Which route of medication administration does not pass through the digestive tract?

A. Skip manual checks since barcoding ensures accuracy: Barcoding significantly reduces errors but is not infallible. System errors, mislabeling, or scanning failures can occur, so skipping verification can compromise patient safety.

B. Use the barcoding system only for high-risk medications: Barcoding should be applied to all medications to ensure consistency and safety, not limited to high-risk drugs. Limiting its use increases the potential for errors with routine medications.

C. Rely solely on the barcoding system for verification: While barcoding aids in verification, nurses must also apply clinical judgment and confirm correct patient, medication, dose, route, and timing. Sole reliance on technology can miss errors the system does not detect.

D. Conduct a manual check of the medication with the MAR before administration to ensure the medications match: Performing a manual comparison between the medication and the MAR provides an additional safety layer. This step verifies that the correct drug, dose, and route are administered to the right patient, complementing the barcoding system.

A. Hypotonic solution: Hypotonic fluids cause water to move into cells, which may lead to cellular swelling or hemolysis if infused improperly. They do not directly cause tissue necrosis, blistering, or ulceration at the IV site. Local tissue injury of this severity is not typical.

B. Vitamin infusion: Most vitamin infusions are considered non-vesicant and are diluted to reduce irritation. While mild local irritation may occur, they do not produce the severe tissue damage associated with blistering or ulceration. Tissue necrosis is not an expected effect.

C. Vesicant: Vesicant medications cause severe tissue injury if they leak into surrounding tissue. Extravasation can result in blistering, ulceration, necrosis, and long-term tissue damage due to direct cytotoxic effects. Immediate intervention is required when vesicant extravasation is suspected.

D. Isotonic fluid: Isotonic fluids have a similar osmolarity to plasma and are generally well tolerated by peripheral veins. They do not disrupt cellular integrity or cause local tissue destruction. Blistering and ulceration are not associated with isotonic IV solutions.
