Exam Cram NCLEX RN Practice Questions
1. When assessing the force or strength of a pulse, what would the nurse recall about the pulse?
- A. Is a reflection of the heart's stroke volume
- B. Typically recorded on a 0- to 3-point scale
- C. Demonstrates elasticity of the blood vessel wall
- D. Reflects the blood volume in the arteries during diastole
Correct answer: A
Rationale: When assessing the force or strength of a pulse, the nurse should recall that it is a reflection of the heart's stroke volume. The heart pumps an amount of blood (the stroke volume) into the aorta, causing arterial walls to flare and generate a pressure wave felt as the pulse in the periphery. The force of the pulse is typically recorded on a 0- to 3-point scale, not a 0- to 2-point scale. The force of the pulse does not demonstrate the elasticity of blood vessel walls or reflect the blood volume in the arteries during diastole. Therefore, choices B, C, and D are incorrect.
2. Which term best describes changes such as retirement, grandparenting, and increased dependence on others?
- A. Moral
- B. Psychosocial
- C. Self-esteem
- D. Psychomotor
Correct answer: B
Rationale: The correct answer is 'Psychosocial.' Retirement, grandparenting, and increased dependence on others are examples of psychosocial changes because they involve social interactions, relationships, and psychological aspects. 'Moral' (Choice A) does not directly relate to the changes mentioned. 'Self-esteem' (Choice C) is more about self-perception and confidence, not the social changes mentioned. 'Psychomotor' (Choice D) refers to physical movements and skills, which are not the focus of the changes described in the question.
3. 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.
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. What is a common error when taking a pulse?
- A. Placing the index finger on the radial artery located on the thumb side of a patient's wrist.
- B. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure.
- C. Counting the pulse for 15 seconds and multiplying the number by four.
- D. None of the above will cause errors.
Correct answer: C
Rationale: The correct answer is counting the pulse for 15 seconds and multiplying the number by four. To accurately assess a patient's heart rate or pulse, it is crucial to count the pulse for a full minute. Counting for only 15 seconds and then multiplying by four may result in an inaccurate heart rate calculation. This approach could miss arrhythmias or intermittent pulsations that could be vital indicators of the patient's condition. Placing the index finger on the radial artery, which is located on the thumb side of the patient's wrist, is the correct technique for taking a pulse. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure is a valid observation and not an error in itself. Therefore, the most common error in this scenario is incorrectly calculating the pulse rate by multiplying a 15-second count by four.
