A client presents to the emergency department with suspected pulmonary embolism. What blood test can help assess the likelihood of pulmonary embolism and its severity?

Complete blood count (CBC)

Arterial blood gas (ABG) analysis

D-dimer assay

Creatine kinase (CK) levels

Answer and Explanation

The Correct Answer is C

A) Incorrect. A complete blood count (CBC) provides information about the composition of blood cells but is not specific to pulmonary embolism.

B) Incorrect. Arterial blood gas (ABG) analysis helps assess oxygen and carbon dioxide levels but is not a primary test for diagnosing pulmonary embolism.

C) Correct. The D-dimer assay measures a substance released when a blood clot breaks up. Elevated D-dimer levels can suggest the presence of a blood clot, but it is not specific to pulmonary embolism.

D) Incorrect. Creatine kinase (CK) levels are used to assess muscle damage and are not a primary test for diagnosing pulmonary embolism.

Correct Answer is C

Explanation

A) Incorrect. An IVC filter is not used to administer anticoagulant medications but rather to prevent blood clots from reaching the pulmonary circulation.

B) Incorrect. IVC filters are not used to prevent airway obstruction.

C) Correct. The primary purpose of an IVC filter is to capture and prevent blood clots from reaching the pulmonary circulation, reducing the risk of pulmonary embolism.

D) Incorrect. IVC filters are not used to deliver oxygen directly to the lungs but rather to prevent emboli from reaching the lungs.

A. "A pulmonary embolism directly affects the bronchial tubes, causing airway constriction." B. "It primarily causes inflammation in the alveoli, leading to impaired oxygen exchange." C. "Pulmonary embolism disrupts blood flow to the lung tissue, reducing oxygen supply." D. "The condition leads to excessive mucus production, obstructing the air passages."

Correct Answer is C

Explanation

A) Incorrect. Pulmonary embolism does not directly affect the bronchial tubes or cause airway constriction.

B) Incorrect. While inflammation can occur as a response to pulmonary embolism, its primary impact is on blood flow, not the alveoli.

C) Correct. The main effect of pulmonary embolism is the disruption of blood flow to lung tissue, reducing oxygen supply.

D) Incorrect. Excessive mucus production is not a characteristic effect of pulmonary embolism.
