A nurse is caring for a client who is experiencing an increase in intracranial pressure (ICP). The nurse should expect which of the following as an early manifestation of increased ICP?

Choice A reason: The Mantoux skin test, also known as the tuberculin skin test, measures the immune response to the tuberculin purified protein derivative injected into the skin. An induration of less than 1 mm is not considered a positive result. However, the size of the induration in the Mantoux test does not indicate whether the person is infectious or not.

Choice B reason: Negative sputum cultures for acid-fast bacillus (AFB) are a strong indication that the client is no longer infectious. Pulmonary tuberculosis is diagnosed and monitored by the presence of AFB in the sputum. When the sputum cultures are negative, it suggests that the client is not excreting the bacteria and is less likely to spread the infection to others.

Choice C reason: While no longer coughing up blood-tinged sputum is a sign of clinical improvement, it does not necessarily mean that the client is no longer infectious. The absence of blood in the sputum may indicate reduced inflammation or healing of lung tissue, but the client could still be capable of transmitting tuberculosis if AFB is present in the sputum.

Choice D reason: The Quantiferon-TB Gold test is a blood test that measures the immune response to Mycobacterium tuberculosis antigens. A positive result indicates that the person's immune system has been exposed to the bacteria, but it does not determine if the person is infectious. The term "positive (negative)" is contradictory and does not provide clear information about the client's infectious status.

Choice A reason: A client with diabetes mellitus presenting with acute ketoacidosis does not necessarily require a private room unless there are other infection control concerns. Diabetic ketoacidosis (DKA) is a serious complication of diabetes that occurs when the body produces high levels of blood acids called ketones. It is a medical emergency that requires treatment in a hospital, but it is not contagious.

Choice B reason: An older adult client admitted with aspiration pneumonia would not typically require a private room solely based on this condition. Aspiration pneumonia is caused by inhaling food, stomach acid, or saliva into the lungs. It can lead to a bacterial infection, which may or may not be contagious depending on the causative organism.

Choice C reason: A client with a compound fracture of the right femur would not require a private room based on the diagnosis alone. A compound fracture, also known as an open fracture, is a fracture in which there is an open wound or break in the skin near the site of the broken bone. While it requires immediate medical attention to prevent infection, it is not a condition that necessitates isolation.

Choice D reason: A client who reports having fever, night sweats, and cough for 2 days may require a private room due to the possibility of an infectious disease that could be transmitted to others, such as tuberculosis (TB). These symptoms are concerning for TB, which is an airborne infectious disease and would require airborne precautions, including a private room with negative pressure ventilation.
