Final answer:
LPNs cannot teach about physical therapy exercises, demonstrate medication administration, or provide dietary education.
Step-by-step explanation:
LPNs (Licensed Practical Nurses) play a crucial role in healthcare settings, but there are certain teaching tasks they may not be able to perform. Here are some examples:
Teaching about physical therapy exercises: LPNs usually do not have the necessary specialized training to teach patients about specific physical therapy exercises.
Demonstrating medication administration: LPNs can administer medications, but they may not have the authority to demonstrate the administration process to others.
Providing dietary education: While LPNs can provide general nutritional information, they may lack the expertise to provide comprehensive dietary education.
