Term 1 of 54
What action should the nurse implement when accessing an implanted infusion port for a client
who receives long term IV medications?
63 ml/hour
Rationale
To calculate the infusion rate, the dose of KCl is not used in the calculation. Using the total
volume of Normal Saline solution, 250 ml/4 hours = 63 ml/hour.
Document in the medical record that these normal findings are expected outcomes
Rationale
The results are all within normal range (BUN 10 to 20 mg/dl or 3.6-7.1 mmol/L (SI units),
serum glucose 70 to 110 mg/dl or less than 6.1 mmol/L (SI), and serum potassium 3.5 to 5.0
mEq/L or 3.5-5.0 mmol/L (SI units). The other actions are not indicated.
Insert a huber-point needle into the port
Rationale
An implanted infusion port needs to be accessed using a Huber-point needle (non-coring)
to be prevent damage to the self-sealing septum of the port. The other actions are not
necessary when accessing an implanted infusion port.
Infuse 10% dextrose and water at 54 ml/hour
Rationale
TPN should be discontinued gradually to allow the client to adjust to decreased levels of
glucose. Administering 10% dextrose in water at the prescribed rate should reduce the
client's risk of hypoglycemia until the next TPN solution is available. The other actions are
not indicated.

120
Rationale
8 grams = 8,000 mg prescribed dose.Using the formula, D/H x Q, 8,000 mg / 200 mg x 1 ml = 40 ml
of the 20% solution.Dilute the 40 ml to a 1:4 concentration for administration using ratio and
proportion, 1 : 4 solution :: 40 ml : XX= 160 ml total volume to administer.Subtract total volume of
160 ml - 40 ml of 20% concentration = 120 ml diluent is added to obtain a 1:4 concentration.
A client with septic shock receives a prescription for dDextrose 5% in Water (D5W) 250 ml
with dopamine (Intropin) 0.6 grams/250 ml at a rate of 5 mcg/kg/minute. The client's weight
is 148 pounds 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.)
A client with a gastrostomy tube (GT) receives a prescription for a 250 ml bolus feeding of
Glucerna60% enteral formula. The nurse should dilute the full-strength formula with how
many ml of water? (Enter numeric value only).
A loading dose of acetylcysteine (Mucomyst) 8 grams, which is available as a 20% solution
(200 mg acetylcysteine per ml) is prescribed by nasogastric tube for a client with
acetaminophen toxicity. How many ml of diluent should be added to the medication to
obtain a 1:4 concentration? (Enter the numerical value only. If rounding is required, round to
the whole number.)
A client receives a prescription for a dose of medication 300 mg IV every 6 hours. The
preparation arrives from the pharmacy diluted in a secondary infusion of 0.9% Sodium
Chloride (NaCl) 50 ml. The nurse plans to administer the dose over 20 minutes. How many
ml/hour should the nurse program the infusion pump to deliver the secondary infusion?
(Enter the numeric value only, rounded to a whole number.)
,Term 3 of 54
The nurse is administering an intravenous solution 250 ml to be infused over 2 hours. How many
ml/hour should the nurse program the infusion pump? (Enter numeric value only, whole number.)
21
Rationale
The accepted formula for figuring drops per minute is: amount to be infused in one hour x
drop factor/time for infusion (min ) = drops per minute. Using this formula: 1,000/8 hours =
125 ml/ hour 125 x 10 (drip factor) = 1,250 drops in one hour. 1,250/ 60 (number of minutes in
one hour) = 20.8 = 21 gtt/minute.
140
Rationale
Using the child's BSA, 0.7 m2, calculate the mg/dose, 600 mg x 0.7 m2 =420 mg/day/3 doses
= 140 mg/dose
10
Rationale
Convert units to milliunits, 20 units x 1,000 = 20,000 milliunits.Using D/H x Q = 30
ml/hour:X/20,000 milliunits x 1,000 ml = 30 ml/hour (60 minutes).X/20 = 30ml/60 minutes,
reduce to: X/2 = 1/2, and 2X = 20, so X = 10 milliunits/minute
125
Rationale
250 ml : 2 hours = X ml : 1 hour2X = 250X = 125 ml/hour
, Term 4 of 54
A client receives a prescription for inamrinone (Inocor) 0.75 mg/kg IV bolus to be delivered over
3 minutes. The client weighs 80 kg. Inamrinone is available for injection, 100 mg/20 ml. How many
ml of inamrinone should the nurse administer? (Enter numeric value only. If rounding is required,
round to the nearest whole number.)
83
Rationale
Calculate using Volume/Time: 500 ml/6 hours = 83.3 ml/hour = 83 ml/hour
12
Rationale
First calculate the mg/kg dosage needed:0.75 mg x 80 kg = 60 mg neededThen calculate:
Desired / Have x ml60 mg / 100 mg x 20 ml = 12 ml
100
Rationale
First convert hours to minutes:10 hrs x 60 = 600 minutesUsing the formula Volume/Time x
drop factor:1000 ml /600 minutes = 1.66666 x 60 = 100 gtts/minute
150
Rationale
The infusion rate is calculated as a ratio proportion problem.50 ml : 20 minutes :: X ml : 60
minutes20X = 30003000/20 = 150 ml/hour
