ANCC Adult-Gerontology Clinical Nurse Specialist Certification Examination Practice Test
Adult-gerontology clinical nurse specialist practice applies advanced nursing judgment to the care of adults and older adults with acute and chronic conditions. The question bank samples medication safety, symptom evaluation, chronic disease management, patient education, and responses to changes in clinical status.
Exam overview
About the ANCC Adult-Gerontology Clinical Nurse Specialist Certification Exa… Exam
CNS work involves interpreting patient findings, identifying risks, and coordinating evidence-informed interventions with patients, families, and the care team. Scenarios in this practice bank include recognizing possible digoxin toxicity in the setting of hypokalemia, responding to a supratherapeutic INR, and assessing worsening heart failure symptoms. Other cases address medication timing and interactions, safe home oxygen use, contrast exposure in chronic kidney disease, diabetes treatment when hypoglycemia occurs, and suicide-risk assessment. These situations call for prioritizing immediate safety, distinguishing urgent findings from routine follow-up needs, and tailoring education to the patient’s condition and treatment. They also exercise clinical reasoning across pharmacology, assessment, prevention of complications, and communication with prescribers.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A 74-year-old with chronic obstructive pulmonary disease uses oxygen at home. Which instruction best supports safe oxygen use?
Show answer
Correct answer: AOxygen supports combustion, so it must be kept away from smoking, open flames, and other ignition sources. Cylinders should be stored securely according to supplier and device instructions. Oxygen flow should not be changed without an individualized clinical plan.
A 69-year-old who takes levothyroxine for hypothyroidism reports taking it with breakfast and a calcium supplement each morning. Which teaching is most appropriate?
Show answer
Correct answer: AFood and calcium can reduce levothyroxine absorption. Consistent administration on an empty stomach, with calcium separated by several hours, supports reliable absorption; the prescribed dose should not be changed without clinical guidance.
A 69-year-old reports persistent heartburn and difficulty swallowing solid food. Which response is most appropriate?
Show answer
Correct answer: ADysphagia accompanying reflux symptoms warrants evaluation rather than routine self-treatment alone. It may reflect a structural or other clinically significant condition, and assessment should not be delayed.
A 72-year-old taking digoxin for atrial fibrillation reports nausea and yellow-green halos around lights. The serum potassium is 3.0 mEq/L. What is the most appropriate immediate action?
Show answer
Correct answer: BNausea and visual color changes can indicate digoxin toxicity. Hypokalemia increases myocardial sensitivity to digoxin, raising the risk of dysrhythmias. The medication should be held while the patient receives prompt clinical evaluation, including assessment of rhythm, renal function, electrolytes, and digoxin level as indicated.
A 68-year-old taking warfarin for atrial fibrillation has an international normalized ratio (INR) of 5.2 and no bleeding. What is the best initial response by the CNS?
Show answer
Correct answer: AAn INR of 5.2 is above the usual therapeutic range for many indications and raises bleeding risk. Assess for bleeding and coordinate timely management according to the patient's indication and local protocol; dose decisions should be made by the responsible clinician.
A 74-year-old with a history of peptic ulcer disease is prescribed daily low-dose aspirin for secondary prevention after myocardial infarction. Which counseling point is most appropriate?
Show answer
Correct answer: AAspirin increases gastrointestinal bleeding risk, particularly in someone with prior ulcer disease. Melena or hematemesis may indicate significant bleeding and requires prompt evaluation; the patient should not independently alter prescribed therapy.
A 72-year-old with heart failure reports a 2.5-kg (5.5-lb) weight increase over four days and new ankle swelling. Which action is most appropriate for the CNS to recommend?
Show answer
Correct answer: ARapid weight gain and new edema can indicate worsening congestion in heart failure. Prompt assessment and use of the individualized action plan support timely evaluation and treatment. Patients should not independently stop or change prescribed medication.
How to use this practice test
Access is free. The session presents up to 20 random questions from the 50-question AGCNS-BC practice bank, then shows results. Use each case to explain the clinical cue that drives the decision, identify the safest next step, and note any medication or follow-up issue to revisit.
Preparation tips
- For medication scenarios, connect the symptom or laboratory value to the drug’s risks, such as hypokalemia increasing concern about digoxin toxicity or a high INR increasing bleeding risk.
- Practice distinguishing findings that need prompt escalation—such as new heart failure symptoms or suicidal thoughts—from concerns that call for planned education and monitoring.
- Review medication-administration counseling, including levothyroxine separation from calcium and aspirin-related bleeding precautions in a patient with prior peptic ulcer disease.
- For older adults with diabetes or kidney disease, consider treatment harm as well as disease control, including hypoglycemia with insulin and renal risk before contrast imaging.
- When answering each case, state the immediate safety priority, the assessment or action that follows, and the patient-specific teaching or team communication needed.
