HESI Pediatric Practice Exam
1. When reinforcing information about the use of corticosteroids in treating asthma in children, which statement indicates that the parent understands the teaching?
- A. My child should take the medication only when experiencing symptoms.
- B. I will rinse my child's mouth after each use of the inhaler.
- C. I should discontinue the medication if my child seems better.
- D. Corticosteroids are used for quick relief during an asthma attack.
Correct answer: B
Rationale: Rinsing the mouth after using corticosteroid inhalers is crucial as it helps prevent oral thrush, a common side effect associated with these medications. This practice reduces the risk of developing fungal infections in the mouth and throat, maintaining optimal oral health during asthma treatment.
2. The healthcare provider is providing preconception counseling. Which supplement should the provider recommend to help prevent the occurrence of anencephaly?
- A. Folic Acid.
- B. Calcium.
- C. Iron.
- D. Vitamin D.
Correct answer: A
Rationale: Folic acid supplementation before and during early pregnancy is crucial for reducing the risk of neural tube defects, including anencephaly. Anencephaly is a severe birth defect in which a baby is born without parts of the brain and skull. Folic acid plays a key role in neural tube development and can significantly lower the chances of such defects when taken prior to conception and in early pregnancy.
3. A mother brings her 3-month-old infant to the clinic, concerned about frequent vomiting after feeding. The practical nurse (PN) suspects gastroesophageal reflux (GER). Which recommendation should the PN provide to the mother?
- A. Feed the infant in a prone position.
- B. Provide larger, less frequent feedings.
- C. Keep the infant upright for 30 minutes after feeding.
- D. Offer only formula thickened with rice cereal.
Correct answer: C
Rationale: The correct recommendation for reducing symptoms of gastroesophageal reflux (GER) in infants is to keep the infant upright for 30 minutes after feeding. This position helps prevent the backflow of stomach contents, alleviating symptoms of reflux. Placing the infant in a prone position or providing larger, less frequent feedings may worsen symptoms by increasing the likelihood of regurgitation. Offering only formula thickened with rice cereal is not the first-line intervention for GER and should not be recommended initially.
4. After an endotracheal tube is placed in a client who experienced sudden onset of respiratory distress, what should the nurse do?
- A. Secure the tube in place with tape
- B. Order a chest x-ray for the client
- C. Document the depth of tube insertion
- D. Auscultate both lungs for breath sounds
Correct answer: D
Rationale: After endotracheal tube insertion, the nurse should auscultate both lungs for the presence of breath sounds. This step helps confirm proper tube placement and adequate ventilation. Auscultation of breath sounds is crucial to ensure that the tube is correctly positioned in the trachea and not in the esophagus. While securing the tube with tape is important, it is not the immediate priority after insertion. Ordering a chest x-ray may be necessary but is not the first action to take immediately post-intubation. Documenting the depth of tube insertion is important but ensuring proper ventilation through auscultation takes precedence.
5. The nurse is administering total parenteral nutrition (TPN) via a central line at 75 ml/hour to a client who had a bowel resection 4 days ago. Which laboratory finding requires the most immediate intervention by the nurse?
- A. Blood glucose of 140 mg/dL
- B. White blood cell count of 8000/mm³
- C. Serum potassium of 3.8 mEq/L
- D. Serum calcium of 7.8 mg/dL
Correct answer: D
Rationale: The correct answer is D. A serum calcium level of 7.8 mg/dL requires immediate intervention due to the risk of hypocalcemia. Hypocalcemia can lead to serious complications such as tetany, seizures, and cardiac arrhythmias. The other laboratory findings are within normal limits or slightly elevated, which do not pose an immediate threat to the client's health in this scenario.
