1. In growing children, growth hormone deficiency results in short stature and very slow growth rates. Short stature may result from which of the following?

• A. Anterior pituitary gland hypofunction
• B. Posterior pituitary gland hyperfunction
• C. Parathyroid gland hyperfunction
• D. Thyroid gland hyperfunction

Correct answer: A

Rationale: Short stature in growing children can result from anterior pituitary gland hypofunction, which leads to growth hormone deficiency. The anterior pituitary gland plays a crucial role in stimulating the release of growth hormone, and when it is underactive (hypofunction), insufficient growth hormone is produced, resulting in short stature and slow growth rates.

2. The word hormone is derived from the Greek 'hormao' meaning 'I excite or arouse.' Hormones communicate this effect through their unique chemical structures recognized by specific receptors on their target cells, their patterns of secretion, and their concentrations in the general or local circulation. Which of the following is NOT a function of hormones?

• A. Producing new offspring
• B. Promoting growth and enhancing beauty
• C. Maintaining body temperature
• D. Fighting infections

Correct answer: A

Rationale: Hormones play a crucial role in various bodily functions such as regulating metabolism, growth, and maintaining homeostasis. However, producing new offspring involves reproductive processes controlled by other systems in the body, not directly by hormones.

3. 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.

4. Which of the following clinical signs would MOST suggest acute respiratory distress in a 2-month-old infant?

• A. Heart rate of 130 beats/min
• B. Respiratory rate of 30 breaths/min
• C. Abdominal breathing
• D. Grunting respirations

Correct answer: D

Rationale: Grunting respirations are a key clinical sign of acute respiratory distress in infants. Grunting is a protective mechanism where the infant exhales against a partially closed glottis to increase functional residual capacity and oxygenation. This is often seen in conditions such as respiratory distress syndrome, pneumonia, or other causes of respiratory compromise in infants. Monitoring respiratory patterns like grunting is crucial for early recognition and intervention in infants with respiratory distress. Choices A, B, and C are less specific to acute respiratory distress in infants. While an elevated heart rate and respiratory rate can be present in respiratory distress, grunting respirations are a more direct indicator of significant respiratory compromise in infants.

5. Serwaa, a 26-year-old mother has brought her daughter to the OPD with signs of lower respiratory tract infections. The following are the diagnoses that can be given to the daughter except:

• A. Pneumonia
• B. Asthma
• C. Bronchiolitis
• D. Coryza

Correct answer: D

Rationale: Coryza, also known as the common cold, primarily affects the upper respiratory tract and is not typically associated with lower respiratory tract infections. Pneumonia, asthma, and bronchiolitis are conditions that can manifest as lower respiratory tract infections.
