Difficulty: Very hardReduction of Risk Potential

A practical nurse (PN) is monitoring a client who is 4 hours post-percutaneous coronary intervention (PCI) via the right femoral artery approach. Which of the following assessment findings should the PN identify as an impending complication requiring immediate escalation to the registered nurse (RN)? Select all that apply.

  1. The client reports a new onset of constant, deep lower back pain.Answer
  2. The client's resting heart rate gradually increased from 76 to 112 beats per minute over the past two hours.Answer
  3. The client exhibits new-onset paresthesia and numbness in the right toes.Answer
  4. D
    The cardiac monitor displays occasional premature ventricular contractions (PVCs) at a rate of two per hour.
  5. E
    A morning serum magnesium laboratory result of 1.9 mEq/L.
  6. F
    The assistive personnel (AP) reports the client voided 150 mL of clear, yellow urine over the past three hours.

Answer

The findings that require immediate escalation are the new onset of deep lower back pain, the gradually increasing heart rate, and the new-onset paresthesia in the toes.
Following a femoral PCI, clients are at high risk for retroperitoneal hemorrhage (indicated by flank or lower back pain), hypovolemic shock (indicated by a steadily increasing heart rate), and distal arterial occlusion (indicated by neurovascular changes like paresthesia). These findings require immediate escalation to prevent life-threatening deterioration or limb loss.

Step-by-Step Solution

1
Analyze the client's clinical context and risk factors.
The client is 4 hours post-PCI via the right femoral artery, placing them at high risk for vascular complications such as retroperitoneal bleeding, arterial occlusion, and hemorrhagic shock.
Identifying the procedure and access site directs the focus of the risk assessment.
2
Evaluate each finding for signs of bleeding or shock.
Deep lower back pain indicates retroperitoneal bleeding. A gradual heart rate increase to 112 beats per minute is an early compensatory mechanism for volume loss.
Internal bleeding may not be externally visible at the insertion site and must be detected through vital sign trends and referred pain.
3
Evaluate findings for signs of neurovascular compromise.
New-onset paresthesia and numbness in the right toes indicate impaired distal blood flow.
Arterial thrombosis or hematoma compression at the femoral site can obstruct blood flow to the lower extremity, presenting as one or more of the '6 Ps'.
4
Differentiate expected or benign findings from true emergencies.
A magnesium level of 1.9 mEq/L, rare PVCs, and a urine output of 50 mL/hr are all within expected or safe limits and do not require immediate escalation.
Recognizing normal parameters prevents unnecessary escalation and focuses nursing care on genuine priorities.

Key Concept
