A nurse is assisting in the care of a client who is taking chlorpromazine. Which of the following findings indicates a therapeutic effect medication?

A) Rolls from back to abdomen: Rolling from back to abdomen is a typical developmental milestone for a 4-month-old infant. By this age, infants usually have increased muscle strength and coordination, allowing them to start rolling over. This movement helps build their core strength, which is important for later developmental milestones like sitting up and crawling.

B) Moves objects to mouth: It is common for a 4-month-old to move objects to their mouth as they begin exploring the world around them. This action is a key part of sensory development and helps infants develop their hand-to-mouth coordination. Additionally, this behavior assists in teething and the development of oral motor skills.

C) Anterior fontanel closed: The anterior fontanel normally closes between 12 to 18 months of age. If it is closed at 4 months, it may suggest abnormal cranial growth, such as craniosynostosis, where the sutures of the skull close too early. This could lead to increased pressure on the brain, which can cause developmental delays or other complications, so the provider should be notified for further assessment.

D) Posterior fontanel closed: The posterior fontanel typically closes by 2 to 3 months of age. If it is closed by 4 months, it is completely normal and indicates proper cranial development. The closing of the posterior fontanel helps ensure the skull's bones are fusing together as expected, and it does not raise any concerns at this stage.

A) "The client should use a hair dryer on a warm setting to relieve itching inside the cast.": Using a hair dryer on a warm setting to relieve itching inside the cast is not recommended because it could potentially lead to burns or skin irritation. The client should avoid inserting objects inside the cast to scratch, as this could damage the skin or cause an infection.


B) "The client can shower with the cast after 24 hr.": A plaster cast is not waterproof, and the client should avoid getting it wet. Although the cast may feel dry on the outside after 24 hours, it typically takes about 48 hours or longer for a plaster cast to fully dry and harden. Showering with a plaster cast is not safe, as moisture could cause skin irritation or lead to the development of sores or infection.

C) "The client’s extremity should be elevated after the cast is applied.": Elevating the extremity after a cast is applied is a key teaching point to help reduce swelling and improve circulation. This is especially important during the first 24 to 48 hours after cast application. Elevation helps to prevent or manage swelling, which can be a common complication after an injury and cast application.

D) "The client should keep the cast covered until it is dry.": While it is important to keep a cast clean and dry during the drying process, the cast should not be covered with plastic or other materials that could trap moisture. The cast needs air circulation to dry properly, and covering it could lead to the cast becoming too moist, increasing the risk of skin issues or infection.
