NCLEX RN Predictor Exam
1. Each small square on the EKG paper is:
- A. 0.04 seconds long and 5mm tall
- B. 0.2 seconds long and 5mm tall
- C. 0.04 seconds long and 20mm tall
- D. 0.04 seconds long and 1mm tall
Correct answer: D
Rationale: Each small square on an EKG paper represents 0.04 seconds long and 1mm tall. This standardization is essential for accurate measurements. One large square on EKG paper consists of 5 small squares in length and 5 small squares in height, which equals 0.2 seconds long and 5mm tall (0.5 mV). Choice A is incorrect because while the duration is correct, the height mentioned is not accurate. Choice B is incorrect as it provides the correct height but the duration is inaccurate. Choice C is incorrect as the height mentioned is exaggerated, and the duration is correct but the height is not. Therefore, the correct answer is 0.04 seconds long and 1mm tall.
2. What does the medical term 'basophilia' refer to?
- A. An attachment of the epithelial cells of the skin to a basement membrane
- B. An overabundance of a particular white blood cell in the peripheral blood
- C. An underrepresentation of basophils on a blood smear
- D. None of the above
Correct answer: B
Rationale: The correct answer is 'An overabundance of a particular white blood cell in the peripheral blood.' Basophilia specifically indicates an increased number of basophils in the peripheral blood. It can be observed in conditions like leukemia and certain allergic reactions. Choice A is incorrect as it describes something unrelated to basophilia. Choice C is incorrect as it suggests a decrease in basophils, which is opposite to the actual meaning of basophilia. Choice D is also incorrect as basophilia does have a defined medical significance.
3. During an assessment, a nurse asks a patient, "If you had fever and vomiting for 3 days, what would you do?"? Which aspect of the mental status examination is the nurse assessing?
- A. Behavior
- B. Cognition
- C. Affect and mood
- D. Perceptual disturbances
Correct answer: B
Rationale: The nurse is assessing cognition in this scenario. Cognition involves evaluating a patient's judgment and decision-making abilities. By asking the patient what they would do in a specific situation, the nurse aims to determine the patient's cognitive function. A correct response indicating intact cognition would involve a decision like 'Call my doctor.' If the patient suggests inappropriate actions like 'I would stop eating' or 'I would just wait and see what happened,' it would suggest impaired judgment. The other options, behavior, affect and mood, and perceptual disturbances, refer to different aspects of the mental status examination and are not directly assessed through this question.
4. Which of the following descriptors is most appropriate to use when stating the 'problem' part of a nursing diagnosis?
- A. Grimacing
- B. Anxiety
- C. Oxygenation saturation 93%
- D. Output 500 mL in 8 hours
Correct answer: B
Rationale: The problem part of a nursing diagnosis in the context of nursing care plans should focus on the client's response to a life process, event, or stressor. This response is what is used to identify the nursing diagnosis. 'Anxiety' is the most appropriate descriptor for the problem part of a nursing diagnosis as it reflects a psychological response that can be addressed by nursing interventions. 'Grimacing' is a physical manifestation and not the problem itself. 'Oxygenation saturation 93%' and 'Output 500 mL in 8 hours' are data points or cues that a nurse would use to formulate the nursing diagnostic statement, not the actual problem being addressed.
5. The nurse is assessing the vital signs of a 20-year-old marathon runner and documents the following vital signs: temperature"?36�C; pulse"?48 beats per minute; respirations"?14 breaths per minute; blood pressure"?104/68 mm Hg. Which statement is true concerning these results?
- A. The patient is experiencing bradycardia.
- B. These are normal vital signs for a healthy, athletic adult.
- C. The patient's pulse rate is not normal"?no action is required.
- D. The patient's next clinic visit should occur as scheduled.
Correct answer: B
Rationale: The correct answer is, 'These are normal vital signs for a healthy, athletic adult.' A pulse rate of 48 beats per minute is considered bradycardia in adults, but it is not a concern in well-trained athletes like marathon runners. Bradycardia is a normal physiological response to aerobic conditioning. Tachycardia, on the other hand, is defined as a pulse rate above 100 beats per minute, which is not the case here. The low pulse rate in this scenario is a reflection of the athlete's cardiovascular fitness. Therefore, there is no need to notify the physician or schedule a follow-up visit based on these findings.
