Correct Answer is C
Explanation
Choice A rationale
Normal flora does not function as cell rebuilders. They primarily exist in a symbiotic relationship with the host without directly participating in cell repair processes.
Choice B rationale
While some normal flora aid in digestion, they are not involved in blood production. Blood production is a function of bone marrow and not influenced by normal flora.
Choice C rationale
Normal flora play a crucial role in preventing the colonization of pathogens by competing for nutrients and space, thereby protecting the body from harmful microorganisms.
Choice D rationale
Normal flora do not manage the fluid balance of the body. Fluid balance is regulated by the kidneys and the body's endocrine system, not by the normal flora.
Correct Answer is B
Explanation
Choice A rationale

Choice B rationale
Encouraging the patient to cough frequently helps clear secretions from the lungs, compensating for the diminished function of cilia in elderly patients.
Choice C rationale
Encouraging bed rest can lead to complications such as muscle atrophy, decreased lung capacity, and increased risk of pressure ulcers in elderly patients.
Choice D rationale
Restricting fluid intake to prevent pulmonary congestion is not generally recommended unless there is a specific medical condition requiring fluid restriction, as adequate hydration is vital for overall health.
