Question 1: A progressive care nurse is assessing a patient recovering from an
acute myocardial infarction who suddenly develops ventricular tachycardia with a
pulse. Which intervention should the nurse prioritize? A. Administer intravenous
amiodarone B. Perform synchronized cardioversion C. Initiate chest compressions D.
Apply transcutaneous pacing pads CORRECT ANSWER: A. Administer intravenous
amiodarone Rationale: For stable ventricular tachycardia with a pulse, antiarrhythmic
therapy such as IV amiodarone is the first-line intervention per ACLS guidelines.
Synchronized cardioversion is indicated if the patient becomes hemodynamically
unstable. Chest compressions are for pulseless rhythms, and pacing is for symptomatic
bradycardia or heart block.
Question 2: A patient in the progressive care unit is receiving a continuous heparin
infusion for deep vein thrombosis. The nurse notes the activated partial
thromboplastin time (aPTT) is 110 seconds. What is the most appropriate nursing
action? A. Continue the infusion at the current rate B. Decrease the infusion rate per
protocol C. Administer protamine sulfate immediately D. Obtain a stat repeat aPTT
before adjusting CORRECT ANSWER: B. Decrease the infusion rate per protocol
Rationale: The therapeutic aPTT range for heparin is typically 1.5 to 2.5 times the control
(usually 60-80 seconds). An aPTT of 110 seconds indicates supratherapeutic
anticoagulation and increased bleeding risk. The nurse should pause or decrease the
infusion per institutional protocol and monitor closely. Protamine is reserved for major
bleeding or severe overdose.
Question 3: Which laboratory finding would most strongly indicate the onset of
acute kidney injury in a progressive care patient with sepsis? A. Serum creatinine
increase of 0.3 mg/dL within 48 hours B. Blood urea nitrogen decrease of 5 mg/dL C.
Serum sodium level of 132 mEq/L D. Potassium level of 4.1 mEq/L CORRECT ANSWER:
A. Serum creatinine increase of 0.3 mg/dL within 48 hours Rationale: The KDIGO
criteria define acute kidney injury as an increase in serum creatinine by ≥0.3 mg/dL
within 48 hours or ≥1.5 times baseline within 7 days. This early marker is critical for
timely intervention in septic patients. The other options do not specifically indicate AKI
onset.
Question 4: A patient with chronic obstructive pulmonary disease is admitted with
acute hypercapnic respiratory failure. Noninvasive positive pressure ventilation
(NIPPV) is initiated. Which assessment parameter requires the most vigilant
monitoring? A. Oxygen saturation via pulse oximetry B. Mental status and level of
consciousness C. Skin temperature over the extremities D. Urine output per hour
,CORRECT ANSWER: B. Mental status and level of consciousness Rationale: Altered
mental status is a key indicator of worsening hypercapnia or NIPPV failure. Deteriorating
consciousness may signal the need for endotracheal intubation. While SpO2 is
monitored, it does not reflect CO2 retention. Skin temperature and urine output are
important but less specific to acute ventilatory failure.
Question 5: Which medication should a progressive care nurse anticipate
administering first to a patient experiencing an acute severe asthma exacerbation
unresponsive to initial bronchodilators? A. Intravenous magnesium sulfate B. Oral
montelukast C. Inhaled ipratropium bromide D. Subcutaneous epinephrine CORRECT
ANSWER: A. Intravenous magnesium sulfate Rationale: IV magnesium sulfate is a
recommended adjunctive therapy for severe asthma exacerbations not responding to
initial beta-agonists and corticosteroids. It promotes bronchodilation by inhibiting
calcium influx in smooth muscle cells. Epinephrine is reserved for anaphylaxis or status
asthmaticus with impending respiratory arrest.
Question 6: A patient post-coronary artery bypass graft surgery develops new-
onset atrial fibrillation with a ventricular rate of 150 beats/min. The blood pressure
is 102/68 mm Hg and the patient is diaphoretic. What is the priority intervention? A.
Administer oral metoprolol B. Initiate synchronized electrical cardioversion C. Start an
intravenous heparin drip D. Apply vagal maneuvers CORRECT ANSWER: B. Initiate
synchronized electrical cardioversion Rationale: Atrial fibrillation with rapid
ventricular response causing hemodynamic instability (hypotension, diaphoresis, signs
of shock) requires immediate synchronized cardioversion. Medications are
contraindicated as first-line in unstable patients. Anticoagulation is important for stroke
prevention but not the immediate priority in acute instability.
Question 7: When caring for a patient with elevated intracranial pressure, which
nursing intervention is most appropriate to maintain cerebral perfusion? A. Elevate
the head of the bed to 45 degrees B. Cluster all nursing activities during the night C.
Maintain the head in a neutral, midline position D. Administer hypotonic intravenous
fluids CORRECT ANSWER: C. Maintain the head in a neutral, midline position
Rationale: Keeping the head midline promotes venous drainage from the brain and
reduces ICP. The HOB should be elevated 30-45 degrees, not strictly 45 if
contraindicated. Clustering activities can increase ICP spikes. Hypotonic fluids can
worsen cerebral edema; isotonic solutions are preferred.
Question 8: A progressive care patient with type 1 diabetes is experiencing diabetic
ketoacidosis. After initiating fluid resuscitation and insulin therapy, which
electrolyte requires the most aggressive monitoring and replacement? A. Sodium B.
Calcium C. Potassium D. Phosphorus CORRECT ANSWER: C. Potassium Rationale:
Insulin drives potassium intracellularly, often precipitating severe hypokalemia during
DKA treatment. Serum potassium must be monitored frequently and replaced
aggressively once levels fall below 5.3 mEq/L to prevent life-threatening dysrhythmias.
Other electrolytes are monitored but potassium shifts pose the most immediate threat.
,Question 9: Which clinical manifestation is most indicative of a pulmonary
embolism in a postoperative progressive care patient? A. Gradual onset of
productive cough B. Sudden onset of dyspnea and pleuritic chest pain C. Low-grade
fever and chills D. Wheezing bilaterally on auscultation CORRECT ANSWER: B. Sudden
onset of dyspnea and pleuritic chest pain Rationale: PE classically presents with
abrupt dyspnea, pleuritic chest pain, tachycardia, and hypoxemia. These signs reflect
acute ventilation-perfusion mismatch. Gradual cough, fever, or wheezing suggest
infection or bronchospasm rather than acute embolic event.
Question 10: A patient with acute pancreatitis is receiving aggressive fluid
resuscitation. Which assessment finding suggests fluid overload rather than
therapeutic response? A. Decreased heart rate from 110 to 88 bpm B. Increased urine
output to 45 mL/hr C. Crackles in bilateral lung bases D. Improved skin turgor CORRECT
ANSWER: C. Crackles in bilateral lung bases Rationale: Basilar crackles indicate
pulmonary congestion from fluid overload, a known risk during aggressive resuscitation
for pancreatitis. Decreased HR, improved urine output, and better skin turgor are signs
of effective volume restoration. Crackles require prompt intervention to prevent
respiratory compromise.
Question 11: Which intervention is most critical for preventing ventilator-
associated pneumonia in a mechanically ventilated progressive care patient? A.
Changing ventilator circuits every 48 hours B. Maintaining endotracheal tube cuff
pressure at 30 cm H2O C. Elevating the head of the bed to 30-45 degrees D. Performing
routine oral suctioning every 2 hours CORRECT ANSWER: C. Elevating the head of the
bed to 30-45 degrees Rationale: HOB elevation is a cornerstone VAP prevention bundle
that reduces aspiration of gastric secretions. Cuff pressure should be 20-30 cm H2O.
Routine circuit changes and excessive suctioning can actually increase VAP risk by
introducing pathogens or causing mucosal trauma.
Question 12: A patient with acute heart failure is prescribed entresto. Which
laboratory parameter must be closely monitored during the first 30 days of
therapy? A. Liver transaminases B. Serum potassium and renal function C. Complete
blood count with differential D. Thyroid stimulating hormone CORRECT ANSWER: B.
Serum potassium and renal function Rationale: Entresto (sacubitril/valsartan) carries
a black box warning for angioedema and risk of hypotension, hyperkalemia, and renal
impairment. Monitoring potassium and creatinine is essential, especially during
initiation and dose titration. Other labs are not primary monitoring requirements for this
medication.
Question 13: A progressive care nurse is caring for a patient with severe sepsis who
has a central venous oxygen saturation (ScvO2) of 60%. What does this finding
indicate? A. Adequate tissue oxygenation B. Increased oxygen delivery C. Inadequate
oxygen delivery relative to demand D. Hyperdynamic cardiac state CORRECT ANSWER:
C. Inadequate oxygen delivery relative to demand Rationale: Normal ScvO2 is 70-
80%. A value of 60% indicates increased oxygen extraction by tissues due to inadequate
, delivery, signaling ongoing tissue hypoxia despite resuscitation. This requires
intervention to optimize cardiac output, hemoglobin, or arterial oxygen saturation.
Question 14: Which diagnostic test is considered the gold standard for confirming
the presence of acute myocardial infarction in the progressive care setting? A. 12-
lead electrocardiogram B. Serum troponin I levels C. Echocardiography D. Coronary
angiography CORRECT ANSWER: B. Serum troponin I levels Rationale: Cardiac
troponins (I or T) are highly sensitive and specific biomarkers of myocardial necrosis and
are the diagnostic standard for MI per current guidelines. ECG shows ischemia but is
not definitive alone. Echo shows wall motion abnormalities but is secondary.
Angiography is therapeutic/diagnostic for coronary anatomy, not biomarker
confirmation.
Question 15: A patient with Guillain-Barré syndrome is admitted to the progressive
care unit. Which complication requires the highest priority monitoring? A.
Autonomic instability B. Decreased bowel motility C. Acute respiratory failure D.
Sensory neuropathy progression CORRECT ANSWER: C. Acute respiratory failure
Rationale: Ascending muscle weakness in GBS can rapidly involve the diaphragm and
intercostal muscles, leading to respiratory failure. Serial vital capacity and negative
inspiratory force measurements are essential. Autonomic instability and bowel
dysfunction are important but airway and breathing take priority.
Question 16: When administering intravenous vancomycin for a central line-
associated bloodstream infection, which nursing action prevents red man
syndrome? A. Dilute the medication in 250 mL of dextrose 5% B. Infuse the medication
over at least 60 minutes C. Administer diphenhydramine prior to infusion D. Use an
inline filter with a 0.22-micron pore size CORRECT ANSWER: B. Infuse the medication
over at least 60 minutes Rationale: Red man syndrome is a rate-related histamine
release reaction. Slowing the infusion to at least 10 mg/kg/hr or 1 gram over 60 minutes
prevents this reaction. Pre-medication with antihistamines is sometimes used but does
not replace proper infusion rate control. Dextrose solutions and filters do not prevent
this reaction.
Question 17: A progressive care patient with liver cirrhosis develops asterixis and
confusion. Which medication should the nurse anticipate administering? A.
Lactulose B. Furosemide C. Omeprazole D. Midazolam CORRECT ANSWER: A.
Lactulose Rationale: Asterixis and confusion indicate hepatic encephalopathy from
ammonia accumulation. Lactulose acidifies the colon, trapping ammonia as
ammonium and promoting excretion. Diuretics and PPIs are used for cirrhosis
complications but do not treat encephalopathy. Benzodiazepines are contraindicated
as they worsen mental status.
Question 18: Which hemodynamic parameter is most indicative of left ventricular
preload? A. Central venous pressure B. Pulmonary artery occlusion pressure C.
Systemic vascular resistance D. Cardiac output CORRECT ANSWER: B. Pulmonary
artery occlusion pressure Rationale: PAOP (wedge pressure) directly reflects left atrial
