Formatted for efficient review with topic-specific question groupings
Updates for 2026:
- Revised to reflect 2026/2027 NYCHA maintenance worker job task analysis
- Incorporated latest organisational behaviour research and case studies
- Aligned with PADI Open Water Diver 2026 standards and revised dive tables
- Expanded rationales to include common student misconceptions and distractors
- Enhanced coverage of safety regulations and ethical considerations across all subjects
Abstract:
This document serves as a comprehensive study aid for three distinct examinations: the NYC NYCHA Maintenance
Worker Exam administered by DCAS, the ORGB 3201 Organisational Behaviour final exam within higher
education business curricula, and the PADI Open Water Diver final exam for recreational scuba certification. Each
exam domain is covered through carefully selected questions that mirror the format and difficulty of the actual
assessments. The NYCHA section focuses on practical maintenance knowledge including HVAC, plumbing,
electrical systems, and workplace safety. The organisational behaviour component delves into theoretical
frameworks such as Maslow's hierarchy, Herzberg's two-factor theory, and contemporary leadership models. The
PADI section addresses essential diving physics, equipment operation, dive planning, and emergency response. All
250 questions are accompanied by correct answers and detailed rationales that explain why each choice is correct
or incorrect, facilitating deeper learning. This resource has been updated to align with the 2026/2027 academic
year and the latest industry standards, ensuring relevance and accuracy. Whether preparing for civil service
advancement, a business degree requirement, or diving certification, this bundle offers a structured and verified
path to success.

,Q1. A maintenance worker is troubleshooting a three-zone hydronic heating system.
Zone 1 is not heating, while zones 2 and 3 operate normally. The circulator pump for
zone 1 is running, but the supply pipe remains cold. Which of the following is the
most likely cause?
A. Airlock in the zone 1 loop
B. Failed zone valve actuator
C. Boiler low-water cutoff tripped
D. Expansion tank bladder ruptured
Correct Answer: B. Failed zone valve actuator
Rationale: Since the pump runs but no heat, the zone valve is likely not opening,
preventing hot water flow. An airlock could cause no flow but pump running would
typically overcome it; low-water cutoff affects all zones; expansion tank issue affects
system pressure, not one zone.
Why Wrong:
A - An airlock could cause cold pipe, but the pump running suggests flow obstruction
is not likely to be airlocked.
C - A tripped low-water cutoff would disable the entire boiler, not just one zone.
D - A ruptured bladder in the expansion tank would cause pressure fluctuations across
all zones.

Q2. In an organization with a strong clan culture, a new CEO attempts to implement
a market culture by introducing competitive performance metrics and individual
incentives. According to the Competing Values Framework, which outcome is most
likely in the short term?
A. Increased innovation and flexibility
B. Employee resistance and decreased morale
C. Improved efficiency and market share
D. Enhanced collaboration and knowledge sharing
Correct Answer: B. Employee resistance and decreased morale
Rationale: Clan culture values collaboration and employee development; shifting to
market culture creates a value conflict, leading to resistance and lower morale. Innovation
is more typical of adhocracy; efficiency may improve later but not immediately;
collaboration is clan characteristic.
Why Wrong:
A - Market culture focuses on competition, not innovation.
C - Performance may improve after adaptation, but short-term effects are negative.
D - Enhanced collaboration is characteristic of clan culture, not market culture.

Q3. A diver completes a dive to 30 meters for 30 minutes with a single air cylinder.
After surfacing, 20 minutes later, he develops a dull pain in the left shoulder and
fatigue. Using the US Navy Diving Manual, what is the appropriate initial treatment?
A. Oxygen first aid and recompression on USN Treatment Table 6
B. In-water recompression
C. Aspirin and rest
D. Immediate evacuation to a hospital for CT scan
Correct Answer: A. Oxygen first aid and recompression on USN Treatment Table 6
Rationale: The symptoms indicate decompression sickness (DCS). Standard treatment is
oxygen and recompression. In-water recompression is not recommended; aspirin may
mask symptoms; CT scan is not first-line for DCS.
Why Wrong:
B - In-water recompression is not recommended due to risks of hypothermia, oxygen
issues, and lack of medical supervision.
C - Aspirin can mask symptoms and delay proper treatment; rest alone is insufficient
for DCS.
D - CT scan is not indicated as initial management; immediate recompression is
required.

Q4. A manager notices that an employee has high expectancy and high
instrumentality but low valence for a new bonus system. According to Vroom's
Expectancy Theory, which intervention would most effectively increase motivation?
A. Increase the clarity of the performance-reward link
B. Provide training to improve the employee's skills
C. Redesign the bonus system to reward outcomes the employee values
D. Reduce the difficulty of performance goals
Correct Answer: C. Redesign the bonus system to reward outcomes the employee
values
Rationale: Valence (value of reward) is low; changing rewards to match employee
preferences directly addresses the motivational deficit. Clarity (instrumentality) and
training (expectancy) are already high; reducing goal difficulty may alter expectancy but
not the core issue.
Why Wrong:
A - Instrumentality is already high, so increasing clarity would have little effect.
B - Expectancy is high, so training is not needed.
