An hour after administering 60 mg of furosemide intravenously (IV), which assessments should the nurse perform to determine the patient’s response to treatment? (Select all that apply.)

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.

Choice A rationale
While the renin-angiotensin response can be affected in cirrhosis, it is not the primary mechanism contributing to edema and ascites. In cirrhosis, there can be a decrease in renal blood flow which can lead to activation of the renin-angiotensin system, but this is not the main cause of fluid accumulation.
Choice B rationale
Hypoalbuminemia, or low levels of albumin in the blood, is a common occurrence in cirrhosis. Albumin is a protein that helps maintain oncotic pressure, which keeps fluid in the blood vessels. When albumin levels are low, fluid can leak out of the blood vessels and accumulate in the abdomen (ascites) and in the tissues, causing edema.
Choice C rationale
Hyperaldosteronism can occur in cirrhosis and can contribute to fluid retention. However, it is not the primary mechanism leading to edema and ascites. Aldosterone promotes sodium and water reabsorption in the kidneys, which can contribute to fluid retention, but this is usually a secondary response to other changes in the body.
Choice D rationale
Decreased portacaval pressure with greater collateral circulation is not the primary mechanism contributing to edema and ascites in cirrhosis. While portal hypertension is a common complication of cirrhosis, it is not directly responsible for the development of edema and ascites.
