NCLEX CRUSADE ACADEMY TEST - 5 DOSAGE CALCULATION PRACTICE CLASS

1. According to NCLEX rounding rules, when rounding to the nearest tenth, what should be done if the next digit is 5 or greater?. Keep the number the same. Round down. Round up. Convert to fraction.

2. When rounding 4.56 to the nearest tenth, what is the correct answer?. 4.5. 4.6. 5.0. 4.55.

3. When rounding 4.34 to the nearest tenth, what is the correct answer?. 4.4. 4.3. 4.5. 4.0.

4. What is the primary purpose of dimensional analysis in medication calculations?. Memorizing formulas. Cancelling units to reach the desired unit. Increasing medication dosage. Avoiding conversions.

5. In dimensional analysis, what is meant by a 'marriage'?. A conversion that cannot be separated. A patient safety check. A medication dose. A nursing procedure.

6. Which step in the clinical math engine involves identifying all given data in the problem?. Anchor. Extract. Cancel. Execute.

7. What does the 'Anchor' step in clinical math refer to?. Cancelling units. Starting the equation with the requested unit. Multiplying numbers. Estimating the answer.

8. A patient receives 1000 mL normal saline over 12 hours with a drop factor of 15 gtt/mL. What is the drip rate?. 18 gtt/min. 21 gtt/min. 30 gtt/min. 15 gtt/min.

9. A heparin infusion is ordered at 1300 units/hr. The bag contains 20,000 units in 250 mL. What rate should the pump be set to?. 10 mL/hr. 16 mL/hr. 20 mL/hr. 25 mL/hr.

10. A medication order is 10 mg/kg/dose. The patient weighs 55 lbs. What is the correct dose?. 100 mg. 250 mg. 550 mg. 125 mg.

11. What is the correct conversion factor for pounds to kilograms?. 1 kg = 1 lb. 1 kg = 2.2 lb. 1 lb = 3 kg. 1 kg = 0.5 lb.

12. Which data should be ignored when calculating intake if only intake is requested?. IV fluids. Oral fluids. Urinary output. Tube feeding.

13. How many mL are in 1 ounce of fluid?. 10 mL. 15 mL. 20 mL. 30 mL.

14. According to the diaper rule, how much urine equals 1 gram of diaper weight?. 0.5 mL. 1 mL. 2 mL. 5 mL.

15. What formula is used to calculate diaper output?. Wet Dry = Output. Wet Dry. Dry Wet. Wet + Dry.

16. A dry diaper weighs 30 g and a wet diaper weighs 50 g. What is the urine output?. 10 mL. 15 mL. 20 mL. 30 mL.

17. What is the purpose of cancelling units in dimensional analysis?. To simplify fractions. To reach the target unit. To estimate answers. To avoid conversions.

18. If an IV bag of 1000 mL infuses at 240 mL/hr, how much fluid is infused in 3.5 hours?. 600 mL. 720 mL. 840 mL. 900 mL.

19. If 840 mL has infused from a 1000 mL bag, how much remains?. 160 mL. 200 mL. 140 mL. 100 mL.

20. In clinical judgment, why might weighing diapers be preferred over catheterization for infants?. It is faster. It is cheaper. It reduces infection risk. It produces larger numbers.

21. Which unit conversion is correct?. 1 hr = 100 min. 1 hr = 60 min. 1 hr = 30 min. 1 hr = 90 min.

22. What is the final step of the clinical math engine?. Extract. Anchor. Execute. Cancel.

23. Why must rounding instructions be followed carefully in NCLEX calculations?. They change medication names. Incorrect rounding makes the answer wrong. It changes patient diagnosis. It eliminates conversions.

24. What should always remain at the end of dimensional analysis?. The original unit. Multiple units. The target unit. No units.

25. Which strategy improves safety when solving dosage problems?. Skipping conversions. Estimating quickly. Carefully reading the question target unit. Ignoring distractors.
