What is the most important factor in determining the rate of fluid replacement in the dehydrated child?
The type of dehydration
The child's weight
Urine output
Serum potassium level
The Correct Answer is C
The most important factor in determining the rate of fluid replacement in a dehydrated child
is urine output. Urine output is a crucial indicator of renal perfusion and hydration status.
Monitoring urine output allows healthcare professionals to assess the child's response to fluid
replacement therapy and adjust the rate accordingly.
The type of dehydration in (Option A) is incorrect. The type of dehydration, is important in
determining the appropriate fluid composition for rehydration but does not directly dictate the
rate of fluid replacement.
The child’s weight in (Option B) is incorrect. The child's weight, is considered when
calculating the maintenance fluid requirements, but it does not solely determine the rate of
fluid replacement for dehydration.
Serum potassium level in (Option D) is incorrect. The serum potassium level, is important to
monitor in a dehydrated child, especially in cases of severe dehydration, as electrolyte
imbalances may occur. However, it is not the most important factor in determining the rate of
fluid replacement. Fluid replacement is primarily guided by assessing the child's hydration
status through parameters such as urine output and clinical assessment.

Correct Answer is B
Explanation
These symptoms are indicative of hypoglycaemia, which occurs when the blood sugar levels drop too low. Providing a source of fast-acting carbohydrates, such as orange juice, can quickly raise the child's blood sugar levels and alleviate the symptoms.
Administering insulin (Option A) is incorrect because it is not appropriate in this situation because it would further lower the child's blood sugar levels.
Offering water (Option C) is incorrect because it would not effectively address the low blood sugar.
Glucagon (Option D) is incorrect because it is typically used in severe cases of hypoglycaemia when the child is unconscious or unable to swallow, and it requires a prescription. In this case, providing orange juice is the safest and most appropriate initial intervention. However, it is important to seek medical attention and inform the child's healthcare provider about the incident.
Correct Answer is D
Explanation
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
