HESI Pediatrics Practice Exam

1. When reviewing developmental changes with the parents of a 6-month-old infant, what information should the practical nurse reinforce?

A. Encourage the infant to self-feed finger foods.
B. Teach the parents strategies to help the infant sit up.
C. Provide a developmentally safe environment for the infant.
D. Explain that an increased appetite typically occurs in the next 6 months.

Correct answer: C

Rationale: The correct answer is C because providing a developmentally safe environment for a 6-month-old infant is crucial as they begin to explore their surroundings more actively. This includes ensuring that the environment is free of hazards and that the infant is supervised to prevent accidents. Choice A is incorrect because self-feeding finger foods may not be developmentally appropriate for a 6-month-old infant. Choice B is incorrect as most infants are able to sit up with support around 6 months of age without the need for specific teaching strategies. Choice D is also incorrect as while appetite changes can occur, explaining a specific increase in appetite over the next 6 months is not a primary focus when discussing developmental changes with parents of a 6-month-old.

2. An infant with tetralogy of Fallot becomes acutely cyanotic and hyperpneic. Which action should the nurse implement first?

A. Administer morphine sulfate.
B. Start IV fluids.
C. Place the infant in a knee-chest position.
D. Provide 100% oxygen by face mask.

Correct answer: C

Rationale: In a situation where an infant with tetralogy of Fallot is acutely cyanotic and hyperpneic, the priority action should be to place the infant in a knee-chest position. This position helps increase systemic vascular resistance, improving pulmonary blood flow and subsequently ameliorating the cyanosis and hyperpnea. It is a non-invasive and effective intervention that can be promptly implemented by the nurse to address the immediate respiratory distress. Administering morphine sulfate (Choice A) is not the priority in this case as it may cause further respiratory depression. Starting IV fluids (Choice B) may not address the immediate cyanosis and hyperpnea. Providing 100% oxygen by face mask (Choice D) can help with oxygenation but may not be as effective as placing the infant in a knee-chest position to improve blood flow dynamics.

3. A mother brings her 3-month-old infant to the clinic because the baby does not sleep through the night. Which finding is most significant in planning care for this family?

A. The mother is a single parent and lives with her parents
B. The mother states the baby is irritable during feedings
C. The infant's formula has been changed twice
D. The diaper area shows severe skin breakdown

Correct answer: D

Rationale: Severe skin breakdown in the diaper area is significant as it indicates a potential severe issue that needs immediate attention to prevent further complications. Skin breakdown can lead to infections and discomfort for the infant, making it a priority in planning care for this family. The other findings, such as the mother's living situation, baby's irritability during feedings, or formula changes, are important but do not pose immediate risks to the infant's health compared to severe skin breakdown.

4. A 6-month-old female is scheduled to receive diphtheria, tetanus toxoid, and acellular pertussis vaccine (DTaP) and IPV (inactivated poliovirus vaccine) immunizations. She is recovering from a cold but is otherwise healthy and afebrile. Her 5-year-old sister is receiving chemotherapy. Which considerations should the nurse make for this situation?

A. DTaP and IPV can be safely given to the infant at the scheduled time.
B. DTaP and IPV are contraindicated because the infant has a cold.
C. IPV is contraindicated because her sister is immunocompromised.
D. DTaP is contraindicated because her sister is immunocompromised.

Correct answer: A

Rationale: DTaP and IPV can be safely administered to a child with a mild illness like a cold, even if there is an immunocompromised family member, as these vaccines do not contain live viruses. It is important to ensure that the child is otherwise healthy and afebrile before administering the vaccines. The presence of a cold is not a contraindication for receiving DTaP and IPV vaccines. Choice A is correct because the infant can receive both vaccines as scheduled. Choice B is incorrect as having a cold does not contraindicate DTaP and IPV administration. Choice C is incorrect because IPV is not contraindicated due to the sister's immunocompromised status. Choice D is incorrect as both DTaP and IPV can be given in this scenario.

5. A mother brings her 3-week-old infant to the clinic because the baby vomits after eating and always seems hungry. Further assessment indicates that the infant's vomiting is projectile, and the child seems listless. Which additional assessment finding indicates the possibility of a life-threatening complication?

A. Irregular palpable pulse
B. Hyperactive bowel sounds
C. Underweight for age
D. Crying without tears

Correct answer: D

Rationale: Crying without tears is a sign of severe dehydration, which is a potentially life-threatening complication in infants with projectile vomiting. Dehydration can rapidly progress in infants, leading to serious consequences if not promptly addressed. The combination of projectile vomiting, listlessness, and absence of tears when crying should raise concerns about severe dehydration and the need for urgent intervention to prevent further complications.
