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 asks the nurse whether he is a good candidate to use a CPAP machine. The nurse reviews the client's history. Which condition would contraindicate the use of a CPAP machine?
- A. The patient is in the late stage of dementia.
- B. The patient has a history of bronchitis.
- C. The patient has had suicidal gestures/attempts in the past.
- D. The patient is on beta-blockers.
Correct answer: A
Rationale: The correct answer is that the patient is in the late stage of dementia. In late-stage dementia, individuals may have an inability to follow commands and understand instructions independently, which are essential for proper installation and use of a CPAP machine. This makes using a CPAP machine challenging and potentially ineffective for patients in this condition. Choice B, having a history of bronchitis, does not contraindicate the use of a CPAP machine. In fact, CPAP therapy can be beneficial for patients with respiratory conditions like bronchitis. Choice C, a history of suicidal gestures/attempts, while concerning for the patient's mental health, does not directly contraindicate the use of a CPAP machine. Choice D, being on beta-blockers, is not a contraindication for CPAP machine use. Beta-blockers are commonly used medications for various conditions and do not interfere with the use of a CPAP machine.
3. A child is diagnosed with Hirschsprung's disease. The nurse is teaching the parents about the cause of the disease. Which statement, if made by the parent, supports that teaching was successful?
- A. The absence of special cells in the rectum caused the disease.
- B. Incomplete digestion of the protein part of wheat, barley, rye, and oats is not the cause of the disease.
- C. The disease does not occur due to increased bowel motility leading to spasm and pain.
- D. The disease is not caused by the inability to tolerate sugar found in dairy products.
Correct answer: A
Rationale: Hirschsprung's disease, also known as congenital aganglionosis or megacolon, is characterized by the absence of ganglion cells in the rectum and, sometimes, extending into the colon. Choice A correctly explains the cause of Hirschsprung's disease. Choice B is incorrect as it describes celiac disease, which is related to gluten intolerance. Choice C is inaccurate as it describes symptoms of irritable bowel syndrome, not the cause of Hirschsprung's disease. Choice D is wrong as it pertains to lactose intolerance, not Hirschsprung's disease.
4. A teen patient is admitted to the hospital by his physician who suspects a diagnosis of acute glomerulonephritis. Which of the following findings is consistent with this diagnosis? Select one that doesn't apply.
- A. Urine specific gravity of 1.040.
- B. Urine output of 350 ml in 24 hours.
- C. Brown ("tea-colored"?) urine.
- D. Generalized edema.
Correct answer: D
Rationale: The correct answer is 'Generalized edema.' Acute glomerulonephritis typically presents with periorbital edema, not generalized edema. Findings in acute glomerulonephritis include dark, smoky, or tea-colored urine (hematuria) due to red blood cells in the urine, elevated blood pressure, and proteinuria. The urine specific gravity may be high due to decreased urine output, but a urine output of 350 ml in 24 hours is extremely low and suggestive of renal impairment. Generalized edema is more commonly associated with nephrotic syndrome, where there is significant proteinuria leading to hypoalbuminemia and subsequent fluid retention in tissues. In acute glomerulonephritis, the edema is usually limited to the face and lower extremities, not generalized.
5. A client with schizophrenia is receiving Haloperidol (Haldol) 5 mg t.i.d.. The client's family is alarmed and calls the clinic when 'his eyes rolled upward.' The nurse recognizes this as what type of side effect?
- A. Oculogyric crisis
- B. Tardive dyskinesia
- C. Nystagmus
- D. Dysphagia
Correct answer: A
Rationale: Oculogyric crisis is a known side effect of antipsychotic medications like Haloperidol (Haldol) and is characterized by involuntary upward deviation of the eyes. This condition can be distressing to both the client and their family. Tardive dyskinesia (Choice B) is a different side effect characterized by repetitive, involuntary movements, especially of the face and tongue, which can occur with long-term antipsychotic use. Nystagmus (Choice C) is an involuntary eye movement that is rhythmic and can occur for various reasons but is not specific to Haloperidol use. Dysphagia (Choice D) refers to difficulty swallowing and is not typically associated with the use of Haloperidol.
