NCLEX RN Exam Prep

1. What does preload refer to?

Correct answer: B

Rationale: Preload refers to the volume of blood that enters the right side of the heart. This volume stretches the fibers in the heart before contraction. Preload is an essential factor in determining the force of ventricular contraction. Choices A, C, and D are incorrect. Choice A is incorrect because preload is specifically related to the volume of blood entering the right side of the heart. Choices C and D are incorrect as they refer to afterload, which is the pressure that the heart must overcome to pump blood out of the ventricles into the systemic or pulmonary circulation.

2. Which desired outcome written by the nurse is correctly written and measurable?

Correct answer: B

Rationale: An outcome statement must describe the observable client behavior that should occur in response to the nursing interventions. It consists of a subject, action verb, conditions under which the behavior is to be performed, and the level at which the client will perform the desired behavior. Option B is correctly written and measurable as it includes all the required elements: subject (client), action verb (lose), conditions (within the next 2 weeks), and the level at which the behavior should occur (4 lbs.). Option A lacks the conditions and a specific level, making it not measurable. Option C is a nursing intervention rather than a client goal. Option D does not provide a specific level at which the client should perform the desired behavior, making it not measurable as well.

3. What would be an appropriate evaluation statement for the nurse to write based on the client's ability to state only two signs of impaired circulation out of three as expected?

Correct answer: C

Rationale: The appropriate evaluation statement for the nurse to write would be 'Goal not met: Client able to name only two signs of impaired circulation.' In this scenario, the client has only identified two out of the three signs of impaired circulation specified in the desired outcome. Therefore, the goal has not been fully achieved. It is essential in nursing practice to assess and document client progress accurately. While the client has shown some understanding by correctly identifying numbness and tingling as signs of impaired circulation, the inability to state the third sign indicates an incomplete achievement of the goal. This evaluation helps guide further interventions or educational strategies to help the client meet the desired outcome in the care plan.

4. The instructor is teaching a class on basic assessment skills. Which of the following statements is true regarding the stethoscope and its use?

Correct answer: B

Rationale: The stethoscope does not magnify sound but effectively blocks out extraneous room noises. The correct orientation of the earpieces is with the slope pointing forward toward the examiner's nose, not posteriorly. The tubing length of a stethoscope should ideally be between 14 to 18 inches (36 to 46 cm) to avoid sound distortion. Using tubing longer than this range can distort sound. Both the fit and quality of the stethoscope are crucial for accurate auscultation and assessment, highlighting their significance in clinical practice. Therefore, the correct answer is that the stethoscope blocks out extraneous room noise but does not magnify sound.

5. 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.
