A

used to administer meds infused over intermediate timeframes

53
Q

what is the typical volume of IVPB

A

50-250mLs

54
Q

what is the timeframe the IVPB is infused

A

usually over 15-60minutes

vancomycin minimum infusion is 60min

55
Q

what do you need to assess when hanging IVPB

A
  • why pt is receiving med
  • pertinent labs
  • adverse effects of the med
  • contraindications
  • interactions w/other meds
  • nsg implications
  • compatibilities with other meds/fluids
  • Rate for administration

  • verify safe strength
  • pt education
56
Q

what should you teach the pt about the IVPB

A
  • name of med and why they are receiving it
  • adverse effects
  • s/s of infiltration
57
Q

what are the advantages of IVPB

A
  • rapid onset of action
  • predictable therapeutic levels can be achieved
  • can give larger doses than IM
  • Can rapidly terminate drug admin if necessary
  • can use for meds that can’t be administered other routes
58
Q

what are disadvantages of IVPB

A
  • expensive
  • keeping IV site patent
  • increases risk of adverse reactions- speed shock extravasation, phlebitis
59
Q

what is speed shock

A

headache, chest tightness, shock, cardiac arrest

all caused from too rapid administration

60
Q

what are safety measures for implementation of IVPB

A
  • check label on IVPB
  • the rate is safe
  • the concentration is safe
  • the dose is safe
  • compatibilities of solution
  • checking for allergies
61
Q

where do you hook up the IVPB

A

above the pump so the pump can control the rate

if you hook it up below the pump, the roller clamp is the only thing regulating the flow

62
Q

why do you want to hang the primary IV solution lower than the IVPB

A

because the pump pulls from what has the most pressure (gravity) so the IVPB that is higher will cause more pressure and the pump will pull from that first

63
Q

what does the back check valve do

A

prevents secondary med from going back into the primary IV bag

64
Q

what do you do with IVPB tubing that is already used when you need to hang a 2nd IVPB

A

when the IVPB is empty and you are changing the IVPB bag:

  • pause the pump
  • do not administer med in the line to the pt
  • make sure new IVPB is compatible with old
  • lower old IVPB lower than the pump to prime the line
  • take old bag off, spike new bag and hang it up(with clamp on)
  • unclamp
  • on pump-click 2ndary-go to library and click med
  • make sure rate and infusion is safe
  • click start
65
Q

what are the 2 things you want to check before leaving the pt after hanging IVPB

A
  • make sure you see drip from correct bag

- check IV site to make sure its not leaking, hurting, etc

66
Q

how frequently do you change the line

A

q3-4days

depending on facility policy

67
Q

how do you set up a new IVPB with new tubing

A
  • get your new tubing and IVPB
  • close clamp
  • lower primary IV
  • spike IVPB
  • alcohol Y site on primary IV
  • connect tubing
  • pause infusion
  • lower IVPB and prime new tubing
  • Hang IVPB higher than primary
  • program pump for 2ndary IV rate, volume,
  • start infusion
68
Q

what is back flush

A

flushing the IVPB line back into the IVPB bag. its used to prime the line with primary IV solution when switching the IVPB bags

69
Q

what do you need to do when administering IVPB via saline lock

A

flush with saline first
then administer med
then flush with saline after med admin is complete

70
Q

how do you do IVPB via saline lock

A
  • need primary solution (NS) aka flush bag
  • prime primary tubing
  • connect to pt
  • set primary rate the same as the IVPB
  • program primary flush to infuse 2x the mL amount of IV tubing
  • open 2ndary tubing, close clamp
  • lower primary bag
  • spike IVPB
  • alcohol swab Y site
  • prime 2ndary line
  • hang IVPB higher than primary
  • program pump for IVPB
  • start infusion
71
Q

how do you manage incompatibility between IVPB

A

back flush the secondary tubing into the OLD IVPB bag 3 TIMES

72
Q

how long are IV bags usually good for

A

24 hours

73
Q

should you use IV tubing if it is having over the pump plugged into the lower port

A

Not usually. the sterility is not guaranteed

74
Q

what do you do if the IVPB never infused

A

notify the MD.

it is a missed dose and a medication error so it needs to be reported.

75
Q

if you have 2 IVPBs to administer at the same time how do you know what to infuse first

A
  • if one is an abx that has to be on a specific schedule, you would want to do that first to keep the time right.
  • if you have one that is QD or Q6hours, you may do that 2nd b/c you still have the 30 minute window
  • you would want to hang the one that has smaller amount or shorter infusion time first
76
Q

If the IV site is burning to the pt what could be causing this

A
  • check the catheter and IV site to make sure it looks ok
  • could be an irritant in the medication
  • K+ can cause pain
77
Q

If the pt complains of burning what can you do to relieve it

A

slow the IV rate
warm compress on the arm
explain to pt that (if it is the med) that is normal with that medication and try to relieve burning

78
Q

when using the syringe pump for IVPB where do you hook up the tubing to on the primary IV

A

hook in to the lower Y site on the primary tubing (below the pump) because the syringe pump is controlling the rate of infusion

79
Q

how do you prime the 2ndary tubing when using a syringe pump

A

you would have to prime it with the medication you are giving

80
Q

routes of heparin

A

can be given subQ and IV

81
Q

what route do you never want to give heparin

A

intramuscular because it will cause hematomas

82
Q

what do you do if you already have a primary IV solution going and need to start a Heparin infusion

A

you need to have its own IV tubing and pump.
it has to be run as a primary IV line. NOT as an IVPB.
once you set up its own pump you can attach it to the Y site BELOW the primary solution pump

83
Q

what % of water are children

A

70%
which means the child can be easily depleted of water leading to dehydration, electrolyte imbalance and vascular collapse

84
Q 
what is the normal HR and respiration's in a 
full term newborn
infant
toddler
school age/adolescent
A

Full term: HR 100-160(higher in preterm) RR: 30-60
Infant: HR 80-120 RR 30-60
toddler: HR 70-100 RR 24-40
school age/adolescent: HR 60-100 RR 15-26

85
Q

what is an appropriate O2 sat on a child

A

95% or above.

anything lower indicates decreased oxygenation of tissue.

86
Q

why can a pulse ox give you a false high reading

A

because the pulse ox reads the amount of hgb that is saturated with o2 therefore a pt with anemia can have a false high because it takes less oxygen to saturate hgb.

87
Q

what are important indicators of sepsis in a newborn or young infant

A

a subnormal body or elevated temp and poor feeding

88
Q

when can you perform a temporal temperature on a child

A

after 90 days.

prior to that the methods are either rectal or axillary

89
Q

what can cause a very high HR in a child

A

fever, anxiety, medications, dysrhythmias

90
Q

what can cause a slow HR

A

dysrhythmias, cold submersion, Digoxin toxicity

91
Q

why do infants have a low BP

A

because they have very little peripheral vascular resistance

92
Q

what head circumference should be in relation to chest circumference in
a newborn
a 1-2 yr old
older child

A

newborn: HC should exceed the chest circumference by 2-3 cm

a 1-2 yr old: HC should equal chest circumference

older child: chest circumference exceeds HC by 5-7cm

93
Q

what does it indicate if the HC is less than the 5th percentile or greater than the 95th percentile

A

if its less than it can indicate lack of expected brain growth
if greater than it can indicate hydrocephaly or increased intracranial pressure

94
Q

up until what age do we measure head circumference

A

birth to 36 months (3 yrs)

95
Q

what should the head circumference be in boys

A

from 32 to 37cm at birth to 46-51cm at 24 months

96
Q

what should the head circumference be in girls

A

from 32-36cm at birth to 45-50cm at 24 months

97
Q

along with the systems assessment what other assessment should we perform

A 
psychosocial
developmental level
sleep/rest
safety
appetite/nutrition
accurate weight
98
Q

what does it mean if the fontanels are bulging or sunken in

A

if they are bulging it indicates increased intracranial pressure or fluid excess (however bulging when crying is normal)
if they are sunken in it indicates a fluid deficit

99
Q

what is congenital dermal melanocytosis

A

bluish spots on the lower back/buttock region

usually seen on east asian and dark skinned infants

100
Q

what is a hemangioma

A

a benign tumor usually appearing as a bright red rubbery nodule of excess blood vessels in the skin.
occurs in small % of infants and most disappear. usually resolves by age 10-12

101
Q

why are infants more prone to respiratory problems

A

because they have smaller, narrow, shorter trachea and bronchi which are more easily collapsable or being obstructed.
it is a shorter distance for pathogens to travel
and its difficult to isolate adventitious lung sounds because they are so small

102
Q

what are some abnormal respiratory assessment findings

A 
cough
hoarsness
nasal flaring
diminished breath sounds
adventitious breath sounds
sternal retractions
circumoral cyanosis -cyanosis of lips
103
Q

what needs to be verified prior to adding K+ to IV fluids

A

the presence or renal function has to be established because in children who have a condition that might predispose to renal failure such as dehydration, there can be a build up of K+ in the body if the renal system is not functioning properly

104
Q

what is the normal urine output in pediatric patients

A

0.5-2mL/kg/hr

105
Q

what are acute signs of neonatal pain

A

facial expressions, diaphoretic, guarding, change in sleeping and eating habits
changes in vitals- increased HR and respirations

106
Q

what scale do you use to assess neonatal pain

A

NIPS-neonatal infant pain scale
it assesses facial expression, cry, breathing, arms, legs and alertness
maximum score is seven points- consider pain at or greater than 4

107
Q

why would you distract a toddler when doing a painful procedure.

A

they can’t focus on multiple things. The distraction works like imagery in the sense that it diverts pain signals and the pleasure signals then become faster than the pain signals

108
Q

what is the FLACC pain scale

A

face, legs, activity cry consolability

used for 3mo-7yrs

109
Q

what is acrocyanosis

A

blueness of the hands and feet in babies that can last up to several days of age resulting from immature circulatory system completing the switch from fetal to extrauterine life.
