1. 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?
- A. Metabolic alkalosis.
- B. Respiratory acidosis.
- C. Respiratory alkalosis.
- D. Metabolic acidosis.
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.
2. A mother brings her 2-year-old son to the clinic because he has been crying and pulling on his earlobe for the past 12 hours. The child’s oral temperature is 101.2°F. Which intervention should the nurse implement?
- A. Ask the mother if the child has had a runny nose
- B. Cleanse purulent exudate from the affected ear canal
- C. Apply a topical antibiotic to the periauricle area
- D. Provide parent education to prevent recurrence
Correct answer: A
Rationale: In a child with ear pain and fever, asking about a runny nose is important to assess if the ear pain is associated with a respiratory infection, such as otitis media. This information can guide further assessment and treatment decisions. Choice B is incorrect because cleansing purulent exudate should be done by a healthcare provider, not the nurse. Choice C is incorrect as topical antibiotics should only be applied under healthcare provider's orders. Choice D is not the priority at this moment, as the immediate concern is assessing the association between the ear pain and a possible respiratory infection.
3. A 10-year-old child is brought to the emergency department after falling from a bicycle and hitting their head. The nurse notes that the child is drowsy and has a headache. What is the nurse’s priority action?
- A. Perform a full neurological assessment
- B. Administer pain medication
- C. Allow the child to rest quietly
- D. Check the child's immunization status
Correct answer: A
Rationale: In a child who has fallen and hit their head, presenting with drowsiness and headache, the priority action for the nurse is to perform a full neurological assessment. This is crucial to evaluate the extent of the head injury and monitor for signs of increased intracranial pressure, which could indicate a more severe traumatic brain injury. Administering pain medication or allowing the child to rest quietly are not appropriate initial actions without first assessing the neurological status. Checking the child's immunization status is important for overall health but is not the priority in this acute situation.
4. A 4-month-old girl is brought to the clinic by her mother because she has had a cold for 2 to 3 days and woke up this morning with a hacking cough and difficulty breathing. Which additional assessment finding should alert the nurse that the child is in acute respiratory distress?
- A. Bilateral bronchial breath sounds.
- B. Diaphragmatic respiration.
- C. A resting respiratory rate of 35 breaths per minute.
- D. Flaring of the nares.
Correct answer: D
Rationale: Flaring of the nares is a clinical sign of acute respiratory distress in infants. It indicates an increased effort to breathe and is a crucial finding that requires immediate attention, as it signifies the child is having difficulty breathing and may be in respiratory distress. Choices A, B, and C are incorrect. Bilateral bronchial breath sounds may be present in conditions like pneumonia but do not specifically indicate acute respiratory distress. Diaphragmatic respiration is a normal breathing pattern and not a sign of distress. A resting respiratory rate of 35 breaths per minute in a 4-month-old infant is within the expected range, so it does not necessarily indicate acute respiratory distress.
5. The nurse is caring for a 2-year-old child who was admitted for dehydration due to gastroenteritis. The child is now receiving IV fluids and appears more alert. What is the best indicator that the child’s condition is improving?
- A. The child is more alert and playful
- B. The child’s urine output has increased
- C. The child’s vital signs are stable
- D. The child is tolerating small amounts of oral fluids
Correct answer: B
Rationale: Increased urine output is a reliable indicator that hydration status is improving. While alertness and playfulness are positive signs, increased urine output directly reflects improved hydration. Stable vital signs are important but may not directly indicate hydration status. Tolerating small amounts of oral fluids is a good sign but may not be as direct an indicator as increased urine output.
