NCLEX RN Exam Review Answers
1. A client with a new prescription for lithium carbonate for bipolar disorder is being educated by a nurse on early indications of toxicity. The nurse should include which of the following manifestations in the teachings?
- A. Constipation
- B. Polyuria
- C. Rash
- D. Tinnitus
Correct answer: B
Rationale: Polyuria is a crucial early indication of lithium toxicity. It results from the drug's effect on the kidneys, leading to increased urine output. This is a significant symptom to monitor as it can indicate potential toxicity. Constipation, rash, and tinnitus are not typically associated with early indications of lithium toxicity. Constipation is more commonly seen as a side effect of some medications, while rash and tinnitus are not specific indicators of lithium toxicity.
2. As a nursing supervisor in a long-term care facility, you prioritize strict infection control prevention measures due to the understanding that the normal aging process weakens the body's defenses. Which theory of aging supports the necessity of strict infection control prevention measures?
- A. The Programmed Longevity Theory
- B. The Immunological Theory of Aging
- C. The Endocrine Theory
- D. The Rate of Living Theory
Correct answer: B
Rationale: The theory of aging that aligns with the need for strict infection control prevention measures is the Immunological Theory of Aging. This theory posits that aging leads to a decline in the body's immune defenses and a reduced ability of antibodies to protect against infections. The other theories do not directly address the impact of aging on the immune system. The Programmed Longevity Theory focuses on genetic changes affecting aging, the Endocrine Theory emphasizes hormonal changes, and the Rate of Living Theory relates longevity to the rate of oxygen metabolism.
3. During an adolescent examination, the nurse asks a 13-year-old female to bend forward at the waist with arms hanging freely. Which of the following assessments is the nurse most likely conducting?
- A. Spinal flexibility
- B. Leg length disparity
- C. Hypostatic blood pressure
- D. Scoliosis
Correct answer: D
Rationale: The correct answer is scoliosis. During the assessment for scoliosis, the nurse asks the adolescent to bend forward at the waist with arms hanging freely to observe for any lateral deviation of the spine, uneven rib levels, or asymmetry. This assessment is a routine part of an adolescent examination, especially in females, as scoliosis is more common in this population. Choices A, B, and C are incorrect. Spinal flexibility is usually assessed through different maneuvers, leg length disparity is evaluated by measuring the length of the legs, and hypostatic blood pressure refers to a decrease in blood pressure due to immobility.
4. A nurse is assessing a client's pulse oximetry on the surgical unit. As part of routine interventions, the nurse turns off the exam light over the client's bed. Which of the following best describes the rationale for this intervention?
- A. External light sources may cause falsely high oximetry values
- B. A bright light in the client's face may cause a low pulse oximetry
- C. External light sources may cause falsely low oximetry values
- D. The client needs a dark and quiet room to recover and maintain proper oxygenation
Correct answer: A
Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings. Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values. Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values. Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.
5. A family member is complaining that the lights are too dim in the middle of the night when she comes in to visit her husband. What is the most objective response?
- A. Patients sleep better with the lights dimmed.
- B. The nightshift nurses prefer to work with less light.
- C. It's time for him to sleep, and you should, too.
- D. There's a reason we do that. Let me share a research study with you.
Correct answer: D
Rationale: The most objective response in this situation is to explain to the family member that there is a specific reason for dimming the lights and offer to share a research study to provide evidence-based information. By doing so, it helps the family member understand that the care provided is based on established practices and research, potentially alleviating her concerns and ensuring that her husband receives appropriate care. Choices A, B, and C do not address the family member's concern or provide a rationale backed by evidence, making them less suitable responses in this context.
