With this question, I think they want you to recognize that the patient isn't having chest pain related to the heart. They emphasize several rib fractures and a pneumothorax but don't indicate any heart damage (lack of adventitious sounds = no pulmonary edema indicated or a lung issue related to heart problem).
The pericarditis is what's innervated by the phrenic n. Seeing as how his heart is fine, the fractured ribs are probably what are causing him pain via the intercostal nerves.
why? like does my med school suck or am I just that dumb cuz we never learned anything like this
The idea to know its a somatic pain so in other choices only its could be phrenic or intercostal Phrenic usually will mentioned radiating to shoulder in adition what mentioned above about phernic nerve innervation for parietal pleural

Costal and cervical pleura is innervated by inercostal nerve, mediastinal and diaphragmatic pleura is innervated by phrenic nerve.Intercostal nerva pain typically felt closer to the pain, phrenic nerve (C3-5) pain is radiated pain by SUPRACLAVICULAR nerve area (shoulder). Uw question ID: 1535

Pain fibers for Parietal pleura: Cervical and Costal parts is by Intercostal Nerve, Diaphragmatic and Mediastinal via Phrenic Nerve. Rib cage injury causes costal pleural pain.
