Answer to Question 1

Correct Answer: 1, 2, 3

Titers between 1:20 and 1:80 may be present in autoimmune disorders and diseases such as leukemia, liver cirrhosis, and renal disease. A rheumatoid factor titer of 1:80 or higher indicates rheumatoid arthritis. A rheumatoid factor is not diagnostic for systemic lupus erythematosus.

Answer to Question 2

Correct Answer: 1, 3, 4, 5

A change in level of consciousness (lethargy, apprehension, or agitation) is often the first indicator of decreased cardiac output. As cardiac output drops, peripheral vessels constrict and tissue perfusion is impaired. The glomerular filtration rate (GFR) also falls; with an output of less than 30 mL/h, the patient is at risk for acute kidney injury from ischemia. A fall in blood pressure may indicate shock. Pruritus is not an indication of an alteration in cardiac output.
