A nurse in a pediatric unit is caring for a group of clients. For which of the following diseases should the nurse implement droplet precautions?

A. Monitoring the insertion site for infection:
Monitoring for infection is important in the long-term care of a client following cardiac catheterization, but it is not the immediate priority. Infection typically develops over time, not in the immediate postprocedure period.

B. Checking for orthostatic hypotension:
Orthostatic hypotension is not typically associated with cardiac catheterization. Instead, hypotension following the procedure would likely result from bleeding or hypovolemia. Monitoring for vital sign changes is important but not specific to orthostatic hypotension in this context.

C. Forcing fluids:
Encouraging fluids is necessary after cardiac catheterization to help flush out contrast dye and prevent nephropathy. However, this action is not the immediate priority compared to managing the risk of bleeding and maintaining hemostasis at the insertion site.

D. Immobilizing the affected extremity:
Immobilizing the extremity used for catheter insertion (usually the femoral artery) is the immediate priority. This action prevents complications such as bleeding, hematoma formation, or disruption of the arterial puncture site. Maintaining hemostasis and ensuring the integrity of the insertion site are critical during the immediate postprocedure period.

A. Serum calcium levels are not directly indicative of hypervolemia.

B. A urine specific gravity of 1.001 indicates dilute urine, which is a common finding in hypervolemia as the kidneys attempt to excrete excess fluid.

C. Serum sodium levels within the normal range (e.g., 138 mEq/L) are not indicative of hypervolemia.

D. Urine pH of 6.1 is within the normal range and does not specifically indicate hypervolemia.
