Which statement best describes why infants are at greater risk for dehydration than older children?

When the skin surface is caked with desquamated skin and sebaceous secretions after the removal of a cast, the nurse should suggest washing the area with warm water and soap. This will help to gently cleanse the skin and remove the accumulated material without causing unnecessary trauma or irritation.

Option A, applying powder to absorb the material, may not effectively remove the caked material and could potentially lead to further clumping or discomfort.

Option B, vigorously scrubbing the leg, can be harsh on the skin and may cause skin irritation, redness, or even abrasions. It is important to be gentle and avoid excessive scrubbing, especially on the fragile and recently exposed skin.

Option C, carefully picking the material off the leg, can increase the risk of skin injury or introduce bacteria into the skin. Picking at the skin should be avoided to prevent further damage or infection.

Therefore, option D, washing the area with warm water and soap, is the most appropriate and gentle method to remove the caked material from the skin surface

The first sign of pubertal change seen with boys is testicular enlargement. This is known as testicular or scrotal growth and is one of the earliest physical signs of puberty in boys. Testicular enlargement is followed by other changes such as the growth of pubic hair, penile growth, voice deepening, and facial hair growth.

voice deepening in (option A) is incorrect because it, typically occurs after testicular enlargement and is associated with the growth and development of the larynx during puberty.

scrotal enlargement in (option B) is incorrect because it, may occur simultaneously or shortly after testicular enlargement as part of overall genital growth during puberty.

, facial hair growth in (option C) is incorrect because it, is a later sign of pubertal development in boys and typically occurs after the initial testicular enlargement and growth of pubic hair.
