Accepted Answer

Change mcg to mg, 1000 mcg = 1 mg
Use ratio and proportion to calculate the dose: 2 mg : 1 ml :: 0.25 mg : X ml
2X = 0.25 mg
X = 0.125 =0.13 ml

Question 2

he healthcare provider prescribes an intermittent infusion of nafcillin (Unipen) 800 mg IV for a pediatric client. The drug is dispensed in a concentration of 250 mg/ml, and the recommended infusion concentration is 40 mg/ml. When adding the prescribed do

Accepted Answer

16.8..First, calculate the amount of milliliters of medication needed to provide 800 mg of nafcillin. Prescribed dose (800 mg) divided by dose on hand (250 mg/ml) equals 3.2 ml
Next, determine the recommended concentration using equivalent fractions. 800

Question 4

A client admitted to the unit from the emergency room receives a prescription for an IV infusion of 0.9% sodium chloride 1,000 ml at 750 ml/4 hours. The IV administration set delivers 60 gtts/ml. The nurse should regulate the infusion to deliver how many

Accepted Answer

188...First convert hours to minutes: 4 hours x 60 = 240 minutes
Using formula Volume/Time x gtt factor: 750 ml/240 min = 3.125 x 60gtts = 187.5 (rounding to) 188 gtts/minute

Question 5

The nurse is preparing a tube feeding of Ensure 280 ml (50% solution). Full strength Ensure is available in a 240 ml can. The nurse should use how many ml of Ensure to prepare the feeding? (Enter numeric value for only. If rounding is required, round to n

Accepted Answer

140..Using the formula D/H (Desired % / % on Hand) x Total volume desired:
50/100 x 280ml = 0.5 x 280 ml = 140 ml Ensure + 140 ml water = 280 ml (50% solution)

Accepted Answer

206...Using the formula Desired % / on Hand % x Volume Desired = 75/100 x 275 = 0.75 x 275 = 206 Ensure
206 ml Ensure + 69 ml water = 275 ml (75% solution)

Question 8

Heparin protocol is prescribed for a client weighing 90 kg. Per protocol, the heparin loading dose is 60 units/kg IV rounded to the nearest 100 units, with a maximum loading dose of 4,000 units. The heparin vial is labeled 5,000 units/ml. How many ml shou

Accepted Answer

0.8.... Determine the client loading dose: 60 units x 90 kg = 5,400 unit.
Per protocol, use the maximum loading dose of 4,000 units, and calculate the client's dose using the formula D/H x Q = 4,000 units / 5,000 units x 1 ml = 4/5 = 0.8 ml
or Use ratio

Question 9

A client who has preeclampsia receives a prescription for an IV infusion of 0.9% normal saline with magnesium sulfate 4 gram/250 ml to be infused at a rate of 125 ml/hour. The nurse should administer how many mg/hour of magnesium sulfate? (Enter numeric v

Accepted Answer

2000....o calculate the amount of medication being delivered each hour: First convert grams to mg: 1 gram = 1000 mg :: 4 grams = 4000 mg
Next calculate number of mg delivered/hour
4000 mg : 250 ml :: X mg : 125 ml
4000/X :: 250/125
50000= 250X
X = 20

Question 10

A client with acute decompensated heart failure (HF) is to receive an IV infusion of 0.9% normal saline with inamrinone (Inocor) 0.1 grams/100 ml at a rate of 8 mcg/kg/minute. The client' s current weight is 183 lbs. The nurse should program the infusion

Accepted Answer

40...First convert the weight into kilograms: 183 pounds/2.2 kg = 83 kg
Next calculate the number of mcg/kg/minute: 8 x 83 = 664 mcg/min
Calculate the number of mcg/hour: 664 x 60 minutes = 39,840 mcg/hour
Now calculate the number of ml/hour needed to

Question 11

A client with impetigo receives a prescription for azithromycin (Zithromax) 500 mg PO on day 1, then 250 mg/day on days 2 through 5 for a total administration of 1.5 gram. The pharmacy has 250 mg tablets available. How many tablets total should the nurse

Accepted Answer

6...Using Desired/Have available formula:
