Question:
What is IV infiltration? S/S? Steps to take if infiltration occurs?
Answer:
IV infiltration is when fluid such as saline gets in the tissues.
S/S - pallor, swelling, site feels cool, slowed infusion
Steps - Stop infusion, remove bad IV, elevate extremity, encourage ROM,
apply cold/warm compress, start new IV and monitor infusion in another
extremity
,Question:
What is the purpose of potassium iodine?
Answer:
It can be used to protect the thyroid from radioactive iodine caused by
unlikely radiological emergency
Question:
What is IV extravasation? Steps to take if extravasation occurs.
Answer:
Vesicant medication (K, Cl, dopamine, norepinephrine) gets into tissues.
Similar to infiltration but these leaking fluids cause tissue damage/necrosis
Stop infusion -> Leave bad IV so antidote can be infused through it -> Notify
MD -> start new IV in another arm
Question:
Infiltration vs extravasation
Answer:
Infiltration and extravasation both involve fluid leaking into surrounding
tissue, but infiltration involves non-vesicant fluids that generally do not cause
tissue damage, whereas extravasation involves vesicant medications that can
cause severe tissue damage or necrosis.
,Question:
What are magnesium supplements?
TX?
A/E?
S/S of magnesium toxicity
Antidote for magnesium toxicity?
Answer:
Magnesium sulfate, magnesium citrate, magnesium hydroxide
TX
1) hypo magnesia (mg < 1.5 mEq/L)
2) Torsade de Pointes (IV Mg is first line of TX)
3)Always put patient receiving electrolytes on heart monitor
4) Magnesium Sulfate Used in OB for cases of tocolysis which is stopping preterm labor
S/S - loss of DTR (deep tendon reflexes), respiratory depression, flushing,
cardiac arrest
Antidote - Calcium gluconate kept at bed side when administered magnesium
sulfate in case of OD.
A/E - muscle weakness, flaccid paralysis, suppress electrical signals through
AV node of heart, respiratory depression
, Question:
Important time benchmarks and safety precautions for PRBCs transfusion
What tubing to infuse blood through and how is it primed?
Answer:
Vital signs must be checked prior to start, 15 minutes after starting, after an
hour, and when transfusion finished
Sit with patient for 15 minutes to assess for allergic reaction to transfusion -
blood ran 2 mL/min first 15 minutes
30-minute window to infuse blood once received from blood bank
4 hours to infuse blood max
Only infuse blood through BLOOD tubing - NO MEDS OR OTHER FLUIDS.
Blood tubing primed with NS only.
2 nurses must verify patient name, blood type compatibility, expiration date
of PRBCs, and unit number
