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.
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 C
Explanation
A. Carotid artery: The carotid artery is not typically used to assess heart rate in infants due to its location and difficulty in palpation.
B. Radial artery: The radial artery is not typically used to assess heart rate in infants, especially in non-cooperative or newborn infants.
C. Apex of the heart: Assessing the heart rate by auscultating the apex of the heart with a stethoscope is the most accurate method for infants.
D. Brachial artery: The brachial artery is not typically used to assess heart rate in infants. It is commonly used to measure blood pressure.
Correct Answer is B,E,C,A,D
Explanation
B. Trust vs. mistrust: This is the first stage, occurring from birth to approximately 18 months of age, where infants learn to trust or mistrust their caregivers and the world based on
whether or not their basic needs—such as food, affection, and safety—are met.
E. Autonomy vs. shame and doubt: The second stage, from roughly 18 months to 3 years, is when toddlers begin to assert their independence. If caregivers encourage self-sufficient behavior, toddlers learn to be autonomous; if not, they may develop feelings of shame and doubt about their abilities.
C. Initiative vs. guilt: During the preschool years, from about 3 to 6 years, children begin to assert power and control over their world through directing play and other social interactions.
Successful completion of this stage leads to a sense of initiative, while failure results in feelings of guilt.
A. Industry vs. inferiority: Occurring from age 6 to puberty, this stage is characterized by the child's navigation of social demands and learning to develop a sense of pride in their accomplishments and abilities. If this stage is managed well, the child will feel industrious; if not, they may feel inferior.
D. Identity vs. role confusion: The final stage in Erikson's model for adolescence, from puberty to young adulthood, involves developing a sense of self and personal identity. Success leads to an ability to stay true to oneself, while failure leads to role confusion and a weak sense of self.
