Correct Answer: D

Rationale: The correct answer is D because educating the client about the disease process and its limitations is crucial in managing Chronic Fatigue Syndrome (CFS). By understanding the disease, the client can make informed decisions regarding their lifestyle, activities, and self-care. This empowers the client to manage symptoms effectively and prevent exacerbations. Choice A is not the most important factor as simply avoiding aggravating the disease does not address the overall management of CFS. Choice B focuses solely on drug therapy, which is only one aspect of the client's management and may not provide significant improvement for all clients with CFS. Choice C, altering diet and environment, can be helpful but may not be the most important factor as understanding the disease process and limitations is essential for long-term management and quality of life.

Correct Answer: B

Rationale: The correct answer is B because during the evaluation phase of nursing care for a client with COPD, the nurse should review the client's progress toward meeting the goals set during the planning phase. This involves assessing whether the interventions implemented are effective in improving the client's condition and if the goals are being achieved. This step is crucial in determining the overall effectiveness of the care provided and making any necessary adjustments to the plan. A: Documenting interventions is important but not the primary focus during the evaluation phase. C: Delegating further care is not typically done during the evaluation phase as it is more about assessing the current care plan. D: Ensuring compliance with physician orders is important but does not encompass the holistic evaluation of the client's progress towards goals.

Correct Answer: A

Rationale: The correct answer is A. First, the nurse should assess the chest-drainage system and tubing for any air leaks. Air leaks can cause bubbling in the water-seal chamber, indicating a potential issue with the system's integrity. By examining the entire system, the nurse can identify and correct any leaks to ensure proper functioning of the chest-drainage system. Lowering the level of suction (choice B) may not address the underlying issue of air leaks. Doing nothing (choice C) is not appropriate as vigorous bubbling indicates a problem. Asking the patient to cough forcefully (choice D) is unrelated to addressing bubbling in the water-seal chamber.

Correct Answer: C

Rationale: The correct answer is C: Confusion. Hypernatremia is an electrolyte imbalance characterized by high sodium levels in the blood. Confusion is a common symptom as high sodium levels can affect brain function. Dry skin (A) is more indicative of dehydration, tachycardia (B) is a symptom of various conditions, and pale coloring (D) is not specific to hypernatremia. Confusion is a key indicator that the nurse should assess for when monitoring for hypernatremia.

Correct Answer: B

Rationale: The correct answer is B: A latex condom with spermicide provides the best protection against HIV transmission during sexual intercourse. Rationale: 1. Latex condoms create a physical barrier that helps prevent the exchange of bodily fluids containing HIV. 2. Spermicide can further reduce the risk of HIV transmission by killing some viruses and bacteria. 3. Research shows that consistent and correct use of condoms is highly effective in reducing the risk of HIV transmission. 4. Other choices are incorrect: - A: Unprotected sex between HIV-positive individuals can lead to the transmission of drug-resistant strains or different strains of HIV. - C: Contraceptive methods like birth control pills do not protect against HIV transmission. - D: The intrauterine device is not specifically recommended for clients with HIV due to potential risks of infection.
