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: D

Rationale: The correct answer is D: 'It is a connection between the pulmonary artery and the aorta.' Patent ductus arteriosus (PDA) is an abnormal connection between the pulmonary artery and the aorta, which normally closes after birth. Choices A, B, and C describe different cardiac conditions and do not accurately define PDA. Choice A is incorrect because PDA does not involve the diameter of the aorta being enlarged. Choice B is incorrect because PDA does not involve the wall between the right and left ventricles being open. Choice C is incorrect because PDA is not a narrowing of the entrance to the pulmonary artery.

Correct Answer: B

Rationale: The correct answer is to monitor for signs of dehydration. After treatment for dehydration, it is crucial to educate caregivers about recognizing early signs of dehydration to prevent its recurrence. Monitoring for dehydration ensures that appropriate measures can be taken promptly if signs reappear. Choices A, C, and D are incorrect because infection, hypovolemia, and malnutrition, while important considerations in healthcare, are not the primary focus after treating dehydration in a 3-year-old child.

Correct Answer: A

Rationale: Checking blood glucose levels before meals and at bedtime is essential in managing type 1 diabetes mellitus as it helps in monitoring blood sugar levels at different times of the day and adjusting insulin doses accordingly. Option B about using a lancet device to obtain blood samples is a technique rather than an emphasis on monitoring frequency. Option C suggesting the use of urine test strips is incorrect as urine test strips are not recommended for accurate real-time monitoring of blood glucose levels in type 1 diabetes. Option D, recognizing signs of hypoglycemia, is important but not the primary emphasis when educating about blood glucose monitoring.

Correct Answer: A

Rationale: The correct answer is administering pancreatic enzymes. In cystic fibrosis, the pancreas is often affected, leading to insufficient production of digestive enzymes. Administering pancreatic enzymes is crucial to ensure proper digestion and absorption of nutrients. While respiratory therapy, nutritional support, and physical activity are essential components of care for individuals with cystic fibrosis, addressing the digestive aspect by administering pancreatic enzymes takes priority to prevent malnutrition and promote overall health.
