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 B

Explanation

A. Inspection, percussion, palpation, auscultation: This sequence starts with visual inspection, followed by percussion (tapping the body to assess underlying structures), palpation (using the hands to feel for abnormalities), and finally auscultation (listening with a stethoscope to assess sounds such as heart, lung, or bowel sounds). However, palpation is usually performed before percussion.

B. Inspection, palpation, percussion, auscultation: This is the correct sequence for performing a physical examination. It begins with visual inspection, followed by palpation to assess for

tenderness, masses, or other abnormalities, then percussion to evaluate the density of underlying structures, and finally auscultation to listen to internal sounds.

C. Palpation, percussion, inspection, auscultation: This sequence starts with palpation, followed by percussion, then inspection, and finally auscultation. However, inspection is typically performed before palpation in a physical examination.

D. Inspection, auscultation, palpation, percussion: This sequence starts with visual inspection, followed by auscultation, palpation, and percussion. While auscultation often follows inspection, palpation is usually performed before auscultation.

A. "I will give him a pacifier during feeding time." B. "We need to make sure he doesn't lose the desire to eat by mouth." C. "We need to keep feeding time very quiet." D. "Sucking produces saliva, which aids in digestion."

Correct Answer is A

Explanation

A. "I will give him a pacifier during feeding time.": Giving a pacifier during feeding time may interfere with the infant's ability to coordinate sucking, swallowing, and breathing, especially if

they are receiving nutrition through a nasogastric tube. This response indicates a need for further teaching because pacifiers during feeding time could potentially disrupt the infant's feeding

pattern and may not be appropriate in this situation.

B. "We need to make sure he doesn't lose the desire to eat by mouth.": This response

demonstrates an understanding of the importance of maintaining the infant's oral feeding skills and indicates appropriate knowledge about promoting oral feeding while using a nasogastric

tube.

C. "We need to keep feeding time very quiet.": Keeping feeding time quiet can help reduce distractions and promote a calm environment, which may enhance feeding tolerance for the infant. This response reflects an understanding of strategies to facilitate feeding.

D. "Sucking produces saliva, which aids in digestion.": This response demonstrates knowledge about the benefits of sucking and saliva production during feeding, indicating an understanding of the infant's physiological needs during feeding.
