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. In an emergency situation where a client is unconscious and requires immediate surgery, what action is necessary with regard to informed consent?

Correct answer: A

Rationale: In emergency situations where obtaining consent is not possible due to the client's condition, healthcare providers are allowed to perform life-saving procedures without informed consent. It is assumed that the client would want to receive necessary treatment to save their life. Therefore, the correct action is for the healthcare team to proceed with the surgery as consent is not needed. Waiting to contact the client's family for consent can delay life-saving treatment, risking the client's life. Contacting the hospital clergy for consent is unnecessary and can cause further delays. Obtaining consent from the client's legal guardian is not feasible in this critical situation and may lead to a delay in providing essential care.

3. What can happen if a restraint is attached to a side rail or other movable part of the bed?

Correct answer: B

Rationale: Attaching a restraint to a movable part of the bed can lead to client injury if that part of the bed is moved before releasing restraints. This could result in the client getting caught or trapped, possibly causing harm. Choices C and D are incorrect because attaching restraints to movable parts of the bed is not intended to help the client stay in bed or improve posture; rather, it poses a risk of injury. Choice A is incorrect as it does not address the potential harm associated with using restraints on movable parts of the bed.

4. What should be the primary action for a client who has just vomited 300 cc of bright red blood?

Correct answer: D

Rationale: The correct first action for a client who has just vomited 300 cc of bright red blood is to check the blood pressure. This assessment is crucial to evaluate for hypotension, which could indicate significant blood loss and the need for immediate intervention. Documenting the vomiting is important for the client's medical record but not the initial priority. Increasing IV fluids and getting a complete blood count are necessary steps but should follow the assessment of the client's hemodynamic status.

5. A licensed practical nurse arrives at work at the long-term care center and is immediately faced with several activities that require attention. Which activity will the nurse attend to first?

Correct answer: A

Rationale: The nurse's priority should be attending to task assignments for the day. This ensures that client care can begin promptly and efficiently. Stocking the medication closet is important but can be done after ensuring task assignments are clear. Phone messages from employee health services and a client's wife, although important, can be addressed after organizing the staff for client care.
