Q

List the 5 reasons for utilising feeding plans.

A

To:
1. Deliver daily calorie requirement (DER + RER)
2. Improve recovery time
3. Ensure a nutritionally balanced diet to maintain optimuum bodily functions
4. Prevent or correct nuritional imbalances
5. Prevent the body from catabolizing lean body mass

What information do you need in order to create a feeding plan?

A

What the:
* Normal feeding habits are (how often, amount etc, amount)
* Feeding routine is
* What diet is being provided
* Known allergies are
* BCS
* MCS
* VS diet diagnosis of type of diet + approval

Q

What are the 5 steps to creating a feeding plan?

A
  1. Ascertain what the normal feeding habits are; including routine + diet
  2. Find out from the owner any known allergies or medically relevant reasons to why their diet is being given
  3. Discuss with VS in charge, what diet should be offered - relevant to clinical condition
  4. Share BCS + MCS with VS - as they are subjective
  5. Record on patient’s client record + hospitilisation sheet the diet that must be fed + a list. of alternative foods that could be fed - if unavaliable

4 - Note, that there may be clinically relevant reasons for a high or low BCS or MCS score, which may alter the DCR (Daily Calorie Requirement)

Q

Work out how many grams a day does a 25kg border collie, on a selected diet of dry Hills z/d, with 3.6kcals per gram

Hills z/d = z/d = diet name

A

Work out RER
RER = BW (kg) x 30 + 70
= RER = 25kg x 30 + 70
= 820kcals p/24hrs

**Ascertain how many kcals in p/g of diet **
= Diet kcals p/g = 3.6kcal

Work out how many kcals p/24hrs
RER (Divided by) kcals p/g = diet kcals p/24hrs
= 830kcals p/g (divided by) 3.6 kcals p/gram
= 227.8g p/24hrs

**Meals required per day = usually 4 **but can be 6 (in paediatric patients)

Find kcals p/g p/24hrs (divided by) meals required per day = g per meal

= 227.8g p/24hrs (divided by) 4 meals
= 228.56.95g per feed

63
Q

True or False.

66
Q

What is meant by ‘propulsive aboral movement’ ?

A

Normal muscle contractions along the gastrointestinal tract, i.e. peristalsis

67
Q

What can an absence of propulsive aboral movements in the GI tract cause?

Intestinal impaction

68
Q

A
  1. Enteritis
  2. Hypocalcaemia

Enteritis = Inflammation of the SI

69
Q

What may critically ill patients often require prior to nutirional interventions?

A

Stabilisation!

70
Q

What potential methods could be required to stabilise a patient prior to nutritionally interventions, in critically ill patients?

A
  • Assessment + stabilisation of vital signs
  • IVFT
  • Oxygen therapy - if hypodynamically stable, otherwise the patient can go into hypovalemic shock, due to reduced blood flow to the GI tract
  • GA or Anaesthesia
71
Q

For non-critical patients, who have a history of anorexia, how many days do they need to be anorexic in order to be considered for nutritional support?

A

3 days +

72
Q

What can poor perfusion of blood to the GI tact, leading to a decrease in nutrient absorption + digestion, lead to?

A

Ileus!

73
Q

True or False.

Ileus can increase the risk of regurgitation + vomiting.

A

True!

74
Q

What 2 potential recurrent conditions can also be considered to increase the risk of regurgitation + vomiting in patients?

A
  1. Pancreatitis
    (due to naseua , pain + inflammation)
  2. Osteoarthritis
    (due to inflammation of GI tract bv’s)

Pancreas = produced digestive enzymes

75
Q

What 3 factors should you ensure, within the nursing role, to provide nutrition to patients?

A
  1. Patient’s recieve their Daily Energy Requirements (DER)
  2. Select a nutriontionally balanced diet, to meet Resting Energy Requirements (RER)
  3. Provide adequate nutrition, factoring in disease + dietary requirements
76
Q

What 5 affects can providing appropriate nutrition have for patients?

A
  1. Improved recovery times
  2. Ensure appropriate wound healing
  3. Maintain muscle + body mass
  4. Reduce risk of infection
  5. Maintain immune system
77
Q

Whe exactly should you count how long a patient may have been anorexic for, when asking a client?

A

Start from when the patient stopped eating - exactly (at home)

78
Q

True or False.
If the patient is already malnourished, nutritional support should not be instiuted until they are hemodynamically stable.

A

True!

79
Q

What is meant by hemodynamically stable?

A
  • Stable heart
  • Good circulation
  • Good blood pressure
80
Q

What nursing nutritional support should be offered to a patient that has been anorexic for 1- 2 days.

  • Monitor clinical condition - daily
81
Q

What nursing nutritional support should be offered to a patient that has been anorexic for 3 - 4 days.

A
  • Nutritional support liekly needed, if recovery is not imminent
  • Consider feeding tube placement - requiring anaesthesia
82
Q

What nursing nutritional support should be offered to a patient that has been anorexic for 5 days.

A
  • Nutritional support required
  • Place feeding tube
    or
  • Initiate parental nutrition
83
Q

Give 5 major reasons for implementing nutritional support to patients

A
  1. Anorexia
    (Has multiple causes; pain, depression, nausea or ileus)
  2. Inappetence
  3. Patients with a high, constant, catabolic state (like burn patients, as it takes a lot of energy + calories to heal)
  4. Inability to eat
    (Oral surgery, trauma to the jaw, skull fracture = feeding tube)
  5. Clinical conditions effecting:
    = Entire GI tract
    = Upper GI tract
    = Lower GI tract
84
Q

What are the 3 main types of supportive nutrition that can be afforded to patients?
