Antineoplastic Agents (Chemotherapy) Flashcards
(36 cards)
What are antineoplastic agents?
Drugs used to treat cancer
Principles of chemotherapy:
- _________ because cancer cells will ______ if chemo is given at _____ dose. Genetic factors may also contribute to resistance.
- _______ drugs are used to avoid _______. Different drugs are used for different parts of the cell cycle phases.
- Cannot administer drugs for too _______ because of how they affect the ______ _____, thus affecting the white blood cells, thus affecting _______.
- Must wait for white blood cell cycle to ____ _____ immune cells before __________ _____ to avoid ______
Principles of chemotherapy:
- Resistance because cancer cells will mutate if chemo is given at low dose. Genetic factors may also contribute to resistance.
- Multiple drugs are used to avoid toxicity. Different drugs are used for different parts of the cell cycle phases.
- Cannot administer drugs for too long because of how they affect the bone marrow, thus affecting the white blood cells, thus affecting immunity.
- Must wait for white blood cell cycle to produce more immune cells before administering more to avoid toxicity.
Steps to safely administering chemotherapy: (5)
- Know patient’s actual height and weight
- With another nurse, calculated patient’s body surface area
-Check labs/tests (LFT, kidney, wbc)
-Check blood (CBC, peak, and trough)
-Check for adequate blood return before administering chemo
Personal protective equipment (PPE) for the nurse.
Gloves- must be latex or nitrile, change every 30 min. 2 pairs used
Gown- disposable, line free. 2nd pair of glove over cuff
Eye and face mask- (PR mask, not surgical)
G0
Resting phase, cells are not replicating
G1
Enzymes necessary for DNA synthesis are produced (first gap phase or postmitotic phase)
S
DNA synthesis phase; DNA synthesis takes place, from DNA strand separation to replication of each strand to create duplicate DNA molecules.
G2
RNA and specialized proteins are made (second gap phase or premitotic phase)
M
Mitotic phase; prophase, metaphase, anaphase, and telophase. Cell divied and reproduces into two daughter cells.
Antimetabolite drugs are ____ ____ ___.
What phase are they?
What do they do?
Cell Cycle specific (S PHASE) inhibit protein synthesis.

Methotrexate and Fluorouracil
Antimetabolites
-Methotrexate (IV, IM, PO, Intrathecal)
