question 14
1 pts
an 18 year old patient who has undergone surgical immobilization for a femur fracture two
weeks ago, reports dyspnea and chest pain associated with inspiration. the patient has a
heart rate of 120 beats per minute. which diagnostic test will confirm the presence of a
pulmonary embolism (pe)?
o arterial blood gases (abgs)
o computed tomography (ct) angiography
o d-dimer
o electrocardiogram (ecg)
previous

Explanation:

• Arterial blood gases (ABGs) show oxygen and carbon dioxide levels but do not confirm PE.
• Computed tomography (CT) angiography directly visualizes pulmonary arteries and can show emboli.
• D - dimer is a screening test (elevated in many conditions, not confirmatory).
• Electrocardiogram (ECG) shows heart rhythm/electrical changes but not PE itself.

Answer:

Computed tomography (CT) angiography.
