11th Hr Review Flashcards
What is the formula to know the normal BP in a child?
- Systolic = 90 + 2 times age in years
- Diastolic = 2/3 (.66%) of systolic
What is the formula to figure out the lower limit of BP systolic reading?
70 + 2 times age in years
What is the formula related to fever and fluid requirements?
for every degree over 100.4 add 10-15% to hourly total
What is the formula to determine acceptable urine output for the pediatric patient?
1-2 mL/kg/ hour
If your patient weighs 17kg and has a urine output for the past 24 hours of 256 mL, what does that indicate?
- 17*24= 408 (minimum amount pt should have eliminated)
- 256 mL is well below the minimum
What is the formula for IV fluids for fluid restoration?
20mL/kg bolus NS over 20-30 mins
What is the formula for fluid IP total when treating dehydration?
Fluid IP total = rehydration therapy + maintenance therapy
What is the formula for calculating how many calories per day a 0-6mos old infant will need to maintain minimum proper growth and how do you calculate the oz of formula required to fullfill it?
- 108*kg = Total calories/day
- Total calories / 20 = oz of formula/day
How many calories will a 12kg 3mos old infant require per day and how many oz of formula will be needed meet the requirement?
- 12*108 = 1,296 calories/day
- 1296/20 = 64.8 oz of formula/day
What are the caloric densities of the following:
- Breast milk
- Regular formula
- High calorie formula
- Breast milk = 20cal/oz
- Regular formula = 20cal/oz
- High calorie formula = 22-24cal/oz
What is the formula to calculate fluid maintenance requirements for children?
- First 10kg = 100 mL/kg
- Second 10kg = 50 mL/kg
- Over 20 kg = 20 mL/kg
What are the daily and hourly fluid maintenance levels for a child weighing 22kg?
- First 10kg = 100 mL*10 = 1000mL
- Second 10kg = 50 mL*10 = 500mL
- Extra 2 over 20 = 20 mL*2 = 40mL
- 1000+500+40=1540 mL
- Per hour = 1540/24=64 mL/hr
What is the maintenance fluid rate for Sickle Cell Anemia Crisis?
Calculate as normal and multiply by 1.5 (x2 is also acceptable).
How long should the PR interval be?
- 0.12-0.20 or
- 3-5 small squares
How long should the QRS interval be?
0.06-0.12 or
< than 3 small squares
How do you calculate the HR w/ a 6 second strip?
- # of R waves in 6 seconds x10
- Rhythm must be regular
How do you calculate an irregular rhythm on a strip?
300 divided by the number of boxes between R waves
-LOL
Name: Class, What it does, and memory analogy
- Beta Blocker
- Blocks beta 1 receptor which
- Decreases HR, CO, BP
- Analogy: LOL because Beta blockers are on all the tests
-PINE
Name: Class, What it does, and memory analogy
- Calcium Channel Blocker
- Blocks calcium channels which
- Reduces contractility
- Analogy: Pine tree blocking a river of calcium
-PRIL
Name: Class, What it does, and memory analogy
- ACE Inhibitor
- Prevent conversion of Angiotensin 1 into Angiotensin 2
- Angiotensin 2 is a potent vasoconstrictor
- Analogy: Pril = Prick = Douche who is preventing us from being an ACE in class
-SARTAN
Name: Class, What it does, and memory analogy
- Angiotensin Receptor Blocker (ARB)
- Blocks angiotensin receptors thus not allowing vasoconstriction
- Analogy: SARTAN to SATAN = SIN (angiontenSIN) = Angiotensin Receptor Blocker
-STATIN
What do drugs that end with “STATIN” do?
- Lowers LDL production
What are PTU & Methimazole and what do they do?
- Antithyroid agents
- Correct a hyperthyroid state by blocking thyroid hormones
What does Radioactive Iodine do?
- Shrinks hyperfunctioning thyroid nodules
- Corrects hyperthroid state
