The correct answer is choice A. Lowering the side rail on the side of the bed where they will stand to perform mouth care.

This action by the AP requires intervention by the nurse because it increases the risk of the patient falling out of the bed or injuring themselves on the rail. The side rail should be kept up at all times unless it is necessary to lower it for a specific procedure or transfer.

Choice B is wrong because using an oral care sponge swab moistened with cool water to clean the client’s mouth is an appropriate action by the AP.

Oral care sponge swabs are designed to gently clean and moisten the oral cavity of patients who are unconscious or have difficulty swallowing. Cool water can help to soothe and refresh the mouth.

Choice C is wrong because wearing clean gloves to perform mouth care for the client is an appropriate action by the AP.

Gloves are part of standard precautions to prevent cross-contamination and protect both the patient and the caregiver from infections.

Choice D is wrong because using two gloved fingers to open the client’s mouth for cleaning is an appropriate action by the AP.

This technique can help to access the oral cavity of an unconscious patient without causing injury or discomfort. The AP should also use a bite block or a padded tongue depressor to prevent the patient from biting their fingers.
