1. What is critical for preventing complications in an infant with hypothyroidism?

• A. Excessive growth
• B. Cognitive impairment
• C. Damage to the nervous system
• D. Damage to the urinary system

Correct answer: B

Rationale: The correct answer is B: Cognitive impairment. In infants with hypothyroidism, prompt administration of oral thyroid hormone replacement is crucial to prevent cognitive impairment and other serious complications. Excessive growth (choice A) is not a typical complication of hypothyroidism in infants. While hypothyroidism can affect the nervous system (choice C), cognitive impairment is more specific to untreated cases. Damage to the urinary system (choice D) is not a common complication of hypothyroidism in infants.

2. How should a healthcare professional manage a child with a newly inserted central venous catheter?

• A. Monitor for signs of infection
• B. Restrict all physical activity
• C. Administer routine antibiotics
• D. Increase fluid intake only

Correct answer: A

Rationale: Monitoring for signs of infection is crucial in managing a central venous catheter to prevent complications. This involves observing for redness, swelling, warmth, or drainage at the catheter site, as these can indicate an infection. Restricting physical activity unnecessarily (choice B) can hinder the child's recovery and quality of life. Administering routine antibiotics (choice C) without a confirmed infection can lead to antibiotic resistance and unnecessary side effects. Increasing fluid intake only (choice D) is not the primary intervention for managing a central venous catheter.

3. What is a key intervention for a child with a new diagnosis of asthma?

• A. Provide a peak flow meter
• B. Limit all physical activity
• C. Increase dairy consumption
• D. Recommend frequent use of nasal decongestants

Correct answer: A

Rationale: The correct answer is A: Provide a peak flow meter. Providing a peak flow meter is crucial for a child with a new diagnosis of asthma as it helps monitor asthma control and manage symptoms by tracking changes in airflow. This device assists in assessing how well the lungs are functioning and guides treatment decisions. Limiting all physical activity (choice B) is not recommended as regular exercise can actually help improve lung function in asthmatic children. Increasing dairy consumption (choice C) is not a key intervention for asthma, and recommending frequent use of nasal decongestants (choice D) is not suitable for asthma management in children.

4. How much energy is required to raise the temperature of one kilogram of water by 1°C?

• A. 10 calories
• B. 100 calories
• C. 1 kilocalorie
• D. 10 kilocalories

Correct answer: C

Rationale: The correct answer is 1 kilocalorie. This is the amount of energy required to raise the temperature of 1 kilogram of water by 1°C. Choice A (10 calories) and Choice D (10 kilocalories) are incorrect as they do not represent the correct unit of measurement for this specific scenario. Choice B (100 calories) is also incorrect as it overestimates the amount of energy required. The specific heat capacity of water is approximately 1 calorie/gram °C, which means that 1 kilogram (1000 grams) of water requires 1 kilocalorie (1000 calories) to raise its temperature by 1°C.

5. What is a common sign of congenital hip dysplasia in infants?

• A. Symmetrical hip movement
• B. Limited range of motion in the hip
• C. Swelling of the knees
• D. Dislocated patella

Correct answer: B

Rationale: Limited range of motion in the hip, often noted as a limitation in abduction, is a common sign of congenital hip dysplasia. This limitation is due to the abnormal development of the hip joint, affecting its movement. Symmetrical hip movement (Choice A) is not a characteristic sign of congenital hip dysplasia. Swelling of the knees (Choice C) is not typically associated with this condition. Dislocated patella (Choice D) refers to a different anatomical structure and is not a common sign of congenital hip dysplasia.
