NURSADN8 Exam #1 Study Guide (Cardiovascular, IVAnd Respiratory) – Q’s And A’s
Identify primary factors in selecting peripheral IV site/size (4): Right Ans -
Solution (pH/osmolality), condition of veins, duration of IV therapy, and plan
of care (multiple sites/lumens needed)
For peripheral IV solutions, the pH should be between ______________ and the
final osmolality should be less than _____________ mOsm/L Right Ans - 5-9;
500
A *vesicant* is a substance that can cause inflammation, damage, and necrosis
with extravasation from blood vessels and contact with tissues. If an infusion
is NOT a known vesicant, it may be administered via _________.
A. Peripheral IV
B. Central Line Right Ans - A. Peripheral IV
*Rationale:* Vesicant drugs are medications that can cause serious damage to
the skin and muscle tissue if the drug comes into contact with them. Due to
this, it would be *safer to deliver the vesicant drugs through a central line
rather than through a peripheral line where there is a higher chance of drug
leakage*
Examples of _________ include *acyclovir, aminophylline, calcium salts,
chlorothiazide, dextrose solutions, vancomycin, and phenytoin* Right Ans -
vesicants
*Which needle gauge is this?*
- Used in high risk surgery
- bolus
- Emergency
- Need large vein Right Ans - 14g/16g
*Which needle gauge is this?*
- Used in trauma, surgery blood transfusion, CT dye
, - Need large vein Right Ans - 18g
*Which needle gauge is this?*
- Common size
- Suitable for contrast and blood Right Ans - 20g
*Which needle gauge is this?*
- Best for adult IV fluids, abx Right Ans - 22g
*Which needle gauge is this?*
- Small, shorter
- Geriatric and pediatric Right Ans - 24g
When would a *central line* be preferred over a peripheral IV? Right Ans -
If peripheral IV criteria are not met, if long term IV therapy is needed,
administration of known vesicants, total parenteral nutrition, chemotherapy,
central venous pressure (CVP) monitoring
A central line comes with more risk than a traditional IV. There can be
complications during the insertion procedure. And they have a higher risk for
infection. Which *central line* insertion site places a patient at *lower* risk
for pneumothorax and infectious complications?
A. Internal jugular central venous catheter
B. Subclavian central venous catheter
C. Femoral central venous catheter Right Ans - A. Internal jugular central
venous catheter
*Rationale:* An internal jugular central venous catheter (CVC) or a
peripherally inserted central catheter (PICC) is usually preferred to a
subclavian CVC (which has a higher risk of bleeding and pneumothorax) or a
femoral CVC (which has a higher risk of infection).
What is *IV Infiltration*? Right Ans - The leaking of IV fluid into the tissue
surrounding the vein. This occurs when IV fluids continue to be delivered
even though the tip of the catheter is no longer in the vessel or is blocked.
