Pediatric Practice Exam HESI
1. A child has been admitted to the pediatric unit with a severe asthma attack. What type of acid-base imbalance should the nurse expect the child to develop?
- A. metabolic alkalosis due to insufficient production of acid metabolites
- B. respiratory alkalosis due to depressed respirations and retention of carbon dioxide
- C. respiratory acidosis due to impaired respirations and increased formation of carbonic acid
- D. metabolic acidosis due to the kidneys' inability to compensate for decreased carbonic acid formation
Correct answer: C
Rationale: In a severe asthma attack, the child is likely to develop respiratory acidosis. This occurs due to impaired respirations, leading to the retention of carbon dioxide and the formation of carbonic acid. Choice A is incorrect as metabolic alkalosis is not expected in this situation. Choice B is incorrect as respiratory alkalosis does not align with the scenario of impaired respirations in severe asthma attacks. Choice D is also incorrect as it describes metabolic acidosis, which is not typically associated with severe asthma attacks.
2. The healthcare professional is developing a teaching plan for a child who is to have their cast removed. What instruction would the professional most likely include?
- A. Applying petroleum jelly to the dry skin.
- B. Rubbing the skin vigorously to remove the dead skin.
- C. Soaking the area in warm water every day.
- D. Washing the skin with diluted peroxide and water.
Correct answer: C
Rationale: Soaking the area in warm water is the most appropriate instruction for a child who is having their cast removed. This method helps to gently remove dead skin without causing irritation. Applying petroleum jelly to dry skin (Choice A) is not recommended as it may not effectively aid in the removal of dead skin. Rubbing the skin vigorously (Choice B) can lead to skin irritation and should be avoided. Washing the skin with diluted peroxide and water (Choice D) may be too harsh, causing unnecessary irritation to the skin post-cast removal.
3. A child with a diagnosis of appendicitis is scheduled for surgery. What preoperative intervention is important for the nurse to perform?
- A. Administering antibiotics
- B. Maintaining strict NPO status
- C. Encouraging fluid intake
- D. Monitoring for signs of infection
Correct answer: B
Rationale: The correct preoperative intervention for a child with appendicitis scheduled for surgery is maintaining strict NPO (nothing by mouth) status. This is crucial to reduce the risk of aspiration during anesthesia induction and prevent potential complications during surgery. Administering antibiotics may be a part of the treatment plan but is not a preoperative intervention. Encouraging fluid intake is contraindicated preoperatively to avoid delays in surgery and complications related to anesthesia. Monitoring for signs of infection is important postoperatively to assess for any complications that may arise due to the surgical procedure.
4. What is the first action a healthcare provider should take before administering a tube feeding to an infant?
- A. Irrigate the tube with water.
- B. Offer a pacifier to the infant.
- C. Slowly instill 10 mL of formula.
- D. Place the infant in the Trendelenburg position.
Correct answer: B
Rationale: The correct answer is to offer a pacifier to the infant before administering tube feeding. Offering a pacifier helps stimulate the sucking reflex, preparing the infant for feeding and promoting digestion and comfort. Irrigating the tube with water (Choice A) is not typically the first action before tube feeding and may not be necessary. Slowly instilling formula (Choice C) should only be done after the infant is prepared for feeding. Placing the infant in the Trendelenburg position (Choice D) is not necessary and may not be recommended for tube feeding.
5. A health care provider orders a tap water enema for a 6-month-old infant with suspected Hirschsprung disease. What rationale causes the nurse to question the order?
- A. The result could lead to loss of necessary nutrients.
- B. It could cause a fluid and electrolyte imbalance.
- C. It could increase the fear of intrusive procedures.
- D. The result could cause shock from a sudden drop in temperature.
Correct answer: B
Rationale: The correct answer is B. Tap water enemas can cause significant fluid and electrolyte imbalances, particularly in infants, making them unsafe for this age group. Choice A is incorrect because tap water enemas do not directly lead to loss of necessary nutrients. Choice C is incorrect as it focuses on emotional impact rather than physiological risks. Choice D is incorrect as shock from a sudden drop in temperature is not a common consequence of a tap water enema in this scenario.
