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. When auscultating the patient's lungs during a shift assessment on a patient admitted in the early phase of heart failure, which finding would the nurse most likely hear?
- A. Continuous rumbling, snoring, or rattling sounds mainly on expiration
- B. Continuous high-pitched musical sounds on inspiration and expiration
- C. Discontinuous, high-pitched sounds of short duration heard on inspiration
- D. A series of long-duration, discontinuous, low-pitched sounds during inspiration
Correct answer: C
Rationale: In the early phase of heart failure, fine crackles are likely to be heard upon auscultation of the lungs. Fine crackles are characterized as discontinuous, high-pitched sounds of short duration heard on inspiration. Rhonchi are continuous rumbling, snoring, or rattling sounds mainly on expiration, which are often associated with airway secretions. Coarse crackles are a series of long-duration, discontinuous, low-pitched sounds during inspiration, typically indicating fluid in the alveoli. Wheezes are continuous high-pitched musical sounds on inspiration and expiration, commonly heard in conditions like asthma or chronic obstructive pulmonary disease (COPD). Therefore, the correct choice is C, as it describes the expected lung sounds in a patient with early heart failure.
3. When caring for a patient hospitalized with active tuberculosis (TB), the nurse observes a student nurse who is assigned to take care of the patient. Which action, if performed by the student nurse, would require an intervention by the nurse?
- A. The patient is offered a tissue from the box at the bedside.
- B. A surgical face mask is applied before visiting the patient.
- C. A snack is brought to the patient from the unit refrigerator.
- D. Hand washing is performed before entering the patient's room.
Correct answer: B
Rationale: When caring for a patient with active tuberculosis (TB), it is crucial to use a high-efficiency particulate-absorbing (HEPA) mask instead of a standard surgical mask when entering the patient's room, as a HEPA mask can filter out 100% of small airborne particles, reducing the risk of transmission. Therefore, if the student nurse applies only a surgical face mask before visiting the patient, this action would require intervention by the nurse to ensure the appropriate protective equipment is used. Hand washing before entering the patient's room is essential to prevent the spread of infection and is a correct action. Bringing a snack to the patient from the unit refrigerator is appropriate and helps address potential issues with anorexia and weight loss in patients with TB. While hand washing after handling a tissue used by the patient is necessary, no special precautions are required when offering the patient an unused tissue.
4. The nurse plans health care for a community with a large number of recent immigrants from Vietnam. Which intervention is the most important for the nurse to implement?
- A. Hepatitis testing
- B. Tuberculosis screening
- C. Contraceptive teaching
- D. Colonoscopy information
Correct answer: B
Rationale: Tuberculosis (TB) is prevalent in many parts of Asia, including Vietnam, and the incidence of TB is higher in immigrants from Vietnam compared to the general U.S. population. Conducting tuberculosis screening is crucial to identify and address any cases promptly, especially in a community with recent immigrants from Vietnam. While teaching about contraceptive use, providing colonoscopy information, and testing for hepatitis may be relevant for certain individuals in the community, they are not as universally important as tuberculosis screening due to the increased risk of TB among Vietnamese immigrants.
5. 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.
