Question

A nurse is preparing to administer amoxicillin 320 mg PO every 12 hr to an infant. The amount available is amoxicillin suspension 400 mg/5 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.)

Answer 1

Correct Answers:

4

Rationale :

🌟 Ordered dose = 320 mg

🌟 Available dose = 400 mg per 5 mL

🌟 Set up: 320 mg ÷ 400 mg × 5 mL

🌟 320 ÷ 400 = 0.8

🌟 0.8 × 5 mL = 4 mL

✅ Answer: 4 mL

Answer 2

Correct Answers:

50

Rationale :

🔷 Formula: mL/hr × drop factor ÷ 60 min

🔷 Set up: 150 mL/hr × 20 gtt/mL ÷ 60 min

🔷 150 × 20 = 3000

🔷 3000 ÷ 60 = 50 gtt/min

🔷 The 12 hr tells the infusion duration, but the flow rate is based on mL/hr.

✅ Answer: 50 gtt/min

Answer 3

Correct Answers:

0.8

Rationale :

💎 Ordered dose = 30 mg

💎 Available dose = 40 mg per 1 mL

💎 Set up: 30 mg ÷ 40 mg × 1 mL

💎 30 ÷ 40 = 0.75 mL

💎 Round to nearest tenth: 0.8 mL

✅ Answer: 0.8 mL

Answer 4

Correct Answers:

0.5

Rationale :

✨ Ordered dose = 125 mcg

✨ Convert available dose to mcg: 0.25 mg × 1000 = 250 mcg

✨ Available dose = 250 mcg per tablet

✨ Set up: 125 mcg ÷ 250 mcg × 1 tablet

✨ 125 ÷ 250 = 0.5 tablet

✅ Answer: 0.5 tablet

Answer 5

Correct Answers:

100

Rationale :

🔶 Formula: mL/hr × drop factor ÷ 60 min

🔶 Set up: 100 mL/hr × 60 gtt/mL ÷ 60 min

🔶 100 × 60 = 6000

🔶 6000 ÷ 60 = 100 gtt/min

🔶 Because the tubing is 60 gtt/mL, the gtt/min equals the mL/hr.

✅ Answer: 100 gtt/min

Answer 6

Correct Answers:

8

Rationale :

🌟 Step 1: Convert hours to minutes

🌟 3 hr × 60 min = 180 min

🌟 Step 2: Use IV flow rate formula

🌟 Formula = Total mL × Drop factor ÷ Time in minutes

🌟 Set up:

🌟 150 mL × 10 gtt/mL ÷ 180 min

🌟 150 × 10 = 1500

🌟 1500 ÷ 180 = 8.3

🌟 Round to nearest whole number = 8 gtt/min

✅ Answer: 8 gtt/min

Answer 7

Correct Answers:

0.8

Rationale :

🔷 Ordered dose = 100 mg

🔷 Available dose = 250 mg per 2 mL

🔷 Set up:

🔷 100 mg ÷ 250 mg × 2 mL

🔷 100 ÷ 250 = 0.4

🔷 0.4 × 2 mL = 0.8 mL

✅ Answer: 0.8 mL

Answer 8

Correct Answers:

1

Rationale :

💎 Ordered dose = 12.5 mg

💎 Available dose = 12.5 mg per 5 mL

💎 Set up:

💎 12.5 mg ÷ 12.5 mg × 5 mL

💎 12.5 ÷ 12.5 = 1

💎 1 × 5 mL = 5 mL

💎 Convert mL to tsp:

💎 5 mL ÷ 5 = 1 tsp

✅ Answer: 1 tsp

Answer 9

Correct Answers:

84.1

Rationale :

Enoxaparin 1 mg/kg/dose

Client weight = 185 lb

✨ Step 1: Convert pounds to kilograms

✨ 185 lb ÷ 2.2 = 84.1 kg

✨ Step 2: Calculate dosage

✨ 1 mg × 84.1 kg = 84.1 mg

✅ Answer: 84.1 mg per dose

Answer 10

Correct Answers:

2

Rationale :

Amoxicillin 2 g/day PO divided into 2 doses

Available = 500 mg tablets

🔶 Step 1: Convert grams to milligrams

🔶 2 g × 1000 = 2000 mg/day

🔶 Step 2: Divide into 2 doses

🔶 2000 mg ÷ 2 = 1000 mg per dose

🔶 Step 3: Calculate tablets

🔶 1000 mg ÷ 500 mg = 2 tablets

✅ Answer: 2 tablets per dose
