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. Describing the tongue extrusion reflex: The tongue extrusion reflex is typically present in
infants up to around 4 to 6 months of age and diminishes as they begin to eat solid foods. At 7 months, this reflex is likely no longer prominent.
B. Explaining how to prepare table meats: While introducing solid foods is important around 6 months of age, meats are often introduced later in infancy due to their texture and potential
allergenicity. At 7 months, infants may still be primarily consuming pureed or mashed foods.
C. Advising about increased caloric needs: At 7 months, infants are transitioning to a more varied diet that includes solid foods alongside breast milk or formula. Guidance on meeting their
increasing nutritional needs is crucial at this stage.
D. Discussing the type of sippy cup to usE. Sippy cups are typically introduced closer to the end of the first year or during the transition to weaning from the bottle. While it's important to
discuss appropriate feeding utensils, addressing increased caloric needs is a more immediate concern for a 7-month-old infant.
Correct Answer is B
Explanation
A. At 6 years, children are expected to have mastered the ability to descend stairs without needing to place both feet on each step or hold onto the railing.
B. By 3 years of age, children typically begin to walk up stairs using a reciprocal pattern, placing only one foot on each step, but may still require a railing for support when going down.
C. At 4 years, children should be able to go both up and down stairs using a reciprocal pattern and without the need for a rail.
D. By 5 years, the expectation is that children can confidently navigate stairs in a manner similar to adults, without placing both feet on each step or requiring railing support.
