NCLEX RN Predictor Exam
1. Which vacutainer tubes should be used when a requisition calls for blood to be drawn for an H&H and glucose test?
- A. One light blue, one red
- B. Two lavenders
- C. One lavender, one grey
- D. One green, one red
Correct answer: D
Rationale: The correct answer is 'One green, one red.' An H&H test involves hemoglobin and hematocrit, which are components of a complete blood count and are typically drawn in a lavender tube. On the other hand, blood for glucose testing is collected in grey tubes. Therefore, when drawing blood for both an H&H and glucose test, one green tube for glucose and one red tube for H&H should be used. The other choices are incorrect because light blue tubes are used for coagulation studies, lavender tubes are for complete blood counts, and green tubes are for chemistry tests like glucose, while grey tubes are specifically for glucose testing.
2. During a client interview, which of the following leading questions should the nurse avoid asking?
- A. What medication do you take at home?
- B. You are really excited about the plastic surgery, aren't you?
- C. Were you aware I've had this same type of surgery?
- D. What would you like to talk about?
Correct answer: B
Rationale: The nurse should avoid asking leading questions during a client interview as they can influence the client's response. Option B is a leading question as it suggests an expected response from the client, potentially biasing the information provided. This can lead to inaccurate data collection and subsequent errors in diagnostic reasoning. Choices A, C, and D are open-ended questions that encourage the client to provide unbiased information and allow for a more comprehensive assessment.
3. What is the flap of tissue that covers the trachea upon swallowing called?
- A. Epidermis
- B. Endocardium
- C. Epiglottis
- D. Epistaxis
Correct answer: C
Rationale: The correct answer is C: Epiglottis. The epiglottis is a flap of tissue that covers the trachea when swallowing to prevent food or liquid from entering the airway. Choice A, Epidermis, is the outer layer of the skin and is not related to the trachea. Choice B, Endocardium, is the inner lining of the heart chambers and is also unrelated to the trachea. Choice D, Epistaxis, refers to a nosebleed and is not the correct term for the tissue covering the trachea.
4. Which nursing intervention is the highest priority for a client at risk for falls in a hospital setting?
- A. Keep all of the side rails up
- B. Review prescribed medications
- C. Complete the "get up and go"? test
- D. Place the bed in the lowest position
Correct answer: D
Rationale: The highest priority nursing intervention for a client at risk for falls in a hospital setting is to place the bed in the lowest position. This action ensures that the client falls the shortest distance, reducing the risk of injury. Keeping all side rails up (Option A) may lead to a fall with injury, as the client might attempt to get over the rail and fall from a higher distance. Reviewing prescribed medications (Option B) is important as certain medications can increase the risk of falling, but it is not the best answer as it is not applicable to all clients. Completing the "get up and go"? test (Option C) can help assess a client's risk for falling but does not directly prevent injury.
5. 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.
