Answer and Explanation

A.   At 12 months, the infant walks independently: Most infants begin walking independently between 12 and 15 months of age, but it's not typically achieved by 12 months.

C.   At 9 months, the infant crawls with the abdomen off the floor: Crawling typically begins between 7 and 10 months, but the abdomen may still be close to the floor initially.
D.   At 1 month, the infant lifts and turns the head to the side in the prone position: This is an accurate statement. Newborns typically exhibit head control and turning movements when placed on their stomachs (prone position) by around 1 month of age.

E. At 2 months, the infant rolls from supine to prone to back again: Rolling from supine to prone and back may begin around 4 to 6 months, but it's less likely to occur at 2 months.

Correct Answer is B

Explanation

A. Has a fear of strangers: Fear of strangers typically emerges around 6 to 9 months of age as part of normal social development. While it indicates cognitive and emotional growth, it does not necessarily warrant further evaluation unless it is excessive or accompanied by other concerning behaviors.

B. Uses a unidextrous grasp: By 7 months, infants typically develop a more refined pincer grasp, where they can pick up small objects using the thumb and forefinger (bidextrous grasp). A unidextrous grasp (using only one hand) may suggest a delay in fine motor development and could warrant further evaluation by a healthcare provider.

C. Babbles one-syllable sounds: Babbling is a typical milestone in language development for

infants around 6 to 9 months of age. One-syllable babbling is expected at this stage and does not necessarily indicate a need for further evaluation.

D. Shows preferences towards foods: Developing food preferences is part of normal feeding behavior for infants. While it is important to ensure a balanced diet, showing preferences towards certain foods is not typically a cause for concern at this age.

A. Absorption of drugs administered by subcutaneous injection is increased. B. Absorption of intramuscularly administered drugs is fairly constant. C. Topical drugs are absorbed more quickly in young children than adults. D. Oral drugs are absorbed more quickly in children than adults.

Correct Answer is B

Explanation

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.
