifying the tube’s placement and ensuring it is functioning correctly.

Choice D Reason:

Testing the stomach contents for a pH indicating acidity is a reliable method to confirm the nasogastric tube’s placement. Gastric contents typically have a pH of 1 to 5, indicating the tube is in the stomach. This step helps ensure the safe administration of medications.

Choice E Reason:

Turning off the suction to the nasogastric tube is necessary before administering medications. Suction can interfere with the absorption of the medication and may cause the medication to be removed from the stomach before it has a chance to take effect. Therefore, it is important to turn off the suction temporarily during medication administration.

A. Assessment: The trachea is shifted away from the midline of the neck. B. Assessment: Pulse oximetry is 93% on 2 L of oxygen. C. Assessment: The client rates pain as 8/10 at the site of the procedure. D. Intervention: Request an order for pain medication. E. Intervention: Measure oxygen saturation before and after a 12-minute walk. F. Intervention: Explain the procedure in detail to the client and the family. G. Intervention: Assist the client to the bathroom. H. Intervention: Discuss all possible complications with the client. I. Assessment: A small amount of drainage from the site is noted. J. Intervention: Validate that informed consent has been given by the client.

Correct Answer is ["A","J"]

Explanation

Intervention: Validate that informed consent has been given by the client.

Reason: Before any invasive procedure, it is crucial to ensure that the client has given informed consent. This means the client understands the procedure, its risks, benefits, and any potential complications. Validating informed consent is a legal and ethical requirement that ensures the client is making an informed decision about their care12.

Assessment: The trachea is shifted away from the midline of the neck.

Reason: A tracheal shift is a critical finding that warrants immediate action. It can indicate a tension pneumothorax, which is a life-threatening condition where air accumulates in the pleural space and causes the lung to collapse. This shift can compromise respiratory function and requires urgent intervention34.

Choice B: Pulse oximetry is 93% on 2 L of oxygen.

Reason: While a pulse oximetry reading of 93% on 2 liters of oxygen is slightly below the normal range (95-100%), it is not immediately life-threatening. However, it does indicate that the client may need further evaluation and monitoring to ensure adequate oxygenation.

Choice C: The client rates pain as 8/10 at the site of the procedure.

Reason: Pain management is important, but an 8/10 pain rating at the procedure site, while significant, does not require immediate action compared to a tracheal shift. Pain can be managed with appropriate analgesics as ordered by the physician.

Choice D: Request an order for pain medication.

Reason: Requesting an order for pain medication is a necessary intervention for managing the client’s pain, but it is not as urgent as addressing a tracheal shift. Pain management should be part of the overall care plan.

Choice E: Measure oxygen saturation before and after a 12-minute walk.

Reason: Measuring oxygen saturation before and after a 12-minute walk is a useful assessment to evaluate the client’s respiratory function and endurance. However, it is not an immediate priority compared to ensuring informed consent and addressing critical findings.

Choice F: Explain the procedure in detail to the client and the family.

Reason: Explaining the procedure in detail to the client and their family is essential for informed consent and reducing anxiety. It ensures that the client understands what to expect and can make an informed decision about their care.

Choice G: Assist the client to the bathroom.

Reason: Assisting the client to the bathroom is a routine nursing intervention that ensures the client’s comfort and dignity. However, it is not a priority compared to addressing critical findings and ensuring informed consent.

Choice H: Discuss all possible complications with the client.

Reason: Discussing all possible complications with the client is part of the informed consent process. It ensures that the client is aware of potential risks and can make an informed decision about their care.

Choice I: A small amount of drainage from the site is noted.

Reason: Noting a small amount of drainage from the site is an important assessment, but it is not as urgent as addressing a tracheal shift. The drainage should be monitored and documented, and any significant changes should be reported to the physician.
