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: Injecting the medication into the abdomen above the level of the iliac crest is not recommended. The preferred sites for subcutaneous injections are the fatty tissue over the triceps, the abdomen from below the costal margin to the iliac crests, and the anterior aspects of the thighs. The area above the iliac crest may not have sufficient subcutaneous tissue, which could affect the absorption of the medication.

Choice B reason: Using a 1-inch needle can be appropriate depending on the client's body mass. For most adults, a 5/8-inch to 1-inch needle is recommended for subcutaneous injections to ensure the medication is delivered to the subcutaneous tissue and not into the muscle.

Choice C reason: Using a 25-gauge needle is the appropriate action when administering heparin subcutaneously. A smaller gauge needle, such as 25-gauge, is typically used for subcutaneous injections to minimize discomfort and tissue trauma.

Choice D reason: Massaging the injection site after administration of the medication is not recommended when administering heparin subcutaneously. Massaging the site can cause the medication to be absorbed more quickly than intended and may increase the risk of bleeding.
