Which action is outside LVN scope unless explicitly allowed by facility policy and competency validation?

Rationale: A. Monitor client response to IV medications is incorrect because monitoring patient response is well within the LVN scope of practice. This includes observing for therapeutic effects and adverse reactions and reporting findings to the registered nurse or provider. B. Stop an infusion for a suspected adverse reaction is incorrect because LVNs are permitted to stop an infusion if the patient is experiencing a suspected adverse reaction. This action prevents further harm and aligns with patient safety protocols. C. Hang a secondary IV medication (piggyback) as ordered is incorrect because in many states, including Texas, LVNs can hang secondary IV medications if it is per facility policy and within their training and scope. This does not usually require independent judgment beyond following the order. D. Independently administer IV push medications is correct because IV push (bolus) administration carries a high risk of rapid adverse effects. LVNs generally cannot administer IV push medications independently unless their facility has specific policies, training, and competency validation allowing it. This is considered a high-risk intervention typically reserved for RNs.
