✍️ Sample AON Questions & Answers
1. A delivery truck completes 8 routes per day, each covering 45 miles. How many miles does it cover in a 5-day workweek?
8 × 45 × 5 = 1,800 miles per week.
2. How should relationships be formed during the interview process?
During the interview process, especially in healthcare, relationships should be formed in a personal and empathetic manner. This involves building rapport, showing genuine interest, and creating a comfortable environment for the patient to share information. A personal approach fosters trust and facilitates open communication, which is crucial for a comprehensive assessment.
3. Which portion of the stethoscope is intended to transmit the higher pitch of aberrant sounds while auscultating for lung sounds?
The diaphragm of a stethoscope is specifically designed to transmit higher-pitched sounds. Its taut, flat membrane vibrates more effectively with high-frequency sound waves, making it ideal for auscultating lung sounds like crackles and wheezes, as well as certain heart sounds. This design helps filter out lower frequencies, allowing for clearer detection of aberrant, high-pitched sounds.
4. Which number does NOT belong in the set: 4, 8, 12, 17, 20, 24?
All other numbers are multiples of 4, but 17 is not divisible by 4.
5. A factory produces 1,200 units per day. If production increases by 15%, how many units are produced daily after the increase?
1,200 × 1.15 = 1,380 units per day.
6. You are given an urgent task but realize you lack the knowledge to complete it. What should you do?
Acknowledging a knowledge gap and seeking support promptly leads to better outcomes than guessing or delaying.
