Extract:
Question 1 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 2 of 5
A nurse is preparing to administer 0.9% sodium chloride (NS) 100 mL/V to infuse over 4 hr. The drip factor of the manual IV tubing is 60 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number.)
Correct Answer: B
Rationale: Flow rate = (100 mL / 4 hr × 60 gtt/mL) / 60 = 25 gtt/min.
Question 3 of 5
Which drug group inhibits the formation of clots?
Correct Answer: D
Rationale: Anticoagulants prevent clot formation.
Question 4 of 5
Convert the following metric measures to kg by moving the decimal: 5,524 g
Correct Answer: A
Rationale: 5,524 g ÷ 1000 = 5.524 kg.
Question 5 of 5
A physician ordered 1/4 strength Isomil 12 oz via nasogastric tube over 6 hours. How much solvent (water) will be needed?
Correct Answer: B
Rationale:
Total volume = 12 oz × 29.5735 = 354.88 mL. Isomil = 354.88 × 1/4 = 88.72 mL. Water = 354.88 - 88.72 = 266.16 mL, rounded to 270 mL.
