A nurse is collecting data from a client about range-of-motion for various joints. Which of the following should the nurse identify as an example of a ball and socket joint?

A. "I should keep my baby rear-facing in the car seat until she is 2 years old.": This is correct. The American Academy of Pediatrics recommends that infants and toddlers remain in a rear-facing car seat until they are at least 2 years old or until they reach the height and weight limits specified by the car seat manufacturer. Rear-facing provides the best protection for the baby's head, neck, and spine in the event of an accident.

B. "I should position the car seat's retainer clip at the level of my baby's belly button.": This is incorrect. The retainer clip should be positioned at armpit level, not at the belly button. This ensures the harness fits snugly and securely around the baby.

C. "I should enable the airbag when my baby is in the front seat of the car.": This is incorrect. Airbags should never be enabled when a baby is sitting in the front seat, as they can cause injury in the event of a collision. The baby should always be seated in the back seat of the car, as it is the safest location.

D. "I should place my baby in the car seat at a 90-degree angle.": This is incorrect. The car seat should be reclined at an angle of approximately 45 degrees to ensure the baby’s head does not fall forward, which could compromise breathing. A 90-degree angle is too upright and may be unsafe for a newborn.

A. "A nurse discusses a client's postoperative complications during shift report.": This is not a breach of confidentiality if the information is shared within the context of a healthcare team for the purpose of providing care. Confidentiality is maintained as long as the information is shared appropriately.

B. "A facility risk manager includes information from a client's medical record in a when report.": This is also not necessarily a breach of confidentiality if the report is used for quality improvement, risk management, or other institutional purposes where confidentiality protocols are followed.

C. "A nurse tells the chaplain that a client has a new diagnosis of cancer.": This is a breach of confidentiality. Information should only be shared with others involved in the patient's care or if the patient has given explicit consent. Discussing a client's diagnosis with a chaplain or anyone not directly involved in the care plan is an unauthorized disclosure.

D. "A social worker reads a client's chart as a follow-up to a requested consultation.": This is not a breach of confidentiality if the social worker is following established protocols for patient care and is authorized to access the client's medical records for consultation purposes.
