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 C

Explanation

A. Forward-facing in the front passenger seat: This position is not suitable for an infant. Infants should always be placed in a rear-facing car seat in the back seat of the vehicle to reduce the risk of injury in the event of a crash.

B. Rear-facing in the back seat next to a window: Placing an infant next to a window increases the risk for injury. The safest position for a car seat is in the center of the back seat

C. Rear-facing in the middle of the back seat: Although the manufacturer of the car seat will provide specifics regarding use, a child should remain in a rear-facing car seat until age 2 or until the child outgrows the height or weight limits of a rear-facing seat

D. Forward-facing in the back seat: Forward-facing car seats are appropriate for older children, typically after they have outgrown rear-facing car seats based on height and weight requirements.

Infants should always ride in a rear-facing car seat until they reach the maximum weight or height limit specified by the car seat manufacturer.

A. Appearance of pubic hair around 11 to 13 years old - Pubic hair development typically occurs around the ages of 11 to 13 in girls, signaling the onset of puberty. This is a normal part of physical development.

B. Swelling or redness of the labia minora - Swelling or redness of the labia minora may indicate inflammation or infection, unrelated to normal puberty development.

C. Lesions on the external genitalia - Lesions on the external genitalia are not normal signs of puberty and may indicate a medical issue requiring evaluation and treatment.

D. Presence of labial adhesions - Labial adhesions, where the labia minora stick together, are not directly related to puberty onset and may require medical attention if they cause discomfort or urinary issues
