A. Completing a follow-up focused assessment: Focused assessments require nursing judgment and clinical decision-making to identify changes in a client’s condition. This task cannot be delegated to UAP because it involves interpretation of findings and determining interventions. B. Assessing a client's mental health status: Mental health assessments require specialized knowledge and critical thinking to evaluate mood, thought processes, and risk factors. UAPs do not have the training to perform these assessments safely or interpret the results. C. Obtaining a client's vital weight: Measuring a client’s weight is a routine, noninvasive task that does not require nursing judgment. UAPs are trained to safely obtain and record vital weights, making this appropriate to delegate. D. Obtaining a client's vital signs: Vital signs are standard, routine measurements that UAPs can reliably perform. Nurses can delegate this task while retaining responsibility for interpreting the results and making clinical decisions. E. Assessing a client's medication history: Gathering medication history involves evaluating prescriptions, interactions, and adherence patterns. This requires nursing knowledge and critical thinking, so it should not be delegated to UAPs.
