Correct Answer is C
Explanation
Choice A rationale
Negligence would require proof that the nurse failed to act in a manner consistent with their training and that this failure directly caused harm to the victim. In this case, the nurse provided assistance and then left the scene after EMS arrived, which does not constitute negligence.
Choice B rationale
Assault and battery involve intentional harm or offensive contact, which is not applicable in this scenario as the nurse was providing assistance.
Choice C rationale
The Good Samaritan laws are designed to protect individuals who provide assistance at the scene of an emergency from legal liability, provided they act in good faith and within the scope of their training. In this scenario, the nurse acted to help the victim and then left the scene after EMS arrived, which is generally protected under Good Samaritan laws.
Choice D rationale
Abandonment would require that the nurse left the victim without ensuring that they were in the care of another competent individual. Since the nurse left after EMS arrived, this does not constitute abandonment.
Correct Answer is A
Explanation
Choice A rationale
Ensuring the bevel of the needle is pointing up is crucial for intradermal injections as it allows the medication to be deposited just below the epidermis, forming a small bleb or wheal.
Choice B rationale
The upper arm is not the preferred site for intradermal injections. The inner forearm and upper back are more commonly used as they allow for better visualization of the reaction.
Choice C rationale
Holding the syringe perpendicular to the skin is incorrect for intradermal injections. The correct angle is 5 to 15 degrees to ensure the medication is deposited in the dermis.
Choice D rationale
Massaging the site gently after injection is not recommended for intradermal injections as it can disperse the medication and affect the test results.
