a student nurse assigned to a newly admitted child with acute leukemia who is receiving a blood transfusion
an RN assigned to a teenaged child diagnosed recently with bacterial meningitis
a CNA assigned to a stable male client who is 3 days post-stroke
an LPN assigned to a newly admitted child with acute leukemia who is receiving IV fluids
Number 1 is correct.
Rationale: A student nurse would not be allowed to administer a blood transfusion without supervision. The remaining assignments are within the scope of practice of each health care practitioner.
