NCLEX RN Exam Prep Questions
Question 1 of 5
Which of the following is a fat-soluble vitamin?
Correct Answer: B
Rationale: The correct answer is Vitamin D. Fat-soluble vitamins are those that can be stored in the body, allowing excess amounts to be stored for later use. While this storage ability can help prevent deficiencies, it also poses a risk of toxicity. The fat-soluble vitamins are A, E, D, and K. Choice A, Vitamin C, is water-soluble, not fat-soluble. Choice C, Vitamin B-6, and Choice D, Riboflavin, are also water-soluble vitamins and not fat-soluble.
Question 2 of 5
Which of the following interventions is most appropriate for a client with a diagnosis of Risk for Activity Intolerance?
Correct Answer: C
Rationale: The most appropriate intervention for a client diagnosed with Risk for Activity Intolerance is to minimize environmental noise. Environmental noise can increase the energy demand on the client as they try to manage their responses to stimuli. By reducing excess noise, the nurse helps promote rest and conserves the client's energy, which is crucial in managing activity intolerance. Choice A is incorrect because increasing nursing activities may exacerbate the client's intolerance to activity. Choice B is incorrect as assessing for signs of increased muscle tone does not directly address the issue of activity intolerance. Choice D is incorrect as teaching the Valsalva maneuver is not relevant to managing activity intolerance in this scenario.
Question 3 of 5
A client is being seen for disrupted sleep patterns. The nurse encourages the client to verbalize feelings about sleep and inability to maintain adequate sleep habits. What is the rationale for this action?
Correct Answer: B
Rationale: Clients experiencing disrupted sleep patterns may have underlying anxiety or fear contributing to their poor sleep habits. Encouraging clients to verbalize their feelings about sleep allows them to address any negative emotions that may be impacting their ability to sleep well. By working through these issues, clients may experience increased peace and relaxation, which can help promote better sleep. Option A is incorrect because assuming a mental illness without evidence can lead to mismanagement of the client's care. Option C is incorrect as it does not address the underlying emotional factors affecting the client's sleep patterns. Option D is incorrect as there is a specific rationale for encouraging the client to verbalize their feelings about sleep.
Question 4 of 5
A client is about to have a TENS unit attached for pain relief. Which of the following actions is most appropriate in this situation?
Correct Answer: A
Rationale: When attaching a TENS unit for pain relief, it is essential to inform the client that he may experience tingling sensations. This is a common sensation experienced when using a TENS unit, but it should not cause muscle twitching. The therapeutic effects of a TENS unit usually last between 3 to 5 days. Choice B is incorrect because there is no specific recommendation to connect the TENS unit before bedtime. Choice C is incorrect as stating that the TENS unit may have pain-reducing effects for 10 to 15 days is inaccurate, as the effects typically last 3 to 5 days. Choice D is incorrect because there is no guideline suggesting that the client cannot use a TENS unit again for at least 2 weeks after treatment.
Question 5 of 5
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.
