Correct Answer: B

Rationale: Marking the point of measurement ensures consistent and accurate assessments of abdominal circumference, especially important in conditions like bowel obstruction where changes need to be monitored closely.

Correct Answer: B

Rationale: The correct answer is B, self-actualization. Self-actualization is the highest level in Maslow's hierarchy of needs, representing the realization of one's full potential. While love is an essential need, self-actualization builds upon the fulfillment of basic needs like safety and love. Esteem needs relate to feelings of accomplishment and recognition, which come before self-actualization. Physiological needs such as food, water, and shelter are the most basic needs at the bottom of the hierarchy.

Correct Answer: C

Rationale: The correct answer is C: 'Barking cough and inspiratory stridor.' Classic signs of laryngotracheobronchitis (LTB) include a barking cough, often described as a seal-like cough, and inspiratory stridor, which is a high-pitched sound heard during inspiration. These symptoms occur due to inflammation and narrowing of the upper airway. Choices A, B, and D are incorrect as they do not align with the typical assessment findings of LTB. Cyanosis and dyspnea (Choice A) may occur in severe cases but are not specific to LTB. Productive cough and high fever (Choice B) are more indicative of lower respiratory tract infections. Pale laryngeal and dyspnea (Choice D) are not characteristic findings of LTB.

Correct Answer: A

Rationale: The correct answer is A: Petechiae, fever, fatigue. Children with leukemia commonly present with petechiae (due to low platelet count), fever (due to infection), and fatigue (due to anemia), which are classic manifestations of the disease. Option B is incorrect because headache, papilledema, and irritability are more indicative of increased intracranial pressure, not leukemia. Option C is incorrect as muscle wasting and weight loss are not typical initial manifestations of leukemia in children. Option D is incorrect as decreased intracranial pressure, psychosis, and confusion are not commonly associated with leukemia.

Correct Answer: A

Rationale: The primary reason for correcting cryptorchidism through surgery is to prevent damage to the undescended testicle, which can lead to infertility and increase the risk of testicular cancer. Prevention of UTIs and prostate cancer are not the primary concerns in this context.
