NCLEX RN Exam Preview Answers
1. The nurse is unable to palpate the right radial pulse on a patient. What would the nurse do next?
- A. Auscultate over the area with a fetoscope.
- B. Use a goniometer to measure the pulsations.
- C. Use a Doppler device to check for pulsations over the area.
- D. Check for the presence of pulsations with a stethoscope.
Correct answer: C
Rationale: When a nurse is unable to palpate a radial pulse, the next step is to use a Doppler device to check for pulsations over the area. Doppler devices are specifically designed to augment pulse or blood pressure measurements. Auscultating with a fetoscope is used to listen to fetal heart tones and is not relevant in this scenario. Goniometers are used to measure joint range of motion and are not used to assess pulses. Stethoscopes are primarily used to auscultate breath, bowel, and heart sounds, not to check for pulsations in peripheral pulses. Therefore, the correct course of action when unable to palpate a pulse is to utilize a Doppler device to assess for pulsations in the radial pulse area.
2. Who should be members of a patient care conference?
- A. Doctors, nurses, and nursing assistants since they are healthcare providers
- B. Doctors, nurses, and the patient and/or the family members
- C. ALL members of the healthcare team
- D. ALL members of the healthcare team and the patient/resident
Correct answer: D
Rationale: In a patient care conference, it is essential to have all members of the healthcare team present to ensure comprehensive and coordinated care. Including the patient or resident, along with their family members if desired, is crucial as they are the focus of care. Choice A is incorrect because it excludes other important members of the healthcare team. Choice B is partially correct as it includes the patient and/or family members but does not encompass the entire healthcare team. Choice C is too broad and does not specifically address the inclusion of the patient or resident. The correct answer, Choice D, includes all healthcare team members and the patient/resident, ensuring a holistic approach to patient-centered care.
3. While auscultating heart sounds, the nurse hears a murmur. Which of these instruments would be used to assess this murmur?
- A. Electrocardiogram
- B. Bell of the stethoscope
- C. Diaphragm of the stethoscope
- D. Palpation with the nurse's palm of the hand
Correct answer: B
Rationale: The correct instrument to assess a murmur while auscultating heart sounds is the bell of the stethoscope. An electrocardiogram is used to measure the heart's electrical activity, not to assess murmurs. Palpation with the nurse's palm of the hand is a method to assess pulses or textures, not heart murmurs. The diaphragm of the stethoscope is typically used for high-pitched sounds like breath, bowel, and normal heart sounds, whereas the bell is more suitable for soft, low-pitched sounds such as murmurs or extra heart sounds.
4. When providing endotracheal suctioning, for how long should the nurse suction the endotracheal tube of an intubated client on a ventilator at a time?
- A. Five seconds or less
- B. Ten seconds or less
- C. At least 30 seconds
- D. No longer than 60 seconds
Correct answer: B
Rationale: When providing endotracheal suctioning, the nurse should suction for no longer than ten seconds at a time. Suctioning for longer than ten seconds may cause hypoxia or bronchospasm. Extended suctioning may also place the client at risk of injury to the bronchial and tracheal structures. Choices C and D suggest prolonged suctioning durations that can lead to adverse effects on the client. Choice A, suctioning for five seconds or less, may not be adequate to clear secretions effectively, making choice B the most appropriate duration for safe and efficient suctioning in this scenario.
5. Rales and rhonchi are frequently noted during an examination of lung sounds. What is the difference between the two?
- A. Rales are louder.
- B. Rhonchi are noted only in infants.
- C. Rales occur on inspiration, rhonchi on expiration.
- D. Rales are noted only in infants.
Correct answer: C
Rationale: The correct answer is that rales occur on inspiration, while rhonchi occur on expiration. Rales are typically heard during inhalation when there is fluid in the alveoli or air passages. Rhonchi, on the other hand, are caused by air passing through obstructed airways during exhalation due to secretions in the respiratory tract. Choice A is incorrect because the loudness of the sounds is not the primary distinguishing factor between rales and rhonchi. Choice B is incorrect as rhonchi can be heard in individuals beyond infancy. Choice D is incorrect as rales can be present in patients of various age groups, not just infants.
