In the actual PSA they will make it clear as to what they're asking for, because you're right, I don't think will be prescribing 1580 mL, at the very least not for maintenance fluids

Chapter
Osteoporosis, otherwise known as thin bones, is a condition associated with high risk of low trauma fractures due to reduced bone mineral density. Osteoclast activity exceeds osteoblast activity, meaning that bone resorption is occurring at a greater rate than bone formation.

**Symptoms and Signs**

- Generally asymptomatic until a fragility fracture occurs
- Back pain
- Kyphosis (stooped posture)
- Fragility fractures

**Risk factors**

- Female sex
- Increasing age
- Smoking
- Corticosteroid use
- Low BMI (< 20-25kg/m<sup>2</sup>)
- Low body weight (<58kg)
- Vitamin D deficiency

**Protective factors**

- Higher BMI
- Exercise - mechanical loading stimulates bone formation

**Diagnosis**
Osteoporosis can be detected on dual-energy x-ray absorptiometry (DEXA) scan.
A T score of < -2.5 indicates osteoporosis

**Management**

- Fall prevention
- Vitamin D and calcium supplementation
- Hormone replacement therapy (postmenopausal women)
- Oral bisphosphonates

Fluid maintenance therapy in children

Paediatrics
The first 10kg of weight replaces fluid at a rate of 100 ml/kg/day.

The second 10kg of weight replaces fluid at a rate of 50 ml/kg/day.

Then any extra kg in weight above 20kg total weight is replaced at a rate of 20 ml/kg/day.

This patient weighs 24kg. Therefore he will need 1000ml for his first 10kg of weight, 500ml for his next 10kg of weight and another 80ml for the last 4kg.

Case Presentation:

A 6 year old boy is admitted to the paediatric ward with abdominal pain and nausea. Weight 24kg.

**On examination**
BP 102/64mmHg, HR 101, RR 22, patient is alert.

Mucus membranes appear moist.

Skin turgor is normal.

Capillary refill time is > 2 seconds.

Due to the boy's nausea he is unable to tolerate oral fluids. It is decided that IV maintenance fluids should be prescribed to ensure adequate hydration is maintained.

What **total** volume of 0.9% sodium chloride + 5% glucose should be prescribed for this patient's daily maintenance fluids?
