HESI Pediatrics Practice Exam
1. The child is 3 years old and is 2 hours postop from a cardiac catheterization via the right femoral artery. Which assessment finding indicates arterial obstruction?
- A. Blood pressure is decreasing, and the pulse is rapid and irregular.
- B. The right foot feels cool to the touch and appears pale and blanched.
- C. The pulse distal to the femoral artery is weaker in the left foot than the right foot.
- D. The pressure dressing at the right femoral area is damp and oozing blood.
Correct answer: B
Rationale: A cool, pale, and blanched foot is indicative of arterial obstruction, leading to poor blood flow. This finding requires immediate intervention to prevent further complications such as tissue damage or necrosis. Monitoring for signs of arterial compromise, such as color changes, temperature, and capillary refill, is crucial in detecting and managing vascular complications post-cardiac catheterization. Choices A, C, and D do not directly indicate arterial obstruction. While a decreasing blood pressure and rapid, irregular pulse may suggest compromise, these findings are more nonspecific. A weaker pulse distal to the femoral artery indicates reduced perfusion but not necessarily arterial obstruction. Finally, a damp, oozing pressure dressing suggests a dressing issue rather than arterial obstruction.
2. The practical nurse is caring for a child who has just returned from surgery for an appendectomy. Which intervention should the nurse implement?
- A. Encourage early ambulation.
- B. Apply warm compresses to the incision site.
- C. Monitor for signs of infection at the surgical site.
- D. Provide a high-fiber diet immediately post-op.
Correct answer: C
Rationale: Monitoring for signs of infection at the surgical site is crucial after an appendectomy as it helps in early detection and treatment of any potential complications. This intervention is essential for ensuring the child's proper healing and recovery post-surgery. Encouraging early ambulation is generally beneficial post-operatively but may not be the priority immediately after an appendectomy. Applying warm compresses to the incision site may not be indicated as it can increase the risk of infection. Providing a high-fiber diet immediately post-op is not recommended as the digestive system needs time to recover from surgery.
3. The practical nurse (PN) is caring for an adolescent who has been diagnosed with mononucleosis. Which activity should the PN advise the adolescent to avoid?
- A. Playing video games.
- B. Drinking caffeinated beverages.
- C. Participating in contact sports.
- D. Eating spicy foods.
Correct answer: C
Rationale: Contact sports should be avoided in mononucleosis due to the risk of spleen rupture, which is a serious complication of the disease. The spleen can enlarge in mononucleosis, making it more susceptible to injury from contact sports, potentially leading to a life-threatening situation if rupture occurs.
4. When should a mother introduce solid foods to her 4-month-old infant? The mother states that her mother suggests putting rice cereal in the baby's bottle. The nurse should instruct the mother to introduce solid foods when her child exhibits which behavior?
- A. Stops rooting when hungry
- B. Opens mouth when food is offered
- C. Awakens once for nighttime feedings
- D. Gives up a bottle for a cup
Correct answer: B
Rationale: Introducing solid foods when the child opens their mouth for food is important to ensure readiness for solids. This behavior indicates the infant's interest and readiness for new textures and flavors, promoting safe and successful introduction to solid foods. The other choices are not indicative of the infant's readiness for solid foods: A - stopping rooting is a reflex action, C - awakening for nighttime feedings is a normal behavior, and D - transitioning from a bottle to a cup is a developmental milestone unrelated to solid food introduction.
5. A child receives a prescription for amantadine 42 mg PO BID. Amantadine is available as a 50 mg/5 mL syrup. Using a supplied calibrated measuring device, how many mL should be administered per dose? (Round to the nearest tenth.)
- A. 4.2 mL
- B. 5 mL
- C. 3.6 mL
- D. 4 mL
Correct answer: A
Rationale: To calculate the mL per dose, divide the prescribed dose (42 mg) by the concentration of the syrup (50 mg/5 mL) and then convert the result to mL. 42 mg / 50 mg = 0.84. To find the amount in mL, multiply 0.84 by 5 mL, which equals 4.2 mL. Therefore, 4.2 mL should be administered per dose.
