Pt movement is a big contributor to which complication during injections?

• A. Hematoma
• B. Infection
• C. Nerve injury
• D. Needle breakage

Answer: (D)

Movement during injections creates torque and bending in the needle. A long, thin needle is especially prone to bending or snapping if the patient shifts suddenly, leaving a fragment that could break off and require retrieval. This mechanical failure from a momentary jerk or deflection is the complication most directly linked to patient movement. The other issues—hematoma from puncturing a vessel, infection from contamination, and nerve injury from close proximity or intraneural contact—arise more from anatomy, sterility, and precise needle placement than from the patient moving during the injection. To limit risk, stabilize the needle, keep the patient comfortable, and avoid forcing or bending the needle; if a breakage occurs, follow proper retrieval and management protocols.
