ATI MEDICAL-SURGICAL NURSING COMPREHENSIVE EXAMINATION: A COMPLETE 200-QUESTION PRACTICE TEST BANK COVERING CARDIOVASCULAR, RESPIRATORY, NEUROLOGICAL, GASTROINTESTINAL, ENDOCRINE, RENAL, MUSCULOSKELETAL, AND MULTISYSTEM DISORDERS WITH DETAILED RATIONALES, PRIORITIZATION STRATEGIES, CLINICAL JUDGMENT SCENARIOS, PHARMACOLOGY INTEGRATION, AND NCLEX-STYLE QUESTIONS FOR ADULT HEALTH NURSING CERTIFICATION PREPARATION Question 1: The nurse is caring for a client with acute pancreatitis. Which assessment finding indicates a potential complication that requires immediate intervention? A. Epigastric pain radiating to the back B. Serum amylase level of 350 U/L C. Cullen's sign present on abdominal assessment D. Nausea and vomiting CORRECT ANSWER: C. Cullen's sign present on abdominal assessment Rationale: Cullen's sign (periumbilical ecchymosis) indicates retroperitoneal bleeding, a severe complication of acute pancreatitis associated with hemorrhagic pancreatitis. This finding requires immediate intervention. Epigastric pain radiating to the back is a classic symptom of pancreatitis, elevated amylase is expected, and nausea/vomiting are common manifestations. ________________________________________ Question 2: A client with heart failure is prescribed furosemide. Which laboratory value should the nurse monitor most closely? A. Serum sodium B. Serum potassium C. Serum calcium D. Serum magnesium CORRECT ANSWER: B. Serum potassium Rationale: Furosemide is a loop diuretic that causes significant potassium wasting. Hypokalemia is a serious adverse effect that can precipitate cardiac arrhythmias, especially in clients taking digoxin. Monitoring potassium levels is essential for safety. ________________________________________ Question 3: The nurse is assessing a client with suspected pulmonary embolism. Which finding is most consistent with this diagnosis? A. Bradycardia and hypotension B. Sudden onset of pleuritic chest pain and dyspnea C. Productive cough with frothy sputum D. Wheezing on auscultation CORRECT ANSWER: B. Sudden onset of pleuritic chest pain and dyspnea Rationale: Pulmonary embolism typically presents with the sudden onset of pleuritic chest pain, dyspnea, and tachypnea. Tachycardia (not bradycardia) is expected. Frothy sputum suggests pulmonary edema, and wheezing indicates bronchospasm. ________________________________________ Question 4: A client with chronic kidney disease is scheduled for hemodialysis. Which medication should the nurse withhold prior to the procedure? A. Calcium supplement B. ACE inhibitor C. Iron supplement D. Phosphate binder CORRECT ANSWER: B. ACE inhibitor Rationale: ACE inhibitors should be withheld prior to hemodialysis because they can cause intradialytic hypotension. The other medications are typically administered with meals or as prescribed and do not pose the same risk during dialysis. ________________________________________ Question 5: The nurse is providing discharge teaching to a client with a new permanent pacemaker. Which instruction is most important to include? A. "You may resume driving immediately" B. "Avoid microwave ovens" C. "Keep your cell phone at least 6 inches from the pacemaker site" D. "You will need to avoid all physical activity" CORRECT ANSWER: C. "Keep your cell phone at least 6 inches from the pacemaker site" Rationale: Clients with pacemakers should keep cell phones at least 6 inches away from the pacemaker generator to prevent electromagnetic interference. Driving restrictions are typically 1-2 weeks, microwave ovens are safe (if functioning properly), and physical activity should be gradually resumed. ________________________________________ Question 6: A client with asthma is prescribed albuterol. Which assessment finding indicates the medication is effective? A. Decreased respiratory rate from 28 to 16 breaths per minute B. Increased wheezing on auscultation C. Decreased oxygen saturation D. Increased heart rate from 80 to 110 beats per minute CORRECT ANSWER: A. Decreased respiratory rate from 28 to 16 breaths per minute Rationale: Albuterol is a bronchodilator that opens airways, improving gas exchange and reducing work of breathing. A decreased respiratory rate indicates effectiveness. Wheezing should decrease, oxygen saturation should improve, and tachycardia is a side effect, not an indicator of effectiveness. ________________________________________ Question 7: The nurse is assessing a client with diabetes mellitus who reports numbness and tingling in both feet. This finding is most indicative of which complication? A. Peripheral neuropathy B. Peripheral vascular disease C. Diabetic retinopathy D. Nephropathy CORRECT ANSWER: A. Peripheral neuropathy Rationale: Diabetic peripheral neuropathy manifests as numbness, tingling, and burning pain in the extremities, typically beginning in the feet. This results from chronic hyperglycemia damaging peripheral nerves. PVD presents with diminished pulses, retinopathy affects vision, and nephropathy affects kidney function. ________________________________________ Question 8: A client is receiving a continuous enteral tube feeding. Which intervention is most important to prevent aspiration? A. Flush the tube with 30 mL of water every 4 hours B. Elevate the head of the bed to 30-45 degrees C. Check gastric residual volumes every 8 hours D. Change the feeding bag every 24 hours CORRECT ANSWER: B. Elevate the head of the bed to 30-45 degrees Rationale: Elevating the head of the bed to 30-45 degrees is the most effective intervention to prevent aspiration in clients receiving enteral feedings. While other interventions are important for safety, head elevation directly prevents reflux and aspiration.
