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. Regardless of their practice area, nurses should be concerned with:
- A. all drug-resistant bacteria.
- B. microorganisms that are critical.
- C. transmission of microorganisms.
- D. overprescription of bacteriostatic drugs.
Correct answer: C
Rationale: All nurses should be concerned with preventing the transmission of microorganisms to themselves and others. A primary way to achieve this is through asepsis. Nursing practice emphasizes providing a safe environment to shield clients, family, and healthcare providers from infections. Choices A, B, and D are incorrect. While drug-resistant bacteria, critical microorganisms, and overprescription of bacteriostatic drugs are important, nurses' primary focus should be on preventing microorganism transmission to ensure safety and well-being.
3. Which type of diet should the nurse provide to help a client who has major burns maintain a positive nitrogen balance?
- A. high protein
- B. high carbohydrate
- C. low carbohydrate
- D. low protein
Correct answer: A
Rationale: Clients with major burns are in a hypermetabolic state, leading to increased protein catabolism. Therefore, a high-protein diet is essential to help them maintain a positive nitrogen balance and support wound healing. High carbohydrate diets do not directly contribute to achieving a positive nitrogen balance, making choice B incorrect. Similarly, low carbohydrate diets are not recommended for clients with major burns as carbohydrates provide essential energy needed for healing. Low protein diets are contraindicated for clients with major burns as they require higher protein intake to support tissue repair and prevent further breakdown.
4. Pulling is easier than pushing. So pulling a client rather than pushing them has which of the following advantages?
- A. reduces workload
- B. decreases opposition from gravity
- C. maintains stability
- D. prevents muscle strain
Correct answer: A
Rationale: When pulling a client, you work with the gravitational force instead of opposing it, which reduces the workload on your muscles. Choosing to pull a client minimizes the effort required compared to pushing. Choice B is incorrect because the force of gravity remains constant regardless of pushing or pulling. Choice C is irrelevant as stability is not directly related to the advantage of pulling over pushing. Choice D is inaccurate because pulling can still strain muscles if not executed correctly, but it generally reduces the overall workload in comparison to pushing.
5. Which of the following represents a normal serum potassium level?
- A. 1.5 mEq/L
- B. 3.0 mEq/L
- C. 4.0 mEq/L
- D. 6.0 mEq/L
Correct answer: C
Rationale: The correct answer is 4.0 mEq/L. Normal serum potassium levels typically range from 3.5-5.5 mEq/L. Choice A (1.5 mEq/L) is below the normal range, Choice B (3.0 mEq/L) is also below the normal range, and Choice D (6.0 mEq/L) is above the normal range. Therefore, the only option within the normal range is Choice C (4.0 mEq/L).
