The healthcare provider prescribes diagnostic tests for a patient whose chest x-ray indicates pneumonia. Which diagnostic test should the nurse prepare the patient for?

Computerized tomography (CT) of the chest.

Arterial blood gases (ABG).

Sputum culture and sensitivity.

Blood cultures.

Answer and Explanation

The Correct Answer is C

Choice A rationale
A CT scan of the chest can be performed to detect the severity of infection in pneumonia. However, it is not typically the first diagnostic test prescribed. It is usually recommended if the pneumonia isn’t clearing as quickly as expected.
Choice B rationale
Arterial blood gases (ABG) can be used to measure the oxygen level in your blood. Pneumonia can prevent your lungs from moving enough oxygen into your bloodstream. However, ABG is not typically the first diagnostic test prescribed for pneumonia.
Choice C rationale
A sputum culture test is often used to confirm the cause of infection in pneumonia. This test involves taking a sample of fluid from your lungs (sputum) after a deep cough and analyzing it to help pinpoint the cause of the infection.
Choice D rationale
Blood cultures can identify the germ causing your pneumonia and also show whether a bacterial infection has spread to your blood. However, they are not typically the first diagnostic test prescribed for pneumonia.

Correct Answer is C

Explanation

Choice A rationale
While lean beef, salads, and baked potatoes can be part of a balanced diet, they do not specifically target the prevention of colon and rectal cancers. Red meat, in particular, has been associated with an increased risk of colorectal cancer.
Choice B rationale
Potatoes, low-fat breads, and applesauce can be part of a balanced diet, but they do not specifically target the prevention of colon and rectal cancers. A diet rich in whole grains, fruits, and vegetables is more beneficial.
Choice C rationale
A diet rich in oatmeal, raisins, and fruit with skin is high in fiber and antioxidants, which can help reduce the risk of colon and rectal cancers. This is especially important for clients with a strong family history of these cancers.
Choice D rationale
Chicken, rice, and wheat products can be part of a balanced diet, but they do not specifically target the prevention of colon and rectal cancers. A diet rich in whole grains, fruits, and vegetables is more beneficial.

A. Chronic insomniais not a critical side effect of phenytoin and may be managed with lifestyle modifications or further assessment.
B. Puffy, bleeding gumsare common side effects associated with phenytoin (gingival hyperplasia) but are not immediately life-threatening.
D. Blood pressure 100/78 mm Hgis within normal limits and does not indicate a need for urgent action
