Correct Answer: B
Rationale: When a client is suffering from respiratory difficulty and requires suctioning, the appropriate method to use is a portable or wall suction machine with tubing and collection receptacle. This method is necessary to effectively remove excess secretions or fluids from the airway and improve the client's breathing. Goggles are not needed in this situation as they are not directly related to the suctioning procedure. Dextrose-and-water solution and nasal cannula are also not appropriate methods for suctioning and would not effectively address the respiratory difficulty.
