QUESTION 1
A client with chronic kidney disease (CKD) is scheduled for hemodialysis.
Which laboratory value should the nurse report to the provider immediately
prior to the procedure?
A. Serum potassium 5.2 mEq/L
B. Serum potassium 6.8 mEq/L
C. BUN 45 mg/dL
D. Serum creatinine 3.5 mg/dL
Correct Answer: B. Serum potassium 6.8 mEq/L
*Rationale: * A serum potassium level of 6.8 mEq/L is dangerously high
and can cause life-threatening cardiac arrhythmias. This requires immediate
intervention, possibly including emergency hemodialysis. The provider must
be notified immediately. A potassium of 5.2 is elevated but less emergent.
BUN and creatinine elevations are expected in CKD but are not immediately
life-threatening.
,QUESTION 2
The nurse is caring for a client with diabetic ketoacidosis (DKA) who is
receiving an insulin infusion. Which laboratory value requires the most
frequent monitoring?
A. Blood glucose
B. Serum potassium
C. Serum sodium
D. Serum calcium
Correct Answer: B. Serum potassium
*Rationale: * During DKA treatment, insulin drives potassium into cells,
which can cause severe hypokalemia. This can lead to cardiac arrhythmias
and respiratory muscle weakness. Potassium levels must be monitored
frequently (every 1-2 hours) during insulin therapy. Blood glucose is also
important but potassium is the most critical for safety.
QUESTION 3
A client with hyperthyroidism is prescribed propylthiouracil (PTU). The nurse
should instruct the client to report which adverse effect immediately?
, A. Weight gain
B. Sore throat and fever
C. Bradycardia
D. Drowsiness
Correct Answer: B. Sore throat and fever
*Rationale: * PTU can cause agranulocytosis, a severe drop in white blood
cells that increases infection risk. Sore throat and fever are early signs of
agranulocytosis and should be reported immediately. Weight gain,
bradycardia, and drowsiness are not typical adverse effects of PTU.
QUESTION 4
The nurse is caring for a client with acute renal failure who is in the oliguric
phase. Which assessment finding is expected?
A. Urine output of 1,500 mL/day
B. Urine output of 200
1-50
