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. A 51-year-old client with amyotrophic lateral sclerosis (Lou Gehrig disease) is admitted to the hospital because his condition is deteriorating. The client tells the nurse that he wants a do-not-resuscitate (DNR) order. The nurse should provide the client with which information?

• A. Oral consent is not sufficient, and the client's request will be honored by all healthcare providers.
• B. Consent must be obtained from the family.
• C. The DNR request should be discussed with the healthcare provider, who will write the order.
• D. The healthcare provider makes the final decision about a DNR request.

Correct answer: C

Rationale: When a client requests a DNR order, the nurse should contact the healthcare provider so that the provider may discuss the request with the client. A DNR order should be written, not verbal, following agency and state guidelines. Therefore, the correct answer is that the DNR request should be discussed with the healthcare provider, who will write the order. Option A is incorrect as oral consent is not sufficient for a DNR order. Option B is incorrect because the client, not the family, has the authority to request a DNR order. Option D is incorrect because the healthcare provider discusses the request with the client but does not make the final decision.

3. Which is the correct order regarding the hierarchy of members of the nursing team from least authority to highest authority?

• A. LPN, staff nurse, charge nurse, nurse manager
• B. Staff nurse, LPN, nurse manager, charge nurse
• C. LPN, staff nurse, charge nurse, nurse manager
• D. LPN, staff nurse, charge nurse, nurse manager

Correct answer: C

Rationale: The correct hierarchy order from least to highest authority in the nursing team is LPN (Licensed Practical Nurse), staff nurse, charge nurse, and nurse manager. LPNs have the least authority, followed by staff nurses who are supervised by charge nurses. Nurse managers oversee the charge nurses, making them the highest authority in this hierarchy. Therefore, choices A, B, and D are incorrect as they do not follow the correct order of authority within the nursing team.

4. Which of the following ethnic groups is at highest risk in the United States for pesticide-related injuries?

• A. Native American
• B. Asian-Pacific
• C. Norwegian
• D. Hispanic

Correct answer: D

Rationale: The correct answer is 'Hispanic.' Hispanic individuals in the United States are at a higher risk for pesticide-related injuries due to their representation among migrant workers in agricultural settings. This exposure to pesticides in their work environments increases their risk compared to other ethnic groups. Choice A, 'Native American,' although indigenous populations may face environmental health disparities, the higher risk in this context is among Hispanic individuals. Choice B, 'Asian-Pacific,' and Choice C, 'Norwegian,' do not have the same level of exposure to pesticides as Hispanic migrant workers, making them less susceptible to pesticide-related injuries.

5. Which of the following is not an indication for pelvic ultrasonography?

• A. to measure uterine size
• B. to detect multiple pregnancies
• C. to measure renal size
• D. to detect foreign bodies

Correct answer: C

Rationale: Pelvic ultrasonography is commonly used to assess various conditions. Choices A, B, and D are all valid reasons for performing pelvic ultrasonography. Measuring uterine size helps evaluate conditions like fibroids, while detecting multiple pregnancies is essential for prenatal care. Furthermore, identifying foreign bodies can aid in diagnosing certain conditions. However, assessing renal size is typically not a primary reason for pelvic ultrasonography, making choice C the correct answer.
