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:

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.

Correct Answer: A

Rationale: Option A, "Let him know it is all right to cry," is the most appropriate intervention for a four-year-old like Brian who appears to be upset by hospitalization. Acknowledging and validating his emotions, including the possibility of crying, is important for his emotional well-being. By letting Brian know it is okay to express his feelings, he can feel supported and understood during a potentially difficult time. It is crucial for children to feel that their emotions are valid and accepted, promoting their emotional resilience and coping skills. This approach fosters trust and comfort, helping Brian navigate his emotions in a healthy way.

Correct Answer: B

Rationale: Smokeless tobacco refers to tobacco products that can be used without being smoked. These products usually come in the form of snuff, chewing tobacco, or dissolvable tobacco products. While smokeless tobacco does not involve the inhalation of smoke, it is still proven to be carcinogenic. The most significant health risk associated with smokeless tobacco is the potential to develop various types of cancer, including oral, esophageal, and pancreatic cancer. Therefore, it is crucial to understand that using smokeless tobacco is not a safe alternative to cigarette smoking, as it still poses serious health risks.

Correct Answer: B

Rationale: Option B is descriptive of attention deficit hyperactivity disorder (ADHD). Manifestations of ADHD can significantly impact the child's life, but are most noticeable in the classroom setting. Children with ADHD may struggle with paying attention, staying organized, controlling impulsive behavior, and following instructions in the school environment. While symptoms can also affect other areas of life, such as social interactions and familial relationships, they are typically most prominently displayed in the structured school setting, making it easier to recognize and diagnose the disorder.

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.
