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)
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 B
Explanation
A. Instruct the client to dig their heels into the bed to push themselves upwards: This increases friction on the heels, which can lead to skin breakdown.
B. Assist the client with a trapeze to raise their body while staff assists with repositioning. Using a trapeze allows the client to lift themselves slightly off the bed, reducing the friction and shear forces that can cause skin injuries during repositioning.
C. Have two to three staff members pull the client up in bed when needed: This increases the risk of friction injuries, especially if the client is not lifted properly.
D. Elevate the head of the bed 90° for bedridden clients: High elevation of the bed can increase the risk of shear injuries due to sliding down in bed.
Correct Answer is C
Explanation
A. Cashews: Cashews contain iron, but the amount is relatively low compared to other sources like red meat.
B. Oranges: Oranges are high in vitamin C, which aids iron absorption, but they are not a significant source of iron.
C. Red meat: Red meat is an excellent source of heme iron, which is highly bioavailable and effectively addresses iron deficiency.
D. Yogurt: Yogurt is not a significant source of iron. It contains other nutrients, but it is not relevant for increasing iron intake.
