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: B

Rationale: Rationale: B is correct because patients with CKD often have difficulty excreting potassium, so limiting high potassium foods is crucial to prevent hyperkalemia. A is incorrect because increasing potassium intake is not recommended. C is incorrect as excessive protein intake can worsen kidney function. D is incorrect because CKD patients typically have fluid restrictions to prevent fluid overload and electrolyte imbalances.

Correct Answer: B

Rationale: The correct answer is B: Encouraging early ambulation. This is crucial post-total hip replacement to prevent complications such as blood clots, pneumonia, and muscle weakness. Early ambulation helps improve circulation, prevent stiffness, and promote faster recovery. Monitoring for infection (A) is important but not the top priority. Administering pain medications (C) and wound care (D) are essential but do not address the primary goal of preventing complications post-operatively.

Correct Answer: B

Rationale: The correct answer is B: Encouraging early ambulation. Early ambulation helps prevent complications such as blood clots, improves circulation, aids in lung expansion, and promotes faster recovery. Pain management is important but encouraging mobility is a priority. Administering IV antibiotics is not necessary unless there is an infection present. Monitoring for signs of deep vein thrombosis is important but encouraging ambulation is a proactive approach to prevent its occurrence.

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.
