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 D
Explanation
A. "I can fit my hand between the baby and the car seat harness."
This statement indicates that the harness may not be properly snug against the infant's body, which could compromise safety.
B. "Our car seat is front-facing in the back seat."
For a 6-month-old infant, the car seat should be rear-facing to provide optimal safety in the event of a crash. Front-facing seats are typically used for older children.
C. "The car seat is rear-facing in the front passenger seat."
Rear-facing car seats should never be placed in the front passenger seat, especially if the car is equipped with airbags. The back seat is the safest location for a car seat.
D. "Our car seat is an infant model and is anchored in the car."
This statement indicates that the parent understands the importance of using an appropriate car seat for the infant's age and size and that the seat is properly installed and secured in the vehicle.
Correct Answer is D
Explanation
A. TympaniC. Tympanic temperature measurement using an ear thermometer is a convenient and accurate method for assessing temperature in children, including toddlers.
B. Oral: Oral temperature measurement using a digital thermometer placed under the tongue is a commonly used method for children who can cooperate with the procedure and keep the
thermometer in their mouth.
C. Axillary: Axillary temperature measurement using a thermometer placed in the armpit is a non-invasive method suitable for children who cannot cooperate with oral or tympanic
measurements or when rectal measurement is contraindicated.
D. Rectal: Rectal temperature measurement is generally considered the most accurate method for assessing temperature in infants and young children, especially when accuracy is critical.
However, it may be less appropriate in the emergency department setting due to its invasive nature and potential discomfort for the child, especially in cases of diarrhea or vomiting where rectal temperature measurement may be difficult or impractical.
