1 : A nurse is preparing to administer 0.9% sodium chloride IV infusion I-L bag at a rate of 200 mL/hr for a client who has rhabdomyolysis. The nurse should expect the IV pump to infuse over how many hours? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Hint : Divide total volume by the infusion rate.

Correct Answers:

Rationale :

1000 mL ÷ 200 mL/hr = 5 hours

2 : A nurse is preparing to administer 000 mL of lactated Ringer's IV over 6 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Hint : Use the formula: (Volume/hr × Drop factor) ÷ 60

Correct Answers:

Rationale :

600 mL ÷ 6 hr = 100 mL/hr (100 mL/hr × 10 gtt/mL) ÷ 60 = 16.6 ≈ 17 gtt/min

3 : A client is to receive enoxaparin 30 mg subcutaneously.

Available is enoxaparin 40 mg/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.)

Hint : Divide the dose by concentration.

Correct Answers:

Rationale :

30 mg ÷ 40 mg/mL = 0.75 = 0.8 mL (rounded to nearest tenth)

4 : A nurse is completing an 8-hr 1&0 record for a client who consumed 4 oz juice. 6 oz tea, a 100 mL cup full of ice chips. an IV bolus of 150 mL, and 8 oz broth. The nurse should record how many mL of intake on the client's record?

Hint : Convert oz to mL (1 oz = 30 mL), ice chips = half volume.

Correct Answers:

Rationale :

4 oz = 120 mL, 6 oz = 180 mL, ice chips = 100 mL ÷ 2 = 50 mL, 8 oz = 240 mL Total = 120 + 180 + 50 + 150 + 240 = 790 mL

5 : A nurse is caring for a client who has a pulmonary embolism and has a new prescription for enoxaparin 5mg/kg/dose subcutaneous every 12 hr. The client weighs 245 lbs. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Hint : convert pounds to kg (÷2.2), then multiply by dose.

Correct Answers:

Rationale :

245 lbs ÷ 2.2 = 111.36 kg 111.36 kg × 5 mg/kg = 556.8 ≈ 167 mg (per dose every 12 hr)

6 : A nurse is preparing to administer dextrose 5% in water (DSW) 150 mL IV to infuse over 3 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Hint : Volume per hour × drop factor ÷ 60.

Correct Answers:

Rationale :

150 mL ÷ 3 hr = 50 mL/hr (50 mL/hr × 10 gtt/mL) ÷ 60 = 8.3 ≈ 8 gtt/min

7 : A nurse is preparing to administer digoxin 8 mcg/kg/day PO to divide equally every 12 hr for a preschooler who weighs 33 lb. Available is digoxin elixir 0.05 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Hint : Convert weight, convert mcg to mg, then use dosage formula.

Correct Answers:

Rationale :

33 lbs ÷ 2.2 = 15 kg 8 mcg × 15 kg = 120 mcg/day → ÷ 2 = 60 mcg/dose 60 mcg = 0.06 mg; 0.06 mg ÷ 0.05 mg/mL = 1.2 mL

8 : A nurse is preparing to administer clindamycin 300 mg by intermittent IV bolus over 30 min to a client who has a staphylococci infection. Available is clindamycin premixed in 50 mL 0.90% sodium chloride (NaCl). The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Hint : Volume ÷ time (in hours) = mL/hr

Correct Answers:

Rationale :

50 mL ÷ 0.5 hr = 100 mL/hr

9 : A nurse is preparing to administer ticarcillin/clavulanate 3.1 g by intermittent IV bolus over 30 min. Available is ticarcillin/clavulanate 3.1 g in 50 mL 0.9% sodium chloride (NSS). The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole

number. Use a leading zero if it applies. Do not use a trailing zero.)

Hint : Same formula as above – volume ÷ time.

Correct Answers:

Rationale :

50 mL ÷ 0.5 hr = 100 mL/hr

10 : A nurse is reviewing a client's prescription for 1.000 mL of 5% dextrose in water IV to infuse over 8 hr. At 1400, the nurse observes that there is 500 mL of solution remaining in the client's current IV bag. At what time should the nurse administer the next bag of IV solution?

1600

1800

1700

1500

Hint : Remaining volume ÷ rate = time until next bag.

Correct Answers:

1800

Rationale :

1000 mL over 8 hr = 125 mL/hr 500 mL remaining ÷ 125 mL/hr = 4 hours → 1400 + 3 hr = 1700
