Extract:
Question 1 of 5
Order: 1 liter or 1000 mL of D5W to infuse over 6 hours Available: Macrodrip set: 10 gtt/mL The IV flow rate would be ______gtt/min.
Correct Answer: A
Rationale: Flow rate = (1000 mL / 6 hr × 10 gtt/mL) / 60 = 27.78 gtt/min, rounded to 28 gtt/min.
Question 2 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 3 of 5
Low molecular weight heparin (LMWH) is used for what type of patient?
Correct Answer: D
Rationale: LMWH prevents clots, commonly used for DVT.
Question 4 of 5
A nurse is preparing to administer acetaminophen 10/mg/kg PO to a preschool child for fever. The child weighs 22 lb . Available is acetaminophen liquid 160mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: C
Rationale: Weight = 22 lb × 0.453592 = 9.98 kg. Dose = 10 mg/kg × 9.98 kg = 99.8 mg. Volume = 99.8 mg × (5 mL / 160 mg) = 3.12 mL, rounded to 3.1 mL.
Question 5 of 5
Which one is not a step of pharmacokinetics?
Correct Answer: D
Rationale: Synthesis is drug creation, not a pharmacokinetic process like absorption, distribution, or metabolism.
