ATI LPN Pharmacology Exam Questions
Extract:
Question 1 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.
Question 2 of 5
Calculate the following dosage using ratio and proportions method. Round answers to the nearest tenth. Order: Tegretol 200 mg p.o.t.i.d. Available
Correct Answer: B
Rationale: Assuming 100 mg tablets (implied), 200 mg / 100 mg/tab = 2 tablets.
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
Before drug reconstitution, the nurse would check the drug circular and/or drug label for instructions. After a drug has been reconstituted and additional doses are available, which information would the nurse write on the drug label? (Select all that apply.)
Correct Answer: B,C,D
Rationale: B: Specifies diluent used. C: Ensures timely use. D: Identifies preparer.
Question 5 of 5
CALCULATE FLOW RATES IN DROPS PER MINUTES: Order: Zosyn 1.3 g in 100 mL D5W IVPB 98h to infuse over 30 min. Drop factor: 60 gtt/mL. Determine rate in gtt/min.
Correct Answer: C
Rationale: Flow rate = (100 mL / 30 min) × 60 gtt/mL = 200 gtt/min.
