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. 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.

3. Which of the following items of subjective client data would be documented in the medical record by the nurse?

A. Client's face is pale
B. Cervical lymph nodes are palpable
C. Nursing assistant reports client refused lunch
D. Client feels nauseated

Correct answer: D

Rationale: The correct answer is 'Client feels nauseated.' Subjective data refers to the client's sensations, feelings, and perception of their health status. It can only be reported by the client as it is based on their personal experiences. The feeling of nausea is a subjective symptom that the client experiences and can provide insight into their health condition. Choices A and B represent objective data, as they describe observable or measurable findings that can be detected by the nurse. Choice C involves information reported by someone other than the client, making it indirect and not purely subjective.

4. What is the primary purpose of a patient care meeting or conference?

A. the patient's ability to pay for the costs of their care
B. how the healthcare team can best meet the patient's needs
C. the patient's physical status and condition
D. the patient's psychosocial status and condition

Correct answer: B

Rationale: The primary purpose of a patient care meeting or conference is to determine how the healthcare team can best meet the patient's needs. These meetings involve discussions among healthcare professionals to tailor the care plan to the specific needs and preferences of the patient. Option A is incorrect because financial discussions are generally not the primary focus of patient care meetings. Option C is incorrect as the patient's physical status is usually already known and is not the primary purpose of the meeting. Option D is incorrect as psychosocial aspects, while important, are not the sole focus of the meeting, which is primarily about addressing the patient's overall needs and preferences.

5. The client is being discharged to a long-term care (LTC) facility. The nurse is preparing a progress note to communicate to the LTC staff the client's outcome goals that were met and those that were not. To do this effectively, the nurse should:

A. Formulate post-discharge nursing diagnoses
B. Draw conclusion about resolution of current client problems
C. Assess the client for baseline data to be used at the LTC facility
D. Plan the care that is needed in the LTC facility

Correct answer: B

Rationale: To effectively communicate the client's outcome goals that were met and those that were not to the LTC staff, the nurse should draw conclusions about the resolution of the current client problems. Terminal evaluation is performed to determine the client's condition at discharge, focusing on which goals were achieved and which were not. Formulating post-discharge nursing diagnoses (option A) is not the most appropriate action in this scenario as it focuses on identifying potential problems after discharge rather than evaluating achieved goals. Assessing the client for baseline data (option C) is not necessary at this point as the focus is on evaluating outcomes rather than collecting baseline data. Planning the care needed in the LTC facility (option D) is premature as this should be done on admission to the LTC facility and not during the discharge process.
