Answer:
C. The substance does not directly harm tissues and is not a pathogen, but nevertheless triggers an inflammatory response.
Explanation:
When a person is allergic to a substance, his or her immune system recognizes a harmless substance, such as components in food, pollen, or dust, as a treat. As a consequence, it starts an immune response that leads to inflammation. The substance that starts the allergic reaction is called an allergen, and it is not a pathogen because it is not a real threat to the body since it does not infect cells. When the allergen enters the body, it binds to antibodies that are in contact with a special type of cell. These specific cells will release a substance known as histamine. Histamine will produce an inflammatory reaction affecting different tissues in our body. For example, it can make us sneeze, have a running nose, swelling parts of our body, have itchiness and redness, amongst others.

For a nurse it is quite normal because she knows the pattern of breathing of a small baby but for a primipara ( a lady who is giving birth for the first time ) it might not be acceptable to understand the fact that a newly born baby has an irregular breathing pattern switching in between fast and slow .
As she is a new mother she might not be aware of the fact that a baby breathes very fastly to compensate the amount of energy required to maintain the homeostasis of the baby.As the baby is in growing stage the amount of energy required is much more as compared to that of adults.
Hence , the nurse will not take any medical action as the baby is not sick but yes she will definitely tell the mother that it is normal in baby
