The nurse is discussing bowel elimination habits with a client.
Which item is considered a gas-producing food?
Cabbage.
Oranges.
Green leafy vegetables.
Coffee.
The Correct Answer is A
Choice A rationale
Cabbage contains complex carbohydrates, such as raffinose, that the human body cannot easily digest in the small intestine. When these undigested sugars reach the large intestine, they are fermented by bacteria, which produces gases such as methane, carbon dioxide, and hydrogen. This process often leads to abdominal bloating and flatulence. Therefore, clients who are experiencing excessive gas or who have had recent abdominal surgery are often advised to limit their intake of cruciferous vegetables.
Choice B rationale
Oranges are primarily a source of simple sugars, water, and Vitamin C. While they contain fiber, they do not have the same high concentration of non-digestible complex carbohydrates found in gas-producing vegetables. Citric acid in oranges might cause gastric irritation or reflux in some sensitive individuals, but they are not typically classified as a primary gas-producing food in the same category as beans or cabbage. They are generally considered safe for those trying to avoid flatulence.
Choice C rationale
Green leafy vegetables, such as spinach or lettuce, are high in insoluble fiber and water. While they are excellent for promoting regular bowel movements and preventing constipation, they do not typically undergo the same heavy bacterial fermentation process that produces significant amounts of gas. Most green leafy vegetables are well-tolerated by the digestive system. They provide essential nutrients without the common side effect of significant bloating or gaseous distention often seen with broccoli or cabbage.
Choice D rationale
Coffee is a stimulant that can increase gastric motility and lead to more frequent bowel movements due to its caffeine content. While it can cause some individuals to experience stomach upset or increased acidity, it is not a gas-producing food. The primary effect of coffee on the gastrointestinal system is the stimulation of the smooth muscles in the colon, which speeds up the transit time of stool rather than increasing the production of intestinal gases through bacterial fermentation.

Correct Answer is D
Explanation
Step 1 is 1000 mL ÷ 125 mL/hr = 8 hr.
Step 2 is 0900 + 8 hr = 1700. Final calculated answer is 1700.
Correct Answer is ["A","B","C","D","E"]
Explanation
Choice A rationale
Cleaning and irrigating the wound with a non-antimicrobial solution like normal saline is necessary to remove surface contaminants, debris, and necrotic tissue. This ensures that the swab collects the actual pathogens causing the deep tissue infection rather than superficial skin flora. Normal saline is preferred because it does not inhibit bacterial growth on the culture medium, whereas antiseptic solutions might yield false negative results by killing the microbes before they reach the laboratory.
Choice B rationale
The use of personal protective equipment including gloves, gowns, and face masks is a standard precaution when there is a high risk of splashing or aerosolization of blood or body fluids. Collecting blood and swabbing a wound involves close contact with potentially infectious materials. These barriers protect the healthcare worker from exposure to bloodborne pathogens and prevent the cross-contamination of microorganisms between the patient and the provider during the collection of these critical diagnostic specimens.
Choice C rationale
Sterile gloves are required when performing a blood culture draw to maintain a surgically aseptic field during the palpation of the vein and the insertion of the needle. Unlike clean gloves used for standard venipuncture, sterile gloves minimize the risk of introducing skin commensals like Staphylococcus epidermidis into the culture bottles. Contaminated blood cultures lead to misdiagnosis, unnecessary antibiotic use, and increased hospital costs, so maintaining strict sterility throughout the entire procedure is an essential practice.
Choice D rationale
Thoroughly cleaning the skin with an antiseptic agent such as chlorhexidine gluconate or povidone-iodine is the most critical step in preventing specimen contamination. The skin must be scrubbed vigorously for at least 30 seconds to reach the deeper layers of the epidermis where bacteria reside. This process significantly reduces the presence of transient and resident flora, ensuring that any organisms detected in the blood culture are truly originating from the patient's bloodstream and not the skin.
Choice E rationale
Changing gloves between different procedures, such as moving from a wound swab to a blood draw, is mandatory to prevent the mechanical transfer of pathogens from one body site to another. Wounds are often colonized with high concentrations of bacteria that could contaminate the blood culture site if the same gloves are used. Adhering to hand hygiene and changing gloves ensures the integrity of each individual specimen and prevents the introduction of new infections into the client.
