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 nurse is assisting a new nursing graduate with organizational skills in delivering client care. The nurse determines that the new nursing graduate needs assistance with time management if the new graduate takes which action?

• A. Gathers supplies before beginning a task
• B. Allows time for unexpected tasks
• C. Prioritizes client needs and daily tasks
• D. Documents task completion and client information at the end of the day

Correct answer: A

Rationale: The correct answer is 'Gathers supplies before beginning a task.' This action indicates a lack of effective time management because gathering supplies before starting a task can lead to inefficiency and time wastage. Effective time management involves organizing tasks efficiently, which includes having all necessary supplies ready before initiating a task. Allowing time for unexpected tasks, prioritizing client needs and daily tasks, and documenting task completion and client information at the end of the day are all essential components of good time management practices. Therefore, the new nursing graduate should focus on improving the timing of supply gathering to enhance time management skills. The other choices are not indicative of poor time management; instead, they demonstrate important aspects of effective time management in client care delivery.

3. 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.

4. When planning play activities for a hospitalized school-age child, a nurse uses Erikson's theory of psychosocial development to select an appropriate activity. The nurse selects an activity that will assist the child in developing which developmental goal?

• A. A sense of industry
• B. Autonomy
• C. A sense of trust
• D. Initiative

Correct answer: C

Rationale: The correct answer is 'A sense of industry.' According to Erikson, the central task of the school-age years is the development of a sense of industry. During this stage, children engage in activities like schoolwork, crafts, chores, hobbies, and sports to develop a sense of competence and productivity. The development of trust is the primary task of infancy, autonomy is the task of toddlerhood, and initiative is the task of the preschool years. Therefore, in this scenario, focusing on fostering a sense of industry aligns with the developmental goals of a school-age child.

5. The mother of a child who weighs 45 lb asks a nurse about car safety seats. The nurse tells the mother to place the child in which car safety seat?

• A. Car safety seat in the back seat in a face-forward position
• B. Booster seat with one of the car's seat belts placed over the child
• C. Booster seat in a rear-facing position in the front seat
• D. Car safety seat in a face-forward position in the front seat

Correct answer: B

Rationale: The correct answer is to place the child in a booster seat with one of the car's seat belts placed over the child. A child needs to remain in a car safety seat until he or she weighs 40 lb. Once the child has outgrown the car safety seat, a booster seat is used. Booster seats are designed to raise the child high enough so that the restraining straps are correctly positioned over the child's chest and pelvis, providing optimal safety. Placing a child in a booster seat in a rear-facing position in the front seat is incorrect as children should not be seated in the front seat due to potential airbag-related injuries. Additionally, car safety seats are used for children weighing less than 40 lb and are placed in the middle of the back seat in a rear-facing position for maximum protection.
