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?

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. When a client needs oxygen therapy, what is the highest flow rate that oxygen can be delivered via nasal cannula?

Correct answer: C

Rationale: The correct answer is 6 liters/minute. When a client requires oxygen therapy, the maximum flow rate that oxygen can be delivered via nasal cannula is 6 liters/minute. Nasal cannula can effectively deliver oxygen up to 6 liters/minute. Flow rates exceeding 6 liters/minute may lead to drying of the nasal passages and discomfort for the client. Higher flow rates, like 8 liters/minute, should be administered using a mask to ensure sufficient oxygenation. Options A, B, and D are incorrect as they indicate flow rates that surpass the recommended maximum for nasal cannula delivery.

3. If a visitor accidentally knocks over a plastic pleural drainage system connected to a client, causing it to crack, what should the nurse do first?

Correct answer: C

Rationale: When a pleural drainage system is cracked, the nurse's initial action should be to change the drainage system. This is essential to prevent potential complications like air leaks or infections. While observing the client's response and checking for leaks are important steps, they are secondary to addressing the immediate issue of the cracked system. Notifying the physician, though necessary, can be carried out once the primary concern of the damaged system is resolved.

4. Quality is defined as a combination of all of the following except:

Correct answer: B

Rationale: Quality in any context is about meeting or exceeding customer requirements and exceeding customer expectations. It also involves conforming to standards to ensure consistency and reliability. Merely performing at the minimally acceptable level does not encompass the essence of quality, as it sets the bar at the lowest level of acceptability rather than aiming for excellence or customer satisfaction. Therefore, the correct answer is 'performing at the minimally acceptable level,' as this choice falls short in capturing the comprehensive definition of quality.

5. What is involved in client education by the nurse?

Correct answer: B

Rationale: Client education by the nurse involves providing accurate and understandable information to the client. It is essential to offer relevant details without overwhelming them, making choice B the correct answer. Choice A is incorrect because providing excessive details can confuse the client rather than empower them with necessary knowledge. Choice C is incorrect as it is not the role of the nurse to question the reality of a client's pain; instead, they should address and manage the pain effectively. Choice D is incorrect as client education focuses on providing information and empowering clients with knowledge, not just administering medication.
