Answer:

115 mcg : 50 mL = x : 1 mL = 50 X = 115 = 2.3 mcg/mL Question 2: A medication bottle reads: 1.5 g per 60 mL vial. The concentration of this medication is _______ mg/mL.

Answer:

1.5 g : 60 mL = x g : 1 mL = 60x/60 =1.5 /60 = 0.025g = 1 g = 1,000 mg /1 g = x mg/0.025 g = 25 mg/mL or 1 000 mg/1g = x mg/0.025g =25 mg/mL Question 3: The patient with myxedema is ordered levothyroxine (Synthroid) 75 mcg in 250 mL of D2.5W stat. The concentration for this medication is ______ mcg/mL.

Answer:

75 mcg /250 mL = 0.3 mcg/mL

Question 4: The patient is to receive 2 grams lidocaine in 1,000 mL of NS. The concentration of this medication is __ mg/mL.

Answer:

• g : 1,0000 mL = x :1 mL = 1,000x =2 = 0.002 g = 1,000 ,g/1 g = x mg / 0.002 g =2 mg/mL

Question 5: The patient is ordered 8 units per hour of insulin. The medication arrives from the pharmacy as 600 units in 250 mL ½ normal saline (NS). The infusion rate for this medication is ____ mL/hr (to the nearest tenth).

Answer:

600 units : 250 mL = 8 units : x mL = 250 mL x 8 units = 600 x / 600 =2000/600 =3.3 mL/hr Question 6: The pediatric patient is ordered 1,000 units per hour of heparin. The medication arrives from the pharmacy as 5,000 units in 100 mL ¼ NS. This medication should be infused at __ mL/hr.

Answer:

5,000 units : 100 mL = 1,000 units : x mL = 100 x 1, 0000 = 5,000 x X = 100,000 /5,000 = 20 mL/hr Question 7: The healthcare provider orders 1,500 units per hour of heparin. The medication arrives from the pharmacy as 25,000 units in 500 mL D5W. Therefore, this medication should be infused at __ mL/hr.

Answer:

25,000 units : 500 mL = 1,500 units : x mL = 1, 500 units x 500 mL = 25,000 x X = 25,000 = 25000 x X = 750,000/25,000 = 30mL/hr Question 8: Regular insulin is labeled 1,000 units/10 mL. The concentration of this medication is ______ units/mL.

Answer:

1,000 units /10 mL = 100 units/ mL Question 9: The patient is to receive azithromycin (Zithromax) 1 g in 500 mL. The concentration of this medication is __ mg/mL.

Answer:

• g : 500 mL = x g : 1mL = 500x = 1 = 0.02g = convert 1,000 / 1g= 2 mg/mL

Question 10: Dopamine 1 mcg/min is ordered for the patient and arrives from the pharmacy in a 400 mg in 250 mL bag of NS. The concentration of the medication is __ mcg/mL.

Answer:

400 mg x 1,000 mcg = 250 mL x 1 mg = 1,600 mcg/mL Question 11: The healthcare provider orders acyclovir (Zovirax), 250 mg/5 mL, to be given 250 mg per hour. The medication will have to be infused at _______ mL/hr

Answer:

250 mg/ 1 hr = 5mL/250 mg = 250 x 5 mL / 1 hr x 250 = 1250 mL/ 250 hr = 5ml/hr Question 12: The patient is ordered 1,000 units per hour of heparin. The medication arrives from the pharmacy as 50,000 units in 1,000 mL D5W. Therefore, this medication should be infused at __ mL/hr.

Answer:

50,000 units 1,000 mL = 1,000 units : X mL = 1,000,000 / 50,000 = 20 mL

Question 13: The patient is ordered sodium bicarbonate 44.6 mEq/50 mL, to be given at 10 mEq per hour. So, the infusion rate for this order is ________ mL/hr (to the nearest tenth).

Answer:

10 mEq / 1 hr x 50 mL /44..6 mEq = 10x 50 mL / 1hr x 44.6 = 500mL/ 44.6 hr = 11.2 ml/hr Question 14: There are 60 units of insulin in a 250 mL bag of NS. Based on this, the medication's concentration is __ units/mL.

Answer:

60 units / 250 mL = 0.24 units/mL Question 15: There are 75 units of insulin in 500 mL ½ NS. The concentration of this medication is __ units/mL.

75 units /500 500 mL = 0.15 units/mL Question 16: The patient is to receive voriconazole (Vfend), 200 mg/20 mL, to be given at 100 mg/hr. The infusion rate for this medication is __ mL/hr.

Answer:

100 mg / 1 hr x 20 mL/200mg = 2,000mL / 200 hr = 10 mL/hr

Question 17: The patient is ordered 4 units per hour of insulin. The medication arrives from the pharmacy as 400 units in 50 mL ¼ normal saline (NS). Therefore, the medication should be infused at ____ mL/hr.

Answer:
