HESI Practice Test Pediatrics Questions
Question 1 of 5
A child admitted with diabetic ketoacidosis is demonstrating Kussmaul respirations. The nurse determines that the increased respiratory rate is a compensatory mechanism for which acid-base alteration?
Correct Answer: D
Rationale: Kussmaul respirations are deep, rapid breathing patterns observed in metabolic acidosis, such as diabetic ketoacidosis. In this condition, the body tries to compensate for the acidic environment by increasing the respiratory rate to eliminate excess carbon dioxide (CO2) and decrease the acid levels, thereby helping to correct the acid-base imbalance. Therefore, the correct answer is metabolic acidosis.
Question 2 of 5
The healthcare provider is assessing an infant with diarrhea and lethargy. Which finding should the provider identify that is consistent with early dehydration?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
What suggestion should the nurse provide to prevent diaper rash in a 4-month-old infant as requested by the mother?
Correct Answer: C
Rationale: Using a barrier cream like zinc oxide forms a protective layer on the skin, creating a barrier against irritants and moisture, thus helping to prevent diaper rash. Unlike other options, barrier creams do not need to be completely removed at each diaper change, allowing the skin to remain protected between changes.
Question 4 of 5
What information should the nurse provide the parents of a 3-year-old boy with Duchenne muscular dystrophy (DMD) who are concerned about having more children?
Correct Answer: A
Rationale: The correct answer is A. Duchenne muscular dystrophy is an inherited X-linked recessive disorder that primarily affects male children in the family. Since it is X-linked, sons inherit the mutation from their mothers who are carriers of the abnormal gene. Therefore, the nurse should explain to the parents that any future sons they have would have a 50% chance of inheriting the mutation and having DMD, while daughters would have a 50% chance of being carriers like the mother.
Question 5 of 5
A 16-year-old female student with a history of asthma controlled with both an oral antihistamine and an albuterol (ProAir) metered-dose inhaler (MDI) comes to the school nurse. The student complains that she cannot sleep at night, feels shaky, and her heart feels like it is 'beating a mile a minute.' Which information is most important for the nurse to obtain?
Correct Answer: D
Rationale: The most crucial information for the nurse to obtain in this scenario is how often the metered-dose inhaler (MDI) is used daily. This information will help assess if the symptoms of insomnia, shakiness, and palpitations are potentially related to overuse of the inhaler, which can cause side effects such as tremors and palpitations. Monitoring the frequency of MDI usage is essential in managing asthma and ensuring appropriate medication administration.
