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.

Which of the following is responsible for laws mandating the reporting of certain infections and diseases?
- A. Centers for Disease Control and Prevention (CDC)
- B. individual state laws
- C. National Institutes of Health (NIH)
- D. Health and Human Services (HHS)
Correct Answer: B
Rationale: Individual state laws mandate the reporting of infectious diseases. The list of reportable diseases varies from state to state and is overseen by state health departments. While the CDC plays a significant role in disease surveillance, reporting infectious diseases is primarily governed by individual state laws. The CDC's role is to provide support, guidance, and expertise to state health departments. The National Institutes of Health (NIH) primarily focus on biomedical and health-related research, not on mandating disease reporting. Health and Human Services (HHS) is a federal department that oversees various agencies, but the responsibility for mandating disease reporting lies with individual states.
Which direction given to the nursing assistant is most likely to accomplish the task of getting a urine specimen delivered to the lab immediately after collection?
- A. "Make it a stat delivery."?
- B. "Please do it as soon as you can after break."?
- C. "This client is delirious, and we're worried about urinary sepsis."?
- D. "Take this client to the bathroom now and collect a urine specimen from this voiding. Take the specimen to the lab immediately."?
Correct Answer: D
Rationale: Effective delegation depends on clear, concise direction that leaves no room for question or interpretation on the part of the one being delegated to. In this scenario, the most appropriate direction is to ensure the urine specimen is collected promptly and delivered to the lab immediately. Choice A is too vague and does not specify the urgency required. Choice B does not emphasize the immediate need for the specimen to be delivered. Choice C introduces unnecessary medical information that is beyond the scope of a nursing assistant and may cause confusion. Therefore, choice D is the correct answer as it provides clear instructions for immediate action without room for misunderstanding.
Signs of internal bleeding include all of the following except:
- A. painful or swollen extremities
- B. a tender, rigid abdomen
- C. vomiting bile
- D. bruising
Correct Answer: C
Rationale: Vomiting bile is not typically a sign of internal bleeding but is more commonly associated with issues in the gastrointestinal tract. Signs of internal bleeding include painful or swollen extremities, a tender, rigid abdomen, and bruising. Painful or swollen extremities can indicate bleeding from an extremity injury, a tender, rigid abdomen can signal abdominal bleeding, and bruising can result from blood vessel damage. Therefore, the correct answer is 'C: vomiting bile,' as it is not a typical sign of internal bleeding.
The nurse teaching a client about hepatitis and its transmission should explain that one type of hepatitis does not produce a carrier state after its acute phase. Which type is it?
- A. hepatitis A
- B. hepatitis B
- C. hepatitis C
- D. hepatitis D
Correct Answer: A
Rationale: The correct answer is hepatitis A. Hepatitis A does not produce a carrier state after its acute phase. It is transmitted via contaminated water or food through the oral-fecal route and is not blood-borne. Hepatitis B, choice B, can lead to a carrier state where the person remains infectious despite being asymptomatic. Hepatitis C, choice C, can also result in a chronic carrier state. Hepatitis D, choice D, is an incomplete virus that requires hepatitis B to replicate; it does not lead to a carrier state on its own.
When suctioning a client, what is the usual amount of time the nurse should spend for each suction pass?
- A. 2 seconds
- B. 10 seconds
- C. 20 seconds
- D. 30 seconds
Correct Answer: B
Rationale: Ten seconds is the usual amount of time the nurse should spend for each suction pass. Two seconds is not enough time to effectively remove secretions, while 20 and 30 seconds are too long and could lead to hypoxia and tissue trauma. Therefore, the correct choice is 10 seconds, as it strikes a balance between removing secretions adequately and minimizing the risks associated with prolonged suctioning.
