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: C

Rationale: In this scenario, the nurse failed to report or document the slow respiratory rate of the infant, which later led to severe respiratory distress. It is crucial to understand that any vital signs outside the expected range in an infant should be documented and reported promptly. This documentation is vital for monitoring the infant's condition, identifying potential issues, and ensuring timely intervention if needed. Choices A, B, and D are incorrect because they downplay the significance of abnormal vital signs and fail to emphasize the importance of documentation and reporting in infant care.

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: B

Rationale: It is recommended that a child should visit the dentist within the next few months after turning two years old. This allows for early dental check-ups to monitor oral health, detect any issues early on, and establish a good oral hygiene routine. Choice A ('Before starting school') is not as specific and may delay the child's first dental visit. Choice C ('When the first deciduous teeth are lost') is too late for the first dental visit, as preventive care should start earlier. Choice D ('At the next dental visit of a family member') is not ideal as the child's dental needs should be addressed independently of family members' visits.

Correct Answer: D

Rationale: In a child with hypothyroidism, weight gain is a typical finding due to the slowed metabolism associated with the condition. This occurs because thyroid hormone levels are insufficient to regulate metabolism effectively. Choices A, B, and C are not typically associated with hypothyroidism. Nervousness is more commonly seen in conditions like hyperthyroidism, where there is an excess of thyroid hormones. Heat intolerance may be seen in hyperthyroidism as well, where the body's metabolism is increased. Smooth velvety skin is a characteristic finding in conditions like Cushing's syndrome, where there is excess cortisol production.
