Question 1 of 5

The nurse knows which of the following is true about immunity?

Correct Answer: C

Rationale: Rationale: Choice C is correct because antibodies are indeed produced by B-cells as part of the adaptive immune response. B-cells differentiate into plasma cells that produce antibodies to target specific antigens. This process is essential for generating immunity against pathogens. Incorrect Choices: A: Antibody-mediated defense occurs through the B-cell system, not the T-cell system. T-cells are involved in cell-mediated immunity. B: Cellular immunity is mediated by T-cells, not antibodies produced by B-cells. T-cells directly attack infected cells. D: Lymphocytes can increase during an allergic response, but this does not specifically relate to immunity through antibody production by B-cells.

Question 2 of 5

The normal life expectancy for 50% of patients ith amyotropic lateral sclerosis (ALS) is:

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.

Question 3 of 5

Rehabilitation plans for Mr. Gabatan;

Correct Answer: B

Rationale: Rationale for Correct Answer B: Rehabilitation plans for Mr. Gabatan should be considered and planned for early in his care to optimize his recovery and quality of life. Planning early allows for tailored interventions to address his specific needs and goals, promoting better outcomes. Early rehabilitation can also prevent complications and improve functional abilities. By proactively addressing rehabilitation needs, Mr. Gabatan can have a smoother transition back to his daily activities. Summary of Incorrect Choices: A: Leaving the rehabilitation plans solely up to Mr. Gabatan and his family may not consider all aspects of his recovery and could lead to suboptimal outcomes. C: Assuming that Mr. Gabatan will return to his former activities without a rehabilitation plan overlooks the individualized care needed for his recovery. D: Dismissing the need for rehabilitation based on the assumption that he may not be able to work again is premature and does not account for potential improvements in his condition through appropriate rehabilitation interventions.

Question 4 of 5

Which of the following statements would be most appropriate when assisting a patient who has the nursing diagnosis ofAltered Thought Process with Persona! Hygiene Needs?

Correct Answer: D

Rationale: Rationale: - Choice D is correct as it offers the patient autonomy and promotes self-care, which is important for maintaining independence and dignity. - By giving the patient a choice between brushing their own teeth or having assistance, it empowers them to make decisions. - Choices A, B, and C are not as appropriate because they do not address the patient's autonomy and may come across as directive or intrusive, which can further exacerbate the altered thought process.

Question 5 of 5

Which part of the body is supplied by nerves form the thoracic cord?

Correct Answer: C

Rationale: The correct answer is C: Trunk. The thoracic cord supplies nerves to the trunk region of the body. The thoracic spinal nerves innervate the chest, abdomen, and back. They control sensation and movement in these areas. The head (A) is mainly supplied by cranial nerves, the pelvis (B) is innervated by lumbar and sacral nerves, and the coccyx (D) is supplied by the sacral nerves. Therefore, the correct answer is C as it aligns with the anatomical distribution of the thoracic spinal nerves.
