Correct Answer: C

Rationale: The correct answer is C: Pneumonia. The patient's symptoms of shortness of breath and cough with thick, green sputum suggest an acute infection in the lungs. Pneumonia is characterized by inflammation and infection of the lung tissue, leading to symptoms such as productive cough, shortness of breath, and sputum production. It is a serious condition that requires prompt treatment with antibiotics. A: Asthma typically presents with wheezing, chest tightness, and shortness of breath triggered by certain stimuli, but not usually with thick, green sputum. B: Bronchitis is inflammation of the bronchial tubes, characterized by cough with clear or slightly discolored sputum, not typically thick and green. D: Pulmonary embolism is a blockage in the arteries of the lungs, causing sudden shortness of breath and chest pain, but not usually associated with green sputum production.

Correct Answer: D

Rationale: The correct answer is D because the presence of a physical characteristic like a scar is an objective finding that can be directly observed and measured during a physical assessment. This information is not subject to interpretation or bias. In contrast, choices A, B, and C involve subjective information that relies on the patient's report or memory, making them less reliable and objective. History of allergies (A) and use of medications (B) are subjective and based on the patient's self-report, while last menstrual period (C) is also subjective and may not always be accurate. Therefore, choice D is the only objective piece of information among the options provided.

Correct Answer: A

Rationale: The correct answer is A because all aspects of mental health in children are indeed interrelated. Mental health encompasses various components such as emotional, social, and psychological well-being, which are interconnected and influence each other. Understanding and assessing mental health in children require considering the holistic picture. Choice B is incorrect because children are not inherently labile and unstable until the age of 2 years. Choice C is incorrect as children's mental health is influenced by various factors beyond just their parents' mental health. Choice D is incorrect because mental health assessment in children can be done using age-appropriate methods even before they develop the ability to concentrate.

Correct Answer: A

Rationale: The correct answer is A: Crossing the legs at the knees. This position can cause hip dislocation due to the twisting motion it creates on the hip joint. When the legs are crossed at the knees, it puts stress on the hip joint, potentially leading to dislocation. Choice B: Sitting with the feet flat on the floor is a safe position that does not put undue stress on the hip joint. Choice C: Sleeping on the affected side can also increase the risk of hip dislocation due to the pressure and weight placed on the hip joint in this position. Choice D: Using assistive devices for ambulation is important for stability and support, and it does not directly contribute to hip dislocation if used correctly.

Correct Answer: A

Rationale: The correct answer is A because in Vietnamese culture, touching or examining the fontanelles (soft spots on a baby's head) is considered disrespectful and potentially harmful. This is due to the belief that the fontanelles are fragile and touching them can impact the baby's health. It is crucial for the nurse to respect and be sensitive to the cultural beliefs and practices of the mother to establish trust and provide culturally competent care. Choice B is incorrect because there is no specific cultural taboo in Vietnamese culture about touching the infant's diaper area during examination. Choice C is incorrect as assuming that the husband should be the primary communicator of medical information goes against the principle of patient autonomy. Choice D is incorrect as there is no indication that Vietnamese mothers prefer written reports over verbal communication regarding their child's growth and development.
