Core PO1 - Nutrition & hydration Flashcards
Why is adequate hydration important in the recovery process?
Dehydration may complicate existing problems and slow the recovery process.
Why does dehydration affect the whole body?
Adults are 55-65% water.
2/3 of this fluid is found in the cells, hence dehydration affecting the whole body.
what are the effects of malnourishment on the recovery process?
It delays recovery and compromises the immune system.
Why does a patient with diarrhoea require fluid monitoring?
They will likely be dehydrated as a result of it.
Dehydration can cause a drop in BP and acute kidney damage.
What interventions can be put in place if an individual cannot keep fluids down?
- Intravenous fluids
- Catheterisation to closely monitor fluid balance
What is the skin turgor test?
This is a test for dehydration.
Pinch the skin on the back of the hand and if it does not snap back within the expected time frame, fluids should be given to prevent damage to the cells.
Older people have less skin elasticity and will therefore have a slower snap back.
