Final answer:
The statements that demonstrate a lack of effective delegation are b), e), and f).
Step-by-step explanation:
Of the options given, the statements that demonstrate a lack of effective delegation to a LPN by the RN are:
b) The RN delegates the administration of a blood transfusion to the LPN and ensures the LPN has received the necessary training.
e) The RN delegates the administration of intravenous (IV) chemotherapy to the LPN, recognizing the LPN's competence in this area.
f) The RN delegates the interpretation of diagnostic test results to the LPN, assuming the LPN's familiarity with the relevant protocols.
In all other statements, the RN provides clear instructions, guidance, or allows the LPN to exercise independent judgment. Effective delegation involves matching the task with the skill and competence of the LPN, while still providing appropriate support and supervision.
