In which disease process should a nurse expect to see a patient with the presence of pitting edema?
Diabetes mellitus
Liver disease
End-stage renal disease
Colon cancer
The Correct Answer is B
Choice A reason:
Diabetes mellitus is not typically associated with pitting edema unless it has led to a comorbid condition such as heart failure or kidney disease. Pitting edema is more commonly associated with fluid retention due to the body's inability to manage fluid balance, which is not a direct consequence of diabetes mellitus itself.
Choice B reason:
Liver disease, particularly cirrhosis, can lead to pitting edema. The liver's inability to produce albumin, a protein that helps maintain oncotic pressure in the blood vessels, and portal hypertension, which is an increase in the blood pressure within the portal vein system, can both contribute to the development of pitting edema.
Choice C reason:
End-stage renal disease can also cause pitting edema due to the kidneys' inability to excrete excess fluid. However, the edema associated with renal disease is often more generalized and not limited to the lower extremities.
Choice D reason:
Colon cancer is not typically associated with pitting edema unless it has metastasized and caused secondary complications that affect the liver or the heart. Pitting edema is not a direct symptom of colon cancer itself.

Correct Answer is B
Explanation
Choice A Reason:
Angular cheilitis is characterized by inflammation of one or both corners of the mouth. It often presents as red, swollen patches in the corners of the mouth and can be associated with fungal or bacterial infection. However, it does not typically cause vesicular eruptions, which are more indicative of viral infections like herpes simplex.
Choice B Reason:
Herpes simplex virus (HSV) is known for causing vesicular eruptions, commonly referred to as cold sores or fever blisters, around the lips and mouth area. These eruptions are fluid-filled blisters that can be painful and are highly indicative of an HSV infection, particularly HSV type 1, which commonly affects the oral region.
Choice C Reason:
Angioedema involves the rapid swelling of the deeper layers of the skin, often seen with hives. While it can affect the lips and surrounding areas, it does not cause vesicular eruptions. Angioedema is more associated with allergic reactions and can be part of anaphylaxis, a severe systemic reaction.
Correct Answer is A
Explanation
Choice a reason:
The oral mucosa is the most reliable area to evaluate for central cyanosis in a client with asthma. Central cyanosis reflects a decrease in arterial oxygenation and is best assessed where the blood flow is high and the skin is thin, which is the case with the oral mucosa. It is less likely to be affected by peripheral factors such as temperature and is therefore a more accurate indicator of oxygen saturation in the central circulation.
Choice b reason:
While ear lobes can show signs of cyanosis, they are not the most reliable indicator of central cyanosis because they are more prone to peripheral cyanosis. Peripheral cyanosis can occur in the ear lobes due to local vasoconstriction or decreased blood flow, which may not reflect central oxygenation levels.
Choice c reason:
The soles of the feet are not a reliable indicator of central cyanosis, especially in a client with asthma. The skin on the soles is thicker and has less blood flow compared to the oral mucosa, making it a poor site for assessing central cyanosis. Additionally, the soles can be affected by peripheral factors like pressure and temperature.
Choice d reason:
Conjunctivae are not the most reliable indicator of central cyanosis. While they can show signs of cyanosis, the assessment can be affected by environmental factors and the presence of blood vessels in the conjunctiva that may not accurately reflect central oxygenation levels.
