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."

Answer and Explanation

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: Black-colored stools can indicate gastrointestinal bleeding, which is a potential side effect of corticosteroids like betamethasone. It is not considered harmless and should be reported to the healthcare provider immediately.

Choice B reason: A low-potassium diet is not specifically required for clients taking betamethasone. Corticosteroids can cause potassium loss, so it is important to monitor potassium levels, but not necessarily restrict intake unless directed by the healthcare provider.

Choice C reason: The correct answer is c because taking corticosteroids like betamethasone every other day can help reduce the risk of adrenal suppression, a common side effect of long-term corticosteroid use. This dosing schedule allows the adrenal glands to recover and maintain their function.

Choice D reason: Taking betamethasone before bedtime is not specifically recommended for its effectiveness. The dosing schedule should be based on the healthcare provider's instructions and tailored to the client's condition and response to the medication.

A. Limit fluid intake. B. Monitor client’s cardinal fields of vision. C. Encourage ambulation. D. Ensure the room is brightly lit.

Correct Answer is B

Explanation

Choice A reason: Limiting fluid intake is not an appropriate intervention for labyrinthitis. Adequate hydration is important for overall health and should be maintained.

Choice B reason: The correct answer is b because labyrinthitis can affect the vestibular system, leading to dizziness and vertigo. Monitoring the client’s cardinal fields of vision helps assess for nystagmus, which is a common symptom of vestibular disorders.

Choice C reason: Encouraging ambulation is not advisable for clients with labyrinthitis, as it can increase the risk of falls and injury due to dizziness and imbalance.

Choice D reason: Ensuring the room is brightly lit is not necessary for the management of labyrinthitis and may not provide any therapeutic benefit.
