A nurse is admitting a 6-month-old infant who has dehydration. Which of the following amounts of urinary output should indicate to the nurse that the treatment has corrected the fluid imbalance?

Choice A reason: Elbow restraints are commonly used for infants who have undergone cleft lip and palate repair to prevent them from touching or rubbing their incisions, which could cause bleeding, infection, or disruption of the sutures¹².

Choice B reason: Wrist restraints are not appropriate for infants who have undergone cleft lip and palate repair because they do not prevent the infant from reaching their mouth with their fingers or objects. Wrist restraints are more suitable for older children or adults who need to avoid pulling out tubes or catheters³.

Choice C reason: Jacket restraints are not indicated for infants who have undergone cleft lip and palate repair because they do not restrict the movement of the arms or hands. Jacket restraints are more useful for children who need to be secured to a bed or chair to prevent falls or injuries³.

Choice D reason: Mummy restraints are not recommended for infants who have undergone cleft lip and palate repair because they immobilize the entire body and can cause respiratory distress, overheating, or skin breakdown. Mummy restraints are only used for short procedures that require minimal movement, such as venipuncture or lumbar puncture³.

Choice A reason: Blood pressure is not the most reliable indicator of fluid loss, as it can be affected by many other factors, such as cardiac output, vascular resistance, and blood volume. Blood pressure may not change significantly until the fluid loss is severe and the compensatory mechanisms are overwhelmed.

Choice B reason: Respiratory rate is not the most reliable indicator of fluid loss, as it can be affected by many other factors, such as oxygen demand, carbon dioxide levels, acid-base balance, and respiratory infections. Respiratory rate may increase as a result of fluid loss, but it is not a specific or sensitive sign.

Choice C reason: Skin integrity is not the most reliable indicator of fluid loss, as it can be affected by many other factors, such as age, nutrition, hydration, and skin diseases. Skin integrity may deteriorate as a result of fluid loss, but it is not a quantitative or objective measure.

Choice D reason: Body weight is the most reliable indicator of fluid loss, as it reflects the changes in the total body water and electrolytes. Body weight can be measured easily and accurately, and it can be compared with the previous or baseline values. A loss of more than 5% of the body weight indicates moderate dehydration, and a loss of more than 10% indicates severe dehydration.
