NCLEX PN Practice Tests Practice Question
The nurse is to administer a tuberculin skin test. At what angle should the needle be inserted?
Correct Answer: A
Rationale: In administering a tuberculin skin test, the needle should be inserted at a 10-degree angle to ensure the medication is placed just beneath the skin's surface, allowing for accurate reading of the test results.
Option B (30-degree angle) is too steep, potentially causing the medication to enter the subcutaneous tissue rather than the intradermal layer. Option C (60-degree angle) is inappropriate for intradermal injections, as it increases the risk of deeper penetration. Option D (90-degree angle) is used for intramuscular injections, not for the tuberculin test, which requires a much shallower angle.
