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.
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 B
Explanation
Choice A rationale
While monitoring skin for breakdown is an important aspect of nursing care, especially for bedridden or immobile patients, it is not the most important intervention for a client admitted with possible anastomosis leakage.
Choice B rationale
An anastomotic leak is a serious complication that occurs when the surgical connection between two parts of the intestine leaks, allowing the contents of the gastrointestinal tract to leak into the abdominal cavity. This can lead to serious infection and sepsis. Strict intravenous
(IV) fluid replacement is crucial in this situation to prevent dehydration and maintain blood pressure.
Choice C rationale
Encouraging regular turning is an important aspect of nursing care to prevent pressure ulcers, especially for bedridden or immobile patients. However, it is not the most important intervention for a client admitted with possible anastomosis leakage.
Choice D rationale
Assessing wound drainage daily is an important aspect of postoperative care. However, in the case of a suspected anastomotic leak, more immediate and critical interventions are required.
Correct Answer is C
Explanation
Guillain-Barre syndrome is a disorder in which the body’s immune system attacks the nerves, causing weakness and tingling, usually starting in the legs and hands. A loss of sensation, especially at the T-8 spinal level, could indicate that the syndrome is progressing, potentially leading to paralysis. This would require immediate intervention by the nurse to prevent further complications.
