CDN Complications and Emergency Management 3

Question 1

Which vital sign change during hemodialysis should prompt the nurse to assess for hypovolemia first?

Accepted Answer

Blood pressure drop of more than 20 mmHg systolic

Answer

A systolic blood pressure drop of more than 20 mmHg from baseline during dialysis is a primary indicator of intradialytic hypotension and requires immediate assessment for hypovolemia.

Question 2

What is the most common infectious complication in hemodialysis patients?

Accepted Answer

Vascular access-related bloodstream infection (VRBI)

Answer

Vascular access-related bloodstream infections are the most common and serious infectious complication in hemodialysis patients, most often caused by Staphylococcus aureus.

Question 3

A patient on dialysis is found unresponsive with a blood glucose of 38 mg/dL. After administering glucose, what additional assessment is critical?

Accepted Answer

Evaluate dialysate glucose concentration and assess medication regimen for hypoglycemic agents

Answer

After treating hypoglycemia, the nurse must identify the cause — some dialysate formulations contain no glucose, and patients on insulin or sulfonylureas are at increased risk during treatment.

Question 4

What is the primary goal of emergency ultrafiltration in a dialysis patient presenting with acute pulmonary edema?

Accepted Answer

Rapidly remove excess fluid to relieve respiratory compromise

Answer

Emergency isolated ultrafiltration rapidly removes excess fluid from the overloaded patient to relieve pulmonary edema and restore respiratory function.

Question 5

Which cardiovascular complication is the leading cause of death in hemodialysis patients?

Accepted Answer

Sudden cardiac death and cardiovascular disease

Answer

Cardiovascular disease, particularly sudden cardiac death from arrhythmia and coronary artery disease, accounts for approximately 40–50% of deaths in ESRD patients on hemodialysis.
