A nurse is caring for a child who is postoperative following surgical correction of Tetralogy of Fallot. Which of the following findings should the nurse identify as an indication of heart failure?

Choice A reason: Obtaining written consent from the client is appropriate as adolescents are entitled to confidential care for STIs. This respects the client's autonomy and privacy.

Choice B reason: Contacting the client's parents may not be necessary unless the adolescent is under the age specified by law for independent consent. It could also breach confidentiality.

Choice C reason: Postponing the testing could delay diagnosis and treatment, which is not in the best interest of the client. Immediate testing is important for health and well-being.

Choice D reason: Requesting verbal consent from the social worker is not appropriate as the consent should come directly from the client or their legal guardian, if required.

Choice A reason: A 24-gauge catheter is appropriate for a small and fragile vein of a 12-month-old infant. It minimizes the risk of damaging the vein and ensures the comfort of the infant during IV therapy.

Choice B reason: Starting an IV in the infant's foot is not the first choice due to the risk of movement dislodging the catheter. The hand or the antecubital fossa are preferred sites for IV insertion in infants.

Choice C reason: While it is important to cover the IV insertion site, an opaque dressing is not necessary. A transparent dressing is preferred as it allows for continuous visibility of the site for signs of infection or phlebitis.

Choice D reason: The IV site should not be routinely changed every 3 days. It should be changed based on clinical indications such as signs of infection, infiltration, or phlebitis, or if the IV becomes dislodged.
