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. Acyclovir (Zovirax) is the agent of choice for which of the following infections?

• A. HIV
• B. AIDS
• C. candida
• D. herpes

Correct answer: D

Rationale: Acyclovir is an antiviral medication specifically effective in treating herpes infections. It works by inhibiting the replication of the herpes virus, shortening the duration of the infection. While Acyclovir can be used in HIV and AIDS patients to treat opportunistic viral infections, it is not a primary drug for managing HIV or AIDS itself. Candida is a type of fungus, and infections caused by Candida are treated with antifungal medications, not antivirals like Acyclovir. Therefore, the correct answer is herpes.

3. Hearing screening of prematurely born infants is an effective means of identifying disease and is an example of:

• A. Primary prevention.
• B. Secondary prevention.
• C. Tertiary prevention.
• D. Disability prevention.

Correct answer: B

Rationale: The correct answer is B: Secondary prevention. Hearing screening for prematurely born infants falls under secondary prevention, which aims to identify and treat a condition in its early stages to prevent further complications. Primary prevention (choice A) focuses on preventing the disease from occurring, while tertiary prevention (choice C) involves managing complications and preventing disability. Choice D, disability prevention, is not a recognized category of prevention. In this context, the screening helps in early identification of hearing loss, allowing for timely intervention to prevent further impairment or complications, aligning with the principles of secondary prevention.

4. Under what circumstances is the legal right to confidentiality of client information waived?

• A. When a court system subpoenas information.
• B. When a family member requests health care information of a client.
• C. When a living will takes effect.
• D. When the client is declared incompetent by the legal system.

Correct answer: A

Rationale: The legal right to confidentiality of client information is waived when a court system subpoenas information. This occurs when information is required for legal proceedings to occur, such as through summonses, court orders, or litigation information necessary for the court. Subpoenas are legal orders that compel the disclosure of information. The other choices do not inherently waive the legal right to confidentiality. A family member's request for health care information would typically require the client's consent or fall under specific legal exceptions. A living will dictates end-of-life care preferences but does not necessarily waive confidentiality. Lastly, the declaration of incompetence may impact decision-making capacity but does not automatically waive confidentiality.

5. A 10-year-old boy has been diagnosed with a congenital heart defect. Which of the following clinical signs does not indicate CHF?

• A. Increased body weight
• B. Elevated heart rate
• C. Lower extremity edema
• D. Compulsive behavior

Correct answer: D

Rationale: Compulsive behavior is not a clinical sign typically associated with congestive heart failure (CHF). CHF commonly presents with symptoms such as increased body weight due to fluid retention, elevated heart rate as the heart works harder to pump blood effectively, and lower extremity edema caused by fluid buildup. While behavioral changes can occur in response to illness, compulsive behavior is not a typical indicator of CHF. Choices A, B, and C are more commonly linked to CHF and should be monitored in patients with this condition.
