transit time and variable gastric pH
2) Frequent feeding may impede drug absorption
3) Low levels of intestinal flora and reduced enzyme function can lead
to decreased absorption
4) Low peripheral perfusion and immature heat regulation can decrease
absorption of IV, IM, or SC medications
,By what age in children is gastric pH equal to adult gastric pH? - Precise
Answer ✔✔Age 2-3 years
Distribution in infants is increased due to: - Precise Answer ✔✔1) Low
concentration of plasma proteins and diminished protein binding
capacity allow drugs to be more available in the circulation
2) Greater permeability of the blood-brain barrier allows for rapid access
of drugs to the CNS.
3) Total body water is 80% compared to the adults 50%.
By what age to plasma proteins reach adult levels? - Precise Answer

✔✔1) Drug-metabolizing enzymes in the liver of infants are immature
2) More drugs in the circulatory system due to ow concentration of
plasma proteins and diminished protein binding. This may increase the
potential for drug toxicity
Excretion in infants is less effective than adults due to: - Precise Answer
✔✔1) Infant kidneys have higher resistance to blood flow and lower
GFR with a decreased ability to concentrate urine.
, 2). Infants may secrete drugs more slowly, increasing the risk of drug
accumulation.
By what age are children able to excrete drugs more effectively? -
Precise Answer ✔✔>12 months
Steps for pediatric medication calculations: - Precise Answer ✔✔1)
Convert pounds to kilograms by dividing the weight in pounds by 2.2.
Dosage recommendations will be mg/kg. 2.2 lbs= 1 kg
2) Calculate the dose in mg.
(dose in mg) x (how much the patient weights in kg) = dose
3) Divide the dose by frequency.
(dose in mg) ÷ (times per day they should take medication) = ____ mg
per dose
4) Convert the mg dose to mL (for liquid preparation). Divide the dose
by medicine concentration to obtain the liquid dose.
(mg per dose) ÷ (mg of concentration x mL per concentration) = ____
mL per dose.
