Medications: Intravenous, Insulin Administration Flashcards
Insulin- in basic terms what is it?
Insulin is a hormone produced by the pancrea
What does insulin enable cells to do?
It enables cells to use carbohydrates
Two issues relative to insulin in patients with diabetes include:
No insulin production
Insufficient insulin production.
Insulin varies in what:
Insulins vary in their onset and duration of action
Insulins are classified as:
- rapid acting
- short acting
- intermediate acting
- long acting
Patients treated with more than one insulin require what?
Patients treated with other insulins may require the mixing of the two insulins in one syringe.
Before administering insulin, be aware of:
Before administering any insulin, be aware of the onset time, peak, and duration of effects and ensure that proper food is available
The scale commonly used for insulin is
U100
which is based on 100 units of insulin contained in 1mL of solution
U100: what is it based on
which is based on 100 units of insulin contained in 1mL of solution
What is insulin also calibrated in:
An insulin syringe is also calibrated in units.
How does IV administration of drugs get to the body?
Intravenous (IV) administration of medications delivers the drug directly into the bloodstream
What kind of effect do medications administered intravaneously have?
Medications administered intravenously have an immediate effect.
What is the most dangerous route of administration?
The IV route is the most dangerous route of administration
Why is ____the most dangerous route of administration?
The IV route is the most dangerous route of administration because the drug is placed directly into the bloodstream, it cannot be recalled, and its actions cannot be slowed
What route of administration is used most frequently in emergency situations?
IV administration is the route used in most emergency situations when immediate onset of action is required
When medication is administered by infusion, the patient receives it at what rate?
the patient receives it at a defined rate (mL/hr) over a defined period of time
How does Sodium Chloride run intravaneously?
IV fluid, such as 0.9% or 0.45% Sodium Chloride may run continuously at a defined hourly rate
Other medications, such as insulin, vasopressors (increase blood pressure), heparin, or sedatives, are titrated (increased or decreased) depending on…
depending on specific parameters such as the patient’s clinical presentation, blood pressure, or laboratory values
What do meds administered via IV Bolus or Push involve?
This involves a single injection of a concentrated solution directly into an intravenous line
Medications via an Intravenous Bolus or Push administration rate is?
Although the administration rate varies, many drugs are administered over a 2-minute time frame.
Medications via Intermittent Intravenous
Infusion
The drug is mixed with a small amount of an intravenous solution, such as 50 to 100 mL of saline or dextrose, and administered over a short period at the prescribed interval
How is medications via intermittent IV infusion usually administered?
The administration is most often performed using an intravenous infusion pump,
What does the infusion pump require the nurse to do?
The administration is most often performed using an intravenous infusion pump, which requires the nurse to program the infusion rate (mL/hr) and prescribed volume into the pump.
Medications via Intermittent Intravenous Infusion may also be administered by?
Administration may be achieved by gravity infusion,
What does gravity infusion require?
requires the nurse to calculate the infusion rate in drops per minute (gtt/min).
Drop factor
represents the number of drops per mL a specific IV tubing set delivers
Who is drop factor determined by?
drop factor is determined by the manufacturer and printed on the IV tubing packaging
