NCLEX RN Exam Review Answers
1. A 45-year-old woman is prescribed ropinirole (Requip) for Parkinson's Disease. The patient is living at home with her daughter. The nurse is most concerned about which side effect of ropinirole?
- A. Slurred speech
- B. Sudden dizziness
- C. Mask-like facial expression
- D. Stooped posture
Correct answer: B
Rationale: The correct answer is 'Sudden dizziness.' Dizziness and orthostatic hypotension are serious adverse effects of ropinirole that can lead to an increased risk of falls. Ropinirole belongs to the drug class of dopamine agonists, which mimic dopamine in the brain (Parkinson's Disease is characterized by a lack of dopamine). 'Slurred speech' is not a common side effect of ropinirole. 'Mask-like facial expression' and 'Stooped posture' are more associated with the progression of Parkinson's Disease itself rather than a side effect of ropinirole.
2. A client in the ICU has been intubated and placed on a ventilator. The physician orders synchronous intermittent mandatory ventilation (SIMV). Which statement best describes the work of this mode of ventilation?
- A. The ventilator delivers a set rate and tidal volume regardless of whether the client is attempting to breathe
- B. The ventilator coordinates delivered breaths with the client's respiratory efforts
- C. The ventilator provides a supplemental breath for every third breath of the client
- D. The ventilator provides breaths during the expiratory phase of the client's respirations
Correct answer: B
Rationale: Synchronous intermittent mandatory ventilation (SIMV) is a ventilation mode that coordinates delivered breaths with the client's own respiratory efforts. This mode allows the client to initiate breaths, with the ventilator providing preset breaths at a controlled rate and volume. Option A is incorrect because in SIMV, the ventilator syncs with the client's respiratory efforts. Option C is incorrect as it does not accurately depict the way SIMV works. Option D is also incorrect as SIMV does not specifically provide breaths during the expiratory phase of the client's respirations. Therefore, the correct answer is B, where the ventilator coordinates breath delivery with the client's breathing efforts.
3. What drives respiration in a patient with advanced chronic respiratory failure?
- A. Hypoxemia
- B. Hypocapnia
- C. Hypercapnia
- D. None of the above
Correct answer: A
Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.
4. A physician suspects a patient may have pancreatitis. Which of the following tests would be most appropriate to diagnose this condition?
- A. CK and Troponin
- B. BUN and Creatinine
- C. Amylase and Lipase
- D. HDL and LDL Cholesterol Levels
Correct answer: C
Rationale: To diagnose pancreatitis, testing amylase and lipase levels is crucial. Amylase and lipase are enzymes produced by the pancreas that help digest carbohydrates and lipids. In pancreatitis, these enzymes are released in high amounts into the bloodstream due to pancreatic inflammation or damage. Elevated levels of amylase and lipase in blood tests strongly indicate pancreatitis. Choice A, CK and Troponin, are cardiac markers used in diagnosing heart conditions like myocardial infarction, not pancreatitis. Choice B, BUN and Creatinine, are kidney function tests, not specific to pancreatitis. Choice D, HDL and LDL Cholesterol Levels, are lipid profile tests used to assess cardiovascular health, not for diagnosing pancreatitis.
5. A 34-year-old patient with chronic hepatitis C infection has several medications prescribed. Which medication requires further discussion with the healthcare provider before administration?
- A. Ribavirin (Rebetol, Copegus) 600 mg PO bid
- B. Pegylated ?-interferon (PEG-Intron, Pegasys) SQ weekly
- C. Diphenhydramine (Benadryl) 25 mg PO every 4 hours PRN itching
- D. Dimenhydrinate (Dramamine) 50 mg PO every 6 hours PRN nausea
Correct answer: B
Rationale: The correct answer is B: Pegylated ?-interferon (PEG-Intron, Pegasys) SQ weekly. Pegylated ?-interferon is typically administered once weekly, not daily. Therefore, this medication requires further discussion with the healthcare provider before administration to ensure the correct dosing frequency. Ribavirin, choice A, is appropriate for chronic hepatitis C treatment. Choices C and D, Diphenhydramine and Dimenhydrinate, are commonly used for symptomatic relief in patients with hepatitis C and do not require further discussion with the healthcare provider in this context.
