Client Profile: Mrs. Giammo is a 59-year-old woman who was brought to the emergency department by her husband. Mr. Giammo noticed that all of a sudden, his wife “was slurring her speech and her face was drooping on one side.” Mrs. Giammo told her husband that she felt some numbness on the right side of her face and in her right arm. Mr. Giammo was afraid his wife was having a stroke so he brought her to the hospital.
Case Study: In the emergency department, Mrs. Giammo is alert and oriented. Her vital signs are temperature 98.28F (36.78C), blood pressure 148/97, pulse 81, and respiratory rate 14. An electrocardiogram (ECG, EKG) monitor shows a normal sinus rhythm. Mrs. Giammo is still complaining of “numbness” of the right side of her face and down her right arm. Her mouth is noted to divert to the right side with a slight facial droop when she smiles. Her speech is clear. She is able to move all of her extremities and follow commands. Her pupils are round, equal, and reactive to light (4 mm to 2 mm) and accommodation. There is no nystagmus noted. Her right hand grasp is weaker than her left. Mrs. Giammo does not have a headache and denies any nausea, vomiting, chest pain, diaphoresis, or visual complaints. She is not experiencing any significant weakness, has a steady gait, and is able to swallow without difficulty. Laboratory blood test results are as follows: white blood cell count (WBC) 8,000 cells/mm3, hemoglobin (Hgb) 14 g/dL, hematocrit (Hct) 44%, platelets = 294,000 mm3, erythrocyte sedimentation rate (ESR) 15 mm/hr, prothrombin time (PT) 12.9 seconds, international normalized ratio (INR) 1.10, sodium (Na2+) 149 mEq/L, potassium (K+) 4.5 mEq/L, glucose 105 mg/dL, calcium (Ca2+) 9.5 mg/dL, blood urea nitrogen (BUN) 15 mg/dL, and creatinine (creat) 0.8 mg/dL. A head computed tomography (CT) scan is done which shows no acute intracranial change and a magnetic resonance imagery (MRI) is within normal limits. Mrs. Giammo is started on an intravenous heparin drip of 25,000 units in 500 cc of D5W at 18 mL per hour (900 units per hour). Mrs. Giammo is admitted for a neurology evaluation, magnetic resonance angiography (MRA) of the brain, a fasting serum cholesterol, and blood pressure monitoring. Upon admission to the nursing unit, her symptoms have resolved. There is no facial asymmetry and her complaint of numbness has subsided.
Questions 1. The neurologist’s consult report states, “At no time during the episode of numbness did the client ever develop any scotoma, amaurosis, ataxia, or diplopia.” Explain what these terms mean.
2. The neurology consult report includes the following statement: “Client’s diet is notable for moderate amounts of aspartame and no significant glutamate.” What are aspartame and glutamate? Why did the neurologist assess Mrs. Giammo’s intake of aspartame and glutamate?
3. Discuss the pathophysiology of a transient ischemic attack (TIA). Include in your discussion what causes a TIA and the natural course of a TIA.
4. Mrs. Giammo asks, “How is what I had different from a stroke?” Provide a simple explanation of how a transient ischemic attack (TIA) differs from a cerebrovascular accident (CVA, stroke).
5. Discuss the defining characteristics of a transient ischemic attack (TIA).
6. How does Mrs. Giammo’s case fit the profile of the “typical” client with a TIA?
7. Mrs. Giammo has her fasting cholesterol levels checked. How long must Mrs. Giammo fast before the test?
8. Mrs. Giammo’s cholesterol lab work reveals total cholesterol = 242 mg/dL, low-density lipoprotein (LDL) = 165 mg/dL, high-density lipoprotein (HDL) = 30 mg/dL.
Discuss the normal values of each and which of her results are of concern and why
