CAPA Evidence-Based Practice in PACU 2

Question 1

According to evidence-based guidelines, which intervention most effectively reduces postoperative nausea and vomiting (PONV) in high-risk ambulatory patients?

Accepted Answer

Multimodal prophylaxis combining two or more antiemetic agents

Answer

Evidence supports multimodal PONV prophylaxis using two or more agents from different classes for high-risk patients.

Question 2

When appraising a research study for PACU practice change, which study design provides the highest level of evidence?

Accepted Answer

Randomized controlled trial

Answer

Randomized controlled trials are considered the gold standard for evidence quality in clinical research hierarchies.

Question 3

An evidence-based practice protocol recommends early ambulation post-PACU discharge. Which outcome does this primarily target?

Accepted Answer

Prevention of deep vein thrombosis and pulmonary embolism

Answer

Early ambulation is evidence-based for reducing venous stasis and the risk of DVT and PE in postoperative patients.

Question 4

The ASPAN evidence-based practice model recommends that nurses grade evidence before implementing a practice change. What does a Grade A recommendation signify?

Accepted Answer

Evidence from at least one well-designed RCT or systematic review

Answer

Grade A recommendations are supported by strong evidence from randomized controlled trials or systematic reviews.

Question 5

Which outcome measure is most appropriate for evaluating evidence-based pain management effectiveness in the PACU?

Accepted Answer

Patient-reported pain scores combined with functional assessments

Answer

Combining patient-reported pain scores with functional status provides a more comprehensive, evidence-based measure of pain management.
