A 12-year-old child whose weight and body mass index (BMI) are in the 75th percentile has a diastolic blood pressure that is between the 95th and 99th percentiles for age, sex, and height on three separate occasions. Which test will be prescribed for this child initially?
- A. complete blood count
- B. erythrocyte sedimentation rate

The nurse is caring for a school-age child who has had a cardiac catheterization. The child tells the nurse that the bandage is “too wet.†The nurse finds the bandage and bed soaked with blood. What is the priority nursing action?
- A. Notify physician
- B. Apply new bandage with more pressure
- C. Place the child in Trendelenburg position
- D. Apply direct pressure above catheterization site
Correct Answer: D
Rationale: If bleeding occurs, direct continuous pressure is applied 2.5 cm (1 inch) above the percutaneous skin site to localize pressure over the vessel puncture. Notifying a physician and applying a new bandage can be done after pressure is applied. The nurse can have someone else notify the physician while the pressure is being maintained. It is not a helpful intervention to place the girl in the Trendelenburg position. It would increase the drainage from the lower extremities.
