A client with septic shock receives a prescription for
dextrose 5% in water with dopamine (Intropin) 0.6
grams/250 ml at a rate of 5 mcg/kg/minute. The client's
weight is 148 lbs. The nurse should set the infusion pump
to deliver how many ml/hour? (Enter numeric value only. If
rounding is required, round to the nearest whole number.)
- ANSWER-8
First convert the weight into kilograms: 148 pounds/2.2 kg
= 67 kg. Next calculate the number of mcg/kg/minute: 5 x
67 x 1 minute = 335 mcg/min. Calculate the number of
,mcg/hour: 335 x 60 minutes = 20,100 mcg/hour. Now
calculate the number of ml/hour needed to administer
20,100 mcg/hour: 600,000 mcg : 250 ml :: 20,100 mcg : X
ml 600,000/20100 :: 250/X 600,000X = 5,02500 X = 8.375
(rounded to) 8 ml/hour.
A client with type 2 diabetes is receiving metformin
(Glucophage) 1 gram PO twice daily. The medication is
available in 500 mg tablets. How many tablets should the
nurse administer? (Enter numeric value only.) - ANSWER-
2
Using the known equivalent, 1 gram = 1000 mg, the nurse
should first convert the dose to the same unit of
measurement, which is 1 gram = 1000 mg. Using the
,formula, Desired / Available x 1 tablets: 1000 mg / 500 mg
x 1 = 2 tablets
A client with Mycobacterium avium complex (MAC) is
receiving an infusion of 5 % dextrose in water with
amikacin (Amikin) 0.572 grams/100 ml every 12 hours.
The nurse prepares the dose of amikacin using a vial
labeled, 250 mg/ml. How many ml should the nurse add to
the infusion? (Enter numeric value only. If rounding is
required, round to the nearest tenth.) - ANSWER-2.3
First convert gram to milligram: 1 gm = 1000mg .572 gram
x 1000 = 572 mg. Next use the formula D/H x Q: 572/250
x 1 = 2.288 (rounded to) 2.3 ml.
, A client with pericardial effusion has phrenic nerve
compression resulting in recurrent hiccups. The healthcare
provider prescribes metoclopramide (Reglan) liquid 10 mg
PO q 6 hours. Reglan is available as 5 mg/5 ml. A
measuring device marked in teaspoons is being used.
How many teaspoons should the nurse administer? -
ANSWER-2
First, using the formula, Desired dose/dose on Hand x
Quantity of volume on hand (D/H x Q), 10 mg / 5 mg x 5ml
= 10 ml. Next using the known conversion of 5 ml = 1 tsp:
5 ml : 1 tsp :: 10 ml : X : 1 / X 5X = 10 X = 2
A client is receiving alprazolam (Xanax) 0.75 mg PO BID
for anxiety. Alprazolam is available in 0.5 mg scored
