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 value only. If rounding is required, round
to the nearest whole number.)
2000
To calculate the amount of medication being delivered each hour: First convert
grams to mg: 1 gram = 1000 mg :: 4 grams = 4000 mgNext calculate number of mg
delivered/hour4000 mg : 250 ml :: X mg : 125 ml4000/X :: 250/12550000= 250XX =
2000 mg/hour
A 110-pound, adult female is admitted to the Emergency Center after receiving
burns to 40 percent of her body. Using the Parkland formula, the client's fluid
requirements for the first 24 hours after injury is calculated using Lactated
Ringer's 4 ml solution x Body weight (in kilograms) x Percent burn. The client
should receive one-half of the 24-hour calculated fluid volume in the first 8
hours of treatment. The nurse should set the infusion pump to deliver how
many ml/hour during the first 8 hours? (Enter the numerical value only. If
rounding is required, round to the nearest whole number.)
500
Using the Parkland formula, the client's fluid requirements for the first 24 hours after
injury is calculated using 4 ml lactated Ringer's solution x Body weight (in kilograms)
x Percent burnConvert 110 pounds to kg = .2 = 50 kg4 ml x 50 kg x 40 =
8,000 mlOne-half in first 8 hours = 4,000 ml4,000 ml / 8 hours = 500 = 500 ml/hour
,Amoxicillin 500 mg PO every 8 hours is prescribed for a client with an
infection. The drug is available in a suspension of 125 mg/5ml. How many ml
should the nurse administer with each dose?
a) 20 ml.
b) 4 ml.
c) 100 ml.
d) 10 ml.
a) 20 mL

A client experiencing ventricular tachycardia receives a prescription a
continuous infusion of dextrose 5% in water (D5W)1000 ml with lidocaine
(Xylocaine) 2 grams at a rate of 4 mg per minute. The nurse should program
the infusion pump to deliver how many ml/hour? (Enter numeric value only. If
rounding is required, round to the nearest whole number.)
120
First convert solution gram/ml to milligrams/ml: 2 gm/1000 ml = 2000 mg/1000 ml = 2
mg/mlNext calculate the number of mg/hour for the dose: 4 mg X 60 minutes = 240
mg/hourNext calculate the number of ml/hour needed to administer 240 mg/hour:
2000 mg: 1000 ml :: 240 mg : X ml2000/240 = 1000/XX = 120 ml/hour
The healthcare provider prescribes the adjustment of the IV hourly rate based
on the nasogastric tube (NGT) output every 4 hour for a client who had
abdominal surgery yesterday. From 1200 to 1600, the NGT output was 240 ml,
and the IV ofDextrose 5% in 0.45% Sodium chloride (D51/2 NS) was infused at
a rate of 100 ml/hour. At 1600 the nurse should regulate the IV to deliver how
many ml/hour to replace this fluid loss? (Enter numeric value only, using a
whole number.)
160
To calculate the hourly rate of IV fluid replacement based on the last 4 hours of NGT
output, the nurse should calculate an average hourly output by dividing 240 ml by 4
,hours = 60 ml NGT output every 1 hour.The nurse should then add the 60 ml loss
per hour to the present infusion rate of 100 ml/hr, totaling an infusion rate of 160
ml/hour for the next 4 hours
Nitroprusside sodium (Nipride) 50 mg is mixed in D5W 250 ml. The nurse plans
to administer the solution at a rate of 5 mcg/kg/minute to a client weighing 182
pounds. Using a drip factor of 60 gtt/ml, how many drops per minute should
the nurse regulate the infusion?
31 gtt/min.
62 gtt/min.
93 gtt/min.
124 gtt/min.
124 gtt/min.
Rationale
Convert pounds to kg: 182/2.2 = 82.73 kg.
Determine the dosage for this client: 5 mcg x 82.73 = 413.65 mcg/minute.
Determine how many mcg are contained in 1 ml: 250/50,000 mcg = 200 mcg per ml.
The client is to receive 413.65 mcg/minute.
There are 200 mcg/ml, so the client is to receive 2.07 ml/minute.
The nurse calculates the drip rate using the drip factor of 60 gtt/ml, then 60 x 2.07 =
124.28 gtt/minute
OR, using dimensional analysis: gtt/min = 60 gtt/ml X 250 ml/50 mg X 1 mg/1,000
mcg X 5 mcg/kg/min X 1 kg/2.2 lbs X 182 pounds.
The healthcare provider prescribes a continuous intravenous infusion of
Dextrose 5% in 0.45% sodium chloride ((D51/2 NS) with KCl 20 mEq / 1000 ml
to be infused over 8 hours. How many ml/hour should the nurse program the
infusion pump? (Enter numeric value only. If rounding is required, round to the
nearest whole number.) ________
125
Rationale
Using the formula, volume/time:
1000 ml/8 hours = 125 ml/hour
, A client is receiving a cephalosporin antibiotic IV and complains of pain and
irritation at the infusion site. The nurse observes erythema, swelling, and a red
streak along the vessel above the IV access site. Which action should the
nurse take?
Administer the medication more rapidly using the same IV site.
Initiate an alternate site for the IV infusion of the medication.
Notify the healthcare provider before administering the next dose.
Give the client a PRN dose of aspirin while the medication infuses.
Initiate an alternate site for the IV infusion of the medication.
Rationale
A cephalosporin antibiotic that is administered IV may cause vessel irritation.
Rotating the infusion site minimizes the risk of thrombophlebitis, so an alternate
infusion site should be initiated before administering the next dose. The other actions
are not indicated.
What action should the nurse implement when accessing an implanted
infusion port for a client who receives long term IV medications?
Cleanse the site with iodine solution.
Insert a Huber-point needle into the port.
Flush tubing with 5 ml of normal saline.
Place a sterile dressing over the port.
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.
A client receives a prescription for an intravenous infusion of Dextrose 5% in
0.45% Sodium chloride (D51/2 NS) 500 ml to be infused over 6 hours. The
nurse should program the infusion pump to deliver how many ml/hour? (Enter
numeric value only. If rounding is required, round to the nearest whole
number.)
