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

Correct Answer: A

Rationale: The correct answer is A because electrolytes help maintain normal fluid balance in the body by regulating fluid levels inside and outside cells, enabling proper nerve and muscle function. Choice B is incorrect because electrolytes are not related to nutritional intake. Choice C is incorrect as electrolytes do not directly affect absorption of nutrients. Choice D is incorrect as electrolytes do not play a role in elimination processes. Maintaining normal fluid balance is crucial for overall health and electrolytes play a vital role in achieving this balance.

Correct Answer: A

Rationale: The correct answer is A: Unstable angina. Unstable angina occurs when there is a sudden disruption in a coronary artery, leading to reduced blood flow to the heart even at rest. This is a medical emergency as it can progress to a heart attack. Orthopnea (B) is a condition where individuals experience difficulty breathing while lying down. Ischemia (C) refers to inadequate blood supply to an organ, which can lead to angina but does not specify the rest state. Stable angina (D) occurs during physical exertion or stress, not at rest.

Correct Answer: C

Rationale: The correct answer is C because a non-weight bearing order indicates that the resident is unable to touch the floor with either leg. This means the resident must not put any weight on their legs while standing or walking. Choices A, B, and D all involve some level of weight-bearing, which contradicts the concept of non-weight bearing. Therefore, they are incorrect options.

Correct Answer: C

Rationale: The correct answer is C: Reminiscence therapy. This form of therapy focuses on recalling past experiences to promote emotional healing and self-understanding. It can help individuals process unresolved emotions and gain insight into their behaviors. Reality orientation (A) aims to help individuals with cognitive impairments stay connected to the present. Validating (B) involves acknowledging and accepting a person's feelings and experiences. Remotivation therapy (D) focuses on restoring motivation and self-esteem through goal-setting and encouragement. Reminiscence therapy is specifically designed to explore and reflect on past memories for therapeutic benefit.

Correct Answer: B

Rationale: The correct answer is B: Palliative care. Palliative care focuses on relieving symptoms and managing pain for individuals with cancer, improving their quality of life. It is not irreversible (A), as it can be adjusted based on the patient's needs. It is also not generalized (C) but rather tailored to each individual's specific symptoms. While empathy is important in healthcare, being empathetic (D) alone does not directly address symptom relief and pain management.
