1. Beta-adrenergic agonists such as Salbutamol are given to Reggie, a child with asthma. Such drugs are administered primarily to 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 Salbutamol are used to dilate the bronchioles in asthma patients. This action helps in relieving bronchospasms and improving airflow to the lungs, making breathing easier for the individual. While reducing inflammation is an essential part of asthma management, beta-adrenergic agonists primarily work by relaxing the smooth muscles around the airways, leading to bronchodilation. Choices B, C, and D are incorrect because beta-adrenergic agonists are not primarily used to reduce secondary infections, decrease postnasal drip, or directly reduce airway inflammation in asthma patients.

2. In the pediatric ward at Nyamebekyere teaching hospital, when should oxygen be applied to children?

• A. Central cyanosis
• B. Respiratory rate >70 breaths per minute
• C. Grunting noted on assessment
• D. All of the above

Correct answer: D

Rationale: All the listed conditions, central cyanosis, respiratory rate >70 breaths per minute, and grunting on assessment, are indicative of the need for oxygen therapy. Central cyanosis suggests severe hypoxemia, a respiratory rate >70 breaths per minute can indicate respiratory distress, and grunting is a sign of increased work of breathing. Administering oxygen in these situations can help improve oxygenation and support the child's respiratory function, making option D the correct choice.

3. 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.

4. A 3-year-old child has a sudden onset of respiratory distress. The mother denies any recent illnesses or fever. You should suspect:

• A. croup.
• B. foreign body airway obstruction.
• C. lower respiratory infection.
• D. epiglottitis.

Correct answer: B

Rationale: In a 3-year-old child with a sudden onset of respiratory distress and no recent illnesses or fever, the likely cause is a foreign body airway obstruction. Foreign body obstruction can lead to sudden respiratory distress without other preceding symptoms. It is crucial to consider this possibility and act promptly to clear the airway in such cases to prevent serious complications.

5. Which type of diabetes mellitus (DM) is most likely the result of heterogeneous risk factors, making it preventable?

• A. Type 1
• B. Type 2
• C. Type 1 and 2
• D. Gestational diabetes

Correct answer: B

Rationale: Type 2 diabetes mellitus is most likely the result of heterogeneous risk factors, such as lifestyle choices and genetics, making it preventable. Type 1 diabetes, on the other hand, is an autoimmune condition that is not preventable. Gestational diabetes occurs during pregnancy and is not entirely preventable. Type 1 and 2 diabetes are distinct conditions, with Type 2 being the type associated with preventable risk factors.
