Correct Answer: B

Rationale: The correct answer is B: Use two people to assist the patient. This is the safest option as it provides optimal support and stability for the patient during their first postoperative ambulation. Two people can help prevent falls, ensure proper body mechanics, and offer immediate assistance if needed. Using one person (choice A) may not provide enough support. Encouraging the patient to "dangle" (choice C) may increase the risk of orthostatic hypotension. Giving a narcotic before ambulation (choice D) can impair the patient's balance and coordination, increasing the risk of falls.

Correct Answer: B

Rationale: The correct answer is B: Disturbed body image. The client expressing concern about the external fixation device making his leg look ugly indicates a disturbance in how he perceives his body image. This can lead to feelings of low self-esteem and impact his overall psychological well-being. Impaired physical mobility (A) is not the priority as the concern is not related to limitations in movement. Risk for infection (C) may be a potential risk with the device but is not directly related to the client's current concern. Risk for social isolation (D) is not directly indicated by the client's statement about the appearance of the leg. Therefore, the most appropriate nursing diagnosis is Disturbed body image (B) based on the client's expressed concern.

Correct Answer: B

Rationale: Step 1: Antibiotics are prescribed to treat urethritis, indicating a bacterial infection in the urinary tract. Step 2: Increasing water intake (2-3 L daily) promotes renal blood flow, dilutes urine, and helps flush out bacteria from the urinary tract, aiding in the elimination of infection. Step 3: Adequate hydration helps prevent the formation of concentrated urine, reducing the risk of recurrent urinary tract infections. Step 4: Therefore, choice B is correct as it directly addresses the underlying cause of the client's symptoms. Summary: Choices A, C, and D are incorrect as they do not directly target the bacterial infection causing the urinary discomfort. Drinking water will not specifically help with incontinence, eliminate odors, or provide pain relief.

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 because the problem-oriented approach involves focusing on the patient's presenting situation to identify the main issues and prioritize data collection. This step helps the nurse understand the immediate concerns and sets the direction for further assessment and interventions. Choice A is incorrect because completing questions in chronological order may not address the most urgent issues. Choice C is incorrect as accurate interpretations come after collecting relevant data. Choice D is incorrect as conducting an observational overview is part of the assessment process but not the first step in the problem-oriented approach.
