Final answer:
The charge nurse should not delegate the task of removing a urinary catheter to the nursing assistant.
Step-by-step explanation:
The charge nurse should not delegate the task of removing a urinary catheter to the nursing assistant. Removing a urinary catheter requires specialized knowledge and skills that only a registered nurse or healthcare professional should perform. The nursing assistant can perform tasks such as changing soiled linen and taking a blood pressure on someone receiving blood, under the supervision of the charge nurse. However, assessing a patient's lung sounds should be performed by a registered nurse, as it requires critical thinking and clinical judgment.
