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 client scheduled for surgery tells the nurse that he signed an informed consent for the surgical procedure but was never told about the risks of the surgery. The nurse serves as the client's advocate by undertaking which action?

• A. Reassuring the client that the risks are minimal
• B. Noting in the client's record that the client was not told about the risks of the surgery
• C. Writing a note on the front of the client's record so that the surgeon will see it when the client arrives in the operating room
• D. Informing the surgeon verbally about the lack of information provided to the client

Correct answer: B

Rationale: A nurse serves as a client advocate by protecting the client's right to be informed and to participate in decisions regarding care. In this scenario, the nurse should document in the client's record that the client was not informed about the risks of the surgery. This action ensures that the issue is officially noted and can be addressed by the healthcare team. Reassuring the client that the risks are minimal is incorrect because it dismisses the client's concerns and does not address the lack of information provided. Writing a note on the client's chart to inform the surgeon is not as effective as ensuring that the issue is officially documented in the client's record, where it can be reviewed and addressed by the healthcare team. Informing the surgeon verbally is not as reliable as documenting the concern in the client's record, which provides a formal and lasting record for review and follow-up.

3. The client is going for surgery and mentions their religious objection to blood transfusions. Which of the following responses would be most appropriate?

• A. "I can ask pastoral care to send someone to speak with you about this concern since it would not be safe to refuse a blood transfusion."?
• B. "I understand, and you have the right to refuse blood transfusions."?
• C. "While I understand, if there is excessive bleeding during surgery, we may need to transfuse blood to stabilize you."?
• D. "I have received a blood transfusion before, and I do not think you understand the risks versus the benefits of refusing this."?

Correct answer: B

Rationale: The most appropriate response is, '"I understand, and you have the right to refuse blood transfusions."? This answer shows respect for the client's autonomy and religious beliefs. It is crucial for healthcare providers to acknowledge and support a patient's decision-making regarding their care, even if it conflicts with medical advice. Option A is not ideal as it might seem dismissive of the client's beliefs. Option C introduces a potential negative outcome of refusing a blood transfusion, which could induce fear or coercion. Option D is inappropriate because it implies judgment and does not uphold the client's autonomy.

4. What is the term for the tendency of a drug to combine with its receptor?

• A. potency
• B. efficacy
• C. kinetics
• D. affinity

Correct answer: D

Rationale: The correct answer is 'affinity.' Affinity refers to the close relationship or mutual attraction between a drug and its receptor, indicating the strength of the drug-receptor bonding. Potency (Choice A) is related to the dose of a drug needed to produce a specific effect. Efficacy (Choice B) refers to a drug's ability to generate the desired effect. Kinetics (Choice C) deals with forces affecting the motion of material bodies or changes in a system, which is not directly associated with the bonding between a drug and its receptor.

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.
