Correct Answer: C

Rationale: The correct answer is C: 5 years. In ALS, 50% of patients have a life expectancy of around 3-5 years from the time of diagnosis. This is due to the progressive nature of the disease, leading to rapid deterioration of motor neurons and muscle function. Choice A (3 years) is too specific and may not apply to exactly 50% of patients. Choice B (10 years) and D (20 years) are too optimistic and do not align with the typical prognosis of ALS, where the majority of patients have a shorter life expectancy. Therefore, based on the average survival rates and disease progression, choice C is the most accurate representation of the normal life expectancy for 50% of ALS patients.

Correct Answer: B

Rationale: The correct answer is B: Resolve the client’s anxiety. Addressing the client's anxiety is the priority because it can impact their overall surgical experience, recovery, and outcomes. Resolving anxiety can improve the client's emotional well-being, enhance cooperation during surgery, and reduce postoperative complications related to stress. Providing emotional support and reassurance should be the initial focus to help the client feel more comfortable and confident about the upcoming surgery. The other choices are not the priority in this situation: A) Evaluating the need for antibiotics can be addressed later in the preoperative process, C) Providing preoperative education is important but not the immediate priority over addressing anxiety, and D) Preparing the client for surgery includes various components, but emotional well-being should be addressed first.

Correct Answer: C

Rationale: The correct answer is C: Autonomy. Autonomy is the ethical principle that upholds an individual's right to make decisions about their own healthcare. In this scenario, the client is expressing her desire to not undergo surgery, which is her right as an autonomous individual. The nurse must respect her decision even if it goes against medical advice. Beneficence (A) is the ethical principle of doing good for the patient, but in this case, respecting the client's autonomy takes precedence. Advocacy (B) involves supporting the client's best interests, which could align with autonomy in this case. Justice (D) refers to fairness and equal treatment, but it is not directly applicable to the client's decision regarding surgery.

Correct Answer: A

Rationale: The correct answer is A: Pneumocystis carinii pneumonia (PCP). PCP is the most common opportunistic infection in AIDS due to the weakened immune system, making patients vulnerable to this fungal infection. PCP is a leading cause of morbidity and mortality in AIDS patients. Toxoplasmosis (B) is also common but not as prevalent as PCP in AIDS. Candidiasis (C) is a common fungal infection but not the most common in AIDS. Mycoplasma pneumoniae (D) is a bacterial infection and not typically considered an opportunistic infection in AIDS.

Correct Answer: C

Rationale: The correct answer is C: Implementation. In this step of the nursing process, the nurse is carrying out the care plan based on the identified nursing diagnoses. The nurse is actively providing care and interventions to meet the patient's needs. Assessment (A) is the initial step where data is collected and analyzed. Planning (B) is where goals and interventions are determined based on assessment findings. Evaluation (D) is the final step where the nurse assesses the effectiveness of the care provided. In this scenario, the nurse has already completed the care plan and is now executing the plan by implementing the interventions, making choice C the correct answer.
