Final answer:
The statement that a registered nurse performs patient assessments, creates care plans, and evaluates treatment effectiveness is true. Registered nurses have a wide range of responsibilities including providing dialysis treatments under direct supervision and collaborating with medical teams on patient care.
Step-by-step explanation:
The statement is true: A registered nurse's responsibilities indeed involve performing patient assessments, creating care plans, and evaluating the appropriateness of treatment and effectiveness of care. Registered nurses work under direct supervision and have a broad scope of duties. For example, in a dialysis setting, a registered nurse may focus on providing dialysis treatments, which includes taking and reporting a patient's vital signs, preparing solutions and equipment, and ensuring procedures are accurate and sterile. Furthermore, the multidisciplinary team, including the surgeon, nurse, and anesthesia professional, may collaborate to review the recovery and care plan for a patient, reinforcing the critical role nurses play in patient care and treatment evaluation.
