What is the appropriate action to take if a client has a known allergy to IV dye used in CT scans?

Administer the IV dye and closely monitor the client for any allergic reactions

Administer a small test dose of the IV dye to determine if the client has a reaction

Notify the healthcare provider and radiology department about the client's allergy

Continue with the CT scan as scheduled since IV dye allergies are rare and unlikely to occur

Answer and Explanation

The Correct Answer is C

Choice a reason: Administering the IV dye and closely monitoring the client for any allergic reactions is not the appropriate action. If the client has a known allergy to the dye, administering it can provoke a severe allergic reaction, including anaphylaxis, which can be life-threatening. Preemptively administering the dye without addressing the allergy can lead to significant risk for the patient and is not recommended.
Choice b reason: Administering a small test dose of the IV dye to determine if the client has a reaction is also inappropriate. A known allergy to IV dye should not be tested in this way, as even a small amount can trigger an allergic response. Allergic reactions to IV dye can be severe and testing the reaction is not a safe or effective approach.
Choice c reason: Notifying the healthcare provider and radiology department about the client's allergy is the appropriate action. This ensures that alternative imaging techniques or different contrast agents can be used to avoid triggering an allergic reaction. This step is essential for ensuring patient safety and effective care.
Choice d reason: Continuing with the CT scan as scheduled since IV dye allergies are rare and unlikely to occur is incorrect. If a client has a known allergy, disregarding this and proceeding with the scan poses a significant risk. Even if such allergies are rare, they can be severe, and patient safety protocols must be followed to prevent harm.

Correct Answer is C

Explanation

Choice a reason: Maintaining IV fluids and encouraging oral fluids is important for patients with renal colic to ensure hydration and facilitate the passage of kidney stones. However, it is not the most immediate action to take for managing the patient's current condition, which includes severe pain and hematuria.
Choice b reason: Promoting assisted ambulation as tolerated can help in the movement and passage of kidney stones. Nevertheless, it is not the priority action to take initially when the patient is experiencing severe pain and there is a need to identify the cause of the hematuria.
Choice c reason: Straining urinary output and observing for stones is the most appropriate initial action. This allows the nurse to collect any stones that pass, which can then be analyzed to determine their composition. Understanding the type of stone can help in planning further treatment and preventive measures. Identifying and collecting the stones is crucial for proper diagnosis and management of renal colic.
Choice d reason: Administering prescribed narcotic medication is essential for managing severe pain associated with renal colic. Pain management is a critical component of care. However, while it is necessary, it should be accompanied by straining the urine to detect any stones and understand the underlying cause of the symptoms.

A. Simvastatin B. Pantoprazole C. Valsartan D. Metformin

Correct Answer is D

Explanation

Choice a reason: Simvastatin, a statin medication used to control high cholesterol, does not typically interact with IV contrast dye. There is no need to withhold simvastatin before radiological studies involving contrast dye. The primary concern with simvastatin is monitoring for potential side effects, such as muscle pain and liver function, but these are not directly related to contrast dye use.
Choice b reason: Pantoprazole, a proton pump inhibitor used to reduce stomach acid, does not have known interactions with IV contrast dye. It can be safely continued before, during, and after radiological studies involving contrast. The main considerations with pantoprazole are related to its effect on stomach acid and potential side effects like headaches or gastrointestinal issues.
Choice c reason: Valsartan, an angiotensin II receptor blocker used to manage hypertension, does not interact with IV contrast dye. There is no need to withhold valsartan before undergoing radiological studies with contrast. Valsartan is primarily concerned with managing blood pressure and may have side effects such as dizziness or increased potassium levels, but these are not influenced by contrast dye.
Choice d reason: Metformin, an oral hypoglycemic agent used to manage type 2 diabetes, should be withheld prior to radiological studies with IV contrast dye. There is a risk of lactic acidosis, a rare but serious complication, when metformin is combined with contrast dye. To reduce this risk, metformin should be withheld for at least 48 hours before and after the procedure, and renal function should be monitored closely. This precaution helps ensure the safety of clients undergoing radiological studies with contrast dye.
