NRSG257 – EXAM REVISED STUDY GUIDE
Children: 0-14 years of age
What are the major issues faced with children in health?
- Preventable mortality
- Morbidity
- Vaccine preventable disease
- Adult conditions which originate in childhood
- Family and social functioning.
Injury – leading cause of mortality and morbidity after the first
year of life. Asthma: is the most chronic illness in children and
principal cause of hospitalization.
What morbidities are associated with children?
- Birth defects – neural tube defects (spina bifida),
structural defects and visual and hearing impairments.
- Low birth weight - <2500 grams = 6.4% (very low birth
weight <1500 grams =0.5%)
- Prematurity - <37 weeks gestation
- Asthma
- Childhood disability – (PKU, CF) early identification screening
Vaccines – prevent diseases
Adult conditions which originate in childhood:
- Nutrition and physical activity some children are
becoming more overweight an less physically active =
implications for future health planning
- Exposure to sunlight – highest rate of skin cancer in the world
- Oral health – fluoride has improved oral health
Family and social functioning:
- Parents and carers – parenting has a profound and
lasting impact on health, development and wellbeing
- Mental health – affects 1 in 5 children and young people
- Child abuse and neglect – the tip of the iceberg
Services in children’s health care:
- Early childhood health services
- Family carer centers
- Residential family care services
- Child and family teams
- Child protection services
- Hospital services
- Children’s units in general hospitals
- Children’s hospitals
- Outreach programmes.
Puberty:
- Young people become physically mature and capable of
reproduction
- Girls average is a two year lead on boys
- BMI is one of the strongest indicators of timing of girls puberty
- Female puberty usually takes 2-4 years to complete in
the following sequence’ budding of breasts, growth
spurt, menarche – first

NRSG257 – EXAM REVISED STUDY GUIDE

Children: 0-14 years of age What are the major issues faced with children in health?

  • Preventable mortality
  • Morbidity
  • Vaccine preventable disease
  • Adult conditions which originate in childhood
  • Family and social functioning. Injury – leading cause of mortality and morbidity after the first year of life. Asthma: is the most chronic illness in children and principal cause of hospitalization. What morbidities are associated with children?
  • Birth defects – neural tube defects (spina bifida), structural defects and visual and hearing impairments.
  • Low birth weight - <2500 grams = 6.4% (very low birth weight <1500 grams =0.5%)
  • Prematurity - <37 weeks gestation
  • Asthma
  • Childhood disability – (PKU, CF) early identification screening Vaccines – prevent diseases Adult conditions which originate in childhood:
  • Nutrition and physical activity – some children are becoming more overweight an less physically active = implications for future health planning
  • Exposure to sunlight – highest rate of skin cancer in the world
  • Oral health – fluoride has improved oral health Family and social functioning:
  • Parents and carers – parenting has a profound and lasting impact on health, development and wellbeing
  • Mental health – affects 1 in 5 children and young people
  • Child abuse and neglect – the tip of the iceberg Services in children’s health care:
  • Early childhood health services
  • Family carer centers
  • Residential family care services
  • Child and family teams
  • Child protection services
  • Hospital services
  • Children’s units in general hospitals
  • Children’s hospitals
  • Outreach programmes. Puberty:
  • Young people become physically mature and capable of reproduction
  • Girls average is a two year lead on boys
  • BMI is one of the strongest indicators of timing of girls puberty
  • Female puberty usually takes 2-4 years to complete in the following sequence’ budding of breasts, growth spurt, menarche – first

menstruation, appearance of underarm and pubic hair and completion of breast development

  • The first sign of male puberty is the enlargement of the testes and changes in the texture and colour of the scrotum
  • Emergency of pubic hair and enlargement of penis
  • Soon after underarm air appears
  • Spermache usually occurs @ 13 years of age
  • Many boys have an initial period of reduced fertility
  • Facial body hair come later with the process of continuing slowly
  • Deepening of the voice GIRLS
  • Menarche occurs after the peak of the height spurt that is once girls have nearly reached their mature body size
  • The sequences have clear adaptive value – menstruation is delayed until the girls’ body is large enough for successful childbearing. Prevention of pregnancy and STI’s:
  • Adolescent decision making about intercourse with ot without protection is complex, factors include;
  • Socioeconomic conditions
  • Psychological factors
  • Race
  • Peer relationships
  • Family values
  • Accurate knowledge of sex and sexual health can be challenging for adolescents
  • Sex education
  • Mothers are usually more effective communicators than fathers
  • Daughters receive more information than sons
  • Parents who do discuss sexuality openly with their children may reduce their risk of STD’s or unwanted pregnancy Contraception and STI’s:
  • Condoms
  • Low dose contraceptive pill
  • Prevention of STI’s is abstinence Pregnancy
  • Major physiological changes
  • Process of 206 days (38 weeks) from time of fertilization
  • Changes to all the maternal body systems that are controlled by hormones; human chronic gonadatrophin (HCG), human placental lactogen (HPL), oestrogens and progesterone.
  • Obvious changes are in the reproductive system; enlargement of uterus, softening of the cervix, enlargement of the vulva, growth and development of breasts
  • Hematological system
  • CV system
  • Respiratory system
  • GI system
  • Integumentary – gums. Routine blood screening:
  • Blood group and determination of rhesus factor
  • Full blood count
  • STI’s
  • Hep B
  • Rubella antibodies
  • HIV
  • Gestational diabetes
  • Down syndrome and other conditions (1st^ trimester maternal serum screening in combination with scan or 2 nd^ semester maternal serum screening) What complications are involved with pregnancy?
  • Bleeding
  • Spontaneous abortion – abnormal chromosomal complement, uterine or cervical abnormalities, maternal systemic illness, infection
  • Ectopic pregnancy – incidence of ectopic pregnancy increases, adolescents have the higher rate of mortality.
  • History of pelvic inflammatory disease (PID)
  • Use of intrauterine device (IVD)
  • History of pelvic surgery (previous ectopic pregnancy) Medications in pregnancy:
  • Drug use in pregnancy should be restricted according to necessity
  • First trimester of pregnancy is the critical period for teratogenic effects
  • Folic acid recommended to reduce neural tube defects – 0.5 mg of folic acid/day beginning one month prior to conception until 12 weeks gestation.
  • Iron supplements are often recommended What drugs are commonly administered in labour?
  • Synthetic oxytocin – induction of labour
  • Prostagalndins – cervical gel – ripening of softening of the cervix
  • Nitrous oxide – laughing gas
  • Pethidine – opiate antagonist naloxone or narcan
  • Epidural analgesia – wide variety of anaesthetic agents and doses
  • Lignocaine hydrochloride – with forceps or for suturing of the perineum Adolescent prenatal care:
  • Unaware of pregnancy
  • Denial
  • Lack of understanding of the benefits of care Mothers and unborn infants are therefore at greater risk for complications in pregnancy and birth such as;
  • Premature labour
  • Low birth weight and infants
  • High neonatal morbidity
  • Infection
  • Miscarriages
  • Palpitation
  • Iron deficiency anaemia
  • Cephalopelvic disproportion (cpd)
  • Collect history of parents
  • Genetic factors
  • Home assessment – other children they’ll be living with
  • Physical mental health history
  • Past history or problems with pregnancy

Perinatal mental health: Psychiatric diagnoses are 4 times greater in the perinatal period possibly due to

  • Grief
  • Adjustment disorder
  • Anxiety
  • Mood disorder
  • Personality disorder
  • Psychosis
  • Substance related Tocophobia: is the fear of pregnancy or childbirth. Predisposing factors include;
  • Sexual abuse
  • Termination of pregnancy
  • Instrumental/operative birth
  • Foetal distress/severe pain
  • Perineal tearing □ Consequences of having this can result in termination of pregnancy, sterilization. □ Is to be assessed with hyperemesis gravidorum and depression, PND/AND and PTSD. How do we predict postnatal depression?
  • Screen in pregnancy
  • 30-40% of women with PND display symptoms in pregnancy
  • Routine screening – EPNDS (Edinburgh post natal depression scale)
  • Level of placental CRH (corticotrophin-releasing hormone @ 20 weeks gestation may help predict postnatal depression
  • Assess for non-biological risk factors and explore possible interventions
  • Low self-esteem, antenatal anxiety, low social support, negative cognitive style, major life events, low income, history of abuse etc. MANAGEMENT STRATEGIES
  1. Psychological therapy and support
  2. Pharmacology
  3. Social support
  4. Complementary therapy PSYCHOLOGICAL THERAPY AND SUPPORT
  • Psychotherapy
  • Information support
  • Debriefing
  • Home visits PHARMACOLO GY
  • SSRI
  • Tricyclic
  • Family
  • Friends
  • Support groups
  • Indigenous support workers COMPLEMENTARY THERAPY
  • Infant massage, benefits all members of the family, including fathers
  • Exercise (to improve mood)
  • Distraction techniques What are the effects of maternal depression on a child? INFANTS
  • Passivity
  • Anger
  • Low weight gain
  • Insecure attachment
  • Attention and arousal problems TODDLERS
  • Passive noncompliance
  • Less independence
  • Lower performance
  • Less interaction with others on verbal and memory tests
  • Less creative play CHILDREN School Age:
  • Impaired adaptive functioning
  • Depressive disorders
  • Anxiety disorders
  • Attention disorders
  • Lower IQ Adolescents:
  • Depressive disorder
  • Anxiety disorder
  • Substance abuse
  • Conduct disorder
  • Attention disorders
  • Learning difficulties What mental health disorders are experienced in infancy?
  • Feeding and eating disorders
  • Pervasive developmental disorders
  • Relationship problems or attachment disorders
  • Anxiety disorders or separation anxiety
  • Motor skills disorder What mental health disorders are experienced in childhood? Internalizing behaviour:
  • Mood
  • Sleep
  • Thoughts
  • Parents often report ‘something is not

quite right’ Externalizing behaviour:

  • Aggressive and delinquent behaviours
  • Children’s bones are more easily damaged than an adult e.gh by twisting, minor falls
  • Less bony so less force is required to cause fracture
  • Active mobility and lack of coordination contribute to frequency of fractures in children
  • Fractures are less likely to be accompanied by self tissue damage
  • They are not so obvious Treatment for fractures:
  • Alignment depends on age; distance of the fracture from the end of the bone, the amount of angulation, the younger the child and the closer to the epiphyseal plate the greater the chance of deformity
  • Anatomic reduction
  • Maintenance of reduction until complete healing
  • Minimization of complications associated with the injury
  • And its treatment
  • The most important factors determining the outcome of treatment in these injuries as follows; age of the child, type of fracture, degree of displacement of the fracture fragments and length of time since injury
  • Closed manipulation/reduction, plaster immobilization
  • May need operating theatre for light anaesthetic
  • Muscle relaxant – to reduce muscle spasms which is more cause of pain Note: children put things down their casts and fear the plaster cutter on removal. What are the different types of fractures?
  • Open and closed
  • Greenstick
  • Spiral
  • Comminuted
  • Transverse
  • Compound
  • Vertebral compression What tool classifies fractures? Salter-Hams. What is the weakest area in fractures? Growth plates in long bones Weaker than supporting ligaments Forces that would cause a sprain in an adult may cause a fracture in children Fractures can occur across physes (growth plate) epiphyses and metaphyses growth implications What are the problems with X-rays finding children fractures?
  • Children’s fractures do not always show on x-rays as they have more cartilage than bone and sometimes an angulation shows.
  • A diagnosis is made on history and clinical sighs for e.g. point tenderness and deformity aswell as an understanding of typical fractures in children
  • The x ray will show as healing occurs and callous forms in 3- weeks.
  • X-ray showing fractures at various stages of healing, periosteal bleeding in long bones, usually caused by rough handling, twisting and pulling of limbs
  • No explanation or hospital visit for injury, yet evidence on xray 3-6 weeks after injury
  • When callous has formed/healing occurred explanation of injury does not fit or is inconsistent with clinical picture Toddler fractures:
  • Ligaments are stronger than bones – mostly cartilage and balance on these even with fracture
  • Toddlers are not fully balanced- frequently fall even when running, leg may twist resulting in a fracture, non- displaced spiral fracture
  • Fall may not be witnessed- but child does not want to weight bear
  • Often no external signs and full range of motion- splinting or casting required Fractures in older children:
  • Fractures forearm – from extending hand to break a fall e.g. skateboard, roller skates, running
  • Humerus and clavicle fractures from transmitted pressure/force up arm
  • Falls from heights – trees, roofs, playground equipment, car and bicycle accidents and may result in lower limb fractures
  • Femoral shaft fractures Compartment syndrome: Compartments are anatomical groups of muscle, nerve and blood vessels confined with inelastic boundaries such as muscle, skin bone and especially fascia. Intra-compartmental pressure can be raised by; 1.Increase in compartment content (bleeding, swelling) 2.Decreasing in size of compartment bleeding or pressure from another area into the compartment surrounds, including pressure from bandages plaster pressure results in severely decreased blood flow that potentially threatens damage to and necrosis of surrounding soft tissue or renes if oedema and further increase in pressure a fasciotomy may be necessary to prevent further damage. Who is at risk of compartment syndrome?
  • Children who have had open fractures
  • Crush injuries
  • Vascular problems
  • Burns
  • Patients with altered pain perceptions 5 P’s:
  1. Pain
  1. Passive motion
  2. Paralysis – lack of ability to flex or extend toes or fingers
  3. Paraesthesia – numbness or tingling
  4. Pallor – indicating coldness. Pulselessness is considered a late/unreliable sign – the damage is already done Signs and symptoms of compartment syndrome:

capacity to metabolize drugs in early infancy, then enhanced metabolism in late infancy toddlerhood. May need higher doses of pain medications but less frequent doses and may have greater effects of some drugs.

  • Hepatic toxicity – Paracetamol metabolism via a major pathway in liver. Depends on sufficient liver enzymes to bind up the metabolites so they can be excreted in urine. Otherwise minor pathway is used and can result in build up of toxic metabolites.
  • Young children have less hepatic enzymes so dosage is extremely important with Paracetamol, amount given in any 24 hour period is important. Pain Management: - IV route for pain is the best practice for hospital situation - Infusions are well tolerated - Monitoring important and PCA - Nurse controlled analgesia - Regular pain assessment - Use of non-pharmacologic strategies Routes of administration in children:
