PICC PICC Pharmacology & Medication Administration

Question 1

Which pH range of medications is considered vesicant and requires central venous access such as a PICC for safe administration?

Accepted Answer

pH less than 5 or greater than 9

Answer

Solutions with a pH less than 5 or greater than 9 are vesicants that can cause severe tissue damage and require central venous access like a PICC for safe delivery.

Question 2

A patient is receiving vancomycin through a PICC line. Which laboratory value must be monitored to ensure therapeutic dosing and prevent toxicity?

Accepted Answer

Serum creatinine and vancomycin trough levels

Answer

Vancomycin is nephrotoxic and ototoxic, so serum creatinine and trough levels must be monitored to ensure therapeutic dosing and prevent toxicity.

Question 3

Which medication classification is considered an absolute indication for central venous access due to peripheral vein toxicity?

Accepted Answer

Vesicant chemotherapy agents such as doxorubicin

Answer

Vesicant chemotherapy agents like doxorubicin cause severe tissue necrosis on extravasation and must be administered through confirmed central venous access such as a PICC.

Question 4

A PICC nurse is preparing to administer total parenteral nutrition (TPN). Which PICC lumen is the preferred choice for TPN infusion?

Accepted Answer

A dedicated lumen used exclusively for TPN

Answer

TPN should be administered through a dedicated lumen to prevent incompatibility reactions and reduce infection risk from co-infusion with other medications.

Question 5

Which two medications are commonly used together via PICC in outpatient settings and require close monitoring for potential incompatibility?

Accepted Answer

Ampicillin and gentamicin

Answer

Ampicillin and gentamicin are physically and chemically incompatible; they must not be mixed or infused simultaneously through the same PICC lumen.
