Final answer:
The nurse would consider the bedridden client to be at risk for increased movement of secretions in the respiratory tract.
Step-by-step explanation:
The nurse would consider the bedridden client to be at risk for increased movement of secretions in the respiratory tract (option A). When a client is bedridden, they may have difficulty mobilizing and clearing secretions from their lungs, which can lead to respiratory complications such as pneumonia. This is especially true if the client is unable to cough effectively or if they have other underlying respiratory conditions.
