objective 5 (1) Flashcards
delivers fluids directly into a vein
commonly used to treat many different fluid and
electrolyte imbalances
intarvenous therapy
what are the clinical indications of IV therapy?
- Maintain or prevent fluid & electrolyte
imbalances
oral intake restricted
client can’t swallow/absorb med by
any other route
GI absorption impaired - Administer medications
- rapid drug effect needed
- Replenish blood volume
- Continuous therapeutic blood level
desired - Assist in pain management
what are the risks of IV therapy?
- phlebitis, ecchymosis, extravascular fluid infiltration, infection,
thrombosis, and venous spasm. - Systemic complications may also occur, such as bacteremia and
sepsis, air embolism, and pulmonary edema.
what are the benefits of IV therapy?
Giving drugs IV is rapid and effective
Drugs can also be delivered long term by continuous infusion, or
over short period, directly as single dose.
what are the commonly infused drugs?
- antibiotics
- thrombolytics
- histamine-receptor antagonists
- antineoplastics
- anticonvulsants
- cardiovascular drugs
what are the types of IV solutions?
isotonic
hypotonic
hypertonic
H2O & molecules suspended
(undissolved) substances i.e. blood cells
& blood products (albumin)
colloid
H2O & dissolved crystals i.e. salt
(sodium chloride) or sugar (glucose,
dextrose)
crystalloid
- same concentration of dissolved
substances as plasma (ECF) - RBCs does not shrink or swell
- Use- clients who can’t eat/drink for short
time
isotonic solutions
what are the types of isotonic solutions>
- 0.9% NaCl (NS -normal saline)
- 5% dextrose & H2O (D5W - glucose &
H2O) - Lactated Ringer’s (RL: E- solution)
provides more water than electrolytes, diluting the
ECF
* Use
* rehydrating clients (cause body to
retain fluid, draws fluid into cells
causing blood cells to swell)
hypotonic solutions
what are the types of hypotonic solutions?
- 0.45% NaCl (half strength saline)
- 0.33% sodium chloride
- more concentrated than plasma
- Draws water from the ICF into the ECF
- Use:
- Total Parenteral Nutrition – TPN
- D10W (Dextrose) or 3% Saline
- useful in treatment of hypovolemia
and hyponatremia
hypertonic solutions
how do we maintain therapy?
- Nursing responsibility to check continuous IV every
hour - Knowledge of the solutions being administered and
principles of flow - Assess for local and systemic complications
- Excessive IV fluids causes increased blood pressure and
central venous pressure
pulmonary edema
what are the S&S of pulmonary edema
↓SpO2, ↑respiratory rate, dyspnea, coughing up
pink frothy sputum, auscultation of dependent fine
crackles
what is the nsg care for pulmonary edema?
- Prevention: Use IV controller / pump to prevent accidental bolus.
- Treatment: Must be immediate. ↑HOB, vitals, administer
oxygen, notify prescriber. Anticipate - diuretics and slowed IV rates
at insertion site or systemically
infection
what are the S&S of infection?
Insertion site may become red, tender, swollen, or have
purulent drainage. Systemic signs and symptoms may
include malaise, fever, hypotension, or tachycardia
what is the nsg care for infection?
PVAD-short and midline catheters showing S&S of local
infection should be removed immediately. Monitor for signs
and symptoms of systemic infection
air enters circulatory system via
bubbles in tubing/solution running out
air travels to lungs
air embolism
what are the S&S of air embolism?
Palpitations, dyspnea, cyanosis,
hypotension, weak rapid pulse, loss of
consciousness, chest pain
what is the nsg care for air embolism?
- Stop infusion, administer oxygen
- position client on Lt side,
Trendelenburg position, call doctor
movement of previously stationary blood clot to lungs
pulmonary embolus
what are the S&S of pulmonary embolus?
Sudden chest pain, Cyanosis, SOB,
decreased B/P, Tachycardia, anxiety
IV needle/catheter slips out of vein or not inserted
into vein
results in fluid build-up in extravascular tissue
infiltration
