Using the label, what is the trade name of the medication? (No label provided; assuming Zestril from prior context.)

Choice A reason: Informing the patient is secondary; it addresses communication but not immediate safety risks like needlestick injury, which is a higher priority post-injection per occupational health standards.

Choice B reason: Assessing comfort is important but not urgent; pain evaluation can wait after securing the needle, as safety from sharps exposure outweighs immediate patient feedback in priority.

Choice C reason: Engaging the safety sheath prevents needlestick injuries; it’s the priority action to protect the nurse and others from bloodborne pathogens, aligning with universal precautions post-injection.

Choice D reason: Checking for bleeding is routine but not critical; minor oozing is common and manageable later, while needle safety is an immediate concern to prevent infection risks.

Choice A reason: A 12-degree angle is too shallow, increasing the risk of incorrect placement and ineffective administration of the intradermal injection.

Choice B reason: The 15-degree angle ensures precise intradermal placement, forming a wheal that indicates proper administration into the dermis for optimal absorption.

Choice C reason: A 30-degree angle places the medication too deep into subcutaneous tissue, compromising intended drug absorption.

Choice D reason: A 45-degree angle results in subcutaneous rather than intradermal injection, altering the drug’s effectiveness and purpose.
