The nurse is counseling a young couple who, in 2 months, are having their third baby. The nurse uses Von Bertalanffy's general system theory applied to families to analyze the family structure. Which best describes the main emphasis of this theory and its application to family dynamics?

Correct Answer: A

Rationale: Von Bertalanffy's general system theory applied to families emphasizes the family as a system with interdependent, interacting parts that endure over time to ensure the survival, continuity, and growth of its components. This perspective views the family as a dynamic entity where each member's actions and behaviors impact the overall functioning of the family unit. Choice B is incorrect because it focuses more on the social aspects of family structure rather than the systemic view provided by Von Bertalanffy's theory. Choice C is incorrect as it pertains more to the family life cycle theory, which is different from the general system theory. Choice D is incorrect as it addresses stress response within families, a concept not central to Von Bertalanffy's general system theory.

Correct Answer: C

Rationale: Discussing any other observed behaviors can help identify patterns or potential issues, which is crucial for assessing the infant's overall well-being. Option A about accidents and prevention is not pertinent to the situation described. Option B regarding playtime with other children does not address the infant's behavior and potential causes. Option D about food and vitamins is not relevant to the presented scenario and the observed behavior of the infant.

Correct Answer: A

Rationale: The correct answer is 'On the back, lying flat.' Placing infants on their back to sleep is recommended to reduce the risk of sudden infant death syndrome (SIDS). This position promotes safe sleep practices and helps prevent accidental suffocation. Choices B, C, and D are incorrect as placing infants on their side or with the head slightly elevated may increase the risk of breathing difficulties or other hazards during sleep.

Correct Answer: D

Rationale: In a 3-year-old child presenting with sudden respiratory distress without fever or recent illness, the most likely cause is a foreign body airway obstruction. Foreign body airway obstruction can lead to a sudden onset of respiratory distress as it blocks the air passage. Croup typically presents with a barking cough and stridor, often preceded by a viral illness. Epiglottitis is characterized by high fever, drooling, and a muffled voice. Lower respiratory infections usually present with symptoms such as cough, fever, and chest congestion. Therefore, in this case, the absence of recent illness or fever makes foreign body airway obstruction the most likely cause of the respiratory distress.

Correct Answer: A

Rationale: When a pregnant woman experiences a seizure, it is crucial to transport her on her left side. This position helps to improve blood flow to the fetus by preventing compression of the inferior vena cava, reducing the risk of further complications. Placing her in the prone position (lying face down) or supine position (lying on her back) may compromise blood flow to the fetus and lead to adverse outcomes. Similarly, transporting her in a semi-sitting position may not provide the optimal circulation needed for both the woman and the fetus during this critical situation.
