Answers)
IV Therapy Skills
Answer: • Initiate a peripheral venous access IV infusion
• Changing an IV solution container and administration set
• Monitoring an IV site and infusion
• Changing a peripheral venous access dressing
• Capping for intermittent use and flushing a peripheral venous access device
• Drip rate and infusion pump calculations (In lab)
z
Purpose of IV therapy
Answer: • Maintain daily fluid and electrolyte balance.
• Replace fluid and electrolyte losses
• Correct fluid and electrolyte imbalance
• Provide access to venous system for medication administration
• Everyone who's admitted to the hospital gets an IV
When dextrose or saline (solute) is diluted in
Answer: water for injection (solvent), he result is an IV solution that can be
administered to maintain the normal blood plasma.
Blood concentration is described in terms of
Answer: osmolarity and is measured in millOsmols per liter, or mOsm/L.

IV fluids are concentrated and classified as
Answer: isotonic (the same osmolarity as blood, hypotonic (lower osmolarity than
blood, or hypertonic (higher osmolarity) than blood.
Osmolarity
Answer: • Osmolarity-the concentration of a solution expressed as the total # of
solute particles per liter.
• Blood concentration is described in terms of osmolarity and is measured in
millOsmols per liter, or mOsm/L.
• IV fluids are concentrated and classified as isotonic (the same osmolarity as blood,
hypotonic (lower osmolarity than blood, or hypertonic (higher osmolarity) than
blood.
o Isotonic osmolarity = same osmolarity as the blood
o Hypertonic: higher osmolarity than the blood
• Normal saline is used to maintain someone's blood volume
• Normal Blood Osmolarity 280-320 mOsm/L
o Not all solutions are labeled hypertonic or hypotonic so use this number as your
reference
• Need to know pt's blood osmolarity/fluid electrolyte status so we know which
solution to use
If you had a patient with hypotension and were ordered a fluid bolus 5mL D5W/1 hr
and were also diabetic, is there an issue here?
Answer: o Yes, may or may not be able to give this fluid and should question this
order
o Most diabetics can't tolerate this
Hypotonic solution
Answer: use when the patient's blood is too concentrated (ex. hyperglycemia)
Hypertonic solution
Answer: use when loss of electrolytes (ex. vomiting or diarrhea)

IV Therapy :
• Absorption into bloodstream is immediate (rapid onset)
• Medications have immediate physiological response
• Peripheral IV (PIV)
o Most common type of IV
o Short term therapy
o Placed in the superficial veins of the hand and forearm generally
o IV fluid, medication, blood products
3 ways to give medications
Answer: o IV Push-given over 2-5 minutes, works immediately
o Pump infusion-given with control using automated pump that can calculate the
amount of time and rate you would like to admin. Med
o Gravity infusion-used in certain community hospitals, nursing homes, infusion
usually given over slightly longer period of time, less exact than automated pump,
relies on nurse to make sure it is set properly
IV orders
Answer: -Always check the health care provider's most current order (Usually
renewed every 24hrs at a minimum)
-Components of correct IV order
• Written by legally authorized health care provider (HCP)
• Includes:
o Date & time order is written and signature of authorized HCP
o Type of solution and/or additive
