A female patient with a suspected urinary tract infection is to provide a clean-catch midstream urine specimen for culture and sensitivity testing. What should the nurse do to obtain the specimen?
Tell the patient to clean the urethral area, void a small amount into the toilet, then void directly into a sterile container.
Have the patient empty the bladder completely; then obtain the next urine specimen that the patient is able to void.
Clean the area around the patient's meatus with a povidone-iodine (Betadine) swab and then have the patient void into a sterile specimen cup.
Insert a short sterile "mini" catheter attached to a collecting container into the urethra and bladder to obtain the specimen.
The Correct Answer is A
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","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 B
Explanation
Choice A rationale
A history of high blood pressure is a risk factor for chronic kidney disease but not specifically for acute glomerulonephritis. Acute glomerulonephritis is more commonly associated with infections.
Choice B rationale
A recent sore throat and fever, especially if caused by a streptococcal infection, can lead to post-streptococcal glomerulonephritis. This is a well-documented cause of acute glomerulonephritis, making it the correct answer.
Choice C rationale
While bladder infections can lead to urinary tract infections, they are not typically associated with acute glomerulonephritis. This condition is more commonly related to infections that can cause a systemic immune response.
Choice D rationale
A history of kidney stones is associated with chronic kidney issues and can lead to infections, but it is not a direct cause of acute glomerulonephritis. This condition is usually caused by an immune response to an infection elsewhere in the body.
