Correct Answer: B

Rationale: The correct answer is B: “Have you strained your voice recently?” This question is relevant to the client's symptom of hopeless, as vocal strain can contribute to this issue. Asking about voice strain helps to identify a potential cause and guides further assessment and intervention. Choice A is not directly related to the client's primary concern and does not address the underlying cause of hopeless. Choice C is unrelated to the client's symptom and does not provide information that is pertinent to addressing the issue at hand. Choice D is also unrelated to the client's symptom of hopeless and does not address potential contributing factors.

Correct Answer: B

Rationale: The correct answer is B: Dyspnea on exertion. In older clients, dyspnea on exertion is often the earliest symptom of heart failure due to decreased cardiac reserve. This occurs when the heart cannot pump enough blood to meet the body's demands during physical activity. Increased urine output (A) is not typically an early symptom of heart failure. Swollen joints (C) are more indicative of arthritis or inflammation, not necessarily heart failure. Nausea and vomiting (D) are not typical early symptoms of heart failure and are more commonly associated with gastrointestinal issues.

Correct Answer: A

Rationale: The correct answer is A because the Nursing Interventions Classification (NIC) system is not designed to help medical students determine the cost of care. The NIC system focuses on standardizing and categorizing nursing interventions to improve communication, documentation, and patient care. Choice B is incorrect because it correctly identifies one of the benefits of using the NIC system - enhancing communication among nurses. Choice C is incorrect because it suggests a valid use of the NIC system for organizing orientation and explaining nursing interventions. Choice D is incorrect because it accurately states that the NIC system can improve documentation in the electronic health record, which is one of its purposes.

Correct Answer: C

Rationale: The correct answer is C because compatibility between blood donor and recipient is determined by the absence of clumping or hemolysis when both samples are mixed. Clumping indicates an incompatible blood type reaction, leading to potential harm. Blood clots (option B) are not indicative of compatibility but rather a sign of coagulation issues. Blood color change (option A) and blood drop sinking in water (option D) are not reliable indicators of blood compatibility. In summary, option C is correct as it directly assesses for the absence of a harmful reaction, while the other choices do not accurately determine blood compatibility.

Correct Answer: B

Rationale: The correct answer is B: Washing the hands frequently. This is important for preventing the spread of infection, which is crucial in acute bronchitis. By washing hands frequently, the client can reduce the risk of transmitting the infection to others and prevent reinfection. A: Not coughing frequently - While managing cough is important, it is not the most crucial aspect in the teaching plan for acute bronchitis. C: Consuming adequate calories - While nutrition is important for overall health, it is not specifically related to the management of acute bronchitis. D: Encouraging a semi-Fowler’s position - While this position can help with breathing, it is not the most important aspect in the teaching plan for acute bronchitis.
