Nclex Exam Cram Practice Questions
1. The nurse is teaching a client about sleep and gives background information on normal sleep patterns. Which of the following substances promotes sleep?
- A. serotonin
- B. cortisol
- C. alcohol
- D. narcotics
Correct answer: A
Rationale: Serotonin is a substance found in the body that promotes sleep. It plays a role in the synthesis of a hypnogenic factor that directly induces sleep. Cortisol is a stress hormone that can disrupt sleep patterns. Alcohol can disrupt REM sleep and negatively impact sleep quality. Narcotics, like alcohol, can interfere with sleep architecture and lead to poor quality sleep. Therefore, the correct answer is serotonin as it is associated with promoting sleep, while the other substances listed can have negative effects on sleep patterns.
2. 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.
3. How far should the enema tube be inserted for a client to have a flatus-reducing enema?
- A. 4 inches.
- B. 6 inches.
- C. 2 inches.
- D. 8 inches.
Correct answer: A
Rationale: The correct answer is to insert the enema tube 4 inches. Enema tubing must be passed beyond the internal sphincter, which is typically around 4 inches in an adult. Inserting the tube only 2 inches is not far enough to reach this point. On the other hand, inserting the tube 6 or 8 inches is too far and might cause trauma to the bowel, which is unnecessary for a flatus-reducing enema. Therefore, the correct insertion depth of the enema tube is crucial to ensure effectiveness and safety in providing the intended treatment.
4. What does it mean to be a nursing advocate?
- A. makes decisions for others.
- B. encourages persons to make decisions for themselves and acts with or on behalf of the person to support those decisions.
- C. manages the care of others.
- D. is the legal representative for a person.
Correct answer: B
Rationale: A nursing advocate does not make decisions for others but instead empowers individuals to make decisions for themselves. By encouraging individuals to make their own decisions and supporting them in this process, nursing advocates uphold the principle of self-determination. This approach respects the autonomy and independence of individuals in managing their care. Therefore, the correct answer is to 'encourage persons to make decisions for themselves and act with or on behalf of the person to support those decisions.' Choices A, C, and D are incorrect as they do not align with the role of a nursing advocate in promoting patient autonomy and self-determination.
5. Several passengers aboard an airliner suddenly become weak and suffer breathing difficulty. The diagnosis is likely to be
- A. Outbreak of Asian flu.
- B. Chemical exposure.
- C. Bacterial pneumonia.
- D. Allergic reaction.
Correct answer: B
Rationale: In the scenario described, where multiple passengers on an airliner experience sudden weakness and breathing difficulty simultaneously, the most likely cause is chemical exposure. This is because a sudden onset of similar symptoms in a group of individuals suggests a common environmental factor affecting them. Options A, C, and D are less likely as they do not explain a sudden onset of symptoms in multiple individuals simultaneously. Asian flu (Option A) is a viral infection and would not typically result in sudden symptoms in multiple individuals at the same time. Bacterial pneumonia (Option C) is a localized infection and not a probable cause for a sudden onset of symptoms in a group. An allergic reaction (Option D) would usually occur in individuals with specific allergies rather than affecting a group of passengers at the same time.
