✍️ Sample PCU Questions & Answers
1. What is a common side effect of opioids?
Opioids are potent pain relievers that act on the central nervous system, but they also depress the respiratory drive. This can lead to a decreased respiratory rate and depth, potentially causing hypoventilation and dangerously low oxygen levels. Respiratory depression is a serious and potentially life-threatening side effect that requires careful monitoring, especially with higher doses or in opioid-naive patients.
2. When transferring a PCU patient to a step-down unit, which element of SBAR is MOST critical to communicate regarding patient safety?
SBAR handoffs must include pending diagnostics, safety concerns, and risk for deterioration to ensure the receiving nurse can anticipate and respond to changes.
3. What helps with medication adherence?
Clear written instructions are fundamental for improving medication adherence because they provide a tangible, easily referenceable guide for patients. These instructions should detail the medication name, dosage, frequency, purpose, and any specific administration guidelines or potential side effects. Having this information readily available helps patients remember and correctly follow their prescribed regimen, reducing confusion and errors.
4. A PCU patient on broad-spectrum antibiotics for 7 days develops watery diarrhea with abdominal cramping. Which organism is most likely responsible?
Antibiotic-associated diarrhea after prolonged broad-spectrum antibiotic use is most commonly caused by C. difficile overgrowth following disruption of normal gut flora.
5. In Progressive Care Unit, what is the MOST appropriate response when a potential compliance violation is discovered?
Immediate reporting through established channels with proper documentation ensures timely resolution and maintains the integrity of the compliance program.
6. What is the PRIMARY purpose of documentation & reporting in Progressive Care Unit?
Data and documentation exist primarily to provide accurate, accessible information that supports both decision-making and regulatory compliance.
