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. During an examination, a nurse notices a draining ulceration on a patient's lower leg. What is the most appropriate action in this situation?
- A. Wash hands and then contact the physician.
- B. Continue to examine the ulceration and then wash hands.
- C. Wash hands, put on gloves, and continue with the examination of the ulceration.
- D. Wash hands, proceed with the rest of the physical examination, and perform the examination of the leg ulceration last.
Correct answer: C
Rationale: In this scenario, the most appropriate action is to wash hands, put on gloves, and then continue examining the ulceration. Wearing gloves is crucial when there is a possibility of contact with body fluids, as in the case of a draining ulceration. Contacting the physician is not necessary at this point; the immediate focus should be on proper infection control by washing hands and wearing gloves. Changing the order of the examination is not recommended as it is important to follow a systematic approach to avoid missing any crucial assessments.
3. When checking for proper blood pressure cuff size, which guideline is correct?
- A. The standard cuff size is appropriate for all sizes.
- B. The length of the rubber bladder should equal 80% of the arm circumference.
- C. The width of the rubber bladder should equal 80% of the arm circumference.
- D. The width of the rubber bladder should equal 40% of the arm circumference.
Correct answer: D
Rationale: When selecting the correct blood pressure cuff size, it is essential to ensure that the width of the rubber bladder equals 40% of the circumference of the person's arm. This ensures proper fitting and accurate readings. The length of the bladder should actually equal 80% of the arm circumference, not 80% of the width, making choices B and C incorrect. Choice A stating that the standard cuff size is appropriate for all sizes is inaccurate, as using an incorrectly sized cuff can lead to inaccurate blood pressure readings.
4. A patient is diagnosed with essential hypertension. Which of the following blood pressures would you expect to see in this patient prior to taking medications for the condition?
- A. 142/92
- B. 118/72
- C. 120/80
- D. 138/88
Correct answer: A
Rationale: Before starting medications for essential hypertension, a patient would typically present with a blood pressure reading equal to or greater than 140/90. This indicates high blood pressure and is characteristic of essential hypertension. Choice A, 142/92, falls within this range, making it the correct answer. Choices B (118/72), C (120/80), and D (138/88) all have blood pressure readings that are within the normal range and would not typically be expected in a patient diagnosed with essential hypertension. Therefore, choices B, C, and D are incorrect as they do not align with the elevated blood pressure levels seen in essential hypertension.
5. The healthcare professional notices that a colleague is preparing to check the blood pressure of a patient who is obese by using a standard-sized blood pressure cuff. How would this likely affect the blood pressure reading?
- A. Yield a falsely low blood pressure
- B. Yield a falsely high blood pressure
- C. Be the same, regardless of cuff size
- D. Vary as a result of the technique of the person performing the assessment
Correct answer: B
Rationale: Using a cuff that is too narrow for an obese patient would likely yield a falsely high blood pressure reading. This occurs because the standard cuff is too small for the arm's circumference, requiring more pressure to compress the artery. A tight cuff can lead to inaccurate and elevated blood pressure readings. Choices A, C, and D are incorrect because using an improperly sized cuff would not yield a falsely low blood pressure, the blood pressure reading does vary with cuff size, and the technique of the person performing the assessment is not the primary factor affecting the reading in this situation.
