Which factor predisposes the urinary tract to infection?

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.

The scenario describes a 14-year-old male who seems to be always eating, but his weight is appropriate for his height. In this case, it is important to reassure the parents that the behaviour may not necessarily be a cause for concern.

Option A provides an accurate response by explaining that for weight gain to occur, the individual would need to consume an excessive number of calories. Since the adolescent's weight is appropriate for his height, it suggests that his caloric intake is likely balanced and not excessive.

suggesting that he is substituting food for unfilled needs in (option B) is incorrect because it, is speculative and may not be accurate without further assessment or evidence. It is important to avoid making assumptions about underlying psychological or emotional reasons for increased eating without more information.

stating that this is normal due to an increase in body mass during this time in (option C) is incorrect because it, is not necessarily applicable to the scenario. While it is true that adolescents experience growth and changes in body composition during this period, it does not directly explain the constant eating behaviour described.

suggesting that this behaviour is abnormal and indicative of possible future obesity in (option D) is incorrect because it, may be premature and unsupported based solely on the information provided. It is essential to avoid making predictions or assumptions about future health outcomes without proper evaluation.

By providing the parents with information about the caloric intake required for weight gain and reassuring them that their son's eating behaviour may be within a normal range, the nurse can address their concerns and provide accurate guidance. If the parents have further concerned or questions, it may be appropriate to refer them to a healthcare provider for a more comprehensive assessment.
