A nurse is providing teaching to the guardian of an infant who has heart failure. Which of the following instructions should the nurse include?

A. Use simple diagrams to explain the procedure. Children benefit from visual aids to help them understand medical procedures. Using simple diagrams can help the child visualize what will happen during the tonsillectomy in a non-threatening way and make the process less intimidating.

B. Indicate on a stuffed animal where the procedure will be performed. While a stuffed animal might be useful for younger children, a 9-year-old is more likely to benefit from a visual aid that is more aligned with their cognitive and developmental level. Simple diagrams or pictures would be more appropriate for this age group.

C. Provide teaching immediately before the procedure. It is more effective to provide teaching well before the procedure to allow the child time to process and ask questions. Immediate preoperative teaching might lead to increased anxiety and may not allow enough time for the child to fully understand.

D. Discuss the benefits of the procedure. While it is important to acknowledge the purpose of the procedure, focusing on the benefits alone might not address the child's concerns and anxieties about the procedure. Explaining the procedure in a straightforward and understandable manner, without overemphasizing the benefits, is usually more effective in reducing anxiety.

A. "Pinpoint pupils." A subdural hematoma typically causes unequal or dilated pupils due to increased intracranial pressure (ICP), rather than pinpoint pupils, which are more commonly associated with opioid toxicity or pontine damage.

B. "Sunken anterior fontanel." A sunken fontanel is a sign of dehydration. In cases of increased ICP, as seen with a subdural hematoma, the anterior fontanel is more likely to be bulging.

C. "Hypertonia." Neurological changes can occur, but hypotonia (decreased muscle tone) is more common in infants with increased ICP rather than hypertonia (increased muscle tone).

D. "Vomiting." Vomiting is a classic sign of increased ICP in infants, which occurs due to the pressure on the brainstem. Other symptoms may include irritability, a bulging fontanel, seizures, and lethargy.
