Nclex Exam Cram Practice Questions
1. After undergoing gastric resection, the client is informed by the nurse that which of the following meals is most likely to cause rapid emptying of the stomach?
- A. a high-protein meal
- B. a high-fat meal
- C. a large meal regardless of nutrient content
- D. a high-carbohydrate meal
Correct answer: D
Rationale: After gastric resection, meals high in carbohydrates are more likely to cause rapid emptying of the stomach. Carbohydrates stimulate the release of gastrin, which accelerates gastric emptying. On the other hand, high-fat and high-protein meals tend to delay gastric emptying. A large meal, regardless of nutrient content, can also delay gastric emptying due to the increased volume of food that needs to be processed.
2. A client with major head trauma is receiving bolus enteral feeding. The most important nursing order for this client is:
- A. measure intake and output.
- B. check albumin levels.
- C. monitor glucose levels.
- D. increase enteral feeding.
Correct answer: A
Rationale: The correct action for a client with major head trauma receiving bolus enteral feeding is to measure intake and output (I&O). Enteral feedings are hyperosmotic agents that can cause fluid shifts. Monitoring I&O is crucial to assess fluid balance, ensuring that input matches output. Checking albumin levels (choice B) is important for assessing nutritional status but is not the immediate priority in this situation. Monitoring glucose levels (choice C) is also important but not as critical as measuring I&O in this context. Increasing enteral feeding (choice D) should only be done based on a healthcare provider's order after assessing the patient's condition, not as the most important nursing order at this time.
3. The client is being taught about the use of Rifampin for prophylaxis following exposure to meningitis. What change in bodily functions should the client be informed about?
- A. The client's urine may turn blue.
- B. The client remains infectious to others for 48 hours.
- C. The client's contact lenses may be stained orange.
- D. The client's skin may take on a crimson glow.
Correct answer: C
Rationale: Rifampin has the unusual effect of turning body fluids an orange color. Soft contact lenses might become permanently stained. Clients should be taught about these side effects to avoid unnecessary concern. Option A is incorrect as Rifampin does not cause the urine to turn blue. Option B is incorrect as the client is not infectious to others due to taking Rifampin for prophylaxis. Option D is incorrect as Rifampin does not cause the skin to take on a crimson glow.
4. What is the 24-hour day-night cycle known as?
- A. circadian rhythm
- B. infradian rhythm
- C. ultradian rhythm
- D. non-REM rhythm
Correct answer: A
Rationale: The correct answer is circadian rhythm. Circadian rhythm refers to the rhythmic repetition of patterns that occur approximately every 24 hours, regulating various biological processes related to the day-night cycle. Infradian rhythm, which is longer than 24 hours, and ultradian rhythm, which is shorter than 24 hours, are not the correct terms for the 24-hour cycle. Non-REM rhythm does not specifically relate to the 24-hour day-night cycle, making it an incorrect choice.
5. Which of the following syndromes associated with incomplete lesions of the spinal cord results from damage to one-half of the spinal cord?
- A. Brown-S�quard syndrome
- B. posterior cord syndrome
- C. central cord syndrome
- D. cauda equina syndrome
Correct answer: A
Rationale: Brown-S�quard syndrome is indeed associated with incomplete lesions of the spinal cord, and it specifically results from damage to one-half of the spinal cord. This syndrome manifests as ipsilateral motor paralysis, ipsilateral loss of vibration and proprioception, and contralateral loss of pain and temperature sensation. Posterior cord syndrome mainly involves the loss of proprioception and vibratory sense, while sparing motor function and pain sensation. Central cord syndrome typically presents with more weakness in the upper extremities compared to the lower extremities due to central spinal cord damage. Cauda equina syndrome affects the nerve roots at the level of the conus medullaris, leading to symptoms like lower extremity weakness, numbness, and bowel/bladder dysfunction.
