1. Which physiological parameter is most important to assess before
an MRI examination in a patient who is acutely ill?
A. Hair color
B. Height
C. Hemodynamic stability
D. Hand dominance
Answer: C. Hemodynamic stability
Rationale: Hemodynamic stability is essential before imaging because
an unstable patient may deteriorate during transport or examination
and may require immediate intervention. Blood pressure, heart rate,
oxygenation, perfusion, and overall clinical status should be
considered before proceeding.
2. Which structure is primarily responsible for oxygen exchange in
the lungs?
A. Alveoli
B. Bronchi
C. Trachea
D. Pleura
Answer: A. Alveoli
,Rationale: Alveoli are microscopic air sacs where oxygen diffuses into
pulmonary capillary blood and carbon dioxide diffuses out. The
bronchi and trachea conduct air but are not the primary sites of gas
exchange.
3. A patient becomes suddenly confused during an imaging
procedure. What should be assessed first?
A. Recent dietary intake
B. Airway, breathing, and circulation
C. Family medical history
D. Preferred sleeping position
Answer: B. Airway, breathing, and circulation
Rationale: Acute clinical deterioration requires immediate assessment
of ABCs. Airway obstruction, inadequate ventilation, or circulatory
compromise can rapidly become life-threatening and take priority over
obtaining a detailed history.
4. Which cardiac chamber pumps oxygenated blood into the systemic
circulation?
A. Right atrium
B. Right ventricle
C. Left atrium
D. Left ventricle
Answer: D. Left ventricle
Rationale: The left ventricle ejects oxygenated blood through the aorta
into systemic circulation. The right ventricle pumps deoxygenated
blood to the pulmonary circulation, while the atria primarily receive
blood.
5. Which finding most strongly suggests hypoxemia?
,A. Warm skin
B. Increased appetite
C. Low oxygen saturation
D. Increased urine output
Answer: C. Low oxygen saturation
Rationale: Reduced oxygen saturation indicates decreased oxygen
content in arterial blood and may reflect hypoxemia. Clinical
manifestations can include dyspnea, cyanosis, confusion, restlessness,
and altered consciousness.
6. What is the primary function of the kidneys?
A. Produce bile
B. Regulate fluid, electrolyte, and waste balance
C. Store glucose
D. Exchange pulmonary gases
Answer: B. Regulate fluid, electrolyte, and waste balance
Rationale: The kidneys filter blood, remove metabolic waste, regulate
electrolytes and acid-base balance, control fluid volume, and
contribute to endocrine functions such as erythropoietin production
and vitamin D activation.
7. Which anatomical plane divides the body into right and left
portions?
A. Sagittal
B. Coronal
C. Transverse
D. Oblique
Answer: A. Sagittal
, Rationale: A sagittal plane divides the body into right and left portions.
A midsagittal plane divides it into approximately equal right and left
halves, whereas parasagittal planes produce unequal portions.
8. Which cranial nerve is primarily responsible for vision?
A. Facial nerve
B. Vestibulocochlear nerve
C. Trigeminal nerve
D. Optic nerve
Answer: D. Optic nerve
Rationale: Cranial nerve II, the optic nerve, transmits visual
information from the retina to the brain. Assessment of vision can
provide important neurological information.
9. Which condition is characterized by abnormally elevated blood
glucose?
A. Hypoxemia
B. Hyperkalemia
C. Hyperglycemia
D. Hypothermia
Answer: C. Hyperglycemia
Rationale: Hyperglycemia means blood glucose is above the normal
range. It commonly occurs in diabetes mellitus but can also arise from
stress, medications, endocrine disorders, and other conditions.
10. Which electrolyte abnormality can produce significant
cardiac conduction disturbances?
A. Mild hypochloremia
B. Hyperkalemia
