The nurse is planning to administer a tuberculin test with a 27-gauge, 5/8-inch needle. At which angle will the nurse insert the needle?
15 degree
90 degree
30 degree
45 degree
The Correct Answer is A
A. The tuberculin test is administered intradermally, and the needle should be inserted at a 15-degree angle to ensure the medication is delivered just under the surface of the skin.
B. A 90-degree angle is used for intramuscular injections, not for intradermal tests like the tuberculin test.
C. A 30-degree angle is commonly used for subcutaneous injections and is too deep for an intradermal injection.
D. A 45-degree angle is also used for subcutaneous injections but is not suitable for intradermal injections.

Correct Answer is A
Explanation
A. After a nurse is exposed to blood from a cut by a used scalpel, it is crucial to test the patient for bloodborne pathogens (e.g., HIV, hepatitis B, hepatitis C) and to offer post-exposure prophylaxis or treatment to the nurse if indicated.
B. While removing gloves and disposing of them properly is part of standard infection control practices, it is not the primary process required after an exposure incident.
C. Although the nurse should report the incident, providing a medical evaluation should follow the protocols established by the facility, not just the manager's assessment.
D. Properly disposing of the scalpel in a sharps container is necessary for safety but does not directly address the required process for managing exposure to blood.
Correct Answer is C
Explanation
