NCLEX-RN Exam Practice Questions
Extract:
Question 1 of 5
When assessing the client's blood pressure, the nurse should use a cuff with a width that is __% of the circumference of the extremity. (Fill in the blank.)
Correct Answer: 40
Rationale: The blood pressure cuff width should be approximately 40% of the extremity’s circumference to ensure accurate readings. A cuff too narrow or wide can falsely elevate or lower readings.
Question 2 of 5
The client is receiving a continuous infusion of insulin for diabetic ketoacidosis. Which laboratory value should the nurse monitor most closely?
Correct Answer: A
Rationale: Insulin therapy in diabetic ketoacidosis shifts potassium into cells, risking hypokalemia, which can cause arrhythmias. Sodium, BUN, and A1C are monitored but are less critical during acute treatment.
Question 3 of 5
A client has been diagnosed with congestive heart failure. His fluid intake and output are strictly regulated. For lunch, he drank 8 oz of milk, 4 oz of tea, and 6 oz of coffee. His intake would be recorded as:
Correct Answer: B
Rationale: 1 oz = 30 mL; therefore, 18 oz = 540 mL.
Question 4 of 5

D) are correct.
Question 5 of 5
A client with a history of a kidney transplant is receiving Prednisone. The nurse should monitor the client for:
