A patient is admitted with esophageal varices and portal hypertension. Which underlying cause of these conditions would the nurse suspect?
Liver cirrhosis
Throat lacerations
Kyphosis
Squamous cell cancer
The Correct Answer is A
Choice A rationale
Liver cirrhosis is the most common cause of esophageal varices and portal hypertension. Cirrhosis leads to scarring of the liver, which impedes blood flow through the portal vein, causing increased pressure (portal hypertension) and the development of collateral blood vessels (varices) as the body attempts to bypass the blockage.
Choice B rationale
Throat lacerations are not related to the development of esophageal varices or portal hypertension. They are typically acute injuries and do not cause the chronic changes seen in the vasculature associated with these conditions.
Choice C rationale
Kyphosis, a curvature of the spine, does not cause esophageal varices or portal hypertension. It is a structural skeletal condition and does not affect the vasculature of the esophagus or the portal venous system.
Choice D rationale
While squamous cell cancer can occur in the esophagus, it is not a typical cause of portal hypertension or esophageal varices. These varices are usually a result of increased pressure in the portal vein, not directly from a malignancy.

Correct Answer is ["A","B","D"]
Explanation
Choice A rationale
Smoking is a well-established risk factor for colorectal cancer. The carcinogens in tobacco smoke can lead to the formation of cancerous cells in the colon and rectum.
Choice B rationale
Obesity increases the risk of colorectal cancer, possibly due to chronic low-level inflammation associated with excess body fat, which can contribute to cancer development.
Choice C rationale
Limiting alcohol intake to less than four drinks per week is actually a protective measure against colorectal cancer, not a risk factor.
Choice D rationale
A high intake of red meat, particularly more than seven servings per week, has been linked to an increased risk of colorectal cancer due to compounds formed during digestion that can damage the lining of the colon and rectum.
Choice E rationale
A diet high in fruits, vegetables, and grains is generally considered protective against colorectal cancer due to the fiber and nutrients they provide, not a risk factor.
Correct Answer is A
Explanation
Choice A rationale
In the case of hyperkalemia, which can cause fatal cardiac arrhythmias, the most immediate nursing action is to place the patient on a cardiac monitor. This allows for continuous monitoring of the heart's rhythm and immediate detection of any life-threatening changes, which is crucial for timely intervention.
Choice B rationale
Inserting a urinary retention catheter may be necessary for managing oliguria, but it is not the most urgent action when compared to the potential cardiac risks associated with hyperkalemia.
Choice C rationale
Administering spironolactone, a potassium-sparing diuretic, could be part of the treatment for hyperkalemia, but it is not the first action to take. Spironolactone works more slowly and does not address the immediate risk of cardiac arrhythmias.
Choice D rationale
Epoetin alfa (Epogen) is used to treat anemia, particularly in chronic kidney disease, to increase red blood cell production. However, it does not have an immediate effect and is not the priority in the presence of hyperkalemia and potential cardiac complications.
