A nurse is educating the public at a health fair about colorectal cancer. Which of the following risk factors increase the risk of developing colorectal cancer? (Select all that apply.)
Smoking
Obesity
Limiting alcohol intake to less than four drinks per week
More than seven servings of red meat per week
A diet high in fruits, vegetables, and grains
Correct Answer : A,B,D
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
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","C","E"]
Explanation
Choice A rationale
Immobility is a significant risk factor for DVT as it can lead to stagnation of blood in the veins, increasing the risk of clot formation.
Choice B rationale
High calcium intake is not typically associated with an increased risk of DVT. Instead, factors like immobility, certain medications, and medical conditions are more influential.
Choice C rationale
Oral contraceptive use, especially those containing estrogen, can increase the risk of DVT due to their effect on blood clotting mechanisms.
Choice D rationale
A BMI of 20 is considered within the normal range and is not a risk factor for DVT. Obesity, which is a BMI of 30 or higher, would be a risk factor.
Choice E rationale
Hypertension itself is not a direct risk factor for DVT. However, it can be associated with other health conditions that may increase the risk of thrombosis.
