Correct Answer: A

Rationale: The correct answer is A: Setting goals that are focused on developing healthier lifestyles. This approach is essential in combating childhood obesity as it promotes sustainable habits and behaviors. Option B, developing strict diet plans, may not be effective in the long term and could lead to unhealthy relationships with food. Option C, providing diet classes during school hours, may not address the root causes of obesity and could potentially stigmatize the children. Option D, requiring all children to participate in organized team sports, may not be feasible for all children and might not address dietary habits and sedentary behaviors.

Correct Answer: C

Rationale: The term 'social determinants of health' refers to the conditions in which people are born, grow, live, work, and age. This includes factors like socioeconomic status, education, physical environment, employment, and social support networks. These factors have a significant impact on health outcomes. Choices A, B, and D are incorrect because genetic predispositions, lifestyle choices, and access to medical care, although important, are not encompassed by the term 'social determinants of health.'

Correct Answer: C

Rationale: The correct answer is C: Auditory expiratory wheezing. Expiratory wheezing is a common sign of reactive airway disease, such as asthma, where airways are constricted, making it difficult to expel air from the lungs. Choices A, B, and D are incorrect as they are not typically associated with reactive airway disease. Auditory gurgling may suggest airway secretions or fluid accumulation, inspiratory laryngeal stridor indicates upper airway obstruction, and frequent dry coughing is more commonly seen in conditions like upper respiratory infections or postnasal drip.

Correct Answer: C

Rationale: The correct answer is C: Impaired gas exchange. In a client with an acute myocardial infarction, impaired gas exchange is a priority nursing diagnosis due to compromised heart function, which affects oxygenated blood circulation. Close monitoring and interventions are crucial to ensure adequate oxygenation. Choices A, B, and D are incorrect: A) Constipation related to immobility is not the priority in this acute situation; B) High risk for infection is not the immediate concern related to the client's primary diagnosis; D) Fluid volume deficit, while important, is not the priority compared to addressing impaired gas exchange in acute MI.

Correct Answer: C

Rationale: The correct answer is C: 'The stomach contents and air must be drained first.' Before starting feedings through a gastrostomy tube, it is essential to drain the stomach contents and air. This process helps prevent complications and ensures the proper functioning of the tube after placement. Choice A is incorrect because initiating feedings within 5 to 7 days may lead to complications if the stomach is not adequately prepared. Choice B is incorrect as feeding should not begin immediately to allow for proper preparation of the tube and the stomach. Choice D is incorrect because although incision healing is important, draining the stomach contents and air is a more immediate concern to prevent complications.
