A nurse is providing breast self-examination teaching to a client who is menopausal. Which of the following statements should the nurse identify as an indication that the teaching was effective? (Select all that apply.)

Choice A reason:
The Mantoux test, also known as the tuberculin skin test, is used to detect latent TB infection but is not the most reliable for confirming active pulmonary TB. It can indicate if someone has been infected with TB bacteria, but it cannot differentiate between latent and active TB.

Choice B reason:
A sputum culture for acid-fast bacillus is the gold standard for diagnosing active pulmonary TB. It involves culturing a sample of sputum (phlegm) to see if TB bacteria grow, which confirms the diagnosis. This test is the most definitive and reliable method, although it may take several weeks to obtain results.

Choice C reason:
A sputum smear can detect TB bacteria in sputum samples quickly, but it is less sensitive than a culture. It can miss cases, especially if the bacterial load is low. Therefore, while useful for initial screening, it is not as reliable as a culture for confirming active TB.

Choice D reason:
A chest x-ray can show signs suggestive of TB, such as infiltrates or cavities in the lungs, but it cannot confirm the presence of TB bacteria. It is a supportive diagnostic tool but not definitive for active TB diagnosis.

Choice A reason:
Clay-colored stools are typically associated with issues in the biliary system, such as bile duct obstruction, and not directly with aspirin use. Aspirin, especially when used in high doses, is more commonly associated with gastrointestinal side effects like bleeding, which would likely cause dark or bloody stools rather than clay-colored ones.

Choice B reason:
Nystagmus, which is a vision condition characterized by repetitive, uncontrolled eye movements, is not a recognized side effect of aspirin. While aspirin can have effects on various systems in the body, it does not typically affect the muscles or nerves controlling eye movements.

Choice C reason:
Tinnitus, or ringing in the ears, is a well-documented adverse effect of aspirin, particularly when taken in high doses or for a prolonged period. It is related to the effect of aspirin on the inner ear structures and is usually reversible once the medication is stopped or the dosage is reduced.

Choice D reason:
Respiratory depression is not a typical side effect of aspirin. Aspirin can cause respiratory alkalosis in cases of overdose due to hyperventilation, but it does not cause respiratory depression. If respiratory depression occurs, it would likely be due to a different cause and not the aspirin itself.
