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 nurse is caring for a patient admitted to the emergency room for an ischemic stroke with marked functional deficits. The physician is considering the use of fibrinolytic therapy with TPA (tissue plasminogen activator). Which history-gathering question would not be important for the nurse to ask?
- A. What time did you first notice symptoms consistently appearing?
- B. Have you been taking any blood thinners such as heparin, lovenox, or warfarin?
- C. Have you had another stroke or head trauma in the previous 3 months?
- D. Have you had any blood transfusions within the previous year?
Correct answer: D
Rationale: The correct answer is 'Have you had any blood transfusions within the previous year?' This question is not relevant in the context of considering fibrinolytic therapy with TPA for an ischemic stroke. Blood transfusions within the previous year do not directly impact the decision to use TPA in the treatment of an acute ischemic stroke. The focus should be on factors such as the time of symptom onset, current medications like blood thinners, and recent history of strokes or head trauma, as these are more directly related to the decision-making process for administering TPA in this emergency situation.
3. A 25-year-old male client has been newly diagnosed with hypothyroidism and will take levothyroxine (Synthroid) 50 mcg/day by mouth. As part of the teaching plan, the nurse emphasizes that this medication:
- A. Should be taken in the morning
- B. May increase the client's energy level
- C. Does not need to be stored in a dark container
- D. May increase the client's heart rate
Correct answer: A
Rationale: The correct answer is that levothyroxine (Synthroid) should be taken in the morning. Taking it in the morning can help prevent interference with the client's sleeping pattern, as one of the side effects of levothyroxine is insomnia. Choice B is incorrect because levothyroxine is actually used to treat hypothyroidism and can help increase energy levels. Choice C is incorrect as there is no specific requirement for levothyroxine to be stored in a dark container. Choice D is incorrect because levothyroxine is more likely to increase heart rate rather than decrease it.
4. A client with asthma has low-pitched wheezes present on the final half of exhalation. One hour later the client has high-pitched wheezes extending throughout exhalation. This change in assessment indicates to the nurse that the client
- A. Has increased airway obstruction
- B. Has improved airway obstruction
- C. Needs to be suctioned
- D. Exhibits hyperventilation
Correct answer: B
Rationale: The higher pitched a sound is, the more narrow the airway. Therefore, the obstruction has increased or worsened. With no evidence of secretions, there is no support to indicate the need for suctioning. Wheezes changing from low-pitched to high-pitched and extending throughout exhalation suggest a progression in airway constriction, indicating an increase in airway obstruction. Option B is incorrect because the change in wheezes from low to high pitch does not suggest an improvement in airway obstruction. Option C is incorrect as there is no indication of secretions requiring suctioning. Option D is incorrect as hyperventilation is not typically associated with the described change in wheezes.
5. Which question should the nurse ask the parents of a child suspected of having glomerulonephritis?
- A. Did your child fall off a bike onto the handlebars?
- B. Has the child had persistent nausea and vomiting?
- C. Has the child been itching or had a rash anytime in the last week?
- D. Has the child had a sore throat or a throat infection in the last few weeks?
Correct answer: D
Rationale: Glomerulonephritis refers to a group of kidney disorders characterized by inflammatory injury in the glomerulus. Group A ?-hemolytic streptococcal infection is a common cause of glomerulonephritis. Children with glomerulonephritis often develop symptoms after a throat infection caused by streptococcal bacteria. Therefore, asking about a sore throat or throat infection in the last few weeks is crucial to assess the possible link to glomerulonephritis. Choices A, B, and C are not directly associated with the pathophysiology of glomerulonephritis. Asking about falling off a bike, nausea and vomiting, or itching and rash do not provide relevant information for assessing glomerulonephritis in this context.
