NCLEX RN Predictor Exam

1. Each small square on the EKG paper is:

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. The NFPA diamond has four colors. The blue diamond:

Correct answer: A

Rationale: The National Fire Protection Agency (NFPA) uses a safety diamond to communicate the level of threat posed by a specific chemical. The blue diamond in the NFPA diamond system signifies potential health hazards associated with the use of that chemical. Choice B is incorrect because the blue diamond does not indicate anything about using water to extinguish fires. Choice C is incorrect as the NFPA diamond does not provide information on treating injuries. Choice D is also incorrect as the blue diamond does not suggest incineration upon disposal; it pertains to health hazards.

3. To accurately assess a patient's respiration rate, which of the following methods would be BEST?

Correct answer: B

Rationale: The most accurate method to assess a patient's respiration rate is to count the breaths simultaneously while counting the pulse rate. This approach ensures that the patient is unaware of the specific focus on their breathing, preventing any conscious alteration in breathing patterns. Choice A is incorrect because informing the patient may lead to altered breathing as the patient may consciously change their breathing pattern. Choice C involves counting the pulse rate first, which is not necessary for assessing respiration rate. Choice D is incorrect as it includes unnecessary steps such as taking the patient's temperature before counting respiration rate, which adds no value to accurately assessing the respiration rate.

4. During which part of the client interview would it be best for the nurse to ask, 'What's the weather forecast for today?'

Correct answer: A

Rationale: Asking about the weather initiates the social or introductory phase of the interview, allowing the nurse to establish rapport with the client at the beginning. This question can help assess the client's mental status and set a friendly tone. In the body phase, the client responds to the nurse's inquiries, while during the closing phase, either the nurse or the client concludes the interview. Therefore, the best time to ask about the weather forecast is during the introduction phase to facilitate a positive start to the interaction.

5. A parent calls the pediatric clinic and is frantic about the bottle of cleaning fluid her child drank for 20 minutes. Which of the following is the most important instruction the nurse can give the parent?

Correct answer: C

Rationale: In situations where a child has ingested a potentially harmful substance, contacting the Poison Control Center quickly is crucial. The Poison Control Center can provide specific guidance tailored to the child's situation, which can include whether immediate medical attention is necessary or if any actions need to be taken at home. Option A, 'This too shall pass,' is not appropriate as it dismisses the seriousness of the situation. Option B, 'Take the child immediately to the ER,' may not always be the best course of action without guidance from experts. Option D, 'Give the child syrup of ipecac,' is outdated advice and not recommended as a first response to poisoning incidents.
