Extract:
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: C
Rationale: Coffee = 8 × 29.5735 = 236.59 mL, Juice = 3 × 29.5735 = 88.72 mL, Soda = 12 × 29.5735 = 354.88 mL, Water = 800 - 200 = 600 mL, IV = 40 × 8 = 320 mL.
Total = 1600.19 mL, rounded to 1600 mL.
Question 2 of 5
Calculate the flow rate I mL/hr. and Units/hr. (Equipment used is programmable in whole mL/hr and Show all work) Order: 25,000 units of Heparin in 250 mL to infuse at 11 mL/hr. Calculate rate in units/hr.
Correct Answer: D
Rationale: Concentration = 25,000 units / 250 mL = 100 units/mL. Units/hr = 11 mL/hr × 100 units/mL = 1100 units/hr.
Question 3 of 5
A nurse is preparing to administer 0/9% sodium chloride (0.9% NaCl) 20ml/kg IV tp infuse over 6 hr to a school-age child who weighs 55 lbs. The nurse should set the IV pump to deliver how many ml/hr? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: D
Rationale: Weight = 55 lb × 0.453592 = 24.95 kg. Volume = 20 mL/kg × 24.95 kg = 499 mL. Flow rate = 499 / 6 = 83.17 mL/hr, rounded to 83 mL/hr.
Question 4 of 5
A nurse is preparing to administer phenobarbital 6 mg/kg/day PO divided in equal doses every 12 hr to a client who weighs 44 lbs. Available is phenobarbital elixir 20 mg/5ml. The nurse should administer how many mL per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use trailing zeros.
Correct Answer: B
Rationale: Weight = 44 lb × 0.453592 = 19.96 kg. Daily dose = 6 mg/kg/day × 19.96 kg = 119.76 mg. Per dose = 119.76 / 2 = 59.88 mg. Volume = 59.88 × (5 mL / 20 mg) = 14.97 mL, rounded to 15 mL.
Question 5 of 5
A patient is experiencing status epileptics. The nurse anticipates immediate administration of which drug?
Correct Answer: A
Rationale: Diazepam acts rapidly to stop seizures in status epilepticus.
