Question

Question 1 A nurse is preparing to 0.2 L of normal saline for 16 minutes to a client with severe dehydration. The drop factor is 10 gtts/mL. At how many ml/hr should the Xinfusion pump be set? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) uestion 2 A nurse is preparing to administer half a liter of normal saline to be infused from 0015-0415 for an elderly client with dehydration. The drop factor is 20 gtts/mL. How many drops per minute should the nurse set the IV to infuse? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) estion 3 A nurse is preparing to infuse dopamine at a rate of 18 mL/hour to maintain a systolic blood pressure above 90 mm Hg to a client with a very low blood pressure. The client weighs 55 kg. The available dose comes in 200 mg in 250 mL of 5% dextrose in water (DSW). How many hours is needed to complete the infusion? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer 1

Question number 1

The amount of fluid to be infused is 0.2 liter = 200 milliliter

Time in which it has to be infused = 16 minutes

Drop factor given is = 10 gtts / milliliter

So on putting values in above formula –

(200/16) * 10 = 125 gtts per minutes

From above rate of 125 gtts per minutes we can get rate for 1 hour (1 Hour = 60 minutes)

So 125* 60 = 7500 gtts per hour is the rate to be set

Since 10 gtts = 1 milliliter , we can use this to get amount to be infused in milliliter.

Hence 7500/10 = 750 ml per hour

Infusion pump has to be set at a rate of 750 ml per hour in order to infuse 200 ml over 16 mintues with drop factor of 10 gtts per milliliter.

Question number 2

This question is not having complete information regarding regarding time duration over which saline has to be infused, and there is no information regarding 001500415 or its specification, without which it is not possible to attempt question.

Question number 3

IV order is - dopamine 18 ml per hour.

The preparation available is 200 mg in 250 ml of 5% dextrose

Patients body weight is 55 kilograms

Formula for IV Drugs in micro grams is

Dose in micro gram per minute per kg body weight =

(Milligram/ milliliter) X( 1000 micro gram/ 1 milliliter)X(milliliter/ 1 hour) X (1 Hour/ 60 Minutes) Divided by Patients weight in kilograms

On putting values in given formula-

(200 mg /250 ml)* (1000 mcg /1ml)* (18 ml/ 1 hour) * ( 1 hour/ 60 minutes) Divided by 55

= 240/55

= 4.36 micro gram per kg body weight per minute

So patient weighing 55 is getting a dose of 4.36 X 55 X 60= 14, 388 micro gram per hour

= 14388/ 1000 = 14.38 ( nearly 14.4 milligram) per hour (since 1 Milligram = 1000 micro gram)

Total dose in 250 ml dextrose is 200 milligram hence at the rate of 14. 4 milligram per hour

it will be sufficient for

200/ 14.4 = 13.88 hours

Since 1 hour is of 60 minutes so converting decimals will give 13 Hours 50 minutes

So approximately 13 hours 50 minutes will be required to infuse whole solution at the given dose and rate to maintain patients blood pressure above 90 mm of Hg.
