Q

Chris, a 2 year old boy, arrives in the emergency department with a history of vomiting for the last 24 hours. He has a low grade fever is lethargic and miserable. on urinalysis his specific gravity is 1.030 and has ketones ++. What does this suggest?

A

Gastroenteritis.
Specific gravity indicates whether you are dehydrated or not which this SG indicates that he is and an increase in ketones indicates the body fat is being broken down for energy and dehydration.

Q

It is now 48 hours since Chris was admitted to the ward. Chris was diagnosed with a viral gastroenteritis and has been steadily improving. Following a breakfast of toast and a drink of milk he has a large episode of loose diarrhoea. What would you like to do now?

A

Reduce or eliminate lactose from the diet
Perform a reducing substances test
Encourage fluids

17
Q

Chris has now been on a low lactose diet and lactose free milk. His diarrhoea has improved. His mother asks when should she start him on his normal diet again. What would you tell her?

A

Chris may be lactose intolerant so it is important to remain on a low lactose and lactose free milk diet until confirmation for healthy bowel functioning, decreasing discomfort and diarrhoea.

18
Q

Why are children more prone to dehydration than adults?

A

Infants experience more severe vomiting and diarrhoea than children and adults and they rely on someone else for their intake.
75-80% of an infants body weight is water

19
Q

List six signs and symptoms you may expect to see in an infant that is moderately dehydrated

A
  • Reduced urine output
  • Moderate thirst
  • Increased pulse rate and weak
  • Respiration is deep and may be rapid
  • Normal to low systolic blood pressure
  • Sunken fontanelle in infants
20
Q

Why is enteral (oral/NG) rehydration favoured over IV rehydration

A

Enteral rehydration is associated with significantly fewer major adverse events and a shorter hospital stay.

NGT is used for children with moderate dehydration
IV Hydration is used for children with severe dehydration

21
Q

Why can drinks such as lemonade make diarrhoea worse?

A

As it has a high solute load which can increase water loss into the lumen of the small intestine.

22
Q

Why can children with gastroenteritis present with metabolic acidosis?

A

As it occurs with severe diarrhoea as bicarbonate is lost in the stool

23
Q

What causes a disaccharide intolerance following gastroenteritis?

A

May occur secondary to damaged intestinal lumen which decreases or destroys the enzyme lactase

24
Q

Why can’t children suffering from a monosaccharide intolerance have glucolect?

A

Monosaccharides are your glucose and fructose.

If you have monosaccharide intolerance you are unable to transport and absorb glucose which is what glucolect is.

25
Q

Why do children with gastroenteritis need to be weighed before breakfast everyday?

A

For weight management and improvement

26
Q

As a staff member what can you do to prevent the spread of gastroenteritis to yourself and other patients?

A 
Good hand hygiene
Gloves
Gown
Parent education
Patient isolation
Clean equipment effectively
27
Q

What would be the significance of a positive result for reducing substances detected in a patients bowel action?

A

Lactose intolerance (disaccharide intolerance)

28
Q

Nursing care for gastroenteritis

A 
Daily weights
strict fluid balance- weigh nappies
BGL, K + Na monitoring
promote comfort
family support
antiemetics
NGT or IV cares
Bowel patterns
fluid and electrolytes
skin integrity
29
Q

Normal urine output

A

Children: 0.5-1mL/Kg/Hour
Infant: 2ml/Kg/Hour
