17

What are the functions of the small and large intestines?

A

Small intestine - digestion and absorption

Large intestine - movement, absorption and formation of faeces

18
Q

What are the 2 causes of a bowel obstruction?

A

Mechanical obstruction - occurs inside or outside the intestine, obstruction of bowel lumen.

Functional obstruction - tumour mass, impaction, adhesions from surgery, volvulus, ileus, peritonitis, massive ascites

19
Q

What is the nursing care of a lower GI bleed?

A

DRABCDE

Reassurance

NBM

IVT for rehydration

Medication

Query prep for surgery

Post op care if applicable

20
Q

What are the signs and symptoms of a small bowel obstruction?

A

Anorexia
Early feeling of fullness
Bloating
Tender abdomen
Tinkling bowel sounds +/- visible peristaltic waves
Intermittent cramping pain
Initial diarrhoea followed by constipation
Signs of fluid and electrolyte imbalance (tachycardia, tachypnoea, hypotension)
N&V
Passing of blood and mucous
Fluffy stools

21
Q

What sort of complications can a small bowel obstruction cause?

A
Hypovolaemia
Renal insufficiency 
Impairment of pulmonary ventilation 
Metabolic dysfunction
Strangulation of incarcerated hernias 

Can also cause bladder obstruction, metabolic acidosis and sepsis

22
Q

What are the features of a large bowel obstruction?

A

Luminal contents accumulate

Peristaltic activity can cause colic pain

Accumulating fluid causes distention

Peristalsis interferes with oxygen consumption

Danger of necrosis or perforation

23
Q

What is the treatment approach for a bowel obstruction?

A

Conservative approach

Rest and rehydration
IVT initially; recommence fluids slowly
Treat N&V
Analgesia, steroids, laxatives
NGT

Surgical intervention
Radiation used to reduce size and release obstruction

24
Q

What is the nursing management for a bowel obstruction?

A
Monitor for signs and symptoms of deterioration 
FBC
IV fluids and electrolytes
NGT to empty contents
Analgesia
Antispasmodics
Anticolonergics

Somastatin therapy to reduce GI secretions and increase absorption of water and electrolytes

25
Q

What are three common infections of the GIT?

A

Bacterial (salmonella, E.coli)

Viral (Hep A, norovirus)

Parasitic

26
Q

What is the most common cause of infectious diarrhoea in hospital patients?

What is the mortality rate if the infection lasts longer than 30 days?

A

Clostridium Difficile

As high as 30%

27
Q

What is the treatment for CDI?

A
Supportive care
Treat symptoms
Antibiotic therapy
Supplements
Prebiotics
Probiotics 
Surgery
Faecal transplantation
28
Q

What is a colostomy and what are the types?

A

Removal of cancerous tumour mass, sigmoid colon and rectum. Hole is made in abdomen and free end of colon pulled through and stitched.

Ascending
Descending
Transverse
Sigmoid

29
Q

What is an ileostomy and what are the complications/risks?

A

End of the ileum (lowest part of the small intestine) is formed into a stoma, usually on the lower right side of abdomen.

Skin breakdown
Liquid stools
Malabsorption risk due to inability to absorb nutrients prior to expulsion.

30
Q

What is the nursing care for a patient with a new stoma?

A

Preoperative education with stoma therapist

Check stoma postoperative - will be red with moderate oedema and some bleeding

Care of surrounding skin very important
