1. Beta-adrenergic agonists such as albuterol are given to Reggie, a child with asthma, to primarily do which of the following?

• A. Dilate the bronchioles
• B. Reduce secondary infections
• C. Decrease postnasal drip
• D. Reduce airway inflammation

Correct answer: A

Rationale: Beta-adrenergic agonists like albuterol are bronchodilators that primarily work by relaxing and dilating the bronchioles, which helps to alleviate bronchoconstriction, a characteristic feature of asthma. This action leads to improved airflow and easier breathing for individuals experiencing asthma symptoms.

2. 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.

3. You arrive at a residence shortly after a 4-year-old boy experienced an apparent febrile seizure. The child is alert and crying. His skin is flushed, hot, and moist. His mother tells you that the seizure lasted about 2 minutes. You should:

• A. provide supportive care and transport.
• B. give him acetaminophen or ibuprofen.
• C. begin rapid cooling measures at once.
• D. allow the mother to take her child to the doctor.

Correct answer: A

Rationale: After a febrile seizure, the recommended course of action is to provide supportive care and transport the child to a medical facility. Supportive care may include ensuring a safe environment, monitoring the child, and seeking medical evaluation to determine the underlying cause of the seizure and appropriate management.

4. What action should you take if a newborn's heart rate is 50 beats/min?

• A. Begin chest compressions.
• B. Reassess in 30 seconds.
• C. Administer blow-by oxygen.
• D. Start positive-pressure ventilations.

Correct answer: D

Rationale: If a newborn's heart rate is below 60 beats per minute, the appropriate action is to start positive-pressure ventilations. Ventilations help deliver oxygen to the newborn's body and support respiratory function, which is critical in cases of bradycardia. Chest compressions are not recommended until the heart rate is below 60 despite adequate ventilation. Reassessment is essential but not the immediate action required in this scenario. Administering blow-by oxygen alone may not effectively address the underlying cause of bradycardia, making positive-pressure ventilations the priority intervention in this case.

5. If a baby weighs 14 kg, how much fluid should be administered to the baby over 24 hours using a rate of 100 ml/kg?

• A. 1400ml
• B. 2600ml
• C. 1650ml
• D. 3360ml

Correct answer: A

Rationale: To calculate the fluid requirement for a baby, multiply the weight of the baby (14 kg) by the fluid rate (100 ml/kg): 14 kg x 100 ml/kg = 1400 ml. Therefore, the correct answer is 1400 ml.
