Final answer:
The nurse should report the elevated blood pressure, +2 pitting edema, headache, and heartburn to the healthcare provider as these findings may indicate postpartum hypertension or other complications requiring immediate medical attention.
Step-by-step explanation:
A nurse performing an assessment on a postpartum client should report certain findings to the healthcare provider. In this scenario, the findings that should be reported include the client's blood pressure of 152/105 mm Hg, the presence of +2 pitting edema to bilateral lower extremities, the complaint of a headache rated 3 on a scale from 0 to 10, and heartburn that began about 1 hour ago.
The other observations such as the fundus being firm and midline 2 cm below the umbilicus and the light amount of lochia rubra are normal postpartum findings within 48 hours after a cesarean delivery. However, the elevated blood pressure may indicate postpartum hypertension, the edema could suggest fluid retention or preeclampsia, and the new onset of headache and heartburn could be symptoms of a more serious condition and warrant further evaluation by a healthcare provider.
