1.
A patient becomes pale, diaphoretic, confused, and
hypotensive several minutes after receiving an injectable
medication. Which action should the Aerospace Medical
Service technician prioritize?
A. Document the reaction and reassess the patient in 30
minutes
B. Place the patient in a seated position and obtain a routine
history
C. Initiate emergency assessment and notify the appropriate
medical provider immediately
D. Administer the patient's next scheduled medication
Rationale: C is correct because the combination of hypotension,
altered mental status, pallor, and diaphoresis may indicate a
potentially life-threatening adverse reaction, including
anaphylaxis or another form of shock. Immediate assessment of
airway, breathing, circulation, and level of consciousness is
,more important than routine documentation or delayed
reassessment. The technician should work within established
scope of practice and immediately activate the appropriate
emergency response.
2.
Which finding most strongly suggests increased work of
breathing in an adult patient?
A. Respiratory rate of 16/min with relaxed posture
B. Use of accessory muscles with intercostal retractions
C. Symmetric chest expansion without distress
D. Clear speech in complete sentences
Rationale: B is correct because accessory-muscle use and
retractions indicate increased respiratory effort. A normal
respiratory rate alone does not exclude respiratory compromise.
A patient who is struggling to breathe may initially maintain a
relatively normal rate while demonstrating increased effort.
3.
During adult CPR without an advanced airway, which
compression rate is consistent with current AHA guidance?
,A. 60–80/min
B. 80–90/min
C. 100–120/min
D. 130–150/min
Rationale: C is correct. The 2025 AHA Adult Basic Life Support
guidance recommends a compression rate of 100–120/min for
adult cardiac arrest. Compression depth should be at least 2
inches (5 cm) while avoiding excessive depth greater than
approximately 2.4 inches (6 cm).
4.
A medication order reads 0.5 g. The available tablets contain
250 mg each. How many tablets should be administered?
A. 0.5 tablet
B. 1 tablet
C. 2 tablets
D. 4 tablets
Rationale: C is correct. First convert 0.5 g to milligrams: 0.5 g ×
1,000 mg/g = 500 mg. Dividing the ordered dose of 500 mg by
the available 250 mg per tablet gives 2 tablets.
5.
, Which action best demonstrates proper use of standard
precautions?
A. Wearing gloves only when a patient has a documented
infection
B. Using contact precautions for every patient
C. Performing a risk assessment and using appropriate PPE
when exposure to infectious material is anticipated
D. Using an N95 respirator for every patient encounter
Rationale: C is correct. Standard precautions apply to all patient
care and are based on the anticipated risk of exposure to blood,
body fluids, nonintact skin, mucous membranes, or other
potentially infectious material. PPE is selected according to the
anticipated exposure rather than simply according to the
patient's diagnosis.
6.
A patient's radial pulse is irregular. Which technique is most
appropriate for obtaining an accurate pulse rate?
A. Count for 15 seconds and multiply by four
B. Count for 20 seconds and multiply by three
C. Count for 30 seconds and multiply by two
D. Count for a full 60 seconds
