Pediatric Practice Exam HESI
1. A nurse on the pediatric unit is observing the developmental skills of several 2-year-old children in the playroom. Which child should the nurse continue to evaluate?
- A. Cannot stand on one foot
- B. Builds a tower of 7 blocks
- C. Uses echolalia when speaking
- D. Colors outside the lines of a picture
Correct answer: C
Rationale: The correct answer is C. Using echolalia, which is the repetition of words or phrases, is not typical for a 2-year-old child and may indicate the need for further evaluation. Choices A, B, and D are all within the expected developmental skills for a 2-year-old. While most 2-year-olds may not be able to stand on one foot, it is not a cause for concern at this age. Building a tower of 7 blocks and coloring outside the lines of a picture are both appropriate for a 2-year-old's developmental skills.
2. A nurse is assessing a child with suspected pertussis. What clinical manifestation is the nurse likely to observe?
- A. Dry, hacking cough
- B. Inspiratory stridor
- C. Nasal congestion
- D. Severe coughing spells
Correct answer: D
Rationale: The correct answer is D: Severe coughing spells. Pertussis, also known as whooping cough, typically presents with severe coughing spells that can be followed by a characteristic 'whoop' sound. These coughing fits can be intense and prolonged, often causing the child to gasp for air between coughs. Option A, dry hacking cough, is a common symptom of other respiratory conditions like bronchitis. Option B, inspiratory stridor, is more commonly associated with conditions like croup. Option C, nasal congestion, is not a typical symptom of pertussis.
3. A child with sickle cell anemia develops severe chest pain, fever, a cough, and dyspnea. The nurse's first action is to
- A. administer 100% oxygen to relieve hypoxia
- B. administer pain medication to relieve symptoms
- C. notify the practitioner because chest syndrome is suspected
- D. notify the practitioner because the child may be having a stroke
Correct answer: C
Rationale: In a child with sickle cell anemia experiencing severe chest pain, fever, cough, and dyspnea, the priority action is to suspect acute chest syndrome, a life-threatening complication. The nurse's first action should be to notify the practitioner for immediate evaluation and intervention. Administering 100% oxygen (Choice A) may be necessary later but is not the initial priority. Administering pain medication (Choice B) should not precede notifying the practitioner, as addressing the underlying cause is crucial. The symptoms described are more indicative of acute chest syndrome than a stroke, so notifying the practitioner for chest syndrome (Choice C) takes precedence over suspecting a stroke (Choice D).
4. When teaching a class about trisomy 21, the instructor would identify the cause of this disorder as:
- A. nondisjunction.
- B. X-linked recessive inheritance.
- C. genomic imprinting.
- D. autosomal dominant inheritance.
Correct answer: A
Rationale: Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division that leads to the presence of an extra chromosome 21. This additional chromosome alters the normal genetic makeup, resulting in the characteristics associated with Down syndrome. Therefore, the correct answer is nondisjunction (Choice A). Choices B, C, and D are incorrect because Trisomy 21 is not caused by X-linked recessive inheritance, genomic imprinting, or autosomal dominant inheritance. Understanding the specific genetic mechanism involved in Trisomy 21 is crucial for grasping the basis of this chromosomal disorder.
5. During a health assessment of a school-age child, where should the nurse focus more attention based on the child's developmental level?
- A. Infections
- B. Poisonings
- C. Risk-taking behaviors
- D. Accidents and injuries
Correct answer: D
Rationale: During the school-age period, children are active, curious, and engaged in various physical activities, making them more susceptible to accidents and injuries. This developmental stage is characterized by increased motor skills and exploration, leading to a higher risk of unintentional harm. While infections, poisonings, and risk-taking behaviors are also concerns for school-age children, focusing on preventing and addressing accidents and injuries is essential due to their heightened physical activity and curiosity.
