Administering IV fluids

Intermittent IV infusion

Medication mixed in 50- 250ml solution

Give fraction of an hour

Administering IV fluids

Give small amount of medication either concentrated or diluted

This injection last a short time

1-2 min in emergent and non-emergent situations

Critical care unit

care for ct with peripheral IV lines and central venous access devices

Always need to follow the provider prescription when

regulating an IV fluid infusion rate

type of fluid

Always need to follow the provider prescription when

regulating an IV fluid infusion rate

A single, relatively large quantity of a substance, usually one intended for therapeutic use, such as a dose of a drug injected intravenously.

bolus

IV flow rate

I will give a large volume IV bolus rapidly and over a short period of time

to replace fluid loss resulting in

dehydration

shock

hemorrhage an escape of blood from a ruptured blood vessel, especially when profuse.

burns

trauma

Fluid bolus

monitor client carefully for

wheezing

dyspnea difficult or labored breathing.

other indications of fluid overload

Large volume IV bolus

Use a large gauge andro catheter

or central line to allow:

Rapid infusion of the fluid

Large volume IV bolus example

250 ml of dextrose 5% in 0.45% sodium chloride

the ct needs to receive this over 15 mins

you will determine the flow rate in Ml per hour to ensure that the ct receives the appropriate amount of fluid

*Dextrose=the dextrorotatory form of glucose (and the predominant naturally occurring form).

Large volume IV bolus example

Dextrose 5% in 0.45% sodium chloride

D5w 0.45% NaCL

250Ml over 15min

*Dextrose=the dextrorotatory form of glucose (and the predominant naturally occurring form).

Check dosage with another nurse

IV heparin

heparin is only available for subcutaneous or IV injections

Anticoagulant blood thinners prevent or reduce coagulation of blood, for

MI to prevent the formation of blood clots.

IV heparin

Venous thrombosis IV heparin helps to prevent additional clot formation.

IV heparin

Administer an initial IV bolus for heparin then begin a continuous IV infusion using a electronic infusion pump.

The provider will base the dosage of the cts weight in kilograms

He will prescribe the initial IV bolus dosage in units per kilogram

and then the continuous IV infusion per kilogram per hour

IV heparin

for a continuous Iv infusion you need to determine how many ML per hour to deliver

IV magnesium sulfate

electrolyte that activates many intracellular enzymes

IV magnesium sulfate

helps regulate skeletal muscle contractility and blood coagulation.

IV magnesium sulfate

important in the tx of acute

MI

Cardiac arrest

sezeires secondary to eclampsia

pre-term labor

magnesium deficiency

IV magnesium sulfate

When administering IV, use and electronic infusion pump.

Monitor clients cardiac and neuromuscular status

as well as serum magnesium level

IV magnesium sulfate

Moniter for HTN

depressed cardiac function

depressed or absent deep tendon reflexes

Respiratory depression

a provider will prescribe a dose specific to the clients status

IV magnesium sulfate

a provider will prescribe a dose specific to the clients status

(ex) they may prescribe a one time IV bolus in mg/kg

or a continuous IV infusion in mg/hr

foe a continuous IV infusion determine how many ml per hour to deliver.

IV Labetalol

Trandate

IV Labetalol Trandate

3rd generation adrenergic receptor blocking agent with alpha and non-selective beta activity

IV Labetalol Trandate Alpha blockade

vasodilation which decreases peripheral resistance and lowers bp

IV Labetalol Trandate Beta blockade

decreases hr mi yo cardial contractility

rate of conduction through the AV node

vasodilation effect that makes this medication effective in severe hypertension

Admister Labetolol

in a critical care unit using an electronic infusion pump.

In this step you will frequently check a cts vital signs and continuous monitor cardiac status

Admister Labetolol IV

Monitor the client for

Hypotension

brady cardia

nausea

dizziness

sweating

Admister Labetolol IV ex

A provider prescribes a dose specific to a clients status. He may prescribe a 1 time IV bolus in mg, or a continuous IV infusion in mg per min. For the continuous IV infusion, you need to determine how many ML/hr to deliver

IV Labetalol Trandate

Adrenergic Antagonist (blocking agent)

IV Labetalol Trandate

Anti hypertensive

severe hypertension

IV: bolus= mg

continuous IV infusion mg/min

IV dopamine

is an alpha and beta adrenergic agonist.

It activates beta 1 receptors in the heart

increase cardiac output, which leads to increase tissue perfusion.

dopamine activates

dopamine receptors in the

kidneys which dilates the renal vessels and leads to an increase glumeralar filtration rate and urinary output

IV dopamine

makes it useful in the tx of

heart failure

cardiogenetic

septic shock.

IV dopamine

where's theres a need for

cardiac stimulation

rasopresser action

Administer dopamine in a critical care unit

Using an electronic infusion pump

here you will check vital signs

and continuously monitor cardiac status

Administering dopamine IV

carefully monitor the clients cardiac status observing for:

tachycardia

dysrhymia

agina pain

MI possibly

High doses of dopamine

alpha 1 activation leading to local vasoconstriction

monitor pts IV site closely for extravasation

follow facility policy if this occurs

monitor pts IV site closely for extravasation

for ex

A provider prescribes a continuous IV infusion in mcg/kg/min. For continuous IV infusion, you need to determine how much ml/min to administer.
