Pediatric Practice Exam HESI
1. During a routine monthly examination, a 5-month-old infant is brought to the pediatric clinic. What assessment finding should alert the nurse to notify the health care provider immediately?
- A. Temperature of 99.5°F
- B. Blood pressure of 75/48 mm Hg
- C. Heart rate of 100 beats per minute
- D. Respiratory rate of 50 breaths per minute
Correct answer: D
Rationale: A respiratory rate of 50 breaths per minute in a 5-month-old infant is higher than the expected range and may indicate respiratory distress. This finding is concerning and should prompt the nurse to notify the health care provider for further evaluation and intervention. A temperature of 99.5°F, blood pressure of 75/48 mm Hg, and heart rate of 100 beats per minute are within normal ranges for a 5-month-old infant. Elevated temperature may indicate a mild fever, which can be monitored. A blood pressure of 75/48 mm Hg is within the normal range for infants. A heart rate of 100 beats per minute is also within the expected range for a 5-month-old infant and does not typically require immediate notification of the health care provider.
2. While performing a visual inspection of a 30-year-old woman in active labor, you can see the umbilical cord at the vaginal opening. After providing high concentration oxygen, you should next
- A. massage the uterus to facilitate delivery of the fetus
- B. relieve pressure from the cord with your gloved fingers
- C. place the mother on her left side and provide rapid transport
- D. elevate the mother's lower extremities and provide immediate transport
Correct answer: B
Rationale: In the scenario described, when the umbilical cord is visible at the vaginal opening, the priority is to relieve pressure from the cord with gloved fingers. This action helps prevent cord compression and ensures continued oxygenation to the fetus, which is crucial for the baby's well-being. Massaging the uterus or elevating the mother's lower extremities is not the correct course of action in this situation and may potentially worsen the condition. Placing the mother on her left side and providing rapid transport is not the immediate step needed to address the visible umbilical cord; relieving pressure from the cord takes precedence to maintain fetal oxygen supply.
3. The nurse is teaching a group of students about myelination in a child. Which statement by the students indicates that the teaching was successful?
- A. Myelination continues into adolescence and beyond.
- B. The process occurs in a cephalocaudal (head-to-toe) pattern.
- C. Myelination decreases the speed of nerve impulses.
- D. Myelination decreases the specificity of nerve impulses.
Correct answer: B
Rationale: The correct answer is B. Myelination occurs in a cephalocaudal (head-to-toe) pattern, improving nerve function progressively. Choice A is incorrect as myelination continues into adolescence and beyond, not just during childhood. Choice C is incorrect because myelination actually increases the speed of nerve impulses rather than decreasing it. Choice D is incorrect as myelination enhances the specificity of nerve impulses, making them more efficient and precise rather than less specific.
4. What is the priority nursing intervention for a child admitted to the hospital with a diagnosis of acute glomerulonephritis?
- A. Monitoring for hypertension
- B. Providing pain relief
- C. Restricting fluid intake
- D. Encouraging fluid intake
Correct answer: A
Rationale: The priority nursing intervention for a child with acute glomerulonephritis is monitoring for hypertension. Acute glomerulonephritis involves inflammation of the kidney's glomeruli, leading to impaired kidney function. Hypertension is a common complication due to fluid retention and increased renin-angiotensin system activity. Monitoring for hypertension is crucial for early detection and management to prevent further kidney damage and complications. Providing pain relief (Choice B) may be required for discomfort but is not the priority. Restricting fluid intake (Choice C) may be necessary in some kidney diseases, but in acute glomerulonephritis, the focus is on monitoring and managing hypertension. Encouraging fluid intake (Choice D) is inappropriate as it can exacerbate fluid overload and hypertension in acute glomerulonephritis.
5. The parents of a 6-week-old infant who was born without an immune system ask a nurse why their baby is still so healthy. How should the nurse reply?
- A. Exposure to pathogens during this time can be limited.
- B. Some antibodies are produced by the infant’s colonic bacteria.
- C. Antibodies are passively received from the mother through the placenta and breast milk.
- D. Fewer antibodies are produced by the fetal thymus during the eighth and ninth months of gestation.
Correct answer: C
Rationale: The correct answer is C. Infants receive passive immunity through antibodies from the mother during pregnancy and breastfeeding, which protect them initially. Choice A is incorrect because a 6-week-old infant born without an immune system would not be able to limit exposure to pathogens effectively. Choice B is incorrect as antibodies produced by colonic bacteria are not a significant source of immunity in infants. Choice D is incorrect as the fetal thymus primarily plays a role in T cell development rather than antibody production during gestation.
