, Question 1
A casualty with a suspected tension pneumothorax and ongoing respiratory
distress requires needle decompression. Which anatomical site is now preferred
in adults per current Tactical Combat Casualty Care (TCCC) guidelines to
reduce failure rates?
A. Second intercostal space, midclavicular line
B. Fifth intercostal space, anterior axillary line
C. Fourth intercostal space, midaxillary line
D. Second intercostal space, anterior axillary line
Correct Answer: B - Fifth intercostal space, anterior axillary line
RATIONALE
Current TCCC and JTS guidelines recommend the fifth intercostal
space at the anterior axillary line to improve success rates and reduce
complications compared to the traditional second intercostal space
midclavicular approach. The other options are either outdated or less
effective due to chest wall thickness and anatomical variability.
Question 2
A hospital corpsman is preparing to administer a controlled substance for pain
management. Which of the following is the most critical legal requirement
under the Controlled Substances Act and Navy regulations?
A. Documenting the administration within 24 hours
B. Verifying the medication with a second licensed provider
C. Maintaining a perpetual inventory log and securing the substance in a
locked container
D. Obtaining verbal consent from the patient before administration
Correct Answer: C - Maintaining a perpetual inventory log and
securing the substance in a locked container
Page 2
, RATIONALE
Controlled substances require strict accountability, including perpetual
inventory logs and secure storage, per federal and Navy regulations.
While documentation and verification are important, the fundamental
legal requirement is maintaining an accurate inventory and secure
storage to prevent diversion.
Question 3
During a field exercise, multiple personnel present with watery diarrhea,
abdominal cramps, and low-grade fever after consuming food from a common
source. Which epidemiological measure best determines the source of the
outbreak?
A. Calculating the attack rate among those who ate specific food items
B. Performing stool cultures on all affected personnel
C. Isolating all symptomatic individuals immediately
D. Administering broad-spectrum antibiotics prophylactically
Correct Answer: A - Calculating the attack rate among those who
ate specific food items
RATIONALE
The attack rate (number of new cases among exposed divided by total
exposed) is the key epidemiological tool to identify the likely food
source in a common-source outbreak. Stool cultures identify the
pathogen but not the source; isolation and prophylaxis are control
measures, not source identification.
Question 4
Which of the following best describes the primary role of a Hospital Corpsman
Second Class (HM2) in the mentorship of junior corpsmen?
A. Conducting formal performance evaluations only
B. Providing technical guidance, professional development, and role
modeling
Page 3
, C. Assigning daily work schedules and leave requests
D. Administering disciplinary action for minor infractions
Correct Answer: B - Providing technical guidance, professional
development, and role modeling
RATIONALE
HM2s are expected to mentor junior personnel through technical
instruction, professional development, and leading by example,
fostering a culture of excellence and readiness. Formal evaluations,
scheduling, and discipline are typically the responsibility of senior
leadership (HM1/Chief), though HM2s may provide input.
Question 5
A patient with a known penicillin allergy requires antibiotic prophylaxis for a
dental procedure. Which alternative is most appropriate according to current
AHA guidelines?
A. Cephalexin
B. Azithromycin
C. Amoxicillin
D. Imipenem
Correct Answer: B - Azithromycin
RATIONALE
For patients with penicillin allergy, azithromycin (or clindamycin) is
recommended for dental prophylaxis per AHA guidelines. Cephalexin
may have cross-reactivity, amoxicillin is a penicillin, and imipenem is
reserved for severe infections and also has cross-reactivity risk.
Question 6
In a mass casualty scenario, a corpsman must triage patients using the Sort,
Assess, Lifesaving Interventions, Treatment/Transport (SALT) method. Which
patient should be prioritized for immediate lifesaving intervention?
