A nurse is preparing a client for intradermal tuberculin skin testing (TST). Which of the following statements should the nurse make?
“An indurated area of 4 millimeters indicates a positive result.”.
“The injection site will be evaluated within 24 hours.”.
“A positive result does not always indicate active disease.”.
“The test will not be administered if you have had a previous negative result.”. .
The Correct Answer is C
Choice A rationale
An indurated area of 4 millimeters is not considered a positive result for tuberculin skin testing. The size of induration considered positive varies based on the individual’s risk factors and health status.
Choice B rationale
The injection site for a tuberculin skin test should be evaluated between 48 and 72 hours after administration, not within 24 hours. Evaluating it too early may not provide accurate results.
Choice C rationale
A positive result in a tuberculin skin test indicates that the person has been infected with TB bacteria, but it does not necessarily mean they have active TB disease. Further tests are needed to determine if the disease is active.
Choice D rationale
A previous negative result does not preclude the administration of a new tuberculin skin test. Individuals can be retested if there is a new risk of exposure or if it is required for medical or occupational reasons.

Correct Answer is D
Explanation
Choice A rationale
While feeling depressed is a significant concern, it is not the highest priority in the context of systemic lupus erythematosus (SLE). Depression should be addressed, but it does not pose an immediate threat to the client’s physical health.
Choice B rationale
Joint pain in hands and knees is a common symptom of SLE but is not the highest priority. It indicates inflammation but does not pose an immediate risk to the client’s overall health.
Choice C rationale
A dry, raised rash on the face, often referred to as a “butterfly rash,” is a characteristic symptom of SLE. However, it is not the highest priority to report as it does not pose an immediate threat.
Choice D rationale
Presence of peripheral edema is the highest priority to report because it can indicate kidney involvement, which is a serious complication of SLE. Kidney damage can lead to significant health issues and requires immediate attention.
Correct Answer is C
Explanation
Choice A rationale
Applying an ice pack to painful joints can help reduce inflammation and numb the area, providing temporary pain relief. However, it is not a recommended long-term strategy for managing osteoarthritis pain. Heat therapy is often more effective for chronic pain associated with osteoarthritis.
Choice B rationale
Taking aspirin on days with more pain is not recommended for osteoarthritis management. Aspirin is an NSAID and can cause gastrointestinal side effects with long-term use.
Acetaminophen is preferred for managing osteoarthritis pain due to its lower risk of side effects.
Choice C rationale
Increasing water intake to 2 liters per day is beneficial for overall health and can help maintain joint lubrication. Proper hydration is important for joint health and can help reduce the risk of further joint damage.
Choice D rationale
High-impact aerobics are not recommended for individuals with osteoarthritis as they can exacerbate joint pain and damage. Low-impact exercises such as swimming, cycling, and walking are better options for maintaining joint mobility and reducing pain.
