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. The parents of a child who is scheduled for open-heart surgery ask why their child must be subjected to chest tubes after surgery. What should the nurse consider before responding in language the parents will understand?
- A. They will increase tidal volumes.
- B. Drainage of air and fluid will be facilitated.
- C. They will maintain positive intrapleural pressure.
- D. Pressure on the pericardium and chest wall will be regulated.
Correct answer: B
Rationale: Chest tubes are necessary after open-heart surgery to facilitate the drainage of air and fluid from the chest cavity. These tubes help prevent complications such as pneumothorax (accumulation of air in the pleural space) or cardiac tamponade (build-up of fluid in the pericardial sac), which can be serious postoperative issues. Options A, C, and D are incorrect because chest tubes are primarily used for draining purposes and not for increasing tidal volumes, maintaining positive intrapleural pressure, or regulating pressure on the pericardium and chest wall.
3. A 4-year-old child is admitted to the hospital with a diagnosis of epiglottitis. What is the priority nursing intervention?
- A. Administer antibiotics
- B. Provide humidified oxygen
- C. Keep the child NPO
- D. Position the child upright
Correct answer: C
Rationale: The priority nursing intervention for a 4-year-old child admitted with epiglottitis is to keep the child NPO (nothing by mouth). This is crucial to prevent further airway compromise due to the inflamed epiglottis. Administering antibiotics may be necessary but is not the priority at this moment. Providing humidified oxygen can support oxygenation but does not address the immediate risk of airway obstruction. Positioning the child upright may help with breathing but does not address the risk of aspiration. Keeping the child NPO is essential to maintain a patent airway and prevent complications associated with epiglottitis.
4. What is the most common cause of shock (hypoperfusion) in infants and children?
- A. infection
- B. cardiac failure
- C. accidental poisoning
- D. severe allergic reaction
Correct answer: A
Rationale: Infection is the leading cause of shock in infants and children due to their heightened vulnerability to sepsis. Infants and children possess developing immune systems, rendering them more susceptible to infections that can progress to septic shock. While cardiac failure is a severe condition, it is not as commonly the primary cause of shock in this age group. Accidental poisoning, though a potential shock inducer, is less prevalent in infants and children compared to infections. Severe allergic reactions, though significant, are not as frequent as infections in precipitating shock in infants and children.
5. The nurse is assessing an infant and notes that the infant's urine has a mousy or musty odor. What would the nurse suspect?
- A. Maple syrup urine disease
- B. Tyrosinemia
- C. Phenylketonuria
- D. Trimethylaminuria
Correct answer: C
Rationale: The correct answer is C: Phenylketonuria (PKU). PKU is suggested by a mousy or musty odor of the urine, which is caused by the inability to metabolize phenylalanine. Choice A, Maple syrup urine disease, is characterized by a sweet-smelling urine. Choice B, Tyrosinemia, typically presents with cabbage-like odor in the urine. Choice D, Trimethylaminuria, is associated with a fishy odor in the urine, breath, and sweat.
