Nclex Exam Cram Practice Questions
1. What is the most likely reason for a hospitalized adult client who routinely works from midnight until 8 a.m. to have a temperature of 99.1�F at 4 a.m.?
- A. delta sleep
- B. slow brain waves
- C. pneumonia
- D. circadian rhythm
Correct answer: D
Rationale: The correct answer is 'circadian rhythm.' Circadian rhythms are biological cycles that last about 24 hours. The sleep-wake cycle is closely tied to circadian rhythms, affecting body temperature. Normally, core body temperature drops during sleep, reaching its 24-hour low around 4 a.m. In this case, the client's temperature of 99.1�F at 4 a.m. is likely due to the disruption of their circadian rhythm caused by working from midnight until 8 a.m. Choices A, B, and C are incorrect because delta sleep, slow brain waves, and pneumonia do not directly explain the temperature fluctuation based on circadian rhythm.
2. What is a predisposing factor for cancer of the tongue?
- A. tobacco use
- B. obesity
- C. sun exposure
- D. eating sweets
Correct answer: A
Rationale: Tobacco use is a well-established predisposing factor for cancer of the tongue. Smoking or chewing tobacco can lead to the development of oral cancers, including those affecting the tongue. Obesity, sun exposure, and eating sweets are not directly linked to an increased risk of tongue cancer. Obesity may be associated with other types of cancer, sun exposure can lead to skin cancer, and eating sweets is not a known risk factor for tongue cancer. Therefore, the correct answer is tobacco use, as it has a strong association with the development of tongue cancer, making it a significant predisposing factor.
3. Which of the following lab values is associated with a decreased risk of cardiovascular disease?
- A. high HDL cholesterol
- B. low HDL cholesterol
- C. low total cholesterol
- D. low triglycerides
Correct answer: B
Rationale: High HDL cholesterol is associated with a decreased risk of cardiovascular disease because HDL cholesterol is known as 'good' cholesterol. It helps remove other forms of cholesterol, like LDL cholesterol, from the bloodstream, reducing the risk of plaque buildup in the arteries. Low HDL cholesterol (Choice B) is actually a risk factor for cardiovascular disease because it means there is less of the 'good' cholesterol to perform its protective functions. Low total cholesterol (Choice C) and low triglycerides (Choice D) are not necessarily associated with a decreased risk of cardiovascular disease, as the balance and types of cholesterol play a more crucial role in heart health.
4. Nurses caring for clients who have cancer and are taking opioids need to assess for all of the following except:
- A. tolerance.
- B. constipation.
- C. sedation.
- D. addiction.
Correct answer: D
Rationale: When caring for clients with cancer who are taking opioids, nurses need to assess for tolerance, constipation, and sedation as these are common side effects of opioid use. Addiction, however, is not a primary concern when treating pain in terminally ill clients. Terminally ill patients are usually not at risk of developing addiction to opioids due to their short life expectancy and the focus on pain management rather than the potential for addiction. Therefore, the correct answer is 'addiction.' Choices A, B, and C are essential considerations when managing clients on opioids for pain control.
5. How many feet should separate the nurse and the source when extinguishing a small, wastebasket fire with an appropriate extinguisher?
- A. 1 foot
- B. 2 feet
- C. 4 feet
- D. 6 feet
Correct answer: D
Rationale: The nurse should stand about 6 feet from the source of the fire. Getting closer might put the nurse in danger. Choice A, 1 foot, is incorrect because it is too close to the fire and can expose the nurse to unnecessary risk. Choice B, 2 feet, is also too close to the fire and may lead to potential harm. Similarly, choice C, 4 feet, is not the ideal distance as it is still within the range of potential danger. The correct answer is D, 6 feet, which is a safe distance for the nurse to extinguish the fire effectively without risking personal safety.
