1. When assessing a 5-year-old boy with major trauma, his blood pressure is 70/40 mm Hg, and his pulse rate is 140 beats/min and weak. The child's blood pressure:

• A. indicates decompensated shock.
• B. reflects adequate compensation.
• C. suggests increased intracranial pressure.
• D. is appropriate based on his age.

Correct answer: A

Rationale: In a 5-year-old boy with major trauma, a blood pressure of 70/40 mm Hg and a pulse rate of 140 beats/min, and weak, indicate decompensated shock. This presentation signifies inadequate perfusion, leading to compensatory mechanisms being overwhelmed, resulting in decompensated shock. Choice B is incorrect as the vital signs suggest the body is unable to adequately compensate for the trauma. Choice C is incorrect as the vital signs are more indicative of shock rather than increased intracranial pressure. Choice D is incorrect as such low blood pressure is not appropriate for a child of this age and indicates a critical condition.

2. Which of the following statements regarding febrile seizures in children is correct?

• A. They can occur even after a child has had a fever for longer than 24 hours.
• B. They can be caused by viral or bacterial meningitis.
• C. They do not typically occur on the first day of a fever.
• D. They typically last less than 15 minutes and often do not have a postictal phase.

Correct answer: D

Rationale: The correct answer is D. Febrile seizures in children typically last less than 15 minutes and often do not have a postictal phase, meaning there is usually no prolonged recovery period or confusion after the seizure. They are commonly associated with the rapid rise in body temperature at the onset of a fever, rather than the duration of the fever itself. Choices A, B, and C are incorrect because febrile seizures can occur even after a child has had a fever for longer than 24 hours, they can be caused by viral or bacterial meningitis, and they do not have a typical pattern of occurring on the first day of a fever.

3. The healthcare provider is assessing a newborn who is 2 hours old. Which finding requires immediate intervention?

• A. Acrocyanosis
• B. Respiratory rate of 60 breaths per minute
• C. Grunting with nasal flaring
• D. Heart rate of 140 beats per minute

Correct answer: C

Rationale: Grunting with nasal flaring is a concerning sign of respiratory distress in a newborn that can indicate inadequate oxygenation. This finding requires immediate intervention to ensure the newborn's respiratory status is stabilized and to prevent further complications. Prompt assessment and appropriate intervention are crucial in such cases to prevent respiratory compromise and potential deterioration. Acrocyanosis, which is bluish discoloration of the extremities, is a common finding in newborns and usually resolves on its own. A respiratory rate of 60 breaths per minute and a heart rate of 140 beats per minute are within normal ranges for a newborn and do not indicate immediate intervention is needed.

4. What is the reason for Asthma in 4-year-old Mabele, as Mrs. Joyce Thomson inquires? How would you explain it?

• A. Asthma occurs due to inflammation of the respiratory tract triggered by infections.
• B. An asthmatic attack can occur when the child is exposed to certain allergens, triggering an allergic reaction in the bronchioles that causes bronchial constriction.
• C. An asthmatic attack is a response to the release of inflammatory mediators to epithelial cells, affecting the autonomic neural control of the airway.
• D. Asthma is not an inborn problem; it involves abnormal growth of the bronchial tree causing restriction.

Correct answer: B

Rationale: Asthma in children like Mabele can be triggered by exposure to allergens, leading to an allergic reaction in the bronchioles. This reaction causes constriction of the bronchial tree, resulting in an asthmatic attack. It is essential for caregivers to identify and minimize exposure to these triggers to manage and prevent asthma episodes effectively.

5. Justine is admitted to the pediatric unit due to the occurrence of diabetic ketoacidosis signaling a new diagnosis of diabetes. The diabetes team explores the cause of the episode and takes steps to prevent a recurrence. Diabetic ketoacidosis (DKA) results from an excessive accumulation of which of the following?

• A. Sodium bicarbonate from renal compensation
• B. Potassium from cell death
• C. Glucose from carbohydrate metabolism
• D. Ketone bodies from fat metabolism

Correct answer: D

Rationale: Diabetic ketoacidosis (DKA) results from the excessive accumulation of ketone bodies from fat metabolism. During DKA, there is a lack of insulin leading to the breakdown of fat stores into fatty acids and their subsequent conversion into ketone bodies. These ketone bodies accumulate in the blood, leading to metabolic acidosis and the characteristic symptoms of DKA.
