A nurse is caring for a client who has developed pulmonary embolism (PE). Which of the following diagnostic tests should the nurse anticipate the provider to prescribe to confirm the client's condition?(Select All that Apply.)

D-dimer blood test

Complete blood count (CBC)

CT scan

Chest x-ray

Lung ventilation and perfusion scan (VQ scan)

Answer and Explanation

Correct Answer : A,C,E

A. D-dimer blood test - A D-dimer test measures clot breakdown products in the blood. Elevated levels suggest the presence of an abnormal blood clot, such as in PE, although it is not specific.

B. Complete blood count (CBC) - A CBC is not typically used to diagnose PE. It may be ordered to check for other conditions or as part of the overall health assessment, but it doesn't confirm PE.

C. CT scan - A CT pulmonary angiography is the gold standard for diagnosing PE. It provides detailed images of the blood vessels in the lungs.

D. Chest x-ray - A chest x-ray is not diagnostic for PE. It is often performed to rule out other causes of the client’s symptoms (e.g., pneumonia, pneumothorax) but does not confirm the presence of a pulmonary embolism.

E. Lung ventilation and perfusion scan (VQ scan)
A VQ scan is another diagnostic tool for PE, especially in clients who cannot tolerate contrast dye required for CT scans. It assesses the ventilation and perfusion of the lungs and identifies mismatches suggestive of PE.

Correct Answer is A

Explanation

A. Airway obstruction - Burns on the head, neck, and chest pose a high risk for airway obstruction due to swelling and potential inhalation injury. Ensuring a patent airway is the priority as it is critical for oxygenation and survival.

B. Paralytic ileus - While possible, a paralytic ileus is not an immediate life-threatening condition compared to airway obstruction.

C. Infection - Infection is a significant concern in burn patients, but it is a secondary priority after securing the airway.

D. Fluid imbalance - Fluid management is crucial in burn care, but securing the airway takes precedence due to the immediate risk to life from airway obstruction.

A. "Vision changes occur suddenly due to complete obstruction of aqueous humor outflow" B. Vision changes occur when retinal tissue pulls away from the blood vessels in the eye " C. Vision changes occur when the retina gins to breakdown and collect bits of debris D. Vision changes occur when the cloudy lens alters the passage of light through the eye”

Correct Answer is B

Explanation

A. "Vision changes occur suddenly due to complete obstruction of aqueous humor outflow." This describes acute angle-closure glaucoma, not retinal detachment.

B. "Vision changes occur when retinal tissue pulls away from the blood vessels in the eye." Retinal detachment happens when the retina separates from its supporting tissues, including the blood vessels, leading to vision loss.

C. "Vision changes occur when the retina begins to break down and collect bits of debris." This describes age-related macular degeneration, not retinal detachment.

D. "Vision changes occur when the cloudy lens alters the passage of light through the eye." This describes cataracts, not retinal detachment.
