Question 1 of 5
A nurse is calculating a client's fluid intake over the past 8 hr. The client had one 8-oz cup of coffee 3 oz of juice, and 12 oz of soda. The client's water pitcher had 800 mL and 200 mL remain. The client also had IV fluids infusing at 40 mL/hr via an IV pump. How many mL should the nurse document as the client's total intake for the shift?
Correct Answer: A
Rationale: Coffee: 8 oz × 30 mL/oz = 240 mL, Juice: 3 oz × 30 mL/oz = 90 mL, Soda: 12 oz × 30 mL/oz = 360 mL, Water consumed: 800 mL - 200 mL = 600 mL, IV fluids: 40 mL/hr × 8 hr = 320 mL,
Total intake = 240 mL + 90 mL + 360 mL + 600 mL + 320 mL = 1,610 mL.
Question 2 of 5
A nurse is caring for a client who has a new prescription for warfarin. The nurse should use the results of which of the following diagnostic tests to monitor the effect of this therapy?
Correct Answer: C

Question 3 of 5
A nurse is calculating a client's fluid intake over the past 8 hr. The client had one 8-oz cup of coffee 3 oz of juice, and 12 oz of soda. The client's water pitcher had 800 mL and 200 mL remain. The client also had IV fluids infusing at 40 mL/hr via an IV pump. How many mL should the nurse document as the client's total intake for the shift?
Correct Answer: A
Rationale: Coffee: 8 oz × 30 mL/oz = 240 mL, Juice: 3 oz × 30 mL/oz = 90 mL, Soda: 12 oz × 30 mL/oz = 360 mL, Water consumed: 800 mL - 200 mL = 600 mL, IV fluids: 40 mL/hr × 8 hr = 320 mL,
Total intake = 240 mL + 90 mL + 360 mL + 600 mL + 320 mL = 1,610 mL.
Question 4 of 5
A nurse is assisting in preparing an in-service program about preventing medication errors when transcribing a prescription. The nurse is using a dosage example of two tenths of a milligram. Which of the following transcription examples should the nurse use?
