COMPLETE STUDYGUIDE 2026/2027
1. During a mass casualty triage exercise aboard a deployed amphibious assault ship, a
Hospital Corpsman assesses a patient with severe facial burns, inspiratory stridor, and a
respiratory rate of 8 breaths per minute. According to tactical combat casualty care and
naval doctrine, what is the most immediate priority?
A. Administering high-flow supplemental oxygen via non-rebreather mask
B. Performing an immediate surgical cricothyroidotomy
C. Inserting a nasopharyngeal airway and monitoring oxygen saturation
D. Establishing intravenous access for fluid resuscitation
Rationale : Inhalation injuries involving severe facial burns and impending airway
obstruction indicated by inspiratory stridor and bradypnea require definitive airway control. A
surgical cricothyroidotomy is the primary intervention when upper airway compromise is
present and standard endotracheal intubation is unfeasible or fails.
2. A 24-year-old active duty sailor presents to sick call reporting progressive, painful
swelling in the right pre-auricular region that worsens significantly during meals. Physical
exam reveals tenderness over the parotid gland duct orifice with purulent discharge upon
milking the duct. Which organism is the most common causative agent of this acute
condition?
A. Streptococcus pyogenes
B. Staphylococcus aureus
C. Pseudomonas aeruginosa
D. Escherichia coli
Rationale : Acute bacterial parotitis is most commonly caused by Staphylococcus aureus,
particularly in dehydrated or debilitated patients. It presents with painful swelling exacerbated
by salivation and purulent ductal discharge.
3. A Second Class Petty Officer is counseling a junior corpsman regarding administrative
requirements for medical record documentation. Which instruction governs the
Department of the Navy policy for the management and maintenance of health records?
A. BUMEDINST 6230.15 series
B. NAVMED P-117
C. SECNAVINST 5210.11 series
D. BUMEDINST 6150.32 series
,Rationale : BUMEDINST 6150.32 series provides comprehensive guidelines and regulations
concerning the administration, management, and maintenance of Department of the Navy
health records.
4. An HM3 is preparing to administer penicillin G benzathine to a recruit diagnosed with
primary syphilis. The order calls for 2.4 million units intramuscularly. The medication vial
is labeled 1,200,000 units/2 mL. How many total milliliters must the corpsman administer?
A. 2.0 mL
B. 3.0 mL
C. 4.0 mL
D. 5.0 mL
Rationale : Using the formula (Desired / Stock) x Volume: (2,400,000 units / 1,200,000 units)
x 2 mL = 2 x 2 = 4.0 mL total volume.
5. A senior medical department representative is reviewing the ship’s potable water
surveillance program. According to Navy preventive medicine standards, what is the
mandatory minimum free available chlorine (FAC) residual required at routine
distribution taps throughout the vessel?
A. 0.2 ppm
B. 0.5 ppm
C. 1.0 ppm
D. 2.0 ppm
Rationale : Navy technical manuals for water safety require a minimum free available
chlorine residual of 0.2 ppm at all routine distribution points to ensure ongoing
microbiological safety.
6. A Marine infantryman returning from a field exercise in a temperate wooded
environment presents with a localized, expanding annular erythematous rash with central
clearing, accompanied by fatigue and arthralgias. The corpsman recognizes this classic
presentation as early localized manifestations of which vector-borne disease?
A. Rocky Mountain spotted fever
B. Lyme disease
C. Ehrlichiosis
D. Leptospirosis
Rationale : Erythema migrans, the expanding bull's-eye rash associated with early localized
Lyme disease (Borrelia burgdorferi), typically appears alongside flu-like symptoms following a
tick bite.
,7. When conducting routine maintenance on a standard field medical refrigerator used for
vaccine storage, the HM5 supervisor notes that perishable biologicals must be maintained
within what specific temperature range?
A. 2°C to 8°C (36°F to 46°F)
B. 0°C to 4°C (32°F to 39°F)
C. -15°C to -20°C (5°F to -4°F)
D. 8°C to 15°C (46°F to 59°F)
Rationale : Refrigerated vaccines must be stored strictly between 2°C and 8°C (36°F to 46°F)
to maintain potency without freezing, which can destroy the vaccine structure.
8. During a routine physical readiness assessment screening, a 32-year-old sailor has a
resting blood pressure reading of 142/92 mmHg confirmed on a separate occasion.
According to current clinical guidelines, this reading classifies the patient into which
category?
A. Elevated blood pressure
B. Stage 1 hypertension
C. Stage 2 hypertension
D. Hypertensive crisis
Rationale : Stage 2 hypertension is defined by a systolic blood pressure of 140 mmHg or
higher or a diastolic blood pressure of 90 mmHg or higher based on confirmed averaged
readings.
9. An HM1 is supervising the medical department's hazardous material management
program. Which specific instruction or manual establishes Department of the Navy policy
for hazard communication and safety data sheet (SDS) maintenance?
A. OPNAVINST 5100.23 series
B. NAVMED P-5010
C. BUMEDINST 6220.12 series
D. OPNAVINST 3500.39 series
Rationale : OPNAVINST 5100.23 series (Navy Safety and Occupational Health Program
Manual) dictates hazard communication standards, safety data sheet retention, and workplace
safety protocols.
10. A sailor assigned to engineering duty reports with severe pruritus, scaling, and
maceration between the fourth and fifth toe webs. Direct potassium hydroxide (KOH) wet
mount preparation reveals branching hyphae. What is the most appropriate initial
treatment regimen?
A. Oral fluconazole
B. Topical terbinafine cream
, C. Intravenous vancomycin
D. Topical hydrocortisone 2.5% ointment
Rationale : Tinea pedis (athlete's foot) is a dermatophyte infection effectively treated with
topical antifungal agents such as terbinafine or clotrimazole. Topical steroids worsen fungal
proliferation.
11. A Field Medical Service Technician is evaluating a casualty with suspected tension
pneumothorax. Which clinical sign is least likely to be present in the early stages of tension
pneumothorax?
A. Tracheal deviation toward the affected side
B. Absent breath sounds on the affected hemithorax
C. Hemodynamic instability with hypotension
D. Hyperresonance to percussion on the injured side
Rationale : Tracheal deviation is a classic, albeit relatively late, clinical finding in tension
pneumothorax. It occurs as high intrapleural pressure shifts mediastinal structures away from
(not toward) the affected side.
12. When organizing the medical department’s quality assurance program, the hospital
corpsman must understand that clinical peer reviews must be protected under which
authority to encourage candid professional evaluations?
A. Freedom of Information Act
B. Privacy Act of 1974
C. 10 U.S.C. Section 1102
D. Health Insurance Portability and Accountability Act
Rationale : 10 U.S.C. 1102 protects medical quality assurance documents and clinical peer
reviews from mandatory disclosure, fostering open peer review and risk reduction.
13. A 20-year-old sailor presents with acute onset of severe right lower quadrant abdominal
pain, low-grade fever, and localized rebound tenderness at McBurney's point. Which
specialized physical exam sign involves eliciting pain in the right lower quadrant during
deep palpation of the left lower quadrant?
A. Rovsing's sign
B. Psoas sign
C. Obturator sign
D. Murphy's sign
Rationale : Rovsing's sign is positive when pressure applied to the left lower quadrant elicits
referred pain in the right lower quadrant, strongly suggesting acute appendicitis.
