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 B
Explanation
Choice A reason: While bulimia can cause gastrointestinal issues, it is not directly linked to the development of peptic ulcers. Peptic ulcers are primarily associated with factors that affect the stomach lining and increase gastric acidity.
Choice B reason: The correct answer is b because the use of nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen is a well-known risk factor for peptic ulcers. NSAIDs can irritate the stomach lining and inhibit the production of protective mucus, leading to ulcer formation.
Choice C reason: Drinking green tea has not been shown to be a risk factor for peptic ulcers. In fact, some studies suggest that green tea may have protective effects on the stomach lining.
Choice D reason: Consuming spicy foods is often believed to cause peptic ulcers, but there is no scientific evidence to support this. Spicy foods may exacerbate symptoms in individuals with existing ulcers, but they do not cause the condition.
Correct Answer is C
Explanation
Choice A reason: Keeping the television on at all times can contribute to overstimulation and confusion for clients with Alzheimer's disease. It is better to have the television on at specific times and choose calming, familiar programs.
Choice B reason: Hanging abstract pictures on the walls can be confusing and disorienting for clients with Alzheimer's disease. Simple, familiar images or family photographs are more helpful in creating a comforting environment.
Choice C reason: The correct answer is c because keeping familiar personal items in the client's room can provide a sense of security and comfort. Familiar objects can help reduce confusion and anxiety in clients with Alzheimer's disease.
Choice D reason: While adequate lighting is important, bright lighting can sometimes cause discomfort or glare. It is better to have soft, consistent lighting that helps the client feel safe and oriented without causing overstimulation.
