Correct Answer: A

Rationale: A heart rate below 100 beats/min in a newborn indicates the need for positive pressure ventilation to improve oxygenation. Providing positive pressure ventilations helps in assisting the newborn's breathing efforts to ensure adequate oxygenation. Choice B, providing blow-by oxygen, may not be sufficient to address the underlying issue of inadequate breathing. Choice C, assessing the newborn's skin condition and color, is important but not the most immediate action needed for a heart rate below 100 beats/min. Choice D, starting chest compressions, is not indicated as the infant is breathing spontaneously and has a heart rate, albeit lower than normal, which does not warrant chest compressions.

Correct Answer: C

Rationale: The correct answer is C: reduction of edema. In acute glomerulonephritis, weight loss is often a result of the reduction of edema. Acute glomerulonephritis causes fluid retention and edema due to kidney inflammation. As the inflammation resolves with treatment, the kidneys can excrete excess fluid, leading to weight loss. Choices A, B, and D are incorrect. Poor appetite, increased potassium intake, and restriction to bed rest are not typically the primary reasons for weight loss in acute glomerulonephritis.

Correct Answer: C

Rationale: Low-set ears with lobe creases are often associated with genetic disorders and can indicate underlying chromosomal abnormalities. This physical characteristic is known to be a common sign in various syndromes like Down syndrome. Choices A, B, and D are not directly linked to genetic disorders. Feeding problems and specific weight/height measurements are more general indicators of growth and development, while the ability to hop on one foot but not skip is a developmental milestone assessment that does not specifically point towards a genetic disorder.

Correct Answer: A

Rationale: The correct answer is administering pancreatic enzymes. In cystic fibrosis, there is a deficiency in pancreatic enzymes, leading to poor digestion and malabsorption of nutrients. Administering pancreatic enzymes is essential to ensure proper digestion and absorption of nutrients. Providing respiratory therapy and nutritional support are important aspects of care for a child with cystic fibrosis, but addressing the pancreatic enzyme deficiency takes priority in this scenario. Encouraging physical activity is beneficial for overall health but is not the priority intervention in this case.

Correct Answer: B

Rationale: Choosing option B, 'Buy a soda and hamburger to eat,' is the most appropriate action for an adolescent with type 1 diabetes experiencing an insulin reaction during a basketball game. In this situation, the individual is likely experiencing hypoglycemia, and consuming a soda provides a quick source of sugar to raise blood glucose levels rapidly. The hamburger can offer a more sustained release of energy due to its protein and fat content. Option A is incorrect because while contacting parents for help may be necessary in some situations, immediate action to address hypoglycemia is crucial. Option C is incorrect because administering insulin would further lower blood sugar levels, worsening the condition. Option D is incorrect as leaving the arena without addressing the hypoglycemia can lead to a worsening of symptoms and potentially dangerous outcomes.
