Nursing Elites

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. When evaluating the lab work of a client in hepatic coma, which of the following lab tests is most important?

• A. blood urea nitrogen
• B. serum calcium
• C. serum ammonia
• D. serum creatinine

Correct answer: C

Rationale: When a client is in hepatic coma due to liver failure, the liver cannot metabolize amino acids completely, leading to elevated ammonia levels. Increased ammonia can cause brain-tissue irritation, worsening the coma. Therefore, monitoring serum ammonia levels is crucial in assessing the severity of hepatic coma. Choices A, B, and D are less relevant in the context of hepatic coma. Blood urea nitrogen primarily assesses kidney function, serum calcium levels are not directly related to hepatic coma, and serum creatinine is more indicative of kidney function rather than liver function in this scenario.

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

• A. The healthcare team will proceed with the surgery as consent is not needed in emergencies.
• B. The healthcare team will wait until the client's family can be contacted for consent.
• C. The healthcare team will contact the hospital clergy to provide informed consent.
• D. The healthcare team will obtain consent from the client's legal guardian before proceeding.

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.

4. How is the information documented on incident reports used?

• A. to analyze risk categories
• B. to ensure compliance with regulations
• C. to identify staff's educational needs
• D. all of the above

Correct answer: D

Rationale: The information documented on incident reports is used for various purposes, including analyzing risk categories, ensuring compliance with regulations, and identifying staff's educational needs. Incident reports provide valuable data that can be utilized in risk management, quality monitoring, and improvement programs. Therefore, the correct answer is 'all of the above.' Choices A, B, and C are all correct as incident reports are used for analyzing risk categories, ensuring compliance with regulations, and identifying staff's educational needs, respectively. Thus, the most comprehensive answer is 'all of the above.'

5. What information does the healthcare provider remember regarding do-not-resuscitate (DNR) orders in this scenario?

• A. That a DNR order may be written by a healthcare provider
• B. That everything possible must be done if the client stops breathing
• C. That medications only may be given to the client if the client stops breathing
• D. That life support measures will have to be implemented if the client stops breathing

Correct answer: A

Rationale: In a situation where a client has no family members and the client's wife is mentally incompetent, the healthcare provider may write a DNR order if it is deemed medically certain that resuscitation would be futile. A DNR order is a medical directive that instructs healthcare providers not to perform CPR if a patient's heart stops or if the patient stops breathing. Option A is correct because a DNR order can indeed be issued by a healthcare provider under certain circumstances, as it is a medical decision. Options B, C, and D are incorrect as they do not accurately reflect the concept of DNR orders and the decision-making process involved in such situations.
