NCLEX RN Exam Preview Answers
1. The nurse is caring for a patient who has a right-sided chest tube after a right lower lobectomy. Which nursing action can the nurse delegate to the unlicensed assistive personnel (UAP)?
- A. Document the amount of drainage every eight hours
- B. Obtain samples of drainage for culture from the system
- C. Assess patient pain level associated with the chest tube
- D. Check the water-seal chamber for the correct fluid level
Correct answer: A
Rationale: The correct answer is to document the amount of drainage every eight hours. UAP education typically includes tasks related to documentation of intake and output. Obtaining samples of drainage for culture and assessing patient pain level are nursing responsibilities that require licensed nursing personnel's education and scope of practice. Checking the water-seal chamber for the correct fluid level also falls under the nursing role, as it involves monitoring and maintaining the chest tube system, which requires nursing knowledge and training.
2. An examiner is using an ophthalmoscope to examine a patient's eyes. The patient has astigmatism and is nearsighted. Which of these techniques by the examiner would indicate that the examination is being correctly performed?
- A. Rotating the lens selector dial to bring the object into focus
- B. Using the large full circle of light when assessing pupils that are not dilated
- C. Rotating the lens selector dial to the black numbers to compensate for astigmatism
- D. Using the grid on the lens aperture dial to visualize the external structures of the eye
Correct answer: A
Rationale: To correctly perform an eye examination using an ophthalmoscope on a patient with astigmatism and nearsightedness, the examiner should rotate the lens selector dial to bring the object into focus. This adjustment helps compensate for nearsightedness or farsightedness but does not correct astigmatism. Rotating the lens selector dial to the black numbers is not an appropriate technique for compensating for astigmatism. Using the grid on the lens aperture dial is primarily for visualizing external structures of the eye, not for addressing refractive errors. The large full circle of light is typically used when assessing dilated pupils, not for examining patients with astigmatism and nearsightedness. Therefore, the correct technique is rotating the lens selector dial to bring the object into focus.
3. A client is diagnosed with ariboflavinosis. Which of the following foods should the nurse serve this client?
- A. Citrus fruits
- B. Milk
- C. Fish
- D. Potatoes
Correct answer: B
Rationale: Ariboflavinosis is a vitamin B-2 deficiency. Symptoms may include cracks around the mouth, inflammation of the tongue, or light sensitivity. Foods rich in vitamin B-2, like milk, liver, green vegetables, or whole grains, are recommended. Citrus fruits (choice A) are good sources of vitamin C, not B-2. Fish (choice C) is a source of protein and omega-3 fatty acids but not a significant source of vitamin B-2. Potatoes (choice D) are a source of carbohydrates but do not provide high levels of vitamin B-2.
4. An experienced healthcare professional instructs a new colleague on caring for a patient with dyspnea due to a pulmonary fungal infection. Which action by the new colleague indicates a need for further teaching?
- A. Listening to the patient's lung sounds several times during the shift
- B. Placing the patient in droplet precautions and in a private hospital room
- C. Increasing the oxygen flow rate to maintain oxygen saturation above 90%
- D. Monitoring the patient's serology results to identify the specific infecting organism
Correct answer: B
Rationale: The correct answer is placing the patient in droplet precautions and in a private hospital room. Fungal infections are not transmitted from person to person, so isolation procedures like droplet precautions are unnecessary. Listening to the patient's lung sounds, increasing the oxygen flow rate, and monitoring serology results are all appropriate actions in caring for a patient with dyspnea caused by a pulmonary fungal infection.
5. The healthcare professional is preparing to use a stethoscope for auscultation. Which statement is true regarding the diaphragm of the stethoscope?
- A. Used to listen for high-pitched sounds
- B. Used to listen for low-pitched sounds
- C. Should be firmly held against the person's skin to block out low-pitched sounds
- D. Should be lightly held against the person's skin to listen for extra heart sounds and murmurs
Correct answer: A
Rationale: The diaphragm of the stethoscope is designed for listening to high-pitched sounds like breath, bowel, and normal heart sounds. It should be firmly held against the person's skin to ensure optimal sound transmission, leaving a ring after use. On the other hand, the bell of the stethoscope is ideal for detecting soft, low-pitched sounds such as extra heart sounds or murmurs. Therefore, the diaphragm is not used to block out low-pitched sounds but rather to enhance the detection of high-frequency sounds.
