A 38-year-old Filipino patient, G3P2+0 presented to the
emergency department on the 18th of October 2019 complaining of
acute onset of lower abdominal pain associated with a history of
amenorrhea for three months. She was unsure of the date of her last
menstrual period and had no previous antenatal follow-up. She was
medically free, and her past obstetric history included a normal
uncomplicated vaginal delivery, followed by a cesarean section
which was performed four years back. She had no allergies and was
not taking any medication or contraception. Upon presentation, she
complained of generalized lower abdominal pain, which was of a
sudden onset, continuous, not radiating, and not relieved by oral
analgesia. The pain was associated with nausea and symptoms of
anemia such as dizziness and shortness of breath, but there was no
history of loss of consciousness, gastrointestinal or urinary tract
symptoms. There was no history of fever or symptoms suggestive of
pelvic inflammatory disease. Upon clinical examination, the patient
looked pale and distressed. Her blood pressure was 90/42 mmHg, with
a pulse rate of 110 beats per minute. Her abdomen was generally
distended and tender on both superficial and deep palpation, with
signs suggestive of peritonitis. Her hemoglobin count measured 3.2
g/L, and her total white cell count was 7.5 g/L. 1. Based on the
above scenario identify how a diagnosis would be established, what
therapy is indicated, and what preoperative nursing interventions
are appropriate. 2. Provide a complete nursing diagnosis for the
patient in this case study.
