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
Explanation
Choice A rationale
This method is the standard procedure for obtaining a clean-catch midstream urine specimen. The initial voiding washes away organisms near the meatus, and the midstream urine is less likely to be contaminated by bacteria from the skin or urethral area, providing a sample that more accurately represents the bacteria in the bladder.
Choice B rationale
Having the patient empty the bladder completely and then obtaining the next specimen does not ensure a clean-catch sample. This method could lead to contamination of the specimen with bacteria from the skin or urethral area.
Choice C rationale
Cleaning the area with povidone-iodine is not recommended for routine urine culture as it may kill some of the bacteria, leading to a false-negative result. The standard practice is to clean the area with mild soap and water.
Choice D rationale
Inserting a catheter is an invasive procedure and is not the first choice for obtaining a urine specimen. It is used when a patient is unable to provide a clean-catch specimen or if there are specific medical indications.
Correct Answer is ["A","B","C","E"]
Explanation
Choice A rationale
Proteinuria, or the presence of an abnormal amount of protein in the urine, is a hallmark sign of glomerulonephritis. It occurs due to the increased permeability of the glomerular filtration barrier.
Choice B rationale
Hypertension is often associated with glomerulonephritis. The damage to the glomeruli can lead to salt and water retention, contributing to high blood pressure.
Choice C rationale
Periorbital edema, which is swelling around the eyes, is a common early symptom of glomerulonephritis. It is caused by fluid retention and leakage into the tissue.
Choice D rationale
Hypotension is not typically associated with glomerulonephritis. In fact, hypertension is more common due to the reasons mentioned above.
Choice E rationale
Hematuria, or blood in the urine, is another common finding in glomerulonephritis. It results from the inflammation and damage to the glomeruli, allowing red blood cells to leak into the urine.
