A nurse is reinforcing teaching with a parent of a child who has a sprained wrist. Which of the following interventions should the nurse instruct the parent to implement during the first 12 to 24 hours to minimize swelling?

Choice A rationale:
Swelling around the eyelids and mouth could indicate an allergic reaction, which can be severe in some cases. Anaphylaxis is a life-threatening reaction that can occur after immunizations. The nurse's priority is to assess and address any signs of an allergic reaction promptly. Swelling of the face, particularly around the eyes and mouth, is a red flag for potential anaphylaxis, and immediate intervention is necessary to prevent further complications.

Choice B rationale:
A temperature of 100.7 degrees Fahrenheit is considered a mild fever. While it's important to monitor for fever after immunizations, a mild fever alone may not be the nurse's top priority, especially if the child is otherwise stable. Fever can be a common post-immunization response and is often self-limiting.
Choice C rationale:
While monitoring the child's intake is important, only eating 2 ounces during the last feeding is not a priority concern compared to potential allergic reactions or fever. A temporary decrease in appetite following immunizations can be expected and might resolve on its own.
Choice D rationale:
Crying when the injection site is touched is a common response to discomfort from the shot. While it's essential to provide comfort and support to the child, this finding is not indicative of a severe reaction. It's not the nurse's priority compared to potential signs of an allergic reaction or a more significant fever.

Choice A rationale:
Hct 45% (Choice A) refers to the hematocrit level, which measures the proportion of blood volume occupied by red blood cells. While dehydration can lead to elevated hematocrit due to hemoconcentration, a hematocrit value of 45% is within the normal range for both males and females. Dehydration might cause a mild increase, but more significant elevations would be expected in cases of severe dehydration.
Choice B rationale:
Urine specific gravity 1.035 (Choice B) is an indicator of concentrated urine, which is a characteristic finding in dehydration. Dehydration reduces the body's water content, leading to more concentrated urine with higher specific gravity values. A normal range for urine-specific gravity is typically between 1.005 and 1.030.
Choice C rationale:
Capillary refill of less than 2 seconds (Choice C) is not a finding consistent with dehydration. Capillary refill time measures the time it takes for color to return to the nailbed after pressure is applied. Prolonged capillary refill time might indicate poor peripheral perfusion, which can be a sign of dehydration, but a refill time of less than 2 seconds is considered within the normal range.
Choice D rationale:
A urine output of 35 ml/hr (Choice D) is not indicative of dehydration. In fact, a urine output of 35 ml/hr is relatively normal and suggests adequate fluid intake and hydration. Dehydration would typically result in reduced urine output as the body conserves water.
