60 reports
90 reports
75 reports
66 reports (Correct answer)

Correct answer: 66 reports

30 days ÷ 7 × 5 ≈ 21.4 workdays ≈ 22 days × 3 = 66 reports.

Question 2: A bulletin reads: 'Officers responding to domestic disturbance calls should always have backup before entering the premises.' The word 'always' indicates this rule is:

A suggestion
Mandatory with no exceptions (Correct answer)
Situational
Optional

Correct answer: Mandatory with no exceptions

The word 'always' indicates the rule is mandatory with no exceptions.

Question 3: An evidence locker contains 72 items. If 1/4 of the items are released following case closures, how many items remain?

36 items
48 items
18 items
54 items (Correct answer)

Correct answer: 54 items

72 × 1/4 = 18 released; 72 − 18 = 54 items remain.

Question 4: Which sentence is written in active voice?

An arrest was made.
The suspect had been arrested.
The officer arrested the suspect. (Correct answer)
The suspect was arrested by the officer.

Correct answer: The officer arrested the suspect.

Active voice places the subject (officer) performing the action (arrested) directly.

Question 5: A first responder arrives at a scene where a victim has a suspected spinal injury. What is the most appropriate method to open the airway?

Recovery position
Head-tilt chin-lift
Finger sweep
Jaw thrust maneuver (Correct answer)

Correct answer: Jaw thrust maneuver

The jaw thrust maneuver opens the airway without moving the cervical spine, making it the safest choice for suspected spinal injury patients.

Question 6: When performing the Heimlich maneuver on a choking adult, where should your hands be placed?

Just above the navel (Correct answer)
On the chest
On the throat
On the back

Correct answer: Just above the navel

When performing the Heimlich maneuver (abdominal thrusts) on a choking adult, the rescuer should stand behind the person and wrap their arms around the waist. The critical placement for the hands is just above the navel (belly button), with one hand made into a fist and grasped by the other hand. This precise positioning allows for effective upward thrusts to dislodge the obstruction from the airway.

Question 7: If a car travels 270 miles in 4.5 hours, what is its average speed?

60 mph (Correct answer)
70 mph
65 mph
55 mph

Correct answer: 60 mph

Speed = distance ÷ time = 270 ÷ 4.5 = 60 mph.

Question 8: A law enforcement agency collected data showing that 60% of traffic accidents occur at intersections, 25% on highways, and the remainder on residential streets. If 840 accidents occurred last year, how many happened on residential streets?

210
504
84
126 (Correct answer)

Correct answer: 126

Residential streets account for 100% - 60% - 25% = 15% of accidents. 15% of 840 = 840 × 0.15 = 126 accidents.

Question 9: A directive states: 'Supervisors must review all use-of-force reports within 48 hours.' A report is submitted Friday at 9 AM. When is the review deadline?

Saturday 9 AM

Handle the call yourself but be lenient because of the friendship
Ask your friend to leave the scene before backup arrives
Disclose the relationship to your supervisor and request reassignment if possible (Correct answer)

Correct answer: Disclose the relationship to your supervisor and request reassignment if possible

Disclosing potential conflicts of interest to a supervisor is the ethical standard; it protects the officer, the investigation, and the integrity of the process.

Question 11: A suspect fled on foot at 8 mph. An officer began pursuit 5 minutes later at 12 mph. How many minutes will it take the officer to catch the suspect?

8 minutes
12 minutes
15 minutes
10 minutes (Correct answer)

Correct answer: 10 minutes

The suspect's 5-minute head start at 8 mph = 0.667 miles; closing speed is 4 mph; 0.667 ÷ 4 = ~10 minutes.

Question 12: A store sells items at a 25% discount. If the original price is $80, what is the sale price?

$65
$55
$60 (Correct answer)
$70

Correct answer: $60

Discount = 25% of $80 = $20, so the sale price = $80 − $20 = $60.

Question 13: You observe a colleague falsifying a police report. What is the MOST appropriate action?

Report the misconduct to a supervisor or internal affairs immediately (Correct answer)
Wait to see if the colleague corrects the report on their own
Ignore it since it does not involve you directly
Confront the colleague privately and ask them to stop

Correct answer: Report the misconduct to a supervisor or internal affairs immediately

Report falsification is a serious offense that undermines the justice system; officers have an affirmative duty to report known misconduct to supervisors or internal affairs.

Question 14: While on foot patrol you notice a juvenile who appears to be under the influence of alcohol. The juvenile refuses to identify themselves. What is your BEST course of action?

Detain the juvenile for their safety, attempt to identify them, and notify a supervisor (Correct answer)
Let the juvenile go since minors cannot be detained
Arrest the juvenile immediately for underage drinking
Call the juvenile's school to have them identified

Correct answer: Detain the juvenile for their safety, attempt to identify them, and notify a supervisor

Leave the error since changing reports looks suspicious
Ask a colleague to submit the correction under their name
Submit a supplemental report correcting the error and note the change (Correct answer)

Correct answer: Submit a supplemental report correcting the error and note the change

Supplemental reports are the proper procedure for correcting documented errors; altering original reports without documentation is considered falsification.

Question 21: In a hydraulic system, if the force applied on the smaller piston is increased, what happens to the pressure in the system?

It fluctuates
It decreases
It increases (Correct answer)
It remains the same

Correct answer: It increases

In a hydraulic system, pressure is transmitted equally throughout an enclosed fluid, as described by Pascal's principle. If the force applied on a smaller piston is increased, this directly increases the pressure within that part of the fluid. Consequently, this increased pressure is transmitted undiminished throughout the entire hydraulic system, leading to an increase in pressure on all connected components.

Question 22: A suspect is described as having a distinctive tattoo on the left forearm. When making an identification, which step is MOST important?

Check for the tattoo only if the suspect removes clothing voluntarily
Confirm the tattoo's exact location and description (Correct answer)

3:1
9:1
12:1
4:1 (Correct answer)
