Weight loss indicates an increased loss of _______ from the body cell mass in individuals who are malnourished. | protein |
What is the major protein synthesized by the liver? | albumin |
normal serum albuin level | 3.5-5.0 g/dL |
5 physical findings associated with nutrition deficiency | Hair - brittle and dry Nails - brittle Skin - dry; poor skin turgor Eyes - dry Heart - size: large = tachycardia, small = decreased output |
What is the most common complication of TPN therapy? | Hyperglycemia |
What nutrition includes the ingestion of foods orally and the nonvolitional delivery through a tube into the GI tract? | Enteral |
3 examples of patients who enteral nutrition would be contraindicated | GI tract obstruction; paralytic illeus; diarrhea |
PPN | peripheral parenteral nutrition: 7-10 days, no surgery involved in placement, lower concentrations - metabolic complications are fewer; no weight gain; 10% glucose |
TPN | total parenteral nutrition: can stay in for weeks or months; complete nutrition - can increase weight; higher dextrose amounts - will need to taper them off of |
Cancer treatment goals depend on situation | Curative Palliative |
Cycle specific | designed to disrupt a specific biochemical process (effective only during specific phases of cell cycle) |
Cycle non-specific | their prolonged action is independent of the cell cycle (allows them to act on both reproducing and resting cells) |
Combination Therapy | Mainstay of cancer therapy |
Antineoplastic selection depends on: | Patient age Overall condition Tumor type Allergies or sensitivities Stage of the cancer |
Antineoplastic Drug classifications | Alkylating agents Antimetabolite agents Mitotic inhibitors (Vinca alkaloids) Cytotoxic antibodies Podophyllotoxin derivitives Pacific yew tree derivatives |
biological response modifiers | Enhance body’s ability to destroy cancer cells Enhance immune response to tumors by altering the way cells grow, mature and respond to cancer cells. Interferon, Interleukins |
Routes of Administration | Most commonly administered I.V. – using peripheral, or central veins Can be administered by oral, subcutaneous, intrathecal, I.M., and intra-arterial, or intra-cavitary routes |
Chemo via other access devices | Administration of chemotherapy via central lines, implanted ports, other routes, etc. |
Common Side Effects of antineoplastics | Venous fragility Alopecia Diarrhea Altered nutritional status d/t N&D Anorexia or taste alteration Fatigue |
Acute Side Effects of antineoplastics | Hypersensitivity or anaphylaxis Extravasation ( IV related) Stomatitis and mucositis Nausea and Vomiting Myelosupression (Neutropenia, Thrombocytopenia, Anemia Toxicities |
Peripheral IV Catheters: | Appropriate for most chemotherapy Should NOT be used for continuous vesicants due to risk of infiltration and extravasation. Definition of vesicant Extravasation is leakage of vesicant substance into tissues - irritating DO NOT use butterfly needles – |
Choosing the correct vein | Fully assess the hand and forearm for appropriate vein. Selecting a vein that’s soft and pliable Insert I.V. catheter proximal to recent puncture sites – prevents drug leaking Use antecubital fossa and back of hand as last resorts |
Avoid with peripheral access: | upper extremities with impaired venous circulation arms with functioning shunts, grafts, or fistulas for dialysis. using the arm on same side as previous mastectomy, if possible damage to superficial tendons and nerves, |
Flushing | After infusion complete, infuse at least 20mL of NS through the catheter before discontinuing I.V. line; prevents drug leakage into the tissue as the catheter is removed (called “drug tracking”) and minimizes future vein damage |
True or False: We should wear protective clothing when handling body fluids from the patient for 48 hours after chemo treatment given. | True |
Compression and Compartment | tightness in the patient’s arm – usually complain of numbness and tingling in the swollen area (due to large quantities of I.V. solutions entering the tissue indicates a nerve compression injury) NOTIFY DOCTOR IMMEDIATELY!! |
Infiltration: | swelling around I.V., cool to touch along with blanching and possible change in I.V. flow rate |
The 3 C's related to inflitration | Cut off (the solution) Counteract (effects of the drug) Contain (the affected area) |
Extravasation S | Initial signs may resemble those of infiltration – swelling, pain, and blanching Blood return is an inconclusive test Symptoms can progress to: blisters, skin, muscle, tissue and fat necrosis; and tissue sloughing. |
What do you do for an etravasation emergency? | STOP the infusion. Check facility policy to determine if I.V. cath removed or left in place to infuse corticosteroids or specific antidote. NOTIFY the doctor INSTILL the appropriate antidote according to facility policy |
Post-Extravasation action | Continue to visually monitor the site and document its appearance and the patient’s response. |
What can the LPN do? | Watch for infiltration Check for signs of hypersensitivity reaction Instruct patient to report burning, stinging, or pain at or near the site Observe for streaky redness along the vein or other skin changes |

Rule of Thumb 1: | If clients can’t eat enough food to meet at least 50% of daily nutritional needs tube feedings should be considered. |
Rule of Thumb 2: | Parenteral nutrition can be discontinued when at least 70-75% of energy needs are being met by oral intake, tube feedings or both |
