NCLEX RN Practice Questions Exam Cram

1. Application - The nurse is caring for a patient who has the following labs: Creatinine 2.5mg/dL, WBC 11,000 cells/mL, and Hemoglobin of 12 g/dL. Based on this information, which of these orders would the nurse question?

A. Administer 30 Units of Lantus Daily
B. CT of the spine with contrast
C. X-ray of the abdomen and chest
D. Administer heparin subcutaneously 5,000 Units every 12 hours

Correct answer: B

Rationale: The correct answer is to question the order for a CT of the spine with contrast. The patient's elevated creatinine level of 2.5mg/dL indicates impaired kidney function. Contrast agents are nephrotoxic and can further compromise kidney function in patients with existing nephropathy. Therefore, it is crucial to avoid contrast-enhanced imaging studies in patients with impaired renal function. Choice A: Administering 30 Units of Lantus Daily is not contraindicated based on the provided lab values. Choice C: Ordering an X-ray of the abdomen and chest is not contraindicated based on the provided lab values. Choice D: Administering heparin subcutaneously at 5,000 Units every 12 hours is not contraindicated based on the provided lab values.

2. A patient asks the nurse whether he is a good candidate to use a CPAP machine. The nurse reviews the client's history. Which condition would contraindicate the use of a CPAP machine?

A. The patient is in the late stage of dementia.
B. The patient has a history of bronchitis.
C. The patient has had suicidal gestures/attempts in the past.
D. The patient is on beta-blockers.

Correct answer: A

Rationale: The correct answer is that the patient is in the late stage of dementia. In late-stage dementia, individuals may have an inability to follow commands and understand instructions independently, which are essential for proper installation and use of a CPAP machine. This makes using a CPAP machine challenging and potentially ineffective for patients in this condition. Choice B, having a history of bronchitis, does not contraindicate the use of a CPAP machine. In fact, CPAP therapy can be beneficial for patients with respiratory conditions like bronchitis. Choice C, a history of suicidal gestures/attempts, while concerning for the patient's mental health, does not directly contraindicate the use of a CPAP machine. Choice D, being on beta-blockers, is not a contraindication for CPAP machine use. Beta-blockers are commonly used medications for various conditions and do not interfere with the use of a CPAP machine.

3. When is cleft palate repair usually performed in children?

A. A cleft palate cannot be repaired in children.
B. Repair is usually performed by age 8 weeks.
C. Repair is usually performed by 2 months of age.
D. Repair is usually performed between 6 months and 2 years.

Correct answer: D

Rationale: Cleft palate repair timing is individualized based on the severity of the deformity and the child's size. Typically, cleft palate repair is performed between 6 months and 2 years of age. This age range allows for optimal outcomes and is often done before 12 months to promote normal speech development. Early closure of the cleft palate helps to facilitate speech development. Options A, B, and C are incorrect because a cleft palate can be repaired in children, and repair is usually performed between 6 months and 2 years of age, not at 8 weeks or 2 months.

4. A client complained of nausea, a metallic taste in her mouth, and fine hand tremors 2 hours after her first dose of lithium carbonate (Lithane). What is the nurse's best explanation of these findings?

A. These side effects are common and should subside in a few days.
B. The client is probably having an allergic reaction and should discontinue the drug.
C. Taking the lithium on an empty stomach should decrease these symptoms.
D. Decreasing dietary intake of sodium and fluids should minimize the side effects.

Correct answer: A

Rationale: The correct answer is, 'These side effects are common and should subside in a few days.' Nausea, metallic taste, and fine hand tremors are common side effects of lithium carbonate (Lithane) and typically diminish within a few days as the body adjusts to the medication. Option B is incorrect because these symptoms are not indicative of an allergic reaction. Option C is incorrect as taking lithium on an empty stomach does not directly address or decrease these specific side effects. Option D is also incorrect as reducing sodium and fluid intake is not the recommended approach to managing these particular side effects of lithium.

5. Which of the following is TRUE about shock?

A. A patient with severe shock does not always have an abnormally low blood pressure.
B. Confusion and deteriorating mentation are indicative of hypotensive shock.
C. Patients with compensated shock may not be able to maintain a normal blood pressure.
D. A normal blood pressure does not imply that the patient is stable.

Correct answer: B

Rationale: Confusion and deteriorating mentation are indeed indicative of hypotensive shock. It is important to note that a patient with hypotensive shock will likely exhibit deteriorating mental status. Choice A is incorrect because a patient in severe shock may not always have an abnormally low blood pressure, making it an unreliable indicator of shock severity. Choice C is incorrect because patients with compensated shock may present with normal blood pressure but still have inadequate tissue perfusion. Choice D is incorrect because a normal blood pressure does not guarantee the patient's stability, especially in cases of shock where tissue perfusion may be compromised despite normal blood pressure readings.
