Q

What is hypopituitarism?
p. 861-866

A

Insulin resistance and fluctuations in glucose levels

  • Insulin doses may need to increase
32
Q

Insulin considerations for Adolescent Psychosocial development/Noncompliance

A

(impulsiveness, mood swings, struggle for independence)

  • Care contracts, increased responsibilities, screen for depression, test glucose before driving, sex education and protection
33
Q

Insulin considerations: Developmental Approaches – Toddlers

A
  • Introduce the parents to other families with children with diabetes or find a support group.
  • Offer toddler choices of snacks and injection sites
  • Offer finger foods
34
Q

Insulin considerations: Developmental Approaches – Pre-School

  • Let child help choose foods, let child wipe skin for shots and glucose checks
  • Needle play with dolls (with supervision)
  • Play games to teach about hypoglycemia
35
Q

Insulin considerations: Developmental Approaches – Elementary

A
  • Play board and computer games about diabetes.
  • Attend diabetes camps.
  • Can follow a diet and help with management with close supervision.
  • Help with meal planning and preparation.
  • Can count carbohydrates.
  • Can administer or begin assisting with administration of insulin (drawing up and injecting); performing fingersticks with supervision.
  • **Does not fully comprehend how doing something now affects long-term outcomes (good diabetes control prevents complications later) **
  • If the child has electronic devices (phone, tablet, etc.), can download and use diabetes and carbohydrate monitoring apps
36
Q

Insulin considerations: Developmental Approaches – Young Adolescents

A
  • Support groups, negotiate plans to allow increasing responsibility for management with supervision
  • If the child has electronic devices; download diabetes management apps
  • Impulsiveness, mood swings, struggle for independence and body image are key influencing factors and can lead to noncompliance issues: care contracts can be used to foster accountability and increase compliance
  • Screen for depression, test glucose before driving, sex education and protection
37
Q

Insulin considerations: Developmental Approaches – Older Adolescents

A

Should begin to be independent with care by about 16 years. May still need help with insulin dosing decisions.

38
Q

Phenylkentonuria (PKU)
p. 893

A
  • Autosomal recessive disorder of metabolism that affects the body’s ability to use protein.
  • Must be detected early (is screened in newborn screenings), because if untreated it can lead to brain damage and developmental delay; autism spectrum-like behaviors
  • Diet low in phenylalanine; proteins and aspartame (artificial sweeteners)
    ** Fruits and vegetables are good, Lofenalac formula, carbs
    See the “Target” diet below for best options of acceptable foods
39
Q

Precocious Puberty
p. 868-869

A

Precocious puberty is when a child’s body begins puberty too soon, and is considered to begin before age 8 in girls and age 9 in boys. Administer hormone to stop puberty until they reach appropriate puberty time.
