A patient has been prescribed to receive 0.3 mL of U-500 insulin. Which syringe will the nurse use to administer the medication?
3-mL syringe
U-100 syringe
Needleless syringe
Tuberculin syringe
The Correct Answer is D
A. A 3-mL syringe is not appropriate for administering U-500 insulin, as the concentration may not allow for accurate dosing at such a small volume.
B. A U-100 syringe is designed for U-100 insulin and would not provide accurate measurement for U-500 insulin.
C. A needleless syringe may be useful in certain contexts, but it does not specifically provide the necessary precision for insulin dosage.
D. A tuberculin syringe is suitable for administering small doses (like 0.3 mL) and provides more accurate measurement for high-concentration insulin such as U-500.

Correct Answer is A
Explanation
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","C","D","E"]
Explanation
A. Communication signs for airborne precautions are necessary to inform staff and visitors about the required precautions for TB, which is spread via airborne transmission.
B. A surgical mask is not adequate for TB; instead, an N95 respirator is required to filter out the airborne particles effectively.
C. The N95 respirator, gown, gloves, and eyewear are essential personal protective equipment for caring for a patient with tuberculosis. The N95 respirator specifically protects against inhaling infectious particles.
D. Negative-pressure airflow in the room is critical for tuberculosis patients to prevent airborne contaminants from spreading to other areas of the facility.
E. A private room is required to isolate the patient and reduce the risk of transmission to other patients and staff.
F. A communication sign for droplet precautions is not applicable as tuberculosis is primarily transmitted via airborne routes, not droplet transmission.
