23
Q

When do you want to give biphosphonates and with what? Why?

A

In the morning, half an hour before meals, with a glass of water. This helps avoid esophageal erosion.

24
Q

Nursing considerations for Biphosphonates?

A
  • Interactions with aspirin and Nsaidds

* Can cause hypocalcemia, monitor serum calcium and ensure adequate Calcium and Vitamin D intake.

25
Q

Treatement for DDH? Why? How long?

A
  • Pavlik Harness
  • promotes development of a functional hip socket and well-formed femoral head through immobilization.
  • Worn continuously for 24 hours a day for 6 to 12 weeks (for hip dysplasia) (Can take off for one hour for bath time)
26
Q

When should client call HCP in regards to Pavlik harness?

A
  • Feet are swollen/blue
  • Skin is raw w/rash
  • Adjusting of straps
27
Q

What should you teach caregivers in regards to pavlik harness?

A
  • Harness should be snug (not tight)
  • Change diaper w/ baby in harness
  • Baby should sleep on back
  • Check skin folds for areas of breakdown
  • Wash w/ mild detergent and air dry
28

  • Neuromuscular- secondary to nm condition (e.g. cerebral palsy)
31
Q

Diagnosis for scoliosis?

A

A

10-15 degrees

33
Q

Range of degrees considered to be mild? Intervention?

> 40 - surgical correction with rod placement

35
Q

in Adams forward bend test, how does the child need to stand?

A

bends forward with the feet together and knees straight while dangling the arms.

36
Q

Treatment for scoliosis is aimed at what?

38
Q

A traditional or standard scoliosis brace that is most often used in the treatment of thoracic or major double curves
that has a visible neck piece
