Nursing QUESTION #9242

Question 3262

A patient in the ICU is on continuous renal replacement therapy (CRRT). The Charge Nurse notices the effluent bag is not filling and the circuit pressure alarms are high. What is the MOST likely problem?

Dialysate flow rate is too high
Circuit clotting — filter obstruction✔️
Anticoagulation is excessive
Patient is in fluid overload

Correct Answer Logic:

Correct Answer: B — Circuit clotting

CRRT circuit clotting is the most common complication of CRRT in ICU, especially in patients with:

Hypercoagulable states
Inadequate anticoagulation
Low blood flow rates
High hematocrit

Signs of circuit clotting:

High filter/transmembrane pressure alarms
Reduced or absent effluent output
Dark color of blood in circuit
Frequent circuit 'down' time

Prevention strategies:

Regional citrate anticoagulation (RCA): First-line anticoagulation in CRRT (KDIGO 2012)
Systemic heparin infusion (if no bleeding risk)
Maintain blood flow rate $\geq 150-200 \text{ mL/min}$
Predilution mode (dilutes blood before filter)

When clotting occurs, the circuit must be changed and anticoagulation reassessed.

CISA QUESTION #1723

Question 3263

Among the different assurance mechanisms available, which one is considered acceptable for external purposes, including regulatory licensing and third-party reliance?

Independent audit✔️
Assessment
External audit
Internal audit

Correct Answer Logic:

An independent audit is the gold standard for external reliance because it is conducted by a qualified auditor who has no conflicts of interest with the auditee. Internal audits are often limited by the auditor's employment relationship, which can compromise objectivity. External audits may be constrained in scope by client preferences. Assessments are too informal for licensing or regulatory purposes. Only the independent audit provides the level of rigour and objectivity required for external use.
