IntroductionWelcome to the comprehensive practice assessment
designed specifically for progressive care nursing professionals. This
evaluation serves as a rigorous preparatory tool to measure clinical
proficiency, diagnostic reasoning, and evidence-based practice across
multiple critical care subspecialties. The assessment rigorously tests
essential skills and knowledge related to patient surveillance, complex
intervention management, and interdisciplinary collaboration. Featuring a
robust mix of multiple-choice and complex scenario-based items, the
structure emphasizes real-world application, rapid prioritization, and
sound clinical decision-making. By engaging with these high-acuity
scenarios, practitioners will sharpen their capacity to anticipate
complications and deliver exceptional patient-centered care.
A progressive care unit nurse is monitoring a patient admitted with
an acute anterior wall myocardial infarction. Telemetry suddenly
displays short runs of nonsustained ventricular tachycardia. Which
of the following laboratory values should the nurse check
immediately as a potential precipitating factor?
A. Serum creatinine
B. Serum potassium
C. Blood urea nitrogen
D. Serum sodium
🔴 Explanation: Hypokalemia is a frequent and dangerous electrolyte
disturbance in acute cardiac events that significantly increases
,myocardial irritability, predisposing the patient to malignant ventricular
arrhythmias such as ventricular tachycardia and ventricular fibrillation.
Checking and correcting potassium levels is a priority intervention.
A patient with heart failure is receiving intravenous furosemide. Over
the last four hours, the patient's urine output has dropped
significantly, and serum laboratory results indicate worsening
azotemia. Which acid-base imbalance is this patient most at risk of
developing?
A. Respiratory alkalosis
B. Metabolic alkalosis
C. Respiratory acidosis
D. Metabolic acidosis
🟢 Correct answer: B. Metabolic alkalosis
🔴 Explanation: Aggressive diuresis with loop diuretics like furosemide
can lead to a contraction alkalosis alongside significant chloride and
potassium losses, resulting in metabolic alkalosis as the kidneys retain
bicarbonate to maintain electroneutrality.
A patient is admitted to the progressive care unit following a
percutaneous coronary intervention via the right femoral approach.
Two hours post-procedure, the nurse notes a expanding hematoma
at the insertion site and a weak, thready pedal pulse in the affected
extremity. What is the nurse's immediate priority action?
A. Document the findings and recheck in fifteen minutes
B. Apply direct manual pressure proximal to the puncture site and notify
the physician
C. Elevate the affected extremity to promote venous return
D. Encourage the patient to perform deep breathing exercises
🔴 Explanation: An expanding hematoma combined with diminished
distal perfusion indicates acute arterial compromise or active bleeding
from the access site. Immediate manual pressure proximal or directly
over the site controls hemorrhage, and urgent physician notification is
critical to prevent limb ischemia or shock.
A nurse is evaluating a patient with chronic obstructive pulmonary
disease who is experiencing acute respiratory distress. Arterial blood
gas results show pH 7.31, PaCO2 58 mmHg, HCO3 28 mEq/L, and
PaO2 55 mmHg. How should the nurse interpret these findings?
,A. Fully compensated metabolic alkalosis
B. Acute respiratory alkalosis with hypoxemia
C. Partially compensated respiratory acidosis with hypoxemia
D. Uncompensated metabolic acidosis with hypercapnia
🟢 Correct answer: C. Partially compensated respiratory acidosis with
hypoxemia
🔴 Explanation: A low pH combined with an elevated PaCO2 indicates
respiratory acidosis. The elevated bicarbonate level reflects renal
compensation attempting to buffer the acidotic state, while the low PaO2
confirms hypoxemia.
A patient with severe sepsis is receiving an infusion of
norepinephrine. The nurse assesses the peripheral intravenous site
in the forearm and notes cool, blanched skin with swelling and
absence of blood return. What is the immediate action the nurse
must take?
A. Apply warm compresses to the site to promote absorption
B. Stop the infusion immediately and disconnect the tubing
C. Flush the line with normal saline to clear the medication
D. Administer subcutaneous phentolamine into the surrounding tissue
🟢 Correct answer: B. Stop the infusion immediately and disconnect the
tubing
🔴 Explanation: Norepinephrine is a potent vasoconstrictor that can
cause severe tissue necrosis and sloughing if extravasated. The
immediate priority is to stop the infusion to prevent further drug entry into
the interstitial space before attempting to aspirate residual drug and
administering an antidote like phentolamine.
A progressive care nurse is caring for a patient admitted with
diabetic ketoacidosis. The patient's blood glucose is now 240 mg/dL,
and regular insulin infusion is running. Which additional intravenous
solution should the nurse anticipate adding to the current regimen to
prevent cerebral edema?
A. 0.9% Sodium Chloride with potassium chloride
B. 5% Dextrose in 0.45% Sodium Chloride with potassium chloride
C. Lactated Ringer's solution without additives
D. 3% Sodium Chloride with potassium chloride
🔴 Explanation: Once the blood glucose level drops to approximately 200
to 250 mg/dL in diabetic ketoacidosis, dextrose must be added to the
, intravenous fluids (typically 5% dextrose in half-normal saline) to prevent
rapid drops in serum osmolality, which can cause cerebral edema, while
allowing continued insulin administration to clear ketoacids.
A patient with a history of cirrhosis is admitted with altered mental
status and lethargy. The nurse notes a musty, sweet odor on the
patient's breath and observes flapping tremors of the hands when
extended. Which laboratory abnormality is primarily responsible for
these clinical manifestations?
A. Elevated serum ammonia
B. Decreased serum albumin
C. Elevated serum bilirubin
D. Decreased platelet count
🟢 Correct answer: A. Elevated serum ammonia
🔴 Explanation: Hepatic encephalopathy is caused by the accumulation
of neurotoxins, primarily ammonia, which the diseased liver can no longer
convert into urea. Asterixis (flapping tremors) and fetor hepaticus (musty
breath odor) are hallmark clinical signs.
A patient is admitted to the progressive care unit with a diagnosis of
acute pancreatitis. Which of the following assessment findings
warrants immediate notification of the provider?
A. Mild upper abdominal tenderness
B. Absent bowel sounds throughout all four quadrants
C. Development of rigid, board-like abdomen with severe pain
D. Low-grade fever of 38.0 degrees Celsius
🟢 Correct answer: C. Development of rigid, board-like abdomen with
severe pain
🔴 Explanation: A rigid, board-like abdomen indicates peritoneal irritation
and suggests severe complications such as pancreatic necrosis,
hemorrhage, or perforation, which represent surgical emergencies
requiring immediate intervention.
A patient is recovering from a thyroidectomy. Six hours post-
operatively, the patient reports numbness and tingling around the
lips and fingertips, and the nurse observes involuntary carpopedal
spasms when inflating a blood pressure cuff. What is the underlying
cause of these symptoms?
