A nurse is reinforcing teaching with a client who is scheduled for a thallium scan. When talking with the client about this procedure, which of the following statements should the nurse give?
"This test evaluates the heart’s functional capacity."
"This test identifies heart rhythm disturbances."
"This test determines the size of the chambers of the heart."
"This test detects damage to the heart muscle."
The Correct Answer is D
Choice A reason: While a thallium scan can provide information about the heart's functional capacity, it is more specifically used to detect areas of the heart muscle that are not receiving adequate blood supply.
Choice B reason: A thallium scan does not identify heart rhythm disturbances. This is typically evaluated with an electrocardiogram (ECG) or Holter monitor.
Choice C reason: The size of the chambers of the heart is usually assessed through echocardiography or other imaging techniques, not a thallium scan.
Choice D reason: The correct answer is d because a thallium scan detects damage to the heart muscle by identifying areas with reduced blood flow, which may indicate ischemia or previous infarction.

Correct Answer is C
Explanation
Choice A reason: Providing a diet high in protein is not appropriate during the oliguric phase of acute kidney injury, as it can increase the workload on the kidneys and worsen kidney function. Protein intake should be carefully managed based on the client's condition.
Choice B reason: Ibuprofen is contraindicated in clients with acute kidney injury because it can further impair kidney function. Pain management should be approached with alternative medications that do not have nephrotoxic effects.
Choice C reason: The correct answer is c because monitoring intake and output hourly is crucial in managing acute kidney injury. Accurate measurement of fluid balance helps guide treatment decisions and prevent complications such as fluid overload or dehydration.
Choice D reason: Encouraging the client to consume at least 2 L of fluid daily is not appropriate in the oliguric phase, as the kidneys' ability to excrete fluids is impaired. Fluid intake should be carefully restricted and monitored to avoid fluid overload.
Correct Answer is ["A","B","C"]
Explanation
Choice A reason: The correct answer is a because orange juice is high in potassium and should be avoided by clients with chronic kidney disease to prevent hyperkalemia, which can lead to serious cardiac complications.
Choice B reason: The correct answer is b because watermelon, although refreshing, is high in potassium and should be limited or avoided by clients with chronic kidney disease to maintain safe potassium levels.
Choice C reason: The correct answer is c because bananas are well-known for their high potassium content and should be avoided by clients with chronic kidney disease to prevent elevated potassium levels in the blood.
Choice D reason: Corn flakes cereal is generally low in potassium and is not a food that needs to be avoided in clients with chronic kidney disease. It can be included in their diet in moderation.
Choice E reason: White rice is also low in potassium and can be safely consumed by clients with chronic kidney disease. It does not pose a significant risk of increasing potassium levels.
