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 A
Explanation
Choice A rationale
The client’s presentation of chest pain radiating to the left arm, shortness of breath, and diaphoresis are classic symptoms of a myocardial infarction (heart attack)56. Morphine is often administered in this situation to relieve pain and reduce the workload of the heart.
Choice B rationale
Oxycodone is a strong opioid medication used to treat severe pain. However, it is not typically the first choice for pain relief in the setting of a suspected heart attack.
Choice C rationale
Hydromorphone is another strong opioid medication used to treat severe pain. Like oxycodone, it is not typically the first choice for pain relief in the setting of a suspected heart attack.
Choice D rationale
Fentanyl is a potent opioid pain reliever. While it can be used in the management of severe pain, it is not typically the first choice for pain relief in the setting of a suspected heart attack.
Correct Answer is D
Explanation
Choice A rationale
Antibiotics are typically used to treat bacterial infections, not fungal infections like athlete’s foot. Therefore, using antibiotics would not be effective in this case.
Choice B rationale
While it’s important to use treatments for the full recommended duration to ensure the infection is completely eradicated, using an antibiotic ointment for a fungal infection like athlete’s foot would not be effective.
Choice C rationale
While it’s true that applying too much ointment can deter its effectiveness, the main issue here is that an antibiotic ointment is not the correct treatment for a fungal infection like athlete’s foot.
Choice D rationale
Athlete’s foot is a fungal infection that thrives in warm, moist environments. Therefore, keeping the feet dry and clean is an important part of managing and preventing athlete’s foot. This includes wearing clean socks and allowing the feet to dry completely before putting on shoes.
