The nurse is conducting a staff in-service on renal ultrasounds. Which statement describes this diagnostic test?
- A. Computed tomography uses external radiation to visualize the renal system.
- B. Visualization of the renal system is accomplished without exposure to radiation or radioactive isotopes.
- C. Contrast medium and x-rays allow for visualization of the renal system.
- D. External radiation for x-ray films is used to visualize the renal system, before, during, and after voiding.
Correct Answer: B
Rationale: Renal ultrasound is a non-invasive imaging technique that uses high-frequency sound waves to produce images of the kidneys and surrounding structures. Unlike computed tomography (CT) scans (Choice A) or intravenous pyelograms (Choice C) which may involve exposure to radiation or contrast medium, renal ultrasounds do not expose the patient to radiation or radioactive isotopes, making it a safe option for imaging the renal system. Ultrasounds are commonly used to assess kidney size, detect kidney stones, evaluate blood flow to the kidneys, and diagnose various renal conditions, such as hydronephrosis or renal cysts.

A patient has iron deficiency anemia. Which of the following foods will best help provide dietary iron?
- A. Fresh fruits
- B. Dairy products
- C. Lean red meats
- D. Breads and cereals
Correct Answer: C
Rationale: Lean red meats are a great source of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based sources. Heme iron from animal products is particularly beneficial for individuals with iron deficiency anemia as it can help increase their iron levels more effectively. In addition to lean red meats, other animal sources of heme iron include poultry and fish.
Which of the following settings is most therapeutic for an agitated head-injured patient?
- A. A day room with family visitors and variety of caregivers
- B. A semiprivate room with one or two consistent caregivers
- C. A ward with other head-injured patients and volunteers to assist with needs
- D. A hallway near the nurse's station with adequate sensory stimulation
Correct Answer: B
Rationale: For an agitated head-injured patient, the most therapeutic setting would be a semiprivate room with one or two consistent caregivers. Consistency and familiarity can help reduce agitation and promote a sense of security for the patient. A quieter environment with fewer stimuli can also help in managing agitation and promoting a sense of calmness. By having consistent caregivers, the patient can build trust and feel more comfortable, which can contribute to their overall well-being and recovery. It is essential to minimize external factors that could contribute to further agitation, making a semiprivate room with consistent caregivers the most optimal setting for an agitated head-injured patient.
What is the single most important factor to consider when communicating with children?
- A. The child's physical condition
- B. Presence or absence of the child's parent
- C. The child's developmental level
- D. The child's nonverbal behaviors
Correct Answer: C
Rationale: The single most important factor to consider when communicating with children is the child's developmental level. Understanding where a child is at in terms of cognitive, emotional, and social development is crucial for effective communication. By considering the child's developmental level, you can adjust your language, tone, and content to suit their abilities and needs. This ensures that the child can understand and engage with the communication effectively. Communication that aligns with a child's developmental stage promotes better comprehension, engagement, and relationship-building.
Which of the following is a nurse patient care role in the preoperative phase?
- A. Obtaining preoperative orders
- B. Offering emotional support
- C. Explaining the surgical procedure
- D. Providing informed consent
Correct Answer: A
Rationale: In the preoperative phase, one of the key roles of a nurse in patient care is to obtain preoperative orders. This involves ensuring that all necessary tests, medications, and procedures are in place before the surgery is performed. By obtaining preoperative orders, the nurse ensures that the patient is adequately prepared for the surgical procedure and that any potential risks or complications are minimized. This role requires attention to detail, clear communication with the healthcare team, and a thorough understanding of the patient's individual needs and medical history.
The clinic is lending a federally approved car seat to an infant's family. The nurse should explain that the safest place to put the car seat is:
- A. front facing in back seat.
- B. rear facing in back seat.
- C. front facing in front seat with air bag on passenger side.
- D. rear facing in front seat if an air bag is on the passenger side.
Correct Answer: B
Rationale: Placing the car seat rear facing in the back seat is the safest option for an infant. Rear-facing car seats provide the best protection for a baby's head, neck, and spine in the event of a crash. It is recommended to keep infants in a rear-facing position until they reach the maximum weight or height limit allowed by the car seat manufacturer. Placing the car seat in the front seat, especially with an active airbag, can be dangerous for an infant due to the force of deployment in case of an accident. It is important to follow the guidelines for safe car seat use to ensure the protection and well-being of the child.
