Correct Answer: C

Rationale: Family systems theory views the family as an interconnected system where changes in one member affect the entire family, making it ideal for assessing group dynamics.

Correct Answer: B

Rationale: The correct answer is 'Disease prevention.' Modern healthcare places emphasis on preventing diseases to enhance overall health and well-being. While nursing services, symptom management, and disease identification are crucial components of healthcare, disease prevention plays a key role in reducing the burden of illness on individuals and communities.

Correct Answer: B

Rationale: The correct answer is B: Stress the importance of early infant stimulation and intervention programs. Early intervention programs are essential for infants with developmental disabilities as they can significantly impact the child's development and future outcomes. These programs provide necessary support and therapies to enhance the child's skills and abilities. Choice A is incorrect because it is crucial to provide hope and support to parents, emphasizing the potential for development and progress. Choice C is inappropriate and unethical as the first line of intervention. Institutionalization should only be considered in extreme cases where other options have been exhausted. Choice D is not the most crucial intervention at this stage. While reevaluation may be necessary, early intervention and support should be prioritized to maximize the child's developmental potential.

Correct Answer: A

Rationale: The correct answer is A: Cephalocaudal. The cephalocaudal pattern of development means that growth and motor control proceed from the head downward through the body. This explains why infants can raise their heads before they can sit and gain control of their trunks before walking. Choices B, C, and D are incorrect. Anterior to posterior refers to development from the front to the back, while proximodistal refers to development from the center of the body outward. Normal growth curve charts are used to track physical growth over time and are not directly related to the directional pattern of development in infants.

Correct Answer: C

Rationale: The sweat chloride test is the primary diagnostic test for cystic fibrosis. Cystic fibrosis is characterized by abnormal transport of chloride and sodium across epithelial cell membranes, leading to increased chloride in sweat. This test is crucial for diagnosing cystic fibrosis in suspected cases. Liver enzymes (Choice A), serum calcium (Choice B), and urine creatinine (Choice D) are not specific tests for cystic fibrosis and would not provide the necessary information for diagnosis in this case.
