19
Q

Types of inhaled medication

A

SABA (Salbutamol)
- short acting beta
- beta 2 receptor agonist

LABA (Salmeterol)
- long acting beta
- beta 2 receptor agonist

20
Q

Salbutamol
Drug class
Dose/frequency
Mode of action
Effects

A
  1. Beta 2 receptor antagonist

2.
Asthma - 1-2 (100-200mcg) when required
COPD - 4-8 (400-800mcg) 1-6 hrs
Life threatening - 4 inhalations every 4 minutes. MET if no improvements

  1. Relaxes bronchial smooth muscle and facilitates bronchodilation
  2. tremor, headache
21
Q

Skin - structure and function

A

epidermis, dermis, subcutaneous

  • sensory perception, temperature regulation, absorption and excretion and wound repair
22
Q

SKIN Developmental considerations INFANTS

A

lanugo - fine downy hair
vernix - thick, cheesy substance
sebum - holding water in the skin producing milia

23
Q

SKIN Developmental considerations CHILDREN

A
  • epidermis thickens, darkens and becomes lubricated
  • hair growth accelerates
24
Q

SKIN Developmental considerations ADOLESCENTS

A
  • secretions from apocrine sweat glands increase
  • subcutaneous fat deposits increase
  • secondary sex characteristics
25
Q

SKIN Developmental considerations AGEING ADULT

A
  • loss elasticity (collagen stiffening)
  • sweat and sebaceous glands (decreased extracellular water and surface lipids) dry skin
  • bruise easily
  • Skin breakdown (slower cell replacement - delayed wound healing)
  • decrease functioning melanocytes
26
Q

Skin - subjective data

A
  • change in pigmentation
  • change in mole (size, colour)
  • excessive bruising
  • rash, sores, lesions
  • birthmarks
  • falls (trauma)
27
Q

Skin - objective data

29
Q

Primary Skin Lesions

A

Macule
- flat area with change in skin colour (freckle)

Papule
elevated solid lesion (wart)

Vesicle
superficial collection of serous fluid (varicella)

Plaque

30
Q

Secondary Skin Lesions

A

Fissure
crack/break from epidermis to dermis (corner of mouth)

Scale
dead epidermis from abnormal keratinisation and shedding (flaking skin from sunburn)

Scar
abnormal formation of connective tissue replacing normal skin (healed wound)

Ulcer
loss of epidermis into dermis ; crater and irregular (pressure ulcer)

Atrophy
depression in skin from thinning epidermis/dermis (aged skin)

Excoriation
missing epidermis exposed dermis (abrasion)

31
