Electrolytes are chemical substances essential to maintaining _________ in the body.

Correct Answer: A

Rationale: The correct answer is A: Normal fluid balance. Electrolytes are essential for maintaining proper fluid balance in the body by regulating water movement across cell membranes. They help with nerve function, muscle contraction, and maintaining pH levels. Choice B, suitable nutritional intake, is incorrect as electrolytes are not related to dietary intake. Choice C, proper absorption, is incorrect as electrolytes do not directly aid in absorption. Choice D, adequate elimination, is incorrect as electrolytes do not play a direct role in elimination processes.

Correct Answer: A

Rationale: The correct answer is A: Unstable angina. Unstable angina occurs at rest due to the narrowing of coronary arteries leading to reduced blood flow to the heart. This can result in chest pain or discomfort even without physical exertion. Orthopnea (B) is difficulty breathing when lying down. Ischemia (C) refers to inadequate blood supply to tissues. Stable angina (D) typically occurs during physical activity due to predictable triggers. Unstable angina is the only form that occurs at rest, making it the correct choice.

Correct Answer: C

Rationale: The correct answer is C because a non-weight bearing order means the resident is unable to touch the floor with either leg. This indicates complete restriction of weight-bearing on the lower extremities. Choices A, B, and D all involve some form of weight-bearing ability, which contradicts the concept of non-weight bearing. Thus, C is the only option that aligns with the definition of a non-weight bearing order.

Correct Answer: C

Rationale: The correct answer is C: Reminiscence therapy. This form of therapy encourages individuals, especially older adults, to remember past experiences as a way to promote emotional well-being and cognitive function. It helps individuals reflect on significant life events, fostering a sense of identity and self-worth. A: Reality orientation focuses on helping individuals with cognitive impairments stay oriented to the present time, place, and person. B: Validating refers to acknowledging and accepting a person's thoughts and feelings without judgment, but it does not specifically involve recalling past experiences. D: Remotivation therapy aims to motivate individuals to engage in meaningful activities but does not specifically target remembering past experiences.

This type of care is not aimed at curing the disease but rather at improving comfort and overall well-being. Incorrect options: A: Irreversible - This term does not relate to the type of care provided for cancer patients. C: Generalized - This term does not specify the specialized care needed for managing cancer symptoms. D: Empathetic - While empathy is important in healthcare, it does not specifically address the type of care required for symptom relief in cancer patients.
