A nurse is admitting a client who has meningitis. Which of the following findings should the nurse expect?

Choice A reason: The Mantoux skin test, also known as the tuberculin skin test, measures the immune response to the tuberculin purified protein derivative (PPD) injected under the skin. An induration of less than 1 mm is not necessarily an indication of non-infectiousness; it may indicate a lack of infection or an inadequate immune response. This test does not reflect the current infectious status as it measures a delayed hypersensitivity reaction and can remain positive for life once someone has been exposed to TB or has received the BCG vaccine.

Choice B reason: Negative sputum cultures for acid-fast bacillus are a strong indication that the client is no longer infectious. Pulmonary tuberculosis is diagnosed and monitored through sputum cultures to detect the presence of Mycobacterium tuberculosis. A series of negative cultures typically indicates that the client is not excreting the bacteria and is, therefore, not contagious.

Choice C reason: While the cessation of coughing up blood-tinged sputum is a positive sign of clinical improvement, it does not conclusively indicate that the client is no longer infectious. The absence of blood in the sputum may simply mean that the damage to lung tissues is healing, but the client could still be harboring and potentially spreading TB bacteria.

Choice D reason: The Quantiferon-TB Gold test is a blood test that measures the immune system's response to TB bacteria. A positive result indicates TB infection, but it does not distinguish between latent infection and active disease, nor does it provide information on infectiousness. The parenthetical "negative" is confusing and should be clarified in the context of the test results.

Choice A reason: Administering aspirin is one of the first interventions for a client experiencing acute angina because aspirin has antiplatelet properties that help prevent blood clots, which can reduce the risk of a heart attack.

Choice B reason: Measuring blood pressure is important but not the first action to take. It provides valuable information about the cardiovascular status of the client and can influence further treatment decisions.

Choice C reason: Administering nitroglycerin is a priority action for acute angina as it helps to dilate the coronary arteries and relieve chest pain. However, it is typically administered after aspirin unless contraindicated.

Choice D reason: Initiating IV access is an important step in the management of acute angina, as it allows for the administration of medications and fluids if needed. However, it is not the first action to take during an acute angina episode.
