A nurse is caring for a client who has a deep vein thrombosis and is prescribed heparin by continuous IV infusion at 1,200 units/hr. Heparin is available in a concentration of 25,000 units in 500 mL D5W. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 24
Rationale: Calculation: (1,200 units/hr ÷ 25,000 units) × 500 mL = 24 mL/hr

A nurse is reviewing the arterial blood gas (ABG) values of a client who has chronic kidney disease. Which of the following sets of values should the nurse expect?
- A. pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg
- B. pH 7.50, HCO3- 20 mEq/L, PaCO2 32 mm Hg
- C. pH 7.55, HCO3- 30 mEq/L, PaCO2 31 mm Hg
- D. pH 7.30, HCO3- 26 mEq/L, PaCO2 50 mm Hg

A nurse is preparing to administer digoxin at a dosage of 8 mcg/kg/day orally, divided equally every 12 hours, to a preschooler who weighs 33 lbs. Digoxin elixir is available at a concentration of 0.05 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 1.2
Rationale: Calculation: 33 lbs ÷ 2.2 = 15 kg; 15 kg × 8 mcg/kg/day = 120 mcg/day; 120 mcg ÷ 2 = 60 mcg/dose; 60 mcg = 0.06 mg; 0.06 mg ÷ 0.05 mg/mL = 1.2 mL
