Extract:
Question 1 of 5
A nurse is reviewing the BUN and creatinine levels of an older adult client who has chronic kidney disease. The nurse should expect which of the following findings?
Correct Answer: A
Rationale: In CKD, BUN (> 20 mg/dL) and creatinine (> 1.2 mg/dL) are significantly elevated due to reduced kidney function.
Question 2 of 5
When a client is using a cooling blanket to reduce fever, which finding indicates the need to change treatment?
Correct Answer: B
Rationale: Shivering counteracts the cooling effect of the blanket, increasing body temperature and metabolic demand. This indicates the treatment is ineffective and needs adjustment.
Question 3 of 5
Which intervention does the nurse utilize post-operatively to assess the patency of the arteriovenous fistula?
Correct Answer: B
Rationale: A functional AV fistula should have a palpable thrill (vibration) and an audible bruit (whooshing sound) when auscultated with a stethoscope. These findings confirm adequate blood flow and patency.
Question 4 of 5
