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 A
Explanation
Choice A rationale
Abduction is the correct position for the client’s right leg following a right total hip arthroplasty. This position helps prevent dislocation of the hip joint by keeping the leg away from the midline.
Choice B rationale
Internal rotation should be avoided as it can increase the risk of hip dislocation. This position places stress on the new hip joint.
Choice C rationale
External rotation is also not recommended as it can lead to dislocation of the hip joint. Proper alignment is crucial for healing.
Choice D rationale
Adduction, or moving the leg towards the midline, should be avoided as it significantly increases the risk of hip dislocation. Keeping the leg in abduction helps maintain joint stability.
Correct Answer is C
Explanation
Choice A rationale
Consuming alcohol before bed can worsen GERD symptoms by relaxing the lower esophageal sphincter and increasing acid reflux.
Choice B rationale
Eating a snack before bed can increase the likelihood of acid reflux during sleep, as lying down shortly after eating can promote reflux.
Choice C rationale
Elevating the head of the bed helps reduce acid reflux by keeping stomach acid from flowing back into the esophagus during sleep.
Choice D rationale
Sleeping on the stomach with the head flat can exacerbate GERD symptoms by increasing pressure on the stomach and promoting acid reflux.
