INTRODUCTION
The Progressive Care Certified Nurse (Knowledge-Based) assessment is a
comprehensive examination designed to validate the proficiency of nurses providing
care to acutely ill adult patients in non-bedside roles. This exam evaluates the
clinician’s ability to synthesize complex physiological data, apply evidence-based
interventions, and ensure patient safety within the progressive care environment. The
,assessment utilizes a blend of foundational theory and scenario-based questions to
challenge the candidate’s critical thinking and clinical decision-making skills. By
focusing on real-world applications and professional standards, this exam ensures
that the practitioner possesses the specialized knowledge necessary to influence
patient outcomes and lead multidisciplinary teams effectively.
SECTION ONE: QUESTIONS 1–100
1. A patient with a history of heart failure presents with sudden onset of orthopnea
and crackles at the lung bases. Which of the following is the most likely
physiological cause?
A. Decreased systemic vascular resistance
B. Increased pulmonary capillary wedge pressure
C. Decreased right ventricular afterload
D. Increased glomerular filtration rate
🟢 B. Increased pulmonary capillary wedge pressure
🔴 RATIONALE: Heart failure exacerbations lead to increased left ventricular end-
diastolic pressure, which reflects back into the pulmonary vasculature, increasing
pulmonary capillary wedge pressure and causing fluid to shift into the alveoli.
, 2. Which medication is considered the first-line treatment for a patient
experiencing symptomatic sinus bradycardia?
A. Amiodarone
B. Epinephrine
C. Atropine
D. Digoxin
🟢 C. Atropine
🔴 RATIONALE: Atropine is an anticholinergic drug that increases the heart rate by
blocking the vagus nerve's influence on the SA node, making it the primary choice for
symptomatic bradycardia.
3. A patient with Chronic Obstructive Pulmonary Disease (COPD) is receiving
oxygen therapy. What is the target SpO2 range for this patient to prevent CO2
retention?
A. 94%–98%
B. 88%–92%
C. 98%–100%
D. 85%–88%
, 🟢 B. 88%–92%
🔴 RATIONALE: In patients with chronic CO2 retention, high levels of supplemental
oxygen can blunt the hypoxic drive, leading to further respiratory depression;
therefore, a lower target saturation is maintained.
4. During the assessment of a patient with a suspected abdominal aortic aneurysm
(AAA), which finding is most indicative of a pending rupture?
A. Increased bowel sounds
B. Severe back or flank pain
C. Hypertension
D. Bradycardia
🟢 B. Severe back or flank pain
🔴 RATIONALE: New or worsening back or flank pain in a patient with a known or
suspected AAA often indicates that the aneurysm is expanding or leaking, signaling
an impending rupture.
5. A patient is admitted with Diabetic Ketoacidosis (DKA). Which electrolyte
imbalance is of greatest concern during the initial phase of insulin
administration?
