Question 1 of 5
The nurse has orders for dopamine at 20 mcg/kg/min. The bag has 500 mg of dopamine in 500 mL. The client weighs 60 kg. What rate will the nurse set?
Correct Answer: 72 mL/hr
Rationale: Dose: 20 mcg/kg/min × 60 kg = 1200 mcg/min. Concentration: 500 mg/500 mL = 1 mg/mL = 1000 mcg/mL. Rate: 1200 mcg/min ÷ 1000 mcg/mL = 1.2 mL/min × 60 min/hr = 72 mL/hr.
Question 2 of 5
A client was to receive 1 g of vancomycin intravenously in 200 mL of iso-osmotic solution over 60 minutes per infusion pump. However, the IV administration was discontinued after 45 minutes because the client developed nausea and chills. How many milligrams of vancomycin did the client receive? Record your answer using a whole number.
Correct Answer: 750
Rationale: 1 g = 1000 mg in 200 mL over 60 min. In 45 min, 45/60 = 0.75 of dose = 0.75 X 1000 = 750 mg.

The nurse is caring for a client hospitalized with bipolar disorder, manic phase who is taking lithium. Which of the following snacks would be best for the client with mania?
