Final answer:
When giving a bed bath, the nurse should start with the patient's face to maintain hygiene by cleaning the cleanest parts first before proceeding to other areas.
Step-by-step explanation:
When giving a bed bath, it is generally recommended to start with the cleanest areas of the body to avoid transferring dirt or bacteria to cleaner areas. Therefore, the nurse should begin with the patient's face. After the face, other parts of the body can be washed in descending order of cleanliness. So, for the question, 'When giving a bed bath, on which body part should the nurse begin to work?', the answer is:
c) Face
It's important to use gentle motions and to warm the washcloth to ensure the patient's comfort. A systematic approach helps ensure all areas are properly cleaned and provides a sense of structure both for the nurse and the patient.
