Final answer:
The client's statement about using an ice bag for bleeding suggests a need for further teaching; correct post-cardiac catheterization care involves applying direct pressure and seeking medical attention for complications.
Step-by-step explanation:
The question pertains to the instructions given to a patient after cardiac catheterization. When considering the statements made by the client post-procedure, the statement indicating a need for further teaching is "If bleeding occurs, I should place an ice bag on the site for 10 minutes." After a cardiac catheterization, direct pressure is the primary method for controlling bleeding at the catheter insertion site, not cold therapy. Furthermore, instructing a patient to self-manage a potential complication such as bleeding by simply applying an ice bag is inadequate; they should be instructed to seek medical attention immediately.
Other statements such as avoiding straining and lifting heavy objects for a day, calling the doctor if the patient's temperature goes above 101°F, and discussing return to work with the doctor are appropriate and indicate accurate understanding of post-procedural care.
