NCLEX RN Predictor Exam
1. When printing out an EKG, a nurse notices that the QRS complexes are extremely small. What should be the next step?
- A. Alert the physician immediately as this is a sign of impending cardiac arrest.
- B. Check to see that all leads are attached and rerun the EKG.
- C. Increase the sensitivity control to 20 mm deflection.
- D. Decrease the run speed to 50.
Correct answer: C
Rationale: Increasing the sensitivity control to 20 mm deflection will double the sensitivity, allowing for better observation of the small QRS complexes. This step is crucial in obtaining a clearer EKG reading. Choice A is incorrect because small QRS complexes do not necessarily indicate impending cardiac arrest; it's more likely a technical issue. Choice B is not the first step to take when small QRS complexes are observed; it's important to adjust the settings first. Choice D is incorrect because decreasing the run speed to 50 is not the appropriate action for this situation; adjusting the sensitivity control is more relevant to improve the visualization of the complexes.
2. A client is about to have a TENS unit attached for pain relief. Which of the following actions is most appropriate in this situation?
- A. Inform the client that he may experience tingling sensations.
- B. Connect the TENS unit before the client goes to bed for the night.
- C. Inform the client that the TENS unit may have pain-reducing effects for 10 to 15 days.
- D. After treatment, inform the client that he may not use a TENS unit again for at least 2 weeks.
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.
3. The patient with migraine headaches has a seizure. After the seizure, which action can you delegate to the nursing assistant?
- A. Document the seizure
- B. Perform neurologic checks
- C. Take the patient's vital signs
- D. Restrain the patient for protection
Correct answer: C
Rationale: After a patient with migraine headaches has a seizure, it is important to assess their vital signs to monitor their condition. This task can be safely delegated to a nursing assistant as it falls within their scope of practice. Documenting the seizure and performing neurologic checks require a higher level of training and should be done by a nurse or healthcare provider. Restraint should never be used as a first-line intervention after a seizure unless there is an immediate threat to the patient's safety, and it should be done following proper protocols and with appropriate training.
4. In a 68-year-old man, a gradual loss of hearing is known as _____________.
- A. presbycusis
- B. xerostomia
- C. myopia
- D. presbyopia
Correct answer: A
Rationale: The correct answer is 'presbycusis.' Presbycusis is the age-related gradual loss of hearing ability, commonly seen in the elderly population. Xerostomia refers to dry mouth, myopia is nearsightedness, and presbyopia is the age-related loss of the eye's ability to focus on close objects. Given Mr. Roberts' age and symptom of gradual hearing loss, presbycusis is the most likely diagnosis. Xerostomia, myopia, and presbyopia do not match the sensory change described in the question, making them incorrect choices.
5. A client is taking a walk down the hallway when she suddenly realizes that she needs to use the restroom. Although she tries to make it to the bathroom on time, she is incontinent of urine before reaching the toilet. What type of incontinence does this situation represent?
- A. Relex incontinence
- B. Urge incontinence
- C. Total incontinence
- D. Functional incontinence
Correct answer: D
Rationale: Functional incontinence occurs when a client develops an urge to void but may not be able to reach the toilet in time. In this scenario, the client had the urge to use the restroom but was unable to make it in time, leading to incontinence. Functional incontinence may be related to conditions that cause the client to forget bladder sensation until the last minute, such as cognitive changes, or the client may have mobility problems that prevent her from reaching the bathroom in time. Choice A, Reflex incontinence, is incorrect as reflex incontinence is characterized by the involuntary loss of urine due to hyperreflexia of the detrusor muscle. Choice B, Urge incontinence, is not the correct answer as urge incontinence is the involuntary loss of urine associated with a strong desire to void. Choice C, Total incontinence, is also incorrect as it refers to the continuous and unpredictable loss of urine, not specifically related to the inability to reach the toilet in time.
