NCLEX RN Exam Review Answers
1. A patient scheduled for cataract surgery asks the nurse why they developed cataracts and how to prevent it in the future. What is the nurse's best response?
- A. Age is the biggest factor contributing to cataracts.
- B. Unprotected exposure to UV lights can cause cataracts.
- C. Age, eye injury, corticosteroids, and unprotected sunlight exposure are contributing factors to cataracts.
- D. Unfortunately, there is really nothing you can do to prevent cataracts, but they are amongst the most easily treated eye conditions.
Correct answer: C
Rationale: The correct answer is C: 'Age, eye injury, corticosteroids, and unprotected sunlight exposure are contributing factors to cataracts.' This response is the best choice as it covers the most common contributing factors for cataracts and includes preventable risk factors. Choice A is incorrect because while age is a significant factor in cataract development, it is not the only one. Choice B is incorrect as UV light exposure is a risk factor for cataracts but not the most comprehensive response. Choice D is incorrect as there are preventive measures individuals can take to reduce their risk of developing cataracts, such as protecting their eyes from UV light and managing other risk factors.
2. A patient is undergoing a stress test on a treadmill and turns to talk to the nurse. Which of these statements would require the most immediate intervention?
- A. I'm feeling extremely thirsty and will get some water after this.
- B. I can feel my heart racing.
- C. My shoulder and arm are hurting.
- D. My blood pressure reading is 158/80
Correct answer: C
Rationale: The correct answer is 'C: My shoulder and arm are hurting.' Unilateral arm and shoulder pain are classic symptoms of myocardial ischemia, indicating possible heart issues. In this scenario, immediate intervention is required, and the stress test should be halted. Choice A about feeling thirsty does not indicate an acute medical issue. Choice B mentioning heart racing is expected during a stress test. Choice D, a blood pressure reading of 158/80, while slightly elevated, does not present an immediate concern compared to the symptoms of arm and shoulder pain suggesting cardiac distress.
3. A 1-year-old child is diagnosed with intussusception, and the mother of the child asks the student nurse to describe the disorder. Which statement by the student nurse indicates correct understanding of this disorder?
- A. It is an acute bowel obstruction.
- B. It is a condition that causes an acute inflammatory process in the bowel.
- C. It is a condition in which a distal segment of the bowel prolapses into a proximal segment of the bowel.
- D. It is a condition in which a proximal segment of the bowel prolapses into a distal segment of the bowel.
Correct answer: D
Rationale: Intussusception is a condition in which a proximal segment of the bowel telescopes or prolapses into a distal segment of the bowel. This leads to bowel obstruction and potential ischemia. It is not an acute bowel obstruction, as the obstruction is caused by the telescoping of bowel segments rather than a blockage in the bowel lumen. Intussusception is not primarily an inflammatory process; instead, it is a mechanical issue involving bowel invagination. Choice A is incorrect as it does not accurately describe the pathophysiology of intussusception. Choice C is incorrect because it presents the opposite scenario of what happens in intussusception.
4. A nurse is caring for an infant who has recently been diagnosed with a congenital heart defect. Which of the following clinical signs would most likely be present?
- A. Slow pulse rate
- B. Weight gain
- C. Decreased systolic pressure
- D. Irregular WBC lab values
Correct answer: B
Rationale: Weight gain due to fluid accumulation is associated with heart failure and congenital heart defects. When the heart is unable to circulate blood normally, the kidneys receive less blood, leading to reduced fluid filtration into the urine. The excess fluid accumulates in various body parts such as the lungs, liver, eyes, and sometimes in the legs. Slow pulse rate (Choice A) is less likely as infants with heart failure typically present with tachycardia due to the body compensating for decreased cardiac output. Decreased systolic pressure (Choice C) is also less likely as heart failure typically leads to increased blood pressure as the body tries to maintain adequate perfusion. Irregular white blood cell (WBC) values (Choice D) are not directly associated with congenital heart defects unless there is an underlying infection or inflammatory process.
5. Based on Mr. C's assessment, which of the following nursing interventions is most appropriate?
- A. Elevate the lower extremities to 45 degrees to promote venous return
- B. Place Mr. C in the Trendelenburg position
- C. Administer total parenteral nutrition
- D. Monitor urine output
Correct answer: D
Rationale: In the context of Mr. C's assessment, the most appropriate nursing intervention is to monitor urine output. A client in hypovolemic shock may experience decreased urine output due to poor kidney perfusion. By monitoring urine output, the nurse can assess renal function and fluid status. Administering total parenteral nutrition (Choice C) is not indicated based on the information provided, as the priority is to stabilize the client's condition. Elevating the lower extremities (Choice A) may be helpful in some cases but is not the priority in this situation. Placing Mr. C in the Trendelenburg position (Choice B) is contraindicated in hypovolemic shock as it can worsen venous return and compromise cardiac output.
