Module Assessment 3 Flashcards
(27 cards)
Types of Dietary Nutrient Interactions
Direct- alter absorption, metabolism, or excretion
Indirect- undesirable side effects
Phenytoin and Warfarin
low serum albumin
phenytoin- antipsychotic for seizures
warfarin- anticoagulant IV form of Coumadin
Grapefruit and cardiac meds
cytochrome c is inhibited by enzyme in grapefruit
serum drug levels may become toxic
Na and Li
alter renal absorption
high Na- Na and Li excretion
low Na- Na and Li retention
Zantac, protonix
anti gerd medications
b12, thiamin, and Fe
Antineoplastics
drug damages mucosal surfaces causing malabsorption
may damage rapidly proliferating cells-> stomatitis, esophagitis
Phenobarbital and phenytoin–>
Methotrexate—>
affects metabolism of nutrients
Phenobarbital and phenytoin–> Fe, Vit D, and K def
Methotrexate—> folate def
Lasix and K

______ effects of drugs
Vit K opposes —–>
Antagonizing
Coumadin
Abx may cause
Abx and diarrhea may destroy
may cause candidiasis and
destroy intestinal bacteria
cleocin—> c, diff overgrowth
Flagyl, lunesia, biaxin may cause
may cause dysguesia
Narcotics and antipsychotics may affect
intestinal peristalsis
NSAIDs, ASA may
irritate stomach mucosa
Corticosteroids, decadron
glucose intolerance
Article
Vitamin A: Essential for collagen production and tissue formation.
Vitamin C: Needed for collagen formation, immune cell function, and fibroblast growth; deficiency can delay healing.
Protein: Crucial for collagen synthesis; arginine aids protein building, wound strength, cell growth, and oxygen flow to wounds.
Iron: Important for collagen and hemoglobin production; oxygen delivery by hemoglobin is critical for healing.
Challenges to Healing: Poor nutrition, low fluid/food intake, and health issues can slow wound recovery.
Supplements: May help improve energy intake in patients.
Pressure Injury Prevention: Those at risk should maintain hydration and increase protein and energy intake.
Ways to prevent sarcopenia and what is it
age related muscle loss
have a lot of muscle when this starts and continuously build muscle and eat to compensate for protein loss
Nutrient needs for older adults
more protein to compensate for catabolism
less calories due to declining metabolic rate
Main nutrition interventions for older adults
push fluids and protein
encourage exercise
Atropic gastritis
B12 deficiency
there is less hydrochoric acid production in older adults and B12 needs acidic environment to be metabolized
What affects Nutrient Needs
Age, gender, diagnosis, wt loss, obesity; pt with hyper metabolic conditions have increased needs
Main concerns for older adults
dehydration—–> constipation
wt loss
What do you need to do before increasing protein for wound healing
meet calorie needs if not protein is turned into glucose instead of being used for wound healing
What is the same for all wounds
1) need to meet needs then increase protein
2) must be hydrated
3) glucose control
