When describing the differences affecting the pharmacokinetics of drugs administered to children, which would the nurse include?

Absorption of drugs administered by subcutaneous injection is increased.

Absorption of intramuscularly administered drugs is fairly constant.

Topical drugs are absorbed more quickly in young children than adults.

Oral drugs are absorbed more quickly in children than adults.

Answer and Explanation

The Correct Answer is B

A. Absorption of drugs administered by subcutaneous injection is increaseD. Subcutaneous absorption can vary based on factors such as blood flow and tissue characteristics, but it is generally slower and more variable compared to intramuscular absorption.

B. Absorption of intramuscularly administered drugs is fairly constant: Intramuscular absorption tends to be more consistent compared to subcutaneous absorption. However, absorption rates can still be affected by factors such as muscle mass and blood flow.

C. Topical drugs are absorbed more quickly in young children than adults: Topical drug absorption can be influenced by factors such as skin thickness and permeability, but absorption rates may not necessarily be faster in young children compared to adults.

D. Oral drugs are absorbed more quickly in children than adults: This statement is generally incorrect. While gastrointestinal transit time may be faster in children, other factors such as

gastric pH and enzymatic activity can affect oral drug absorption, and absorption rates may not always be faster in children compared to adults.

Correct Answer is A

Explanation

A. An infant's rate is 90 bpm.

An infant's normal heart rate typically ranges from 70 to 150

B. A toddler's rate is 150 bpm.

The normal heart rate for a toddler usually ranges from 70 to 130. Therefore a rate of 150 bpm would be considered tachycardia in a toddler.

C. A preschooler's rate is 130 bpm.

The normal heart rate for a preschooler typically ranges from 80 to 120 bpm, with an average rate around 100-110 bpm. A rate of 130 bpm would be considered tachycardia in a preschooler.

D. A school-age child's rate is 50 bpm.

The normal heart rate for a school-age child usually ranges from 75 to 118 bpm. A rate of 50 bpm would be considered bradycardia in a school-age child.

A. A premature newborn B. A postterm newborn C. A newborn born to a diabetic mother D. A term newborn with jaundice

Correct Answer is A

Explanation

A. A premature newborn: Premature infants are at higher risk for iron deficiency anemia because they have lower iron stores at birth compared to full-term infants. Additionally, premature infants may not have had sufficient time in utero to accumulate adequate iron stores from maternal

transfusions.

B. A postterm newborn: Postterm infants, born after 42 weeks of gestation, are not typically at increased risk for iron deficiency anemia solely based on gestational age.

C. A newborn born to a diabetic mother: While infants born to diabetic mothers may have other health risks, they are not inherently at higher risk for iron deficiency anemia unless there are other complicating factors such as prematurity or inadequate iron intake.

D. A term newborn with jaundicE. Jaundice in a term newborn is typically caused by elevated

levels of bilirubin and is not directly associated with an increased risk of iron deficiency anemia.
