ATI RN Custom Exams Set 5
1. The nurse is aware that norepinephrine is secreted by which endocrine gland?
- A. The pancreas
- B. The adrenal cortex
- C. The adrenal medulla
- D. The anterior pituitary gland
Correct answer: C
Rationale: Norepinephrine is indeed secreted by the adrenal medulla, making choice C the correct answer. The adrenal medulla is part of the adrenal glands, located on top of the kidneys. Norepinephrine is involved in the body's 'fight or flight' response, helping to prepare the body to react to stress. Choices A, B, and D are incorrect as norepinephrine is not secreted by the pancreas, adrenal cortex, or the anterior pituitary gland.
2. What client is a susceptible host most at risk for infection?
- A. A client with leukemia
- B. A hospitalized 35-year-old-client
- C. A child who is immunized
- D. A 60-year-old client
Correct answer: A client with leukemia
Rationale:
3. A 54-year-old has a diagnosis of breast cancer and is tearfully discussing her diagnosis with the nurse. The patient states, 'They tell me my cancer is malignant, while my coworker's breast tumor was benign. I just don't understand at all.' When preparing a response to this patient, the nurse should be cognizant of what characteristic that distinguishes malignant cells from benign cells of the same tissue type?
- A. Slow rate of mitosis of cancer cells
- B. Different proteins in the cell membrane
- C. Differing size of the cells
- D. Different molecular structure in the cells
Correct answer: B
Rationale: The correct answer is B. Malignant cells have different proteins in their membranes, such as tumor-specific antigens, which distinguish them from benign cells. Choice A is incorrect as cancer cells typically have a rapid and uncontrolled rate of mitosis. Choice C is incorrect as the size of cells alone does not distinguish between malignant and benign cells. Choice D is incorrect as the molecular structure is not the primary characteristic that distinguishes between malignant and benign cells.
4. Which lab value is most critical to monitor in a patient receiving digoxin?
- A. Monitor potassium levels
- B. Monitor sodium levels
- C. Monitor calcium levels
- D. Monitor magnesium levels
Correct answer: A
Rationale: The correct answer is to monitor potassium levels in a patient receiving digoxin. Hypokalemia can potentiate the toxic effects of digoxin, leading to serious cardiac arrhythmias. Monitoring potassium levels helps prevent toxicity. Monitoring sodium levels (Choice B), calcium levels (Choice C), and magnesium levels (Choice D) are also important aspects of patient care, but potassium levels are most critical in patients on digoxin therapy.
5. Which of the following foods provides the most protein?
- A. Beans
- B. Red peppers
- C. Asparagus
- D. Celery
Correct answer: A
Rationale: The correct answer is 'Beans.' Beans are a rich source of plant-based protein, making them the best option among the listed foods for protein content. Red peppers, asparagus, and celery are not significant sources of protein compared to beans, hence they are incorrect choices for this question.
