PATHOPHYSIOLOGY
CASE STUDY QUESTIONS:1.) T.A has questions about his surgery. He asks you, “I was fine before surgery. I’d still be fine now if I hadn’t been operated on, wouldn’t I? Based on your knowledge of AAA, what will your response be?
2. Why are you so concerned about the weakness in T.A’s legs?
3. You are performing your initial assessment of T.A’s legs. What findings should you record?
4. Four hours after admission to your floor, you noted that T.A has had a urinary output of 75 ml of dark amber urine. Why are you so concerned?
5. You need to examine the catheter and tubing for obstructions and there are none. What other assessments do you need to gather?
CASE STUDY PROGRESSES… You notify the physician of the decrease
in urine output. The physician orders STAT electrolyte panel and asks you to call him with the results. SERUM TEST RESULTS NORMAL RANGE
Potassium 5.3 mEq/L
Sodium 132 mEq/L
BUN 48 mg/dL
Creatinine 2.4 mg/dL
INTERPRETATION OF LAB RESULTS
CASE STUDY PROGRESSES… The physician determines that T.A is in
the beginning phases of acute renal failure. T.A is sent to radiology for placement of dialysis catheter. Upon T.A’s return, the physician updates T.A’s medical orders.
7. Indicate the expected outcome for T.A that is associated with each of the following medications he is receiving.
MEDICATIONS Lantus (Insulin glargine) 30 units subcu daily NovoLog (Insulin aspart) subcu per sliding scale

8. The dialysis catheter is inserted into T.A’s left subclavian vein. You are preparing to administer the IV antibiotic and find that his only other IV access, a peripheral line, is the site of the dopamine infusion., What will you do?
9. T.A is placed on fluid restriction and a renal diet. T.A asks what he is going to be able to eat and drink on this diet. What is your reply?
10. As you plan care of T.A for the remainder of the shift, identify which aspect of his care you can delegate to the assistive personnel (NAP). Select all that apply.
