Questions with Correct Answers & Detailed
Rationales | Verified & Reliable
1. A patient with suspected hypovolemic shock has cool,
clammy skin, tachycardia, and delayed capillary refill. Which
intervention should receive the highest priority while definitive
treatment is arranged?
A. Encourage oral fluids
B. Place the patient in a hot shower
C. Administer oxygen as indicated and support circulation
D. Have the patient ambulate to improve circulation
Correct answer: C. Administer oxygen as indicated and
support circulation
Rationale: Hypovolemic shock results from inadequate
circulating volume and impaired tissue perfusion. Initial
management focuses on airway and breathing support, oxygen
when clinically indicated, rapid recognition of the cause, and
measures that support circulation while definitive fluid or blood-
product therapy is obtained. Oral fluids and ambulation are
inappropriate in a potentially unstable patient.
,2. During a primary assessment, a patient is found
unresponsive but is breathing normally and has a pulse. Which
action is most appropriate after confirming the absence of an
immediate airway obstruction?
A. Begin chest compressions
B. Place the patient in an appropriate recovery position and
monitor
C. Give the patient oral glucose
D. Have the patient stand and walk
Correct answer: B. Place the patient in an appropriate
recovery position and monitor
Rationale: An unresponsive patient who is breathing normally
and has a pulse does not require CPR solely because of the
altered level of consciousness. Maintaining airway patency,
protecting the patient from aspiration or injury, and
continuously reassessing breathing and circulation are
priorities. Oral substances should not be given to an
unresponsive patient.
3. Which finding is most consistent with an acute arterial
occlusion of an extremity?
,A. Warm skin with bilateral edema
B. Gradual hyperpigmentation
C. Sudden pain, pallor, pulselessness, and paresthesia
D. Chronic itching relieved by elevation
Correct answer: C. Sudden pain, pallor, pulselessness, and
paresthesia
Rationale: Acute arterial insufficiency classically produces the “6
Ps”: pain, pallor, pulselessness, paresthesia, paralysis, and
poikilothermia. The sudden loss of arterial perfusion makes this
a time-sensitive emergency requiring immediate evaluation and
intervention.
4. A patient receiving oxygen through a nasal cannula reports
increasing shortness of breath. Which assessment should the
medical technician perform first?
A. Determine the patient's favorite sleeping position
B. Reassess airway, breathing, respiratory rate, effort, and
oxygenation
C. Ask when the patient last ate
D. Obtain a complete family history
Correct answer: B. Reassess airway, breathing, respiratory
rate, effort, and oxygenation
, Rationale: Worsening dyspnea requires immediate
reassessment of the ABCs. The technician should determine
whether airway obstruction, inadequate ventilation, worsening
oxygenation, or increased respiratory effort is present. Less
urgent historical information can be obtained after immediate
threats have been addressed.
5. Which practice is most effective for preventing transmission
of infection between patients?
A. Wearing the same gloves between patients if they appear
clean
B. Performing appropriate hand hygiene at the indicated times
C. Wearing two pairs of gloves continuously
D. Using antibiotics before every patient encounter
Correct answer: B. Performing appropriate hand hygiene at
the indicated times
Rationale: Hand hygiene is a fundamental component of
infection prevention and is required before and after
appropriate patient-care activities, including situations
involving contact with potentially contaminated surfaces or
body substances. Gloves do not replace hand hygiene and must
be changed appropriately between patients and tasks.
