Difficulty: MediumReduction of Risk Potential

An adult client is transferred to the cardiac step-down unit after a percutaneous coronary intervention utilizing the right femoral artery approach. During routine monitoring, the nurse notes the client's blood pressure has trended downward from 134/82 mm Hg to 106/64 mm Hg within the past hour. Simultaneously, the client complains of sudden, deep pain in the lower back. Which initial action should the nurse perform?

  1. Examine the right groin insertion site, flank, and retroperitoneal area for swelling or bruising.Answer
  2. B
    Raise the head of the bed to a 45-degree angle to alleviate the client's lower back discomfort.
  3. C
    Administer the prescribed PRN analgesic medication to treat the reported back pain.
  4. D
    Direct the unlicensed assistive personnel to immediately recheck the vital signs in 15 minutes.

Answer

The correct action is to examine the right groin insertion site, flank, and retroperitoneal area for swelling or bruising.
The combination of a dropping blood pressure and new-onset lower back pain following a femoral artery procedure strongly suggests retroperitoneal bleeding. Blood tracking into the retroperitoneal space irritates nerves, causing back or flank pain, while the loss of circulating volume causes hypotension. The nurse's first priority is to directly assess the insertion site, flank, and retroperitoneal area for a hematoma, ecchymosis, or swelling to confirm this life-threatening complication.

Step-by-Step Solution

1
Analyze the client's clinical presentation.
The client has a downward trending blood pressure and new-onset lower back pain following a femoral artery puncture.
Identifying these acute changes is crucial for recognizing potential post-procedural complications.
2
Correlate the findings with potential procedural complications.
Hypotension combined with back or flank pain are classic early indicators of retroperitoneal bleeding, a severe risk after femoral cardiac catheterization.
Blood can pool in the retroperitoneal space without obvious external bleeding at the immediate puncture site.
3
Determine the safest priority nursing intervention.
The nurse must immediately physically assess the puncture site, flank, and retroperitoneal area to confirm bleeding.
Direct assessment provides the necessary clinical data to confirm hemorrhage and implement life-saving interventions before notifying the provider.
