INTRODUCTION
This comprehensive ATI Med-Surg practice assessment emphasizes advanced
clinical judgment across major adult medical-surgical systems. Questions integrate
pathophysiology, assessment findings, pharmacologic management, prioritization,
delegation, safety, complications, laboratory interpretation, and evidence-based
nursing interventions. The difficulty is intentionally elevated to challenge learners
preparing for comprehensive predictor-style assessments and advanced
professional nursing examinations. Expect realistic clinical scenarios requiring
interpretation rather than simple memorization. Particular emphasis is placed on
recognizing deterioration, identifying the highest-priority intervention, evaluating
treatment effectiveness, anticipating complications, and distinguishing expected
findings from manifestations requiring immediate action.
QUESTION 1
A client with acute decompensated heart failure is receiving IV furosemide. Two
hours after administration, the client reports generalized weakness and palpitations.
The cardiac monitor shows frequent premature ventricular contractions. Which
laboratory result should the nurse anticipate?
,A. Sodium 140 mEq/L
B. Potassium 2.9 mEq/L
C. Calcium 9.4 mg/dL
D. Magnesium 2.1 mg/dL
🔴 Correct Answer: B. Potassium 2.9 mEq/L.
🔵 Explanation: Furosemide is a loop diuretic that increases urinary potassium
excretion. Hypokalemia can cause muscle weakness, palpitations, and ventricular
dysrhythmias, including premature ventricular contractions. A potassium of 2.9 mEq/L
is clinically significant and requires prompt intervention.
QUESTION 2
A client with septic shock has received an appropriate crystalloid bolus. The blood
pressure remains 78/44 mm Hg, urine output is 10 mL/hr, and serum lactate is 5.1
mmol/L. Which intervention should the nurse anticipate next?
A. Administer IV furosemide
B. Initiate a vasopressor infusion
C. Restrict further IV fluids
D. Administer oral antihypertensive medication
🔴 Correct Answer: B. Initiate a vasopressor infusion.
🔵 Explanation: Persistent hypotension and evidence of tissue hypoperfusion despite
adequate fluid resuscitation indicate septic shock requiring vasopressor support.
Norepinephrine is commonly used as the first-line vasopressor to restore adequate
mean arterial pressure and organ perfusion.
QUESTION 3
A client with chronic obstructive pulmonary disease is receiving oxygen at 2 L/min
by nasal cannula. The client becomes increasingly somnolent. Arterial blood gas
results are pH 7.28, PaCO₂ 68 mm Hg, and HCO₃⁻ 31 mEq/L. Which interpretation is
most appropriate?
A. Uncompensated metabolic acidosis
B. Fully compensated respiratory alkalosis
C. Acute-on-chronic respiratory acidosis
D. Metabolic alkalosis with respiratory compensation
,🔴 Correct Answer: C. Acute-on-chronic respiratory acidosis.
🔵 Explanation: The elevated PaCO₂ indicates respiratory acidosis. The elevated
bicarbonate demonstrates renal compensation consistent with chronic CO₂ retention,
while the acidemic pH indicates an acute worsening. Increasing somnolence is
concerning for hypercapnic encephalopathy.
QUESTION 4
A client with diabetic ketoacidosis has received IV fluids and an insulin infusion.
Current laboratory results include glucose 248 mg/dL, potassium 3.1 mEq/L, and
bicarbonate 15 mEq/L. Which action is the priority?
A. Increase the insulin infusion rate
B. Administer potassium replacement as prescribed
C. Administer IV sodium bicarbonate immediately
D. Discontinue fluid replacement
🔴 Correct Answer: B. Administer potassium replacement as prescribed.
🔵 Explanation: Insulin drives potassium into cells and can produce life-threatening
hypokalemia. When potassium is significantly reduced, potassium replacement takes
priority before continued aggressive insulin therapy. The client still has metabolic
acidosis, but correcting the dangerous potassium deficit is essential.
QUESTION 5
A client with acute ischemic stroke develops sudden difficulty swallowing during a
bedside assessment. Which action should the nurse take first?
A. Provide thickened liquids
B. Place food on the unaffected side of the mouth
C. Keep the client NPO pending a formal swallowing evaluation
D. Encourage the client to cough before swallowing
🔴 Correct Answer: C. Keep the client NPO pending a formal swallowing
evaluation.
🔵 Explanation: Dysphagia after stroke creates a substantial aspiration risk. Oral
intake should be withheld until swallowing safety has been formally evaluated.
Providing food or liquids before evaluation may result in aspiration pneumonia or
airway compromise.
, QUESTION 6
A client receiving heparin for a pulmonary embolism has a platelet count that
decreases from 230,000/mm³ to 92,000/mm³ over several days. Which action is
most appropriate?
A. Continue heparin because the platelet count remains above 50,000/mm³
B. Administer an additional heparin bolus
C. Suspect heparin-induced thrombocytopenia and notify the provider
D. Administer aspirin and continue the infusion
🔴 Correct Answer: C. Suspect heparin-induced thrombocytopenia and notify the
provider.
🔵 Explanation: A platelet decline of more than 50% after heparin exposure is highly
concerning for heparin-induced thrombocytopenia, particularly when thrombosis is
present. Heparin should be stopped and an alternative anticoagulant anticipated
according to the treatment plan.
QUESTION 7
A client with chronic kidney disease has potassium of 6.8 mEq/L and ECG changes
showing peaked T waves. Which prescribed medication should the nurse administer
first?
A. Sodium polystyrene sulfonate
B. IV calcium gluconate
C. Oral sodium bicarbonate
D. IV furosemide
🔴 Correct Answer: B. IV calcium gluconate.
🔵 Explanation: Severe hyperkalemia with ECG changes is an immediate cardiac
emergency. IV calcium stabilizes the myocardial membrane and reduces the risk of
fatal dysrhythmias. Calcium does not remove potassium, so additional therapies are
subsequently required to shift or eliminate potassium.
QUESTION 8
A client with SIADH has a serum sodium of 118 mEq/L and develops confusion and
a seizure. Which intervention should the nurse anticipate?
