History of Current Problem:
Diana Humphries is a 45-year-old woman with chronic kidney disease stage III and diabetes
mellitus type1 who checks her blood sugar daily, or whenever she feels like it. She has been
feeling increasingly nauseated the past 12 hours. She has had a harsh, productive cough of
yellow sputum the past three days. She checked her blood glucose before going to bed last
night and it was 382, but then she fell asleep early and missed her bedtime dose of glargine
(Lantus) insulin. When she awoke this morning, she had generalized abdominal pain and
continued to feel nauseated and had a large emesis. Her glucometer was unable to read her
blood glucose because it was too high. She took 10 units of lispro (Humalog) insulin this
morning. Her nausea has increased all morning and she has been unable to eat or keep
anything down despite having an increased thirst and appetite. She also has had increased
frequency of urination. When her lunchtime glucometer gave no reading because it was too high
and out of range, she called 9-1-1 to be evaluated in the emergency department (ED).
Personal/Social History:
Diana has been inconsistently compliant with her medical/diabetic regimen due to her struggles
with anxiety and depression that have worsened since her mother died three months ago. She
considers 200 a good blood sugar reading. She is divorced with no children and has been
homeless and has lived in a shelter off and on the past month. She is on Social Security
disability because of complications related to diabetes. At one point during the intake interview,
she expressed to the nurse, “I’m going to die anyway, why does all this matter?”
1. What is the RELATIONSHIP between RELEVANT current problem data and the primary
medical problem?
RELEVANT Current Problem
Data:
Clinical Significance
Chronic Kidney Disease
Type 1 Diabetes and checks BG
whenever she feels like it
BG 383 before bed and didn’t
take her bedtime Lantus
Generalized abdominal pain,
nausea, emesis
Decreased function of the kidneys and if patient is in
DKA there is an increased load on kidneys due to
polyuria
Puts her at risk for developing DKA especially since she
doesn’t check her BG regularly
BG already high before bed so we know it was high for a
while before she called 911
S/S of hyperglycemiaIncreased thirst, appetite,
urination

Low BP
High due to possible lung
infection/compensation/pain
Could be due to infection and related to
the yellow sputum and productive cough
Elevated due to the decrease in blood
pressure.

cough
Could be due to beta blockers. Important
to monitor if it is out of her normal range.

to a volume depletionPain 5/10 Sharp and gets worse with coughing and

12. What is the Primary PROBLEM ?
Diabetic Ketoacidosis13. Present the Pathophysiology of the problem
Diabetic Ketoacidosis occurs in type 1 diabetics. This is when there is a
significant increase in blood glucose levels due to the lack of insulin. Glucose
accumulates in the blood result in the metabolism of ketones. Ketones will then
accumulate in the blood resulting in acidosis. The increase in acidosis will then
contribute to other complications such as shock and ultimately coma/death.
