A nurse is counseling a client whose partner has recently died. The client reports continuing to cook their partner's favorite meals. The nurse should identify that the client is using which of the following defense mechanisms?

A. Monitoring the insertion site for infection: Infection is a potential complication, but it is not an immediate concern right after the procedure. Signs of infection develop hours to days later, so this assessment is important but not the priority in the immediate postprocedure period.

B. Checking for orthostatic hypotension: Orthostatic changes are not typically the most urgent issue immediately after cardiac catheterization. The client is usually kept in a supine position, which limits the risk of sudden blood pressure drops. While monitoring vital signs is important overall, vascular site integrity takes precedence at this stage.

C. Forcing fluids: Increasing fluid intake is encouraged postprocedure to promote excretion of contrast dye and protect kidney function. However, this intervention does not address the primary acute risk, which is bleeding from the catheter insertion site. Fluids are helpful but not the most immediate priority.

D. Immobilizing the affected extremity: The insertion site, often in the femoral artery, is at high risk for bleeding or hematoma formation immediately after the procedure. Immobilizing the extremity helps maintain pressure at the site and prevents disruption of the arterial puncture. This action directly reduces the risk of hemorrhage, making it the top priority.

A. A series of four hepatitis vaccines is recommended: This is incorrect. Vaccines are available for hepatitis A and hepatitis B only, and they are not given as a single four-vaccine series to prevent all viral hepatitis types.

B. Hepatitis B is transmitted by contaminated food: This describes hepatitis A, not hepatitis B. Hepatitis B is transmitted through blood, sexual contact, and perinatal exposure.

C. Chronic hepatitis can lead to renal cell cancer: Chronic hepatitis (especially B and C) increases the risk of hepatocellular carcinoma (liver cancer), not renal cell cancer.

D. Individuals with a history of viral hepatitis are not eligible to donate blood due to the risk of transmitting hepatitis viruses to recipients. Blood donation screening excludes donors with past hepatitis infection to ensure blood safety.
