Correct Answer: D

Rationale: Neuroblastoma, a common solid tumor in children, often presents with symptoms related to the mass effect it causes. Abdominal mass and weakness are classic signs of neuroblastoma due to the tumor originating in the adrenal glands near the kidneys and potentially compressing nearby structures. Lymphedema and nerve palsy (Choice A) are not typically associated with neuroblastoma. Hearing loss and ataxia (Choice B) are more common in conditions affecting the central nervous system rather than neuroblastoma. Headaches and vomiting (Choice C) are nonspecific symptoms and are less commonly linked to neuroblastoma compared to the characteristic abdominal findings.

Correct Answer: B

Rationale: Maintaining sterile technique when performing tracheostomy care is essential in preventing infections and complications. Option A is incorrect because povidone-iodine may be too harsh for cleaning around the stoma and can lead to skin irritation. Option C is incorrect because suctioning a tracheostomy should be done using sterile technique to minimize the risk of introducing pathogens. Option D is incorrect as tracheostomy ties need to be changed more frequently, usually every 1-2 days, to prevent skin breakdown and infection.

Correct Answer: A

Rationale: The correct answer is A: Collaborating with providers to perform obesity screenings during routine office visits. This is a primary health care strategy as it focuses on prevention and early detection, which are key components of managing obesity. Screening during routine visits allows for timely identification of obesity and related health risks, enabling early intervention. Choices B, C, and D do not align with primary health care strategies for obesity. Ensuring availability of specialized beds, providing intraoperative training, and educating about postoperative complications are more focused on secondary and tertiary levels of care, rather than primary prevention and early detection.

Correct Answer: A

Chicken breast is a high-protein food that should be limited in such diets to help manage the progression of kidney disease. Choices B, C, and D are low in protein and are generally suitable for individuals following a low-protein diet. Apples, rice, and bananas can be included in moderation as part of a balanced diet for individuals with chronic kidney disease.
