Case Study (Add-On Clinical Case Study)

Simon Cowell Patient.

History of Present Illness:

Simon Chamberlain is a 49 year-old Caucasian male client who had been in good health until about two months ago when he started to feel weak and tired more rapidly than usual. Upon questioning him, he admitted to getting up two or three times a night to urinate. He also is often thirsty at those times and drinks a glass of water each time.

Simon's weight had been average throughout high school, where he had been on the football team. After leaving school, he had gradually gained weight over the years. His appetite remained excellent but he has noticed he is now losing weight and becoming weak.

The pain in his feet was worse at night and sometimes kept him awake. It was burning in character and sometimes his toes felt numb. The tingling and numbness in his fingers was causing him problems at his work as an auto mechanic because he frequently drops small parts or has difficulty making fine manualadjustments to engines.His vision was blurry at times, especially in the afternoon. All other symptoms were negative.

Simon was primarily responsible for his mother's care during her later years. He administered her insulin shots twice a day and transported her to and from the dialysis center.

Hospitalization Course:

Simon came in for another doctor's visit with complaints of feeling extremely weak and tired. He also presents with a swollen left leg that is very painful. Upon examination, the nurse noted heat and tenderness to the left lower extremity with 2+ pitting edema. Simon admits to having stubbed his toe three or four days ago but didn't think it was of any concern. When the physician checked his random blood sugar, it was 352 mg/dL. The physician then admitted him to the hospital in the medical surgical floor with the following admitting orders:

Order rationale

Diet 2000cal ADA dietto control blood glucose and lose Wight

Activity: BRP

IV Fluids: 1L NS at 75 mL/hr

e. At what time would Simon be at most risk for this adverse reaction?

The next morning, the MD changed Simon's insulin sliding scale order to Insulin lispro.

f. If Simon's BS at 0700 is 208 mg/dL. How much insulin will you administer based on the sliding scale order (Use same sliding scale for Regular insulin and change Regular insulin to Insulin lispro)

g. If breakfast tray comes at 0800, what time will you administer the insulin?

h. At what time would Simon be at risk for s/s/ or hypoglycemia after administration of Insulin Lispro?

5. Discuss the acute and chronic complications of Diabetes Mellitus

Acute Complications: Differentiate Diabetic Ketoacidosis and Hyperosmolar Hyperglycemic Nonketotic Syndrome

6. Describe the pathophysiology that leads to the long-term (chronic) complications of diabetes Macrovascular

- Cardiovascular

- Cerebrovascular

- Peripheral Vascular

Microvascular

- Retinopathy

Sudden vision loss, rupture retina blood vessels,

- Nephropathy

Disease because the kidney's filtration mechanism is stressed and thickening in glomerulus

- Neuropathy

Affects the distal portions of the nerves, especially the nerves of the lower extremities (peripheral neuropathy)

7. Diabetes management: BS control through Diet, Exercise, and Medications

a. What is the frequency for monitoring blood sugar levels?

b. How often should Simon monitor his blood sugar and how often you he be seen by his physician?

c. What is Simon's target FBS range and HgbA1C range?

8. Simon wrote down what he usually eats for dinner.

3 oz lean steak or 2 oz chicken
1 cup milk
1 cup steamed broccoli
1 cup winter squash
3 oz baked potato
1 bowl (2 cups) of ice cream (28 g of CHO per serving)
1 can regular soda (45 g of CHO per serving/can)
