### Chapter 1: The Critical Care Environment and Professional Issues —
Questions 1–10
**Q1.** A critical care nurse is assessing a patient in the ICU. Which factor is
most important in preventing ventilator-associated pneumonia (VAP)?
A. Keeping the head of the bed elevated at 30–45 degrees
B. Administering prophylactic antibiotics
C. Suctioning every 2 hours
D. Using a closed suction system
,**Correct Answer: A**
**Rationale:** Elevating the head of the bed to 30–45 degrees reduces the risk
of aspiration and is a key measure in preventing VAP.
---
**Q2.** A critical care nurse is caring for a patient with an arterial line. Which
action is essential to prevent infection?
A. Changing the tubing every 24 hours
B. Using sterile technique during insertion and maintenance
C. Flushing the line with tap water
D. Keeping the line open to air
**Correct Answer: B**
**Rationale:** Sterile technique is essential during insertion and maintenance
of arterial lines to prevent bloodstream infections.
---
**Q3.** A critical care nurse is reviewing the AACN Synergy Model. What is
the central concept of this model?
A. Patient characteristics drive nurse competencies
B. Nurse characteristics drive patient outcomes
C. The environment drives patient outcomes
,D. Technology drives nurse competencies
**Correct Answer: A**
**Rationale:** The AACN Synergy Model matches patient characteristics with
nurse competencies to optimize outcomes.
---
**Q4.** A critical care nurse is caring for a patient with a pulmonary artery
catheter. Which finding indicates a complication?
A. Pulmonary artery occlusion pressure (PAOP) of 12 mm Hg
B. Central venous pressure (CVP) of 8 mm Hg
C. Ventricular dysrhythmias during insertion
D. Cardiac output of 5 L/min
**Correct Answer: C**
**Rationale:** Ventricular dysrhythmias are a common complication during
pulmonary artery catheter insertion and require immediate intervention.
---
**Q5.** A critical care nurse is assessing a patient for delirium. Which tool is
most appropriate?
A. CAM-ICU
, B. GCS
C. NIHSS
D. RASS
**Correct Answer: A**
**Rationale:** The CAM-ICU is the most validated tool for assessing delirium
in ICU patients. RASS assesses sedation, not delirium.
---
**Q6.** A critical care nurse is reviewing evidence-based practice. Which
intervention reduces the risk of central line-associated bloodstream infection
(CLABSI)?
A. Using chlorhexidine for skin antisepsis
B. Changing the dressing every 7 days
C. Using femoral site for insertion
D. Avoiding maximal sterile barrier precautions
**Correct Answer: A**
**Rationale:** Chlorhexidine skin antisepsis is a key component of CLABSI
prevention bundles.
